Description

具有毛细吸收和耐压性能的薄型吸收件
                          技术领域
本发明涉及一种用于吸收体液，特别是月经和血液的吸收件。更具体地讲，本发明涉及一种具有吸收芯的薄型卫生巾，其厚度约小于5mm，吸收芯由至少3片吸收片组成，每片吸收片沿X和Y轴方向具有预定的毛细吸收能力。
                          背景技术
吸收件是指诸如尿布、卫生巾、训练裤、小便失禁垫巾、床上垫片、内裤衬里、腋下吸汗巾等产品。这些吸收件用于吸收体液，例如尿、月经、血液、汗水及其他人体排泄物。卫生巾、床上垫片和内裤衬里是妇女在排经前、排经期间和排经后使用的物品，用于吸收月经和其他排泄体液。卫生巾是外用物品，用粘接或机械固定方法固定在内裤上，紧靠在外生殖器附近体位。卫生巾在结构上显著区别于内裤衬里和内裤吸汗巾，卫生巾的尺寸一般较大，具有较确定的三维结构，较厚，外形较大。
由于卫生巾是用于经期主要排经时间，因此与内裤衬里或内裤吸汗巾相比，卫生巾设计成能够吸收较大量体液和能够佩戴较长时间。确切地讲，卫生巾应设计成可以处置中等和大量液体，总液体吸收容量一般约20～50克。
现今社会变化，妇女能够更多地参加各种体育活动。妇女衣着也引起相应变化，可以穿着紧身衣裤。目前卫生巾厚度均超过6mm，穿着紧身衣裤时，在外生殖器附近体位鼓起一个包。此外，妇女从事体育活动时，卫生巾的构型和尺寸有碍腿部运动和引起不适。鉴于上述情况，有必要开发一种薄型卫生巾，其厚度约小于5mm，且富有弹性，吸收液体数量与目前市售品相当。
开发厚度约小于5mm的薄型卫生巾时，我们发现这种薄型产品佩戴时有易卷曲倾向。妇女活动时，卫生巾在股间受挤压而导致弯曲变形。由于卫生巾卷曲而不能有效吸收从阴道排出的体液，部分体液侧流到内裤上。特别是大量排经期间，这种泄漏现象更为严重。因此，期望设计一种在X-Y平面上能够快速吸收体液并防止侧流的卫生巾，并且这种卫生巾能够抗卷曲。
                          发明内容
简言之，本发明是涉及一种厚度小于约5mm的吸收件。吸收件具有透液盖片、不透液挡片和置于盖片和挡片之间的吸收芯。吸收芯由至少3片平行叠置的吸收片组成。第一吸收片邻靠盖片，第三吸收片邻靠挡片。每个吸收片沿X和Y轴方向的吸收能力，按叠置顺序递增，即第一吸收片的吸收能力小于第二吸收片，第三吸收片的吸收能力大于第二吸收片。吸收片的吸收能力依次递增，有利于促进体液流离靠近体侧的盖片而进入吸收芯内部，从而充分地利用吸收芯。
本发明总的目的在于提供一种用于吸收体液，特别是月经和血液的吸收件。本发明的更具体目的是提供一种薄型卫生巾，这种卫生巾含有至少3片吸收能力递增的吸收片。
本发明另一个目的是提供一种佩戴时抗卷曲的薄型卫生巾。
本发明的其他目的及优点，对于熟知这一领域的技术人员来说，参照以下说明及附图，是显而易见的。

                          具体实施方式
一种能够吸收体液的吸收件(10)如图1所示。该吸收件可以是尿布、训练裤、卫生巾、内裤衬里、床上垫片、小便失禁垫巾、腋下吸汗巾，或者任何其他已知一次性吸收件，可以用于吸收尿、月经、血液、汗液或人体排出的其他体液。为了便于说明，吸收件(10)以卫生巾为例进行说明。对于熟知这一领域的技术人员来说，本发明公开的方法可用于制作任何一次性吸收件。
