热加工弹性体组合物的方法和具有改进可加工性的弹性体组合物 Thermal processing method elastomer composition and an elastomer composition having improved processability

本发明的领域本发明涉及弹性体组合物和改进弹性体组合物的热处理的方法。 Field of the Invention The present invention relates to elastomer compositions and improved method of heat treatment of the elastomer composition.

本发明的背景今天许多产品需要高度工程技术加工的弹性组分,同时必须在与有限的使用或一次性使用一致的成本下生产出来。 Background of the Invention Today, many products require a high degree of engineering and technical processing of elastic components, and must be produced in line with the limited use or disposable costs. 对于有限的使用或一次性(使用),这指该产品和/或组分在被废弃之前仅仅使用少数几次或可能仅仅使用一次。 For limited use or disposable (use), this means that the product and / or components before being discarded or used only few times might only be used once. 此类产品的例子包括,但不限于,个人护理用吸收性产品如尿布,训练裤,失禁用衣服,等等。 Examples of such products include, but are not limited to, personal care absorbent products such as diapers, training pants, incontinent garment, and the like. 这些产品能够将弹性膜,弹性织物,弹性长丝和/或弹性层压材料用作组分。 These products can be an elastic film, elastic fabric, the elastic filaments and / or elastic laminate material used as component.

弹性体长丝,弹性膜,弹性无纺布和弹性层压材料的生产已经伴随有通常仅仅在几个操作小时之后被挤出组合物在口模尖头上积聚引起停机时间从而需要清洗的顽固性问题。 Elastomeric filaments, an elastic film, elastic nonwoven fabric, and production of the elastic laminate has been accompanied usually only a few hours of operation after the extruded composition to accumulate on the die tip downtime caused thereby requiring cleaning of stubborn issues. 各种机理已知可以有利于用于聚合物材料的挤出的口模的清洗和维护,同时最大程度减少停工期。 A variety of mechanisms known to be beneficial for the extrusion of polymeric material die cleaning and maintenance, while reducing downtime maximum extent. 熔化聚合物通过口模挤出形成膜,线条,无纺织物纤维网幅,和其它成品聚合物形式。 Extruding the molten polymer to form a film, the lines, the nonwoven fabric fiber web, and other forms of finished polymers through a die. 特别对于含有弹性体的弹性聚合物组合物,当聚合物离开口模时,一些聚合物组合物粘附于口模开口或“口唇”上,积聚在口模的外表面上。 Especially for compositions containing elastomeric polymer elastomers, when the polymer exits the die, some of the polymer composition is adhered to the outer surface of the die opening or "lips", and accumulate in the mouth die. 模唇积聚物逐渐地增加,直到它积累到脱落的程度为止,可以引起在产品中的缺陷(它能够例如是在织构上的细斑或泪滴或其它有害影响)或引起产品的其它美观性能以及停机造成的其他缺点。 Die lip buildup is gradually increased until it accumulates to the extent of shedding up, can cause (e.g., it can be on a textured thin spots or tears or other adverse effects) in the product caused by a defect or other beauty product performance and other shortcomings of downtime. 在口模的设计和挤出组合物的选择上投入相当多的工程技术设计以便最大程度减少这一积聚物。 In the selection of design and extrusion die composition of the invested quite a lot of engineering design in order to minimize the build-up. 分歧,汇合,切成圆弧的,和有角度的模唇几何结构全部是被开发来最大程度减少这一积聚物的方法实例。 Differences, convergence, radiused, and angled lip geometry all been developed to minimize the buildup of an instance method. 然而,没有一种口模设计能够完全地消除它。 However, none of die design can completely eliminate it. 通常的做法是暂时停止该挤出操作以便在口模上进行维护,除去这一积聚物。 The usual practice is temporarily stopped for maintenance of the extruding operation on the die, remove this buildup. 停机不利地影响产品收率,提高成本和可能还不利地影响产品均匀性。 Stop adversely affect product yield, and may also improve the cost adversely affect product uniformity. 因此,理想的是最大程度减少停工。 Therefore, it is desirable to minimize downtime.

已经尝试了减少在挤出过程中挤出物污染物的口模唇积聚或聚集的方法。 Have been attempted to reduce the extrudate during the extrusion die lip build-up of contaminants or aggregation method. 例如,美国专利No.6,245,271描述了在采用具有约0.5密耳到约3密耳的曲率半径的口模唇的口模的挤出操作中减少口模唇积聚的方法。 For example, U.S. Patent No.6,245,271 describes a reducing die lip build-up in the use of about 0.5 mils to about 3 mils radius of curvature of the die lip of the die of the extrusion operation method. 理想的是开发一种减少在挤出过程中的口模唇积聚物的方法。 Desirable to develop a reduction in the extrusion process of the die lip buildup method. 特别地,也理想的是不需要现有设备的改进的一种减少在弹性体组合物的挤出过程中口模唇积聚物的方法。 In particular, it is desirable that an improved device does not require prior reduction of the die lip buildup during extrusion of the elastomer composition method.

另外,工业化生产方法通常在同一口模上制造在各种长丝基重范围内的多种产品,因此对于制造的宽加工窗口产生了需求。 In addition, industrial production methods usually manufactured in a variety of long-range heavy wire based on a variety of products in the same mouthful of mold, so for the manufacture of a wide processing window to generate demand. 例如,9克/每平方米(gsm)长丝片材能够在特定的产量下从口模中挤出。 For example, 9 g / m2 (gsm) filament sheet can be extruded from the die at a specific output. 为了提高长丝重量,在同一口模中需要更高的产量。 In order to increase the weight of the filament, in the same mold in a need for higher yield. 产量的增加使得剪切速率提高和在口模出口产生流动不稳定性。 Increase in production rate increased and the shearing flow instabilities generating in the die exit. 这一现象一般可从在挤出长丝的表面上的熔体裂纹或鲨鱼皮来看出。 This phenomenon is generally available from the extruded filament surface melt fracture or sharkskin view. 也理想的是提高该方法的产量范围,无需在多个口模上投资。 Also desirable to improve the yield range of the method, without having to invest in more than one die.

本发明现在参考一种制造包括从本发明的弹性体组合物挤出的弹性体长丝的垂直长丝层压材料的方法来进行描述。 Referring now to the present invention is a manufacturing method comprising the elastomer composition of the present invention is extruded elastomeric filaments vertical filament laminate be described. 所述的垂直长丝层压系统详细地描述在US专利申请出版物No.US 2002/0104608和PCT国际出版物No.WO 01/88245中,它们两者被引入这里供参考。 The vertical filament laminate system is described in detail in US Patent Application Publication No.US 2002/0104608 and PCT International Publication No.WO 01/88245, and both of them are incorporated herein by reference. 该方法生产出可拉伸的层压制品,后者能够用于各种应用,如在训练裤中的女子体操服和需要一定程度的弹性的其它产品。 The method for producing a stretchable laminate, which can be used for various applications, such as in the training pants in women leotard and requires a certain degree of flexibility of other products. 所述的垂直长丝层压机系统通过使用垂直地取向的工艺生产出可拉伸的层压材料。 The vertical filament of the system by using a laminator vertically oriented technology to produce a stretchable laminate.

