技术领域
本发明涉及一种用于吸收性器物的复合材料和制造复合材料的方法。
背景技术
非织造材料通常用于吸收性器物例如尿布和妇女卫生巾。非织造材料经常用作这种吸收性器物的顶部片部件，在这种情况中期望实现柔软度，因为该顶部片与吸收性器物的穿用者皮肤接触。非织造材料的高蓬松度(loft):总厚度之比经常指示柔软度，因为该非织造材料是可压缩的，其又赋予包含该非织造材料的吸收性器物的穿用者以柔软感觉。虽然相对高蓬松度的非织造物当贴着皮肤使用时感觉柔软和凉爽，但是通常需要特定的加工来实现这样的特性，这会增加产品的成本。
通过插入和去除带倒钩的针来实现纤维缠绕是产生相对高蓬松度的非织造材料的一种已知方法，但是该方法相对缓慢和昂贵。用于产生高蓬松度的非织造材料的更快生产方法是用于松散纤维的水力缠绕的水刺(spunlacing)方法。水刺方法可以通过使用基本上为针的形状和直径的高压水射流来水力缠绕纤维，以制造触摸柔软和凉爽的相对高蓬松度的软非织造材料。
水刺是一种通过使纤维经受多行细高压水射流，来将松散纤维的纤网(web)缠绕到多孔带或移动穿孔或图案化筛上来形成片结构的方法。水刺方法使用非常细的高速水射流(基本上为针的直径)的阵列代替带倒钩的针，来缠绕纤维以获得纤网的完整性，同时获得相对高蓬松度的非织造材料。针状水射流通过高压集管来施加，压力可以是2000psi到高于8000psi。水针射流孔典型地直径为约0.005英寸，单个集管可以在一行中包含约30-约80个孔/英寸。3-8个集管可以放置于在加工方向上对齐的一行中，并且未缠绕纤维的纤网可以在加工方向上在穿孔带或筛状材料上移动。真空区存在于带下面来提取水。在纤维经水力缠绕成纤网之后，该纤网可以干燥和卷绕成卷，该卷然后可以在转化和用作吸收性器物中的层时展开。在发生蓬起(lofting)时水刺方法通常不会有助于生成与膜层的层合体，这是因为水射流的高压和针状形状会损坏该膜层，并且可能会从非织造层中除去该膜的大部分或全部。
纺粘非织造物的成本低于水刺非织造物，但是典型地具有小得多的蓬松度，而且经常不如其他非织造材料那样软。用于制造非织造纤网的纺粘方法是已知的。在所谓的Reicofil系统中，将聚合物粒料进料到挤出机中，挤出机将连续纤维通过具有多个小开口的模具挤出。聚合物离开模具时，纤维被细化或拉伸和冷却。然后通过集管或其他装置提供的空气流来将纤维纺成到随机的位置。在纤维纺成后，纤维无规布置在由开口筛材料制成的移动带上，来产生纺成纤维垫。可以施加吸力来确保缠绕的纤维在基本上水平取向上平坦放置，并且基本上钉在移动筛上。
然后可以将缠绕纤维的垫进料到压延机辊压区中，并且一个辊具有光滑表面和一个辊具有排成图案的凸点。可以将两个辊加热到高于纤维中聚合物熔点的温度。由于凸点将垫压向光滑辊，所以垫被压缩。施加到垫的热和压力产生了粘合点，其使纤维就位来产生纺粘非织造纤网。
非织造材料，无论是通过纺粘、气流铺置、梳理、水刺、水力缠绕或其他方法制造，都具有基重，其定义为在正方形区间(典型地计量为平方米)内包含于其中的纤维的质量(典型地计量为克)，以使得该基重计量为克/平方米(“gsm”)。另外，全部纤维具有被称为旦尼尔的厚度或直径。具有较重旦尼尔纤维和较少纤维的非织造材料的基重可能与具有较轻或较细旦尼尔的纤维和许多纤维的非织造材料相同。特征如蓬松度(厚度)，其是从非织造纤网顶部测量到非织造纤网底部的距离，对于给定质量的纤维可以通过选择纤维旦尼尔和产生蓬起的加工技术来操控，同时缠绕或粘合纤维纤网，以使得该纤网将具有拉伸强度和纤网完整性。遗憾地，该纺粘方法不会有助于生产较高蓬松度的非织造物，因为它具有水平纤维的倾向。
纺粘非织造物的性能可以通过改变纤维的旦尼尔和基重，以及改变用于制造纤维的聚合物来操控。一些聚合物较硬，例如聚酯，和一些聚合物更柔韧，例如聚丙烯和聚乙烯。最近才制造出足以被牵拉来制成纤维的聚乙烯聚合物。聚丙烯是用于纺粘非织造物的常用聚合物，纺粘聚丙烯非织造纤网典型地被称为“SBPP”。