卫生巾(10)包括1片透液盖片(12)、1片不透液挡片(14)和1个夹置于盖片和挡片之间的吸收芯(16)。本发明侧重介绍液体吸收芯(16)、吸收材料和卫生巾(10)的耐压性能。吸收芯(16)由至少3片平行叠置的吸收片组成：第一吸收片(18)、第二吸收片(20)、第三吸收片(22)。以盖片(12)作参考点，第一吸收片(18)邻靠盖片(12)，第二吸收片(20)位于第一吸收片(18)下面，第三吸收片(22)邻靠挡片(14)。由盖片(12)至挡片(14)方向，吸收片(18、20、22)的毛细吸收能力依次递增。例如，第二吸收片(20)的毛细吸收能力大于第一吸收片(18)，第三吸收片(22)的毛细吸收能力分别大于第一(18)或第二(20)吸收片。这种结构可以充分利用吸收片(18、20、22)，即充分利用吸收芯(16)。
卫生巾(10)长度约150～320mm，宽度约60～120mm。卫生巾(10)具有田径运动场的跑道外形，两端呈园形，但是卫生巾的外形不是一个限制因素。卫生巾(10)厚度约小于5mm，优选的约小于4mm，并具有湿弹性约大于250克。
卫生巾(10)的盖片(12)接触佩戴者的身体，可透过液体。制作盖片(12)的材料是容易渗透体液的织物或无纺布，织物或无纺布可使用合成或天然材料。适宜的材料包括由聚酯、聚丙烯、聚乙烯、尼龙或其他热粘合性纤维制成的粘合绒面网片。其他聚烯烃如聚乙烯共聚物、聚丙烯共聚物和线型低密度聚乙烯，以及细孔膜片和网材料，也具有良好工作性能。优选的盖片材料是意大利Pantex S.R.L.公司生产的SULTEX PF10材料。盖片(12)也可用多孔热塑性膜片在其两侧衬贴无纺布制得。此种特殊设计使得盖片(12)接触佩戴者股部时具有柔软感觉，同时允许体液快速通过。
为了加速体液流进卫生巾(10)，可以在盖片(12)上开一系列孔(未绘出)。盖片(12)上开孔可以均匀或不规则分布，或者仅分布在沿卫生巾(10)纵向X轴的窄带区域内。开孔允许体液快速透进吸收芯(16)。开孔大小、形状和数目，可以根据使用者的特殊要求而变化。
挡片(14)垫衬在内裤裤裆的内表面上(未绘出)，挡片(14)一般不能透过液体。挡片(14)可设计成允许吸收芯(16)吸进液体时排出的空气或蒸汽通过。挡片(14)可使用具有上述性能的任何材料制作。良好材料是微压花聚合物膜片，例如聚乙烯或聚丙烯微压花膜片。优选使用聚乙烯微压花膜片，厚度0.0508-0.127mm(0.2～5.0密耳)，优选的约为0.0127-0.0762mm(0.5～3.0密耳)。盖片(12)和挡片(14)可共同延伸，并围绕吸收芯(16)周边形成面对面接触。可用粘合剂、超声波热封或任何其他方法，把盖片(12)和挡片(14)沿它们的周边密封起来。
吸收芯(16)由至少3片独立和性质不同的吸收片(18、20、22)组成，每片吸收片沿X和Y轴方向的毛细吸收能力依放置顺序递增。
在讨论吸收芯(16)的适宜结构时，可以把组件看作是放在平面上，挡片(14)位于吸收芯(16)下面，盖片(12)位于吸收芯(16)上面。吸收芯(16)可从其X、Y、Z轴3个方向进行说明。X轴沿卫生巾(10)长度方向；X轴与Y轴相互垂直，即Y轴沿卫生巾(10)宽度方向；Z轴与X-Y平面垂直，即Z轴沿卫生巾(10)深度即厚度方向。
第一吸收片(18)包含有聚丙烯和聚乙烯并排分布的双组分纤维，其形状可以与卫生巾(10)的形状相同，优选的第一吸收片(18)为长方形，长度等于或小于卫生巾(10)的总长度，宽度小于卫生巾(10)的宽度，长度约152～304mm，宽度约12～40mm，工作性能良好。优选的第一吸收片(18)的长度近似等于卫生巾(10)的长度，宽度约25.4～38.1mm，优选的约34mm。