具体地说,所述工艺使用挤出供应许多根的弹性连续长丝的线条,以便从本发明的弹性体组合物形成可拉伸的组件。 Specifically, the extrusion process serves many root elastic continuous filaments lines, so that the assembly is formed from a stretchable elastomeric composition of the present invention. 用于形成复合织物的连续长丝的实际数量可以根据在最终产品中所需的具体特性来变化。 The actual number of continuous filaments for forming a composite fabric may vary depending on the particular characteristics desired in the final product to change. 例如,每单位宽度的材料,可以使用多达215根单独的线条,在很多情况下超过100根线条,和总共至多2600根线条,或更多。 For example, the material per unit width, can use up to 215 separate lines, in many cases more than 100 lines, and a total of up to 2600 lines or more.

挤出机的口模可以相对于第一辊来定位,这样连续长丝在预定角度下会合该第一辊。 Extruder die can be positioned relative to the first roller, so that the first roll of continuous filaments joined at a predetermined angle. 这一线条材挤出几何结构对于将熔化挤出物沉积到旋转辊或鼓上是理想的。 This sheet extrusion line geometry for the molten extrudate is deposited onto a rotating roll or drum is desirable. 带角度的或有角的取向为长丝以某一角度从口模中串出进入到辊切点提供了机会,导致了改进的纺丝,更有效能量转移,和一般更长的口模寿命。 Or angular orientation angled as filaments from the die at an angle in the string out into the roller tangent point provides an opportunity, leading to improved spinning, more efficient energy transfer, and generally a longer die life . 这一构型允许长丝从口模中串出并按照相对直的轨迹接触到在辊面上的切点。 This configuration allows the filament from the die in the string out and follow a relatively straight trajectory to the tangent point roller contact surface. 在挤出机的口模出口与纵轴(或第一辊的水平轴,取决于在那一角度上进行测量)之间的角度可以小到几度或高达90。 In the extruder die exit and the vertical axis (or horizontal axis of the first roller, depending on the measurements at that angle) between the angle as small as a few degrees or as high as 90 . 例如,90的挤出物离去方向与辊的角度可通过将挤出机直接定位在第一辊的下游边缘之上并在挤出机上具有侧出口口模尖头来实现。 For example, the extrudate leaving an angle of 90 with the direction of the roll can be positioned directly by an extruder and a die tip having a lateral outlet on the extruder to achieve over the downstream edge of the first roller. 另外,可以使用与垂直方向之间的角度如约20,约35,或约45。 Further, the angle between the vertical direction may be used as about 20 , about 35 , or about 45 . 已经发现,当使用下面所解释的12根-长丝/英寸喷丝板孔密度时,大约45角度就允许该系统有效地操作。 It has been found that when using the explained below 12 - filaments / inch spinneret hole density is approximately 45 angle to allow the system to operate effectively. 然而,最佳角度将随着挤出物出口速度,辊速度,从口模到辊的垂直距离以及从口模中心线到辊的上死点的水平距离而变化。 However, the optimum angle will vary with the extrudate exit velocity, roll velocity, the vertical distance from the die roll to and from the die to the roll center line of the horizontal distance dead center varies. 最佳性能可通过使用各种几何结构来实现,导致改进的纺丝效率和减少的断丝。 Optimal performance can be achieved using a variety of geometries, resulting in improved efficiency and reduced spinning broken wires. 在很多情况下,这会导致潜在性地增加的辊包覆而导致更有效的能量转移和更长的口模寿命,归因于在挤出物离开挤出机口模的毛细管和行进到冷却辊时该挤出物的减少拉扯和剪切。 In many cases, this can lead to potentially increase the roll coating and lead to more efficient energy transfer and longer die life, attributed to the extrudate exiting the extruder die capillary and travels to the cooling The extrudate rollers pull and shear reduction. 一般地,包括以上所述的(聚)硅氧烷添加剂当中的一种的本发明的弹性体组合物具有改进的纺丝效率,减少的断丝,减少的挤出物拉扯和剪切,这是指与不包括此类(聚)硅氧烷添加剂的相同弹性体组合物相比。 Generally, the elastomeric composition comprises one or more of said (poly) siloxane of the additive of the present invention which has an improved spinning efficiency, reduce yarn breakage, decrease the extrudate pull and shear, which refers not include such the same elastomer composition (poly) siloxane additive compared.

携带该连续长丝的辊进行定位和操作,以便在连续长丝垂直地流过层压系统时引起该连续长丝被拉伸。 Carrying the continuous filaments roller positioning and operation, so that when flow through the continuous filaments vertically laminating system causes the continuous filaments is stretched. 当使用多个辊时,各相继的辊在方向上与紧在前的辊反转,这样连续长丝的线条可以从一个辊到另一个辊进行手动切断。 When using a plurality of rollers, each successive roll in the direction of the immediately preceding roll reverse, so the lines can be continuous filaments from one roller to another roller hand-off. 另外,各相继辊的速度可以与在前的辊有差异,以获得所需的拉伸和伸长率特性。 Further, each successive roller speed can be different from the first roll, to obtain the desired tensile and elongation properties. 例如,任何具体的辊可以在相当于任何在前辊的速度的1倍到10倍之间和更高倍下操作。 For example, any particular roller can operate at higher times between any of the front roller speed is equivalent to 1 to 10 times. 典型地,单独的控制器,如伺服电动机或翻转驱动器,可以用于对各辊进行速度控制并驱动各个辊。 Typically, a separate controller, such as a servo motor or inversion drive, may be used to control the speed of each roll and driving each roll. 当速度变化时,相继的辊可以在更快的速率下转动以便在线条在垂直工艺中向下运动时拉伸或伸长该线条。 When the speed changes, successive rollers may be rotated at a faster rate in order to stretch or elongation of the line when the line is moved downward in a vertical process. 另外,连续长丝最终缩减到大约0.008到0.040英寸直径的纤维尺寸,和有时候缩减到大约0.015到0.020英寸直径。 Further, the continuous filaments ultimately reduced to about 0.008 to 0.040 inches in diameter of fiber size, and sometimes reduced to a diameter of about from 0.015 to 0.020 inches.

用于将连续长丝输送到粘结位点的单独辊的数量可以根据在最终产物中所述的具体属性来变化。 The number of individual rolls delivered to the continuous filaments for bonding site may be according to the specific properties according to changes in the final product. 例如,可以使用至少四个辊--第一冷却(或定位)辊,第二冷却辊,第三未冷却辊,和第四未冷却辊。 For example, at least four rolls - a first cooling (or location) roll, a second cooling roll, not the third cooling roll and a fourth roll uncooled. 另外地,在将连续长丝供应到该系统的层压机部分中之前需要仅仅两个冷却辊,该层压机部分在辊隙中将纺粘面料粘结于连续长丝。 Further, prior to the continuous filaments supplied to the laminating machine of the system requires only two cooling rollers, the laminator nip portion bonded to spunbonded fabric of continuous filaments.

