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 comprises a method for manufacturing the elastomeric composition of the present invention, the elastomeric filaments extruded laminate perpendicular to the filaments 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 system of vertical filament laminate 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 in various applications, such as in training pants women leotard and requires a certain degree of elasticity 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 laminating machine system through the use of vertically-oriented technology to produce 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。 More specifically, the process uses a number of root extrusion supply lines elastomeric continuous filaments, so that the component is formed from a stretchable elastomer 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 specific 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, and 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 continuous filaments join the first roller 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 This sheet extrusion line geometry for the melt extrusion deposition

到旋转辊或鼓上是理想的。 To a rotating roll or drum is ideal. 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 Or angular orientation of the filament angled at an angle from the die roll string out into the cut-off point provided the opportunity, resulting in improved spinning, more effective

能量转移,和一般更长的口模寿命。 Energy transfer, and generally 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 filaments from the die string out and follow a relatively straight trajectory contact roller surface at a tangent point. 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 outlet and a longitudinal axis (or horizontal axis of the first roll, which depending on the measured angle) between the angle may be 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 the extruder die and having a tip at the outlet side of the extruder to achieve over the downstream edge of the first roll. 另外,可以使用与垂直方向之间的角度如约20° ,约35° ,或约45° 。 In addition, the angle between the vertical direction can be used, such 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 explained below 12 - filament / inch spinneret hole density of 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 optimal angle with the extrudate exit velocity, roller speed, the vertical distance from the die roll to and from the die to roll on the horizontal centerline distance varies dead. 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。 Best performance can be achieved using a variety of geometries, resulting in improved efficiency and reduced spinning broken wire. 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.一般地,包括以上所述的(聚) 硅氣烷添加刑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) 硅氣烷添加刑的相同弹性体组合物相比。 In many cases, this can lead to potentially increase roll cover and lead to more efficient energy transfer and longer die life, attributed to the extrudate exiting the extruder die capillaries and travels to the cooling rolls pull the extrudate reduction and shear. In general, including the above (poly) alkoxy gas silicone elastomer composition add a penalty which the present invention has an improved spinning efficiency and reduce the broken wire, reducing the extrudate pull and shear, which means that does not include such a (poly) alkyl silicon gas added punishment compared to the same elastomeric composition.

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.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.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.例如,任何具体的辊可以在相当于 Causing the continuous filament continuous filament when carrying the roll positioning and operation in order to continuously flow through the filament vertically laminating system is stretched. When using a plurality of rollers, each successive roll in the direction of tightening reverse roll former, such lines may be continuous filaments from one roll to another roll off manually. In addition, the speed of each successive rollers may be different from the previous roll, to obtain the desired tensile and elongation rate characteristics. For example, in any particular roll may equivalent

任何在前辊的速度的l倍到IO倍之间和更高倍下操作.典型地,单独 Any front roller speed l to IO times between times and higher operating times. Typically, individual

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.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.另外,连续 The controller, servo motor or flip drive that can be used to control the speed of the rollers and drives each roller when the speed changes, one after another so that the rollers can rotate in a vertical line down the process at a faster rate stretching during exercise or stretch the line. In addition, continuous

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. Filament eventually reduced to about 0.008 to .040 inches in diameter fiber size, and sometimes reduced to about 0.015 to 0.020 inches in diameter.

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.例如,可以使用至少四个辊--笫一冷却(或定位)辊,第二冷却辊,笫三未冷却辊,和笫四未冷却辊.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. The number of individual rollers for continuous filaments fed to the bonding site may vary depending on the specific properties of the final product to change, for example, can be used at least four rolls - Zi cooled (or location) roll, a second cooling roll, a cooling roll is not Zi three, four and Zi uncooled rolls. Additionally, the continuous filaments in the system is supplied to the laminator requires only two portions before cooling roll in the laminator section nip the continuous filament spunbond fabric adhered to.

该辊可以进行等离子体涂教以提供良好的防粘性能.另外,该辊可以另外有紋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. 光滑辊可以用于一个或全部的辊.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.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増加均匀性. The rollers may be coated with a plasma taught to provide good release properties. Further, this roller may alternatively have a groove or channel in order to ensure continuous filaments extruded between the respective filaments to maintain proper separation distance, which is refers to when the filaments on the roll surface and flowing through the system can be used for a smooth roll or all of the roller case for the use of plasma-coated rolls, continuous filament not like them smooth, without that slides on roller coating. The plasma coating seize to increase in uniformity between the lines, and promoting continuous filament line distance.