第一吸收片(18)应采用能够将流至盖片(12)上的体液沿Z轴方向迅速转移的材料来制作。因为第一吸收片(18)小于卫生巾(10)，第一吸收片(18)的边缘距卫生巾(10)的纵向边缘有一定距离，因此体液被限制在第一吸收片(18)周边内的区域，然后体液向下渗透并被第二吸收片(20)吸收。此种设计使得体液被汇集在卫生巾(10)的中央区域，并把体液吸向下方，使得第二吸收片(20)能够更充分被利用。
沿Z轴方向具有高毛细吸收能力的材料可用于制作第一吸收片(18)，适宜材料是美国Kimberly-Clark公司生产的PRISM材料。PRISM材料详见美国专利US 5,336,552(发明人Strack等，受让人Kimberly-Clark公司)，作为参考在此引用该专利的制造部分。PRISM材料是无纺织物，制作这种无纺织物使用多组分聚合物纤维。第一和第二聚合物组分分布在沿纤维横截面显著不同的区域，并沿多组分纤维的长度方向连续延伸。制作无纺织物使用的纤维优选的是连续单丝，此种连续单丝可以采用纺粘工艺制得。沿多组分纤维的长度方向，第二聚合物组分至少构成多组分纤维外周表面的一部分。第二聚合物组分是聚烯烃和乙烯烷基丙烯酸酯共聚物的混合物。可通过热加工实现多组分纤维间的粘接。
更具体说，多组分纤维的第一聚合物组分约占20～80％(重量)，第二聚合物组分约占80～20％(重量)。优选的是，多组分纤维的第一聚合物组分约占40～60％(重量)，第二聚合物组分约占60～40％(重量)。
这里使用的“纤维”(Strand)一词是指把聚合物通过模孔所形成的拉伸挤出体。这种纤维包括短纤维和单丝。本发明制作无纺织物使用的材料可以是多组分短纤维，这种短纤维经梳理和粘合得到无纺织物。但优选的是，本发明使用的无纺织物是由连续性纺粘多组分单丝制得，多组分单丝被挤出经牵引铺展在运动中的成型面板上。
可以使用的无纺织物类型包括粉末粘合绒面网片、点对点压合网片、红外粘合绒面网片和空气流粘合绒面网片。红外粘合绒面网片和空气流粘合绒面网片可以任选地包括差别纤维的混合物，纤维长度约25-76mm(1.0～3.0英寸)，平均堆积密度约0.02～0.06g/cc。
第一吸收片(18)可以是无纺短纤维网片，它含有约75％至少6旦的聚酯纤维，例如Hoechst Celanese公司生产的PET(聚对苯二甲酸乙二醇酯)纤维。聚酯纤维长度约38-55mm(1.5～2.0英寸)；其余的25％纤维网片材料是不大于3旦双组分纤维，优选的是约1.5旦的双组分纤维。双组分纤维长度约38-55mm(1.5～2英寸)。适宜的双组分纤维是日本窒素公司生产的可润湿聚乙烯/聚丙烯双组分纤维。双组分纤维可以是皮-芯复合型纤维，芯体为聚丙烯，皮层为聚乙烯。聚酯纤维和双组分纤维一般均匀地掺混，而不是分层掺混。纤维通过热粘合，例如通过空气流粘合或红外粘合工艺得到绒面网片。
第二吸收片(20)位于第一吸收片(18)下面，沿X和Y轴方向的毛细吸收能力大于第一吸收片(18)。优选的是，第二吸收片(20)的毛细吸收能力至少是第一吸收片(18)的3倍。第二吸收片(20)的长度可约为152～304mm，优选的是等于卫生巾(10)的长度。第二吸收片(20)的宽度可以等于第一吸收片(18)的宽度，优选的较宽些。第二吸收片(20)可以约为50.8～76.2mm，最优选的约为63.5mm。