该辊可以进行等离子体涂敷以提供良好的防粘性能。 The roller may be plasma coated to provide good release properties. 另外,该辊可以另外有纹槽或通道以确保所挤出的连续长丝在各自长丝之间保持合适的分隔间距,这是指当该长丝在辊表面上通过和流过该系统时。 In addition, the roller may additionally have a groove or channel to ensure that the extruded continuous filaments between the respective filaments to maintain proper separation distance, which means that when the filaments on the roll surface and flow through the system by . 光滑辊可以用于一个或全部的辊。 Smooth roll can be used for one or all of the rollers. 对于使用等离子体涂敷的辊的情况,连续长丝不会象它们在光滑、无涂层的辊上那样滑动。 For the case of using a plasma coated roll, the continuous filaments as they will not slide as on smooth uncoated roll. 等离子体涂层抓住了该线条和促进在连续长丝线条之间的距离的增加均匀性。 Plasma coating grabbed the line and facilitate continuous filaments at a distance between the lines to increase uniformity.

各种机理可以用于骤冷连续长丝。 A variety of mechanisms can be used to quench continuous filament. 例如,外界空气能够被加压通向纤维,以便控制该纤维的硬化。 For example, the outside air can be pressed towards the fiber, in order to control the fiber hardening. 另外地,一个大的辊能够以足够的表面积使用,以便骤冷该纤维。 Additionally, a large roll to a sufficient surface area can be used to quench the fibers.

在通过一系列的辊和被拉伸后,连续长丝然后被输送到一个位置,这样在层压机区段中片材可以粘结于连续长丝上。 Through a series of rollers and is stretched, the continuous filaments and then supplied to a position such that in the laminator section sheet may be bonded to the continuous filaments. 这一片材的弹性低于连续长丝的弹性。 This elastic sheet is less than the elastic continuous filaments. 该片材可以是各种熔喷法无纺织物网幅,纺粘无纺织物网幅,梳理纤维网幅,或甚至机织纤维网幅。 The sheet may be a variety of meltblowing nonwoven fabric web, a spunbonded nonwoven fabric web, carded web, or even woven fibrous web. 然而,某些增强的性能和生产效率起因于聚合物纺粘无纺织物网幅的使用。 However, some enhanced performance and production efficiency caused by polymer spunbonded nonwoven fabric web is used. 在一个具体的实施方案中,可以使用具有大约0.4盎司/每平方码(“osy”)的基重的聚丙烯纺粘面料。 In a particular embodiment, may be used with about 0.4 oz / per square yard ("osy") of the basis weight of a polypropylene spunbond fabric.

粘结可以自生地实现或通过单独的粘合剂的使用或作为自生和粘合剂粘结的结合来实现。 Bonding may achieve self habitat or by the use of adhesives alone or as a combination of self-generated and adhesive bonding to achieve. 典型地,等连续长丝到达粘结站时该过程已经足够地骤冷该连续长丝,这样单独的自生粘合(或没有粘合剂的粘结)是不可能的。 Typically, etc. When the continuous filaments to reach the bonding process has been sufficiently station quenched continuous filament, such separate self adhesive (or no adhesive bond) is not possible. 典型地,使用粘合剂,如熔体喷射型粘合剂。 Typically, the use of adhesives, such as melt blown pressure-sensitive adhesive. 虽然,下面将解释,如果在面料中或在连续长丝中使用足够的增粘树脂,或其它粘合剂组分,则自生粘合是可能的。 Although, will be explained below, or using a sufficient if a tackifier resin in the fabric in a continuous filament, or other adhesive component, the autogenous bonding is possible.

粘合剂能够直接喷涂到将被粘结到连续长丝上的片材上。 Adhesive can be sprayed directly on to the sheet is bonded to the continuous filaments on. 然而,粘合剂施涂如刷涂或类似方法的其它排列也可以使用。 However, other arrangements a binder application methods such as brushing or the like may also be used. 另外,该粘合剂在片材与连续长丝粘结之前可以直接施涂到该片材上,可以在粘结之前施涂于连续长丝和片材上,或可以在施加粘结压力的同时施涂于长丝和片材之一或两者上。 Further, the adhesive sheet prior to bonding with the continuous filaments may be applied directly to the sheet, can be applied to the continuous filaments and sheet before bonding, or may be applied bonding pressure while applied onto one or both of the filaments and sheets. 本发明不局限于任何具体的粘结机理。 The present invention is not limited to any specific bonding mechanism.

可以使用的特殊熔体喷射型粘合剂包括Findley牌H2525A和Findley牌H2096,两者从Findley Adhesives(也已知为Bostik Findley)获得。 Special melt blowing type adhesives may be used include Findley H2525A cards and card Findley H2096, both (also known as Bostik Findley) obtained from Findley Adhesives. 这些粘合剂可以通过热熔体喷射口模在大约300-375F的升高温度下施涂到面料的内表面。 These adhesives can be sprayed die about 300-375 F at elevated temperatures is applied to the inner surface of the sheet by hot melt. 熔体喷射粘合剂通常在最终的复合材料上形成约3克/每平方米(“gsm”)粘合剂的重量非常轻的层。 Melt blown adhesive is generally from about 3 g / m2 weight ("gsm") of a very light layer of adhesive is formed on the final composite. 这些特殊的Findley粘合剂同样是弹性的。 These special Findley adhesive is also resilient.

该系统使用夹辊以便对粘合剂涂层面料和连续长丝施加压力,导致必要的层压。 The system uses a pair of nip rolls so that the adhesive coated fabric and continuous pressure applied to the filament length, resulting in the need for lamination. 外部面料与连续长丝在相当高的表面压力下粘结在一起,该压力可以在约20和300磅/每英寸(“pli”)之间。 External fabric with continuous filaments bonded together at a relatively high surface pressure which may be between ("pli") of about 20 and 300 lbs / per inch. 典型的粘结压力可以是约50pli或约100pli。 Typical bonding pressure may be about 50pli or about 100pli.

层压装置的粘结器或夹辊(有时称为“层压机”)区段在连续长丝上进行初级拉伸。 Laminator nip roll bonding or (sometimes called a "laminator") section in the preliminary stretch the continuous filaments. 粘结器或夹辊相对于冷却辊的速度比能够变化,和在大多数情况下在约2∶1到8∶1和在一些情况下是大约4∶1到6∶1。 Bonding or nip rolls with respect to the cooling roll speed ratio can be varied, and in most cases at about 2 to 8:1 and in some cases from about 4:1 to 6:1.

作为备选方案,弹性线条可以在拉伸之前粘结于聚合物网幅上,这样线条能够以单个片形式装运处置。 As an alternative, the elastic strips that are bonded to the polymeric web prior to stretching, so that lines can be shipped in a single piece in the form of disposal. 在这一方法中,增粘的熔喷法网幅可以施加到一组的平行弹性长丝之上。 In this method, the French tackified meltblown web may be applied onto a set of parallel elastic filaments. 网幅/线条片材将被拉伸和然后输送到压延机辊隙中以便利用粘合剂体系将面料粘结于片材上。 Web / lines sheet will be stretched and then transported to the calender nip in order to take advantage of the adhesive system will be adhered to the sheet on the fabric. 当使用时,这一特殊过程允许偶然的断丝或缺陷,但不中断该制造过程。 When used, this particular process allows the occasional broken wire or defects, but does not interrupt the manufacturing process.