还期望打算用于吸收性器物的顶部片中的非织造物中的纤维是亲水性的。天然纤维素纤维是亲水性的，历史上已经用于顶部片中。例如，Mizutani等人的美国专利6,548,731教导了相对短的亲水性纤维可以与较长的疏水性纤维交替散布来形成顶部片材料，并且可以使用疏水性合成纤维，只要用表面活性剂涂覆来使它们亲水。但是，表面活性剂当经受大量液体时通常将被洗掉，由此使合成纤维重新成为疏水性的。
虽然存在着合成的亲水性纤维例如人造丝、胶粘纤维、乙酸酯和纺成尼龙，但是这些聚合物类型通常相对刚性和坚硬，并且许多难以挤出成细纤维。所以，如果这样的材料用于顶部片的纤维中，则所形成顶部片将倾向于对吸收性器物的穿用者来说是粗糙的和不舒服的。
期望在吸收性器物中使用不太昂贵的纺粘非织造材料，并且仍然传递典型的水刺非织造材料的柔软度。

具体实施方式
现在将重点阐述本发明的不同实施方案。任何一个实施方案的讨论并不意在限制本发明的范围。相反，这些实施方案的方面意在强调本发明的广度，无论是否被权利要求书所涵盖。此外，这些实施方案现在已知或将来研发的任何和全部变型也意味着落入本发明的范围内。
术语表
在整个说明书中，术语“纤网”指的是能够卷绕成卷的材料。纤网可以是膜纤网、非织造纤网、层合纤网、有孔层合纤网等。纤网的面指的是它的二维表面之一，相对于它的边缘。术语“复合纤网”或“复合材料”指的是包含以面对面关系彼此接合的两个或更多个单独纤网的纤网。该接合可以通过组成纤网的边缘，不过该组成纤网彼此处于面对面的关系，或者该结合可以在跨过该组成纤网的特定点位置。
术语“膜”在本说明书中指的是如下来制造的纤网：将热塑性聚合物材料的熔融片材通过流延或吹胀挤塑方法挤出，然后冷却所述片材以形成实心聚合物纤网。膜可以是单层膜、共挤出膜、涂覆膜和复合膜。涂覆膜是包含单层膜或共挤出膜的膜，其随后用它粘结到的相同或不同材料的薄层来涂覆(例如挤出涂覆、印模涂覆、印刷等)。复合膜是包含多于一种膜的膜，其中至少两种膜以粘结方法组合在一起。粘结方法可以在膜层之间引入粘合剂层。
在整个本说明书中，表述“有孔膜”指的是存在从一个表面延伸到第二表面的多个孔的膜。二维有孔膜是孔洞中不存在三维结构的膜，该膜然后将平坦膜的第二表面连接到该膜的第一表面。“成形膜”是三维膜，其是具有凸起或延伸单元的膜，并且三维有孔膜是孔中存在三维结构(例如该孔的深度大于该膜的厚度)或者延伸单元具有通孔的膜。
术语“非织造纤网”表示包含多个纤维的纤网。这些纤维可以彼此粘结，或者可以是未粘结的。这些纤维可以是短纤维或连续纤维。这些纤维可以包含单一材料，或者可以包含多种材料，作为不同纤维的组合或者作为各自包含不同材料的类似纤维的组合。作为本文使用的，“非织造纤网”在它的一般含义下通常定义为大致平坦的结构，其是相对平坦、柔韧和多孔的，并且包括短纤维或连续细丝。非织造纤网可以是任何形成该非织造纤网的方法的产物，例如非织造纺粘和熔喷非织造纤网。非织造纤网可以包括纤网的复合或组合。在一个实施方案中，非织造纤网是由聚丙烯纤维制成的纺粘材料。但是，非织造纤网可以包含能用来制造纤维的任何聚合物材料。例如，非织造纤网可以包含聚乙烯、聚丙烯、弹性体、聚酯、人造丝、纤维素、尼龙的纤维以及这些聚合物纤维的共混物。包含不同聚合物的纤维也可以是共混的。
作为本文使用的，术语“筛”指的是三维模制设备，其包含用来在膜中形成延伸单元、凸起或孔的凹痕，或者在非织造纤网中形成凸起。在一个实施方案中，筛包含具有一定宽度和直径的管状元件。在可选的实施方案中，筛包含具有一定宽度和长度的带。横向是平行于筛宽度的方向。加工方向是平行于筛的旋转方向的方向，并且与横向垂直。