第二吸收片可以是一种亲水材料，该亲水材料由各种天然或合成纤维制得，包括纤维素纤维、表面活性剂处理的熔喷法非织造纤维、木浆纤维、再生纤维、棉纤维及其他纤维的混合纤维。优选是，第二吸收片(20)是美国专利US 4,100,324描述的一种材料，该材料通称为Coform。Coform是美国Kimberly-Clark公司生产的一种无纺织物材料。具有织物样外观，由以热塑性聚合物纤维和多种差别化木浆纤维经气流成型得到的基片制得。该热塑性聚合物纤维一般具有平均直径小于10微米，差别化木浆纤维分布在整个基片中起着把热塑性聚合物纤维相互隔离的作用。基片制作方法是，由混有熔喷法非织造微纤维的主空气流和混有木浆纤维的副空气流沿成型面板合并形成湍流混合气流，最后在成型面板上形成基片。Coform材料不仅具有织物样外观，同时较习用纤维素吸收材料具有较高弹性。
吸收芯(16)的第二吸收片(20)的基础重量一般大于其他吸收片。第二吸收片(20)的基础重量一般约为50～300g/m2，优选为100～200g/m2。最优选是，第二吸收片(20)的基础重量至少是第三吸收片(22)的基础重量的1.5倍。
第三吸收片(22)位于第二吸收片(20)和挡片(14)之间。第三吸收片(22)是一种湿稳定材料，特别对月经具有高吸收能力，可以使用微孔织物制作。优选是，第三吸收片(22)采用对月经具有良好吸收能力的熔喷非织造材料制作。美国专利US 4,798,603(发明人Meyer等，受让人Kimberly-Clark公司)介绍这种熔喷织造材料，作为参考在此引用该专利的制造部分。
第一吸收片(18)一般作为体液转移单元，允许体液沿Z轴被向下吸进卫生巾(10)内部，体液离开盖片(12)，使得佩戴者感到干爽舒适。第二吸收片(20)首先从第一吸收片(18)接受液体，然后沿其长度和宽度方向吸收液体，并将液体释放到第三吸收片(22)。第三吸收片(22)利用其较大的吸收能力沿其长度和宽度方向充分吸收液体。因此，只有当第三吸收片(22)达到完全饱和状态后，液体才进一步被第二吸收片(20)吸收。这种作用可为使用者提供良好的后用视觉信号，说明液体正在被吸收驻留在卫生巾(10)的底部，并且把传递给使用者的在用视觉信号加以强化。液体经第二吸收片(20)和第三吸收片(22)充分吸收，避免液体溢至卫生巾(10)边缘。这样可充分利用吸收芯(16)，并有助于减少侧流可能性。
图2是卫生巾(10′)的另一种结构。卫生巾(10′)使用的材料与图1所示卫生巾(10)相同，但是增加第四吸收片(24)。第二吸收片(20)采用“C”形折叠方式，具有两条并排相对的纵向边缘，两条边缘间有一段距离，最好是在两条边缘之间形成纵向缝槽。“C”形折叠方式使得第二吸收片(20)具有柔性，因此使得卫生巾(10′)能够紧密地接触佩戴者外生殖器附近体位。众所周知，如果吸收件能够稳定接触人体，就可以极大地减少侧漏可能性。缝槽还具有这样的优点，即它可以为液体提供一条直接流至第四吸收片(24)的路径，第四吸收片(24)放置在“C”形折叠的第二吸收片(20)内部。此条畅通途径对于月经体液特别有用，因为它可允许粘性液体从第一吸收片(18)畅通无阻地进入到第四吸收片(24)。具有一条能够使体液快速渗入到吸收芯(16)中心部位的通道，对于保持盖片(12)干爽和防止侧漏是十分有用的。第四吸收片(24)置于“C”形折叠的第二吸收片(20)内部，并且第四吸收片(24)的吸收能力大于第二吸收片(20)，但小于第三吸收片(22)。第三吸收片(22)与图1描述的吸收片相似。