在某些情况下,一种或多种的附加面料可以粘结于拉伸连续长丝的另一个独立的表面上以获得可拉伸的制品,其中连续长丝夹在至少两个外部面料之间。 In some cases, one or more additional fabric may be bonded to other continuous filaments drawn on a surface in order to obtain independent stretchable article, wherein the continuous filaments is sandwiched between at least two outer fabrics room. 再次,特殊的粘结机理和方法不受到本发明的教导的限制。 Again, special bonding mechanism and method is not limited by the teachings of the present invention. 在许多情况下,仅仅将喷射粘合剂施涂到一个外部面料的一个表面上,和然后让携带粘合剂的面料与拉伸连续长丝和与第二外部面料接触将会导致两者-面料/连续长丝层压产品有足够的粘结强度。 In many cases, only the ejecting adhesive applied to one surface of an outer fabric, and then let the adhesive carrying fabric stretching continuous filaments and the second outer fabric will result in contact between the two - Fabric / continuous filament laminated products have sufficient bond strength.

在将面料粘结于连续长丝上形成纺粘/弹性体连续长丝/纺粘层压材料后,然后让层压材料松驰和收缩到未拉伸或低拉伸的状态。 After the bond is formed spunbond fabric / elastomeric continuous filaments / spunbond laminate on a continuous filament, and then let the relaxation and contraction of the laminate to the unstretched or low-stretched state. 该层压材料经由表面驱动卷取机被卷绕到卷收辊上。 The laminate is wound via surface winder drive to roll retractors. 卷取机相对于粘结器的速度比导致拉伸连续长丝的松弛以及当层压材料卷绕到卷筒时导致层压材料收缩到褶裥状态。 Coiling machine's speed relative to the bond stretching ratio leads to relaxation and continuous filament winding reel when the laminate to laminate lead shrink to tuck state. 例如,该卷取机速度与粘结器辊速度之比可以是大约0.3比约1.0,并且可以是约0.5比1.0。 For example, the ratio of the speed of the bonder roll speed winder ratio may be about 0.3 to about 1.0, and may be about 0.5 to 1.0. 连续长丝的收缩导致得到褶裥的、可拉伸的层压制品,其中外部面料在粘结点之间褶裥。 The contraction causes the resulting continuous filaments are pleated, stretchable laminate, wherein the outer fabric gathers between bond points.

层压材料的整个基重能够发生变化,但是在一些应用中是在约2和约4盎司/每平方码(“oz/yd2”)之间。 Weight of the entire base laminate can vary, but in some applications is between about 2 and about 4 oz / per square yard ("oz / yd2"). 在一个特殊的实施方案中,该基重是在约2.85和约3.2oz/yd2之间。 In a particular embodiment, the base weight is between about 2.85 and about 3.2oz / yd2.

各种类型的组合物和各种加工条件可以用于形成弹性连续长丝。 Various types of compositions and a variety of processing conditions may be used to form an elastic continuous filaments. 例如,KRATONTM牌弹性聚合物可以输入到挤出机中,在其中聚合物在约260和460F之间的控制温度下,和在某些情况在大约385F下熔化。 For example, KRATONTM card elastomeric polymer may be input into an extruder in which the polymer at a controlled temperature of about 260 and 460 F between, and at about 385 F in some cases melted. 在其它实施方案中,取决于所使用的具体聚合物,熔融温度可以是大约470F到480F。 In other embodiments, the specific polymer depends on the melting temperature may be about 470 F to 480 F. 聚有机基硅氧烷的添加能够使挤出温度降低了50到100F。 Polyorganosiloxanes added enables the extrusion temperature was lowered 50 or 100 F. 聚合物然后在大约300到4000psi(典型地约1500到约2000psi)的压力下,经过在模头中的预定数量的孔沿着一般向下的方向挤出成单独的连续长丝。 Polymer and then at about 300 to 4000psi (typically about 1500 to about 2000psi) pressure, after a predetermined number of holes in the die extruded into a single continuous filaments along the generally downward direction. 正如下面所解释,各种的口模孔构型可以用于本发明中。 As explained below, a variety of die orifice configuration may be used in the present invention.

该面料可以是弹性和无弹性的纤维或颗粒物的混合物。 The fabric can be a mixture of elastic and inelastic fibers or particles. 例如,US专利No.4,209,563以全部内容被引入这里供参考并且描述了一种方法,利用该方法弹性体和非弹性体纤维杂混形成无规分散纤维的单个内聚型网幅。 For example, US Patent No.4,209,563 to the entire contents of which are incorporated herein by reference and describes a method, using this method elastomer and non-elastomeric fibers are formed of randomly dispersed fibers commingled single cohesive type web. 该弹性复合材料网幅的另一个实例已示于US专利No.4,741,949中,它同样地以全部内容引入这里供参考,其中弹性非编织材料被描述为包括熔喷法热塑性纤维和其它材料的混合物。 Another example of the elastic composite web has been shown in US Patent No.4,741,949, which in the same manner to the entire contents incorporated herein by reference, wherein the elastic nonwoven material is described as including a mixture of meltblown thermoplastic fibers and other materials, method of . 该纤维和其它材料在携带纤维的成形(forming)气流中相结合,这样在纤维收集在收集设备上形成无规分散纤维的内聚网幅之前发生了纤维和其它材料,例如木质纸浆,短纤维或颗粒状物(如活性炭,粘土,淀粉或水胶体(水凝胶)颗粒状物)的紧密的缠结杂混。 The combination of fibers and other materials in carrying the fibers forming (forming) stream, so that the collecting fiber fibers and other materials occurs prior to the randomly dispersed fibers cohesive web is formed on a collecting device, e.g., wood pulp, staple fibers or particulate matter (such as activated carbon, clays, starches, or hydrocolloid (hydrogel) particulates) tightly entangled commingled.

各种加工助剂也可添加到用于本发明中的弹性聚合物中。 A variety of processing aids can also be used in the present invention is added to the elastomeric polymer. 例如,聚烯烃可以与弹性聚合物(例如,ABA弹性体嵌段共聚物)共混,以改进组合物的可加工性。 For example, the polyolefin may be an elastic polymer (e.g., ABA elastomeric block copolymer) is blended in order to improve the processability of the composition. 聚烯烃应该是这样一种聚烯烃,当被共混并且经历高压和高温条件的合适结合时,可以与该弹性聚合物以共混形式被挤出。 The polyolefin should be such a polyolefin which, when blended and subjected to high pressure and high temperature conditions suitable combination, can be blended with the elastomeric polymer to form extruded. 有用的共混聚烯烃材料包括,例如,聚乙烯,聚丙烯和聚丁烯,包括乙烯共聚物,丙烯共聚物和丁烯共聚物。 Useful blending polyolefin materials include, for example, polyethylene, polypropylene and polybutene, including ethylene copolymers, propylene copolymers and butene copolymers. 特别有用的聚乙烯能够以商标标识Petrothene NA 601(在这里也称作PE NA 601或聚乙烯NA 601)从USIChemical Company获得。 Particularly useful polyethylene can trademark Petrothene NA 601 (also referred to herein PE NA 601 or polyethylene NA 601) obtained from USIChemical Company. 另一种建议的蜡包括从田纳西州Kingsport的Eastman Chemical获得的Elpolene C-10PE蜡。 Another suggestion waxes include Elpolene C-10PE wax obtained from Kingsport, Tennessee and Eastman Chemical. 可以使用两种或多种的聚烯烃。 Possible to use two or more polyolefins. 弹性聚合物和聚烯烃的可挤出共混物公开于,例如,US专利No.4,663,220,它被引入这里供参考。 Elastomeric polymers and polyolefins are disclosed in extrudable blend, for example, US Patent No.4,663,220, which is incorporated herein by reference.