各种机理可以用于槺冷连续长丝.例如,外界空气能够被加压通向纤维,以便控制该纤維的硬化.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. Kang various mechanisms may be used to cool continuous filaments. E.g., ambient air can be pressed towards the fiber, so as to control the fiber hardening. Additionally, a large roll can be used with sufficient surface area 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.这一片材的弹性低于连续长丝的弹性.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,或甚至机织纤維网幅.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.在一 Through a series of rollers and the stretched continuous filaments are then conveyed to a position so that the laminator section sheet may be bonded to the continuous filaments. Elasticity which is lower than the continuous sheet The elastic filaments. The sheet may be of various meltblowing nonwoven fabric web, a spunbonded nonwoven fabric web, carded web, or even woven fibrous web. However, some enhanced performance and production efficiency due to the polymer web of spunbonded nonwoven fabric used in a

的基重的聚丙烯纺粘面料. The basis weight of polypropylene spunbond fabrics.

粘结可以自生地实现或通过单独的粘合刑的使用或作为自生和粘合剂粘结的结合来实现.典型地,等连续长丝到达粘结站时该过程已经足够地樣冷该连续长丝,这样单独的自生粘合(或没有粘合刑的粘结) 是不可能的.典型地,使用粘合剂,如熔体喷射型粘合剂.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,則自生粘合是可能的. Bonding may realize from habitat or through a separate adhesive or as a combination of punishment and self adhesive bonding to achieve. Typically, etc. continuous filament reaches the bonding process has been enough to stop the kind of cold that continuous filament, such a separate self adhesive (or no adhesive bond punishment) is not possible. Typically, the use of an adhesive, such as a melt blown type adhesive. Although will be explained below, if the fabric or using a sufficient tackifying resin in a continuous filament, or other adhesive component, the self adhesive 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.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.另外,该粘合刑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.本发明不局限于任何具体的粘结机理. Adhesive can be sprayed directly bonded to the sheet on a continuous filament. However, other arrangements adhesive applicator such as brushing or the like can also be used. In addition, the adhesive sheet Penalty Before bonding the continuous filament may be applied directly to the sheet, it can be applied to the continuous filaments and the sheet before bonding, or may be applied to the filaments and the adhesive sheet while applying pressure on one or both. The present invention is not limited to any particular bonding mechanism.

可以使用的特殊熔体喷射型粘合刑包括Findley牌H2525A和Findley牌H2096,两者从Findley Adhesives(也已知为Bostik Findley) 获得.这些粘合刑可以通过热熔体喷射口模在大约300-375° F的升高 Special melt blown type adhesive punishment may be used include Findley Findley brand licensing H2525A and H2096, both from Findley Adhesives (also known as Bostik Findley) obtain these hot melt adhesive punishment by injection die at about 300 -375 ° F rise

温度下施涂到面料的内表面。 Temperature applied to the inner surface of the sheet. 熔体喷射粘合刑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.这些特殊的Findley粘合刑同样是弹性的. Melt adhesive spray punishment usually about 3 grams / weight per square meter ("gsm") of very light adhesive layer is formed on the final composite. These special Findley adhesive punishment is also resilient.

该系统使用夹辊以便对粘合刑涂层面料和连续长丝施加压力,导致必要的层压.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.典型的粘结压力可以是约50pli或约lOOpli. The system uses the nip rolls so that the bonding punishment coated fabrics and continuous long 丝施加 pressure, resulting laminate necessary external fabric and continuous filaments at a relatively high surface pressure bonded together, the pressure can vary from about 20 and 300 pounds / per inch ("pli") between typical bonding pressure may be about 50pli or about lOOpli.

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.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. Or laminator nip roll bonding (sometimes called a "laminator") section of the continuous filaments in the preliminary stretch. Bond or a nip roller with respect to the chill roll speed ratio can be varied, and in In most cases from about 2: 1 to 8: 1 and in some instances 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.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.网幅/线条片材将被拉伸和然后榆送到压延机辊味中以便利用粘合刑体系将面料粘结于片材上. 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. As an alternative, the elastic strips that are bonded to the polymer prior to drawing on web, so the line can be shipped in a single piece disposal. In this method, the thickening web of meltblown French may be applied to a group of parallel elastic filaments above. web / sheet lines will be drawn and sent to the calender rolls and elm taste punishment system in order to take advantage of the fabric adhesive bonded to the sheet. When used, this particular process Allow occasional broken wire or defects, but not to 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.再次,特殊的粘结机理和方法不受到本发明的教导的限制.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笫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 some cases, one or more additional fabric can be bonded to other continuous filaments drawn on the surface to obtain a separate stretchable article, wherein at least two continuous filaments sandwiched between the outer fabric Room. Again, a special bonding mechanism and methods are not limited by the teachings of the present invention. In many cases, only the spray adhesive applied to one surface of an external fabric, and then let carry binders fabrics and stretch the continuous filaments and in contact with the undertaking of two external fabrics will cause both - Fabrics / continuous filament laminate product has 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.该层压材料经由表面驱动巻取机被巻绕到巻收辊上.巻取机相对于粘结器 After the formation of the fabric bonded spunbond / elastomeric continuous filaments / spunbond laminates in a continuous filament, and then let the relaxation and contraction of the laminate to unstretched or low-stretched state. The laminate Volume material via the surface of the drive on the pick-up is Volume Volume received rolls around. Volume relative to the pick-bonder