第四吸收片(24)位于第二吸收片(20)和第三吸收片(22)之间，是由一层或一层以上非湿稳定材料组成，例如图3所示的单层纸片，或者由纸片自身折叠形成的有效多层吸收片。如图2所示，“E”形折叠的湿定型风干皱纹纸具有良好性能，且易于折叠制作。吸收纸片的基础重量可约为10～200g/m2，优选约为20～150g/m2，最优选约小于75g/m2。不管非折叠纸片的基础重量是多少，最好纸片的累积基础重量约小于400g/m2，特别是优选约小于200g/m2。例如，基础重量为100g/m2的纸片经折叠后具有累积基础重量200g/m2。
制造纸片的原料可以是硬木和/或软木纤维。纸片具有细孔结构，特别是对月经具有良好毛细吸收能力。第四吸收片(24)的宽度近似等于、小于或大于第一吸收片(18)的宽度。如果需要的话，第四吸收片(24)的宽度可以等于第二吸收片(20)的宽度。第四吸收片(24)的长度可以约为127～304mm。
试验发现，改进的吸收件结构有助于提高吸引片的利用率，以及有助于提高卫生巾(10、10′、10″)的耐压强度。耐压强度对于卫生巾(10、10′、10″)良好地贴合佩戴者的身体是至关重要的。本发明中吸收芯(16)的结构有助于吸收芯(16)在使用过程中抗卷曲。此外，吸收芯(16)具有良好“湿弹性”。按照下述测试方法，当卫生巾(10)灌注30ml蒸馏水并施加侧面压力250克时，由于具有“湿弹性”，卫生巾(10)将不会被压缩小于它的初始宽度的50％。
卫生巾(10)的测试装置(100)如图4所示。基座(106)平面尺寸为101.6mm×114.3mm，在基座(106)中央开有一个直径60mm的圆孔，基座(106)上垂直连接两块厚度为12.7mm光滑的LEXAN塑料板(102、104)。直立塑料平板(102、104)之间的缝槽宽度约为14.3mm。塑料平板(102、104)宽度约为120.65mm，从基座顶面计平板高度约73mm。测试装置(100)把卫生巾(10)维持在垂直状态。在卫生巾(10)吸收水分之前和之后，分别使用宽度约44.45mm，高度约50.8mm，厚度约12.7mm，重量为250克的黄铜块进行压缩试验。
以下是三种供测试的样品垫：1)Kimberly-Clark公司生产的市售品NEN FREEDOMUItraThin；2)原型A：具有Sultex材料盖片；40g/m2的PRISM材料转移层；吸收芯由100g/m2的coform材料按“C”形折叠方式把一块“E”形折叠的32g/m2纸片包裹其中，一片60g/m2熔喷法非织造物置于coform/纸片复合体下面；标准的0.0254mm(1密耳)厚聚乙烯挡片；3)原型B：具有Sultex材料盖片；40g/m2 PRISM材料转移层；吸收芯是由100g/m2 Coform按“C”形折叠方式把一块“E”形折叠的32g/m2纸片包裹其中，在该复合体下面放置两片32g/m2纸片；标准的0.0254mm(1密耳)厚聚乙烯挡片。
把测试样品垫从包装袋中取出，撕去保护纸，残留在垫上的粘合剂可用公知技术撒上滑石粉使之失却粘性。样品垫吸收水分之前，进行干压缩试验。黄铜块(108)的最大尺寸处于垂直方向，黄铜块(108)与卫生巾(10)中间部位的边缘接触而把铜块重量的压力施加在卫生巾(10)上。从测试装置(100)的基座(106)的上端面到黄铜块(108)的底部中点进行测量，即可活动干压缩数据。