用于形成熔体喷涂粘合剂和/或弹性体长丝的弹性体材料可具有足够的粘性以允许或增强自生粘结。 For forming a melt spray adhesive and / or elastomeric material of the elastomeric filaments may have sufficient tack to allow or enhance the autogenous bonding. 例如,当形成为纤维和/或长丝时弹性聚合物本身可以是粘性的,或另外地,相容的增粘树脂可以添加到可挤出的如上所述的弹性体组合物中以提供自生粘结的增粘弹性体纤维和/或长丝。 For example, when formed into fibers and / or filaments of the elastomeric polymer itself may be tacky, or in addition, a compatible tackifying resin may be added to the extrudable elastomeric compositions described above to provide a self-generated tackifying adhesive elastomeric fibers and / or filaments. 各种已知的增粘树脂和增粘的可挤出弹性体组合物都可以使用,如描述在US专利No.4,787,699中的那些,它以全部内容被引入这里供参考。 Various known tackifying resins and tackified extrudable elastomeric compositions may be used, such as those described in US Patent No.4,787,699 in, which is incorporated in its entirety herein by reference.

可以使用与弹性聚合物相容的并能够承受挤出加工条件的任何增粘剂树脂。 May be used is compatible with the elastomeric polymer and can withstand the extrusion processing conditions of any tackifier resin. 如果该弹性聚合物(例如,ABA弹性体嵌段共聚物)与加工助剂,例如聚烯烃或增量油,进行共混,则增粘剂树脂应该同样地与这些加工助剂相容。 If the elastomeric polymer (e.g., ABA elastomeric block copolymer) and processing aids, such as polyolefins or extending oils, blended, the tackifier resin should also be compatible with those processing aids. 一般,氢化烃树脂显示出增强的温度稳定性和,因此,是理想的增粘剂。 Usually, hydrogenated hydrocarbon resins exhibit enhanced temperature stability and, therefore, is the ideal tackifier. REGALREZTM烃树脂和ARKONTM系列增粘剂是氢化烃树脂的例子。 REGALREZTM hydrocarbon resin and ARKONTM series tackifiers are examples of hydrogenated hydrocarbon resins. ZONATAKTM501 lite是萜烃的一个例子。 ZONATAKTM501 lite is an example of a terpene hydrocarbons. REGALREZTM烃树脂可以从田纳西州Kingsport的Eastman ChemicalCompany获得。 REGALREZTM hydrocarbon resin available from Kingsport, Tennessee Eastman ChemicalCompany. ARKONTM系列树脂可以从Arakawa Chemical(USA)获得。 ARKONTM series resins available from Arakawa Chemical (USA). 当然,本发明不局限于此类增粘树脂的使用,并且也可以使用与该组合物的其它组分相容和能够承受加工条件的其它增粘树脂。 Of course, the present invention is not limited to use of such tackifying resins, and may also be used compatible with the other ingredients of the composition and can withstand the processing conditions of other tackifying resins.

在一个实施方案中,用于形成弹性体连续长丝以及面料的共混物包括,例如,约40-约80wt%弹性聚合物,约5-约40wt%聚烯烃,和约5-约40wt%树脂增粘剂。 In one embodiment, the elastomer used to form continuous filaments and fabric blends include, for example, from about 40 to about 80wt% elastomeric polymer, from about 5 to about 40wt% of polyolefin, and from about 5 to about 40wt% resin tackifier. 例如,具体的组合物可以包括,按重量,约61-约65%KRATONTM1657(在一种情况下,约63%),约17-约23%聚乙烯NA 601-04蜡(在一种情况下,约20%),和约15-约20%REGALREZTM1126(在一种情况下,约17%)。 For example, the particular composition may comprise, by weight, from about 61- to about 65% KRATONTM1657 (in one case, about 63%), from about 17 to about 23% NA 601-04 polyethylene wax (in one case , about 20%), and about 15 to about 20% REGALREZTM1126 (in one case, about 17%). KRATONTM1657是,尤其,苯乙烯-乙基丁烯-苯乙烯(S-EB-S)三嵌段基础橡胶聚合物。 KRATONTM1657 is particularly, styrene - ethyl butylene - styrene (S-EB-S) triblock rubber base polymer.

在另一个实施方案中,可以使用从Eastman Chemical Company ofKingsport,Tennessee获得的由大约85%AB-A'-B'四嵌段基础橡胶聚合物(由KRATONTMPolymers作为G1730销售)和15%EPOLENE C10聚乙烯蜡组成的聚合物共混物。 In another embodiment, can be used by obtained from Eastman Chemical Company ofKingsport, Tennessee about 85% AB-A'-B 'tetra-block based rubbery polymer (sold by KRATONTMPolymers as G1730) and 15% EPOLENE C10 polyethylene waxes polymer blends. 在这一具体情况下,在橡胶聚合物中的A和A'可以是含有苯乙烯结构部分的热塑性嵌段和B和B'可以是由聚(乙烯-丙烯)组成的弹性聚合物嵌段。 In this particular case, the rubber polymer A and A 'may be a thermoplastic block styrene moiety and B and B' may be made of poly - an elastic polymer block (ethylene propylene) thereof.

在附加的实施方案中,可以使用由大约80%AB-A'-B'四嵌段基础橡胶聚合物,7wt%的EPOLENE C10聚乙烯蜡,和13wt%的REGALREZTM1126增粘剂组成的另一种聚合物共混物。 In an additional embodiment, another may be used from about 80% AB-A'-B 'tetrablock base rubber polymer, 7wt% of EPOLENE C10 polyethylene wax, and 13wt% of the tackifier composition REGALREZTM1126 polymer blend. 与上面一样,在橡胶聚合物中的A和A'可以是含有苯乙烯结构部分的热塑性嵌段和B和B'可以是由聚(乙烯-丙烯)组成的弹性聚合物嵌段。 As above, in the rubber polymer A and A 'may be a thermoplastic block styrene moiety and B and B' may be made of poly - an elastic polymer block (ethylene-propylene) thereof.

这些各种组合物可以用于形成连续长丝和纺粘外面料。 These various compositions can be used to form continuous filaments and the outer spunbond fabrics.