的速度比导致拉伸连续长丝的松弛以及当层压材料巻绕到巻筒时导致层压材料收缩到褶裥状态.例如,该巻取机速度与粘结器辊速度之比 Faster than lead to relaxation and stretching continuous filaments around when laminates Volume Volume cylinder caused when the laminate to shrink pleated state. For example, the Volume pick-speed bonder roll speed ratio

可以是大约0,3比约1,0,并且可以是约0.5比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桐. May be about 0,3 to about 1,0 ratio, and may be about 0.5 to 1.0 continuous filaments cause contraction obtained pleats, stretchable laminate, wherein the outer fabric pleated between bond points Tong .

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.在一个特殊的实施方案中,该基重是在约2.85和约3.2 oz/yW之间• The entire base laminate weight can vary, but in some applications is about 2 and about 4 ounces / per square yard ("oz / yd2") between. In one particular embodiment, the basis weight is in • between about 2.85 and about 3.2 oz / yW

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. 例如,KRATONTM牌弹性聚合物可以榆入到挤出机中,在其中聚合物在约260和460。 Various types of compositions and various processing conditions can be used to form the elastic continuous filaments. For example, KRATONTM cards can elm elastic polymer into the extruder, in which the polymer is between about 260 and 460. F之间的控制温度下,和在某些情况在大约385° F 下熔化.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470。 By controlling the temperature between F, and melting at about 385 ° F in some cases. In other embodiments, the specific polymer depending on the melt temperature may be about 470. F到480。 F to 480. F.聚有机基硅氣烷的添加能够使挤出温度降低了50到100。 F. alkyl poly organosilicon gas added can reduce the extrusion temperature 50-100. F.聚合物然后在大约300到4000psi(典型地约1500 到约2000 psi)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.正如下面所解释,各种的口模孔构型 F. polymer then at about 300 to 4000psi (typically from about 1500 to about 2000 psi) pressure after a predetermined number of holes in the die extruded into a single continuous filament along a generally downward direction. As explained below, the various configurations of the die orifice

用于形成熔体喷涂粘合刑和/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.例如,当形成为纤維和/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.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. Melt adhesive coating for forming criminal and / or elastomer filament elastomeric material may have sufficient tack to allow or enhance autogenous bonding.

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 the outer fabric and spunbond continuous filaments.

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.因此, 复合材料的弹性组分不是各向同性的.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.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.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,則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.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. In many applications, this type of composite material suitable, for example the longitudinal stretch and recovery in only one direction, whereby to provide continuous parallel filaments, as shown in the drawings. Thus, the elastic component of the composite material is not isotropic. That is, the elastic component need not have the same stretch and recovery properties in each direction. desirably, the elastic component would just tuck inelastic material allows the tensile direction having the desired stretch and recovery properties. For example, if the elastic material filaments, fibers and / or lines in one direction only configuration design, the relatively small amount of elastic material can be used in the direction to provide a elastic characteristics species level, such as tension, and if the elastomeric material is isotropic compared to the case. In the composite material to reduce weight elastic material can reduce the cost, making single-use disposable or limited use products such as personal care products The diaper becomes more attractive.

交叉框,或橫向,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.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.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. Crossing control box, or transverse, basis weight variation can be caused by stretching the elastic line to the outside in the fabric before lamination. In some conventional methods, the elastic line of the base weight may vary across the width of the web because when due to the Poisson effect of the filaments are stretching the filaments tend to migrate to the edge. 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困和线条基重分布困相关联来防止该迁移.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.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.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.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困.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. In certain embodiments, the method may be stretched by distribution lines necking trapped and basis weight distribution lines to prevent the difficulties associated with the migration. Able to determine the required offset in the cross-block basis weight (shift), Then the extruder and die were adjusted to match the required offset. In particular, the length of the capillary die can be adjusted to control the single filament diameter. long capillary pores on the edge of the die will be having reduce the basis weight of thin filaments. When this line is then stretched and intermediate filament migration, the production of non-uniform basis weight distribution will be shifted to a relatively uniform cross-frame basis weight distribution difficulties. This uniformity allow more consistent roll configuration and material external slit conversion.