湿压缩试验叙述如下。用30ml室温(约20℃)水灌注样品垫，然后静置5分钟。向样品垫注水速率为15ml/分钟。使用一台MasterflexConsole Drive泵进行供水，该泵为美国Cole-Parmer仪表公司的产品。采用Cole-Parmer仪表公司生产的#14 Tygon供水管。测试结果列于表1。

黄铜块(108)从样品卫生巾(10)移开5秒钟后进行湿弹性测量。
对各种吸收件，特别是卫生巾使用的各种材料进行了毛细吸收能力测定试验。使用一种染料溶液进行测试，染料溶液以3±0.5ml/30秒供液速率进行试验。在两个不同时间求取测量数据，即在发生初始污损30秒时，以及发生初始污损后5分钟，分别求取测量数据。测试设各及材料如下：
1、30秒钟可输送3±0.5ml液体的自动泵1台。Cole-Parmer仪表公司生产的Cole-Parmer-Masterflex泵工作性能良好；
2、1个刻度为10ml，容量1000ml Pyrex量筒；
3、高381mm(15英寸)的环形架1个；
4、针尖为3mm(1/8英寸)的针头固定在环形架上；
5、Cole-Parmer仪表公司生产的Masterflex Tygon#14供水管；
6、40ml染料溶液。该溶液由16.7克No.1蓝色染料加1000ml蒸馏水配制而得。No.1蓝色染料购自美国环球食品公司(Unirersal FoodCorporation)的Warner-Jenkinson分公司。
7、900ml蒸馏水
8、计时精确至0.1秒的表1个；
9、尺子1把
进行测定之前，把40ml染料溶液和900ml蒸馏水倒进容量为1000ml的Pyrex量筒中轻轻搅拌混合。
测试样品按以下方法进行预处理。首先，从包装袋中取出样品。然后将样品置于温度73°F±1°F，相对湿度50％±2％的环境下至少2h。经过预处理后，从每个样品的中央部位切割52mm×152mm(2×6英寸)样条。样条长度对应于被切割样品的长度。
样条测试步骤叙述如下。把52mm×152mm(2×6英寸)样条置于台面上，样条面朝上。针尖置于样条中央部位上方。打开供液阀门，染料溶液通过针尖到达样条中央部位。当染料溶液滴到样条时，马上开动秒表计时。到达30秒时，关闭供液阀门，同时停止秒表。此段时间代表所谓“初始污损”，供液3ml。快速将样条上盖片揭去，用尺子测量液体污渍的长度和宽度，为了测量液体污渍，小心剥离每片吸收片，使之与邻近吸收片分离。测量并记录每片吸收片上液体污渍的长度和宽度，测量结果即代表染料溶液对样条的初始污损。之后，全部吸收片和盖片放回原来位置，并开动秒表，5分钟后停表，将样条上盖片快速移开，再次按照上述方法测量并记录吸收片上液体污渍的长度和宽度。测量结果称为“污损后5分钟”读数。全部测量结果列于表2。
对本发明的四种原型垫进行了测试。原型垫分别标记为“1”、“2”、“3”、“4”，每种垫的结构详见以下说明。

由表2数据可见，除原型垫1外，初始污损5分钟后，熔喷法非织造物吸收片上液体污渍长度大于前一吸收片上的液体污渍长度。这种情况可用纸片置于coform内部加以解释。此种吸收片排布方式允许液体沿放置在coform内部的纸片快速转移，因此给出吸收材料不真实的相对毛细吸收速率。
列举几个实例对本发明进行了具体说明，所以对熟知此一领域的技术人员来说，显然很容易据此提出许多其他设计方案。因此，所有其他设计方案理应被本发明所涵盖，包括在本发明权项范围之内。