在许多应用中,这一类型的复合材料适合于在仅仅一个方向例如纵向上拉伸和回复,据此平行提供了连续长丝,如附图中所示。 In many applications, this type of composite material suitable, for example the longitudinal direction stretch and recovery in only one direction, whereby the continuous filaments are provided in parallel, as shown in the accompanying drawings. 因此,复合材料的弹性组分不是各向同性的。 Thus, the elastic component of the composite material is not isotropic. 也就是说,弹性组分不必在每一方向上具有相同的拉伸和回复性能。 That is, the elastic component need not have the same stretch and recovery properties in every direction. 令人想望地,弹性组分将仅仅在褶裥无弹性材料允许复合材料拉伸的方向上具有所需的拉伸和回复性能。 Desirably, the elastic component of the pleats only in the inelastic material allows the composite material having the desired stretch in the direction of stretch and recovery properties. 例如,如果弹性材料的长丝,纤维和/或线条在仅仅一个方向上进行构型设计,则较少量的弹性材料可在该方向上用于提供某种水平的弹性特性,如张力,与如果弹性材料是各向同性的情况相比。 For example, if the elastic material of filaments, fibers and / or lines in only one direction configuration design, the relatively small amount of elastomeric material may be used to provide some level of spring characteristics in that direction, such as tension, and If the elastic material is isotropic compared to the case. 减少在复合材料中弹性材料的量会降低其成本,使得单次使用或有限使用产品例如一次性个人护理产品如尿布变得更有吸引力。 Reduction in the amount of the composite elastic material will reduce the cost, making the single-use or limited use products such as personal care products such as disposable diapers become more attractive.

现在回到图1,描绘了用于进行上述方法的示例性装置。 Returning now to Figure 1, depicts an exemplary apparatus for performing the above method. 如图1中所示,VFL系统11是垂直配置的。 As shown in Figure 1, VFL system 11 is vertically disposed. 安装挤出机15,从口模中向下挤出连续熔体长丝14以一定角度到达冷却定位辊12上。 Installation extruder 15, melt extruding continuous filaments from the die 14 downwardly at an angle reaches the upper registration roller 12 is cooled. 冷却定位辊12确保在通过系统的剩余部分中的正确定向排列,这是指当该系统展开该长丝时。 Cooling the registration roller 12 through the remaining portion of the system to ensure that in the correct orientation, this means that when the system is expanded when the filaments. 当该长丝在冷却定位辊12的表面上通过时,当它们向着第一冷却辊13的冷却表面运行时它们被冷却和固化。 When the filaments are positioned on the surface of the cooling roller 12 by, when they run toward the cooling surface of the first cooling roller 13 as they are cooled and solidified. 该长丝然后按照“S形”前进方式向下运行到第二辊16中和然后跨越第三辊17、第四辊18的表面和进入到由轧辊19和轧辊20构成的辊隙中。 The filament then follow the "S-shaped" forward run down to the second roller 16, and then a third roller 17 across the surface and into the nip roll by roll 19 and 20 constitute the fourth roll 18.

连续长丝可以在辊隙中与各种类型的面料相结合。 Continuous filaments may be combined in the nip with various types of fabric. 在描述于图1中的实施方案中,第一非编织纺粘面料22和第二非编织纺粘面料24在连续长丝的相对表面上相结合而形成粘结的层压材料25。 In the embodiment described in Figure 1, the first non-woven fabric 22 and the second spunbonded nonwoven spunbond fabric 24 on the opposite surface of the continuous filaments of the upper phase to form an adhesive bond laminate 25. 在一些实施方案中,可以使用仅仅一种面料,和在其它实施方案中可以将弹性连续长丝与三层,四层,或更多层的面料相结合。 In some embodiments, can use only one kind of fabric, and can be elastic continuous filaments with three, four, or more layers of fabric combination in other embodiments.

典型地通过使用喷射型粘合剂将面料粘结于连续长丝上。 Typically by using a spray type adhesive fabric bonded to the continuous filaments. 在辊隙中压缩和层压之前,喷射头23将粘合剂分配到非编织纺粘面料之中的至少一种面料(在图1中的第一纺粘面料22)的表面上。 Surface before the nip compression and laminating, adhesive spray head 23 will be assigned to at least one fabric (in FIG. 1 a first spunbond fabric 22) of non-woven spunbond fabric among the. 将粘合剂施加于另一个非编织纺粘面料上的第二喷射头可以用于一些实施方案中,尤其用于需要较大量的粘合剂的或存在较大的弹性线条的那些情况。 The adhesive is applied to the other non-woven spunbonded fabric may be used in a second ejecting head some embodiments, especially for those cases require greater flexibility than the lines or large amounts of binder. 在一些实施方案中,需要较大量的粘合剂将弹性材料锚固到非编织纺粘材料上。 In some embodiments, requires a relatively large amount of adhesive elastomeric material is anchored to the non-woven spunbond material. 在图1中所示的卷收辊21可以用于接收和卷绕所粘结的纺粘材料/连续长丝/纺粘材料层压材料25以便于储存。 21 spunbond material may be used for receiving and winding the adhesive in the volume shown in Figure 1 to close the roll / continuous filaments / spunbond laminate material 25 to facilitate convenient storage.

图2说明了包括支承框架26的VFL组装件的侧视图,在框架上固定了该系统的各种组件。 Figure 2 illustrates the assembly includes a support frame 26 of the VFL side view, is fixed on the frame of the various components of the system. 在所有附图中使用参考数字一致地表示在各种视图中的相同组件。 Using reference numerals in the drawings denote the same components consistently in various views. 正如首次在图2中所示,第一外部面料辊27和第二外部面料辊28为组装件提供所需面料22和24。 As first shown in Figure 2, a first outer fabric 27 and second outer fabric roll 28 roll assembly 22 and provide the desired fabric 24. 支柱29将轧辊20保持就位。 Strut 29 will roll 20 is held in place. 辊能够在将连续长丝向下输送到辊隙的侧视图中看出,其中长丝与面料相结合形成粘结层压材料。 Roll can be fed downward to the continuous filaments nip seen in side view, wherein the filament and fabric combined to form an adhesive laminate.

图4描绘了具有毛细管孔31的示例性挤出机口模头30。 Figure 4 depicts an exemplary extruder die with a capillary hole 31 of head 30. 在图5中,描绘了口模头的局部放大图32。 In Figure 5, depicts a partial enlarged view of the die head 32. 在挤出机口模头上的毛细管孔的图案和直径可以发生变化以提供具有合适间隔的长丝,但无需使用昂贵的梳子等等,以形成具有矫正弹性几何结构的织物。 Can occur in the extrusion die capillary hole machine head patterns and changes in diameter to provide a suitable spacing of the filaments, but without using expensive combs, etc., to form a fabric geometry having elasticity correction. 距离d1(在一排排的毛细管孔中心之间的距离),d2(在相对的排上的邻接对角线毛细管孔中心之间的距离)和d3(在同一排中的邻接毛细管孔中心之间的距离)可以发生变化,这取决于在最终产品中所需的具体特征。 Distance d1 (distance between the center of the rows of the capillary pores), d2 (in the adjacent row of opposing diagonal distance between the centers of the capillary pores) and d3 (in the same row are adjacent to the hole center of the capillary distance between) may vary, depending on the particular characteristics desired in the final product. 例如,在本方法中可以使用各种孔密度。 For example, the present method can be used in a variety of cell density. 在12-长丝/英寸实例中,在口模孔的中心线之间的距离(d1)可以是大约2.12毫米。 In 12- filaments / inch example, at a distance (d1) between the center line of the die orifice may be about 2.12 mm. 当使用18-长丝/英寸的孔密度时,在口模孔中心线之间的距离(d1)是大约1.41mm。 When using 18- filament / inch hole density, distance (d1) between the die orifice centerline is about 1.41mm.

图6说明了挤出机15的在相对于辊12的垂直轴有一定角度的位置上的侧视图。 Figure 6 illustrates a side view of the extruder with respect to the vertical axis 12 of the roll 15 of the angled position. 在图中显示的45角度已经发现是可以生产出可接受产品的并且允许连续长丝与辊12紧密配合以实现如上所述的断裂长丝的再穿线的一种角度。 45 angle shown in the drawing has been found possible to produce an acceptable product and allows continuous filament 12 in close cooperation with the roll angle to achieve a broken filaments as described above and then threading.

维持一定的辊速度,使得有合适的弹性拉伸程度在最终的层压材料中形成褶裥。 Rollers to maintain a certain speed so that there is a suitable degree of elasticity stretch the gathers formed in the final laminate. 定位冷却辊12正常地在约3-10英尺/分钟(“fpm”)的范围内的表面速度转动,而第一个垂直放置的冷却辊在大约5-约15fpm下转动。 Positioning the cooling roll 12 is normally about 3-10 feet / minute surface speed, the ("fpm") the range of rotation, and the first cooling roller is rotated vertically disposed at about 5 to about 15fpm. 下一个辊在大约7到约18fpm下转动,而最后的辊,当施涂和使用时,在约12-约100fpm的速度下转动。 Next roll at about 7 to about 18fpm under rotation, and the last roller, when applied and used, rotating at a speed of about 12 to about 100fpm. 这些范围是近似的,并且能够根据所需的条件和最终产物构型来变化。 These ranges are approximate, and can according to the desired conditions and to change the configuration of the final product.

在一个特殊的方法中,第一冷却辊在大约5fpm下转动;第二冷却辊在大约6fpm下转动;第三个未冷却辊在大约11fpm下转动;和第四个未冷却辊在大约26fpm下转动。 In a particular method, the first cooling roller is rotated at about 5fpm; second cooling roller is rotated at about 6fpm; and the third cooling roller at approximately 11fpm not under rotation; and a fourth cooling roller at approximately 26fpm not under rotation. 另一种方法使用10fpm的第一辊速度;20fpm的第二辊速度;40fpm的第三辊速度,和80fpm的第四辊速度。 Another method uses a first roll speed of 10fpm; 20fpm second roll speed; 40fpm third roll speed, and roll speed 80fpm fourth. 在这一方法中,轧辊的速度是大约75fpm。 In this method, the roll speed is about 75fpm. 在附加的方法中,第一冷却辊的速度可以是大约400fpm;后续辊的速度可以是大约750fpm以拉伸连续长丝;在轧辊中形成的复合材料的速度可以是大约1500fpm;和卷绕辊速度(允许纺粘面料的松弛和因此褶裥)可以是大约700fpm。 In an additional method, the first cooling roll speed may be about 400fpm; subsequent roll speed may be about 750fpm to stretching continuous filaments; speed roll formed in the composite material can be about 1500fpm; and winding roller speed (spunbond fabrics allow relaxation and therefore tuck) may be about 700fpm.

另外,在许多层压材料中,粘合剂组分以离散粘合剂线的形式施涂于无纺织物层的表面上。 Additionally, in many laminate, adhesive component in the form of discrete lines of adhesive applied to a surface of the nonwoven fabric layer. 粘合剂是以各种图案施涂以使粘合剂行列与弹性长丝行列交叉而形成各种类型的粘结网络,该网络包括粘合剂-与-弹性材料粘结或粘合剂-与-弹性材料粘结和粘合剂-与-粘合剂粘结两者。 Adhesive is applied to a variety of patterns and the adhesive ranks ranks elastic filaments formed by the intersection of various types of bond network, which comprises a pressure-sensitive adhesive - and - elastic material or adhesive bonding - and - elastic material and adhesive bonding - both adhesive bonding - and. 这些粘结网络可以包括较大总数量的粘合剂-与-弹性材料粘结和粘合剂-与-粘合剂粘结从而获得具有提高强度的层压制品,同时使用最低量的粘合剂。 These networks can include a large total adhesion amount of the adhesive - and - elastic material and adhesive bonding - and - adhesive bond to obtain a laminate having improved strength, while using a minimum amount of adhesive agent. 这一增强是通过粘合剂的铺设或喷雾图案的使用来实现,该图案是通过将粘合剂按照预定和特定的图案喷涂到无纺织物的表面上来形成的。 This enhancement is laying or by use of an adhesive spray pattern is achieved, the pattern is formed by an adhesive in accordance with a predetermined specific pattern and sprayed onto the surface of the nonwoven fabric is formed. 在大多数情况下,具有较少粘合剂的最终产物在不希望有的劲度上显示出下降,并且一般比具有更多粘合剂的产品更加柔性和柔软。 In most cases, the final product has a less adhesive in undesirable drop exhibited on some stiffness, and typically having more than adhesive products more flexible and soft.

按图案施涂该粘合剂以使粘合剂行列垂直或几乎垂直于弹性组分的方法已经发现是特别有利的。 The adhesive is applied in a pattern such that the adhesive line perpendicular or nearly perpendicular to the method of the elastomeric component has been found to be particularly advantageous. 真实的90粘结角在实践中是不可能的,但是高达50或60的平均粘结角一般在弹性线条和面料之间产生合适的粘结。 True 90 bond angles in practice is not possible, but up to 50 or 60 of the average bond angle generally between the lines and the elastic fabrics produced suitable bonding. 这些类型的粘结角的概念图解已显示在美国专利申请出版物No.US 2002/0104608的图12D和14中。 These types of bonding concept illustrated angle has been shown in U.S. Patent Application Publication No.US 2002/0104608 12D and FIG. 14. 形成粘合剂-与-弹性材料粘结,其中粘合剂和弹性线条的行列发生结合或交叉。 Form a binder - and - elastic material bonding, which ranks the adhesive and elastic binding or cross the lines occur.

连续粘合剂长丝-与-弹性线条交叉点也被控制到预定数量的交叉点/每单位的弹性线条长度。 Continuous adhesive filaments - and - elastic line intersection is also controlled to a predetermined length of the elastic line of intersection number / per unit. 通过在垂直取向中具有该粘合剂行列并且优化粘结的数量/每单位的弹性线条长度,能够在较低成本下以最低量的粘合剂和弹性体线条材料生产出最终的弹性线条层压材料以提供所需的产品特性。 By having the adhesive ranks in a vertical orientation and to optimize the number of bonded / elastic lines per unit length, it is possible at low cost and with a minimum amount of adhesive elastomeric material lines produce the final line of the elastic layer press material to provide the desired product characteristics.

各种粘结技术可以用于本发明中。 Various bonding techniques may be used in the present invention. 例如,粘合剂可以按照规定的行列而不是上述的熔体喷射来施涂。 For example, the binder may in accordance with the ranks not be applied above the melt blowing. 用于本发明中的示例性粘合剂行列纱布(scrim)图案已示于美国专利申请出版物No.US 2002/0104608的图13A中。 Used in the present invention are exemplary adhesive ranks gauze (scrim) pattern is shown in U.S. Patent Application Publication No.US 2002/0104608 FIG. 13A. 在这里使用的“纱布(scrim)”一般指一种材料的织物或无纺网幅,该材料可以是弹性或无弹性的,并且具有沿着在制造过程中的生产流程的通路的纵向(“MD”)取向线条组分和跨越织物的宽度的横向(“CD”)线条组分。 As used herein, "gauze (scrim)" generally refers to a woven or nonwoven material web, the material can be elastic or inelastic, and having along in the manufacturing process of the production process of a longitudinal passage (" MD ") oriented transversely across the fabric component and line width (" CD ") line components. 粘合剂行列图案能够施涂于层压材料上,其中在横向上有粘合剂行列的减少。 Ranks adhesive pattern can be applied to a laminate, wherein a decrease in the transverse adhesive ranks. 在图13中示出的纱布图案包括粘合剂行列136和弹性长丝130。 Shown in FIG. 13 comprises an adhesive gauze pattern ranks 136 and elastic filaments 130. 图13B说明了具有施涂于弹性线条130上的粘合剂行列139的另一个示例性纱布图案138。 Figure 13B illustrates another exemplary pattern having a gauze applied to the adhesive on the elastic string 130 139 138 ranks. 在这一实施方案中,已经看出粘结角是很高的,在粘合剂和弹性长丝之间的交叉处接近90。 In this embodiment, it has been seen that the adhesive is a high angle, the intersection between the adhesive and the elastic filaments close to 90 . 图13C说明了具有粘合剂行列142和连续弹性线条130的另一个纱布图案141。 Figure 13C illustrates another gauze patterns 142 and 141 have a continuous elastic adhesive lines 130 ranks.

交叉框,或横向,基重变化的控制可通过在外部面料的层压之前拉伸弹性线条来引起。 Control cross frame, or transverse, basis weight variation can be obtained by laminating the fabric prior to external lines to cause a tensile elastic. 在某些现有的方法中,弹性线条的基重可以在网幅的整个宽度上变化,因为当由于泊松效果该长丝被拉伸时该长丝倾向于迁移到边缘。 In some conventional methods, the base weight of the elastic line can be over the entire width of the web changes, due to the Poisson effect because when the filaments are stretched filaments tend to migrate to the edge. 在此情况下,当在x方向上拉伸时,材料倾向于在y和z方向上收缩。 In this case, when stretched in the x direction, the material tends to shrink in the y and z directions.

在某些实施方案中,该方法可以通过将拉伸线条的颈缩分布图和线条基重分布图相关联来防止该迁移。 In certain embodiments, the method may be stretched by the necking profile line and line-yl FIG associated redistribution to prevent the migration. 能够确定在交叉框基重中的所需偏移(shift),然后对挤出机口模进行调节以便与所需的偏移匹配。 Able to determine the required offset cross frame basis weight of (shift), the extruder die and then be adjusted to match the required offset and. 尤其,口模毛细管的长度可以进行调节,以控制单一长丝直径。 In particular, the length of the capillary die can be adjusted to control the diameter of a single filament. 在口模的边缘上的较长毛细管孔将得到具有减少基重的较薄长丝。 Long capillary pores on the edge of the die will be a reduced basis weight of thin filaments. 当该线条随后被拉伸和中间长丝迁移时,所生产的不均匀基重分布图将偏移到相对均匀的交叉框基重分布图。 When this line is then stretched and intermediate filament migration, the production base uneven weight distribution will be shifted to a relatively uniform cross-frame basis weight distribution. 这一均匀性允许更一致的辊构造和材料的外部狭缝的转化。 This uniformity allows more consistent configuration and material of the external roller slit conversion.

已经观察到,SILQUESTPA-1聚有机基硅氧烷加工助剂能够添加到KRATONTM弹性体组合物中以改进加工条件,同时保持用弹性体长丝形成的VFL层压材料的可接受的机械性能,即剥离强度。 It has been observed, SILQUESTPA-1 polyorganosiloxane KRATONTM processing aids can be added to the elastomeric composition to improve processing conditions, while maintaining an acceptable elastomer filaments formed laminate mechanical VFL properties, i.e., the peel strength. 通过SILQUESTPA-1聚有机基硅氧烷加工助剂的添加来显著减少对于在KRATONTM弹性体树脂的挤出过程中的压力和熔体破裂而言的通过量限制,更快的生产速率和更低的操作温度,例如多至50-100,都是可能的。 By SILQUESTPA-1 polyorganosiloxane processing aid added to significantly reduce the pressure in the extrusion process KRATONTM elastomer resin and melt fracture limit in terms of throughput, faster production rate and lower operating temperatures, e.g., up to 50-100, are possible. 理想地,SILQUESTPA-1聚有机基硅氧烷加工助剂添加到KRATONTM弹性体组合物中改进了加工,可以提供一种或多种下列益处:减少剪切作用,在通过量增加时延迟熔体破裂的开始,减少口模唇积垢,减少喷丝板堵塞,减少或消除在生产过程中的流淌扰乱,和一般增大特殊弹性体树脂和装置的加工窗口,例如通过降低挤出压力和/或温度。 Ideally, SILQUESTPA-1 polyorganosiloxane processing aid added to the KRATONTM elastomer composition improves processing, can provide one or more of the following benefits: reduce shearing, while increasing the amount of delay by Start melt fracture, reducing die lip build, reducing spinneret clogging, to reduce or eliminate in the production process of flowing disrupt, and generally increases the processing window elastomer resin and special devices, for example, by reducing the extrusion pressure and / or temperature. 这些益处也延长了口模和纺丝头组合件使用周期。 These benefits also extend the die head assembly and spinning cycle. 此外,SILQUESTPA-1聚有机基硅氧烷加工助剂的添加能够允许使用较少量的粘合剂。 Furthermore, SILQUESTPA-1 polyorganosiloxane processing aid added to allow use of smaller amounts of binder. 另外,在长丝挤出过程中的减少熔体破裂会提高从口模出来的所挤出弹性体长丝的稳定性和最大程度地减少长丝的重叠和长丝的弯折,从而改进长丝和包括该弹性体长丝的层压材料的加工。 Further, in the filaments during extrusion melt fracture reduction will improve the elastomeric filaments from the die out of the extrusion stability and to minimize overlapping filaments and filaments of bending, thereby improving the long including processing of the filaments and filaments of the elastomeric laminate.