作为本文使用的，术语“延伸单元”指的是三维元件或凸起，其包含位于卷材的第一表面的平面中的有孔基础部分和大致在卷材的第二表面方向上延伸的侧壁部分。每个基础部分具有侧壁部分。侧壁部分终止于位于卷材的第二表面的平面中的“端部”或“顶点”。延伸单元的端部可以有孔或无孔。作为本文使用的，“有孔延伸单元”指的是在第二表面的平面中在其远端具有孔的延伸单元。在延伸单元的基础部分中的孔，也称为“主孔”，可以为多边形形状，例如正方形、六边形、五边形、椭圆、圆形、卵形或狭缝，排成规则或无规的图案。在一个实施方案中，孔可以为船形，如美国专利7,198,836中所述，其通过参考引入本文。突出的端部如果有孔的话被称为“次要孔”，可以为多边形形状，例如正方形、六边形、五边形、椭圆、圆形、卵形、狭缝或船形。
作为本文使用的，表述“吸收剂制品”和“吸收性器物”表示吸收和包含体液和其他身体分泌物的制品。更具体地，吸收剂制品/吸收性器物包括贴着或邻近穿用者的身体放置来吸收和包含从身体排出的不同分泌物的服装。
作为本文使用的，术语“弹性”用于描述在施加拉伸力时可伸长到优选其初始的未拉伸长度的至少2倍的拉伸长度的材料，并且其在释放伸长力时将回缩到其初始的未拉伸长度的至多1.75倍。
图1是基重约10gsm的纺粘非织造纤网10的一部分的顶视图。非织造纤网10包含多个纤维12，和通过纺粘方法产生的多个压缩粘合位置14，如上所述。
图2显示了图1的非织造纤网10的横截面。如所示的，当非织造纤网10置于大致水平表面上时，多个纤维12大致水平取向，即每个纤维位于大致水平的平面中，并且纤维12大致彼此平行。在图2中也可看到压缩粘合位14。纤维12是紧密填充的，所以其间总体上缺少竖直间隔。所示的非织造纤网10的平均蓬松度或厚度22是约0.010cm(0.0039英寸)。虽然显示了名义上10gsm的纺粘非织造纤网10，但是本发明的实施方案不限于此。作为本文使用的，术语“名义上”指的是近似值。例如，名义上10gsm的纺粘非织造纤网可以实际上具有至多约10.25gsm的平均基重。根据本发明的实施方案，可以使用具有低至名义上8gsm的基重的纺粘非织造纤网。
虽然可用于本发明实施方案的基重不存在上限，但是具有相对高基重(和更高成本)的纺粘非织造纤网也会具有更高的蓬松度，所以可能不期望用于本发明的实施方案。所示的实施方案并不意在以任何方式受限。本发明实施方案的一个方面开始于轻的、不昂贵的纺粘非织造纤网，并且使该纤网膨胀来模拟和起到类似于用其他方法例如上述水刺方法所制造的较高成本、蓬松度的非织造纤网的作用。
纤维12由聚合物制成，该聚合物可以是聚烯烃如聚丙烯。在一个实施方案中，非织造纤网10可以是SBPP，如上所述。在一个实施方案中，非织造纤网10可以用表面活性剂涂覆，以使纤维12在其外表面上是亲水性的。在一个实施方案中，表面活性剂可以以位于聚合物的无定形区域内的半粘性流体形式引入纤维12的聚合物中，以使纤维12是亲水的并保持亲水性，甚至在纤维12经历液体之后也是如此，如下面进一步详细讨论的。
图3显示了由根据本发明实施方案的图1和2所示的非织造纤网10液压成形和膨胀而成的液压成形的膨胀的纺粘非织造纤网30的一部分的横截面，如下所述。如所示的，初始纺粘非织造纤网10的许多纤维12已经膨胀到其间具有更大的竖直间隔，如箭头31所示。在非织造纤网10膨胀的过程中，一些纤维12会从它们初始的大致水平取向向上弯曲，而变成弯曲的纤维32。另外，一些之前是沿着非织造纤网10的长度连续的纤维12在膨胀过程中会断裂成变短的原纤维34，至少一些变短的原纤维34可以调整为更竖直对齐，并变成基本上竖直的原纤维36，如所示的。
液压成形的膨胀的纺粘非织造纤网30的平均膨胀蓬松度或厚度38是0.050cm(0.0197英寸)，其是初始纺粘非织造纤网10的初始蓬松度22的约5.0倍。本发明实施方案提供一种膨胀的纺粘非织造纤网，其蓬松度膨胀到初始纺粘非织造纤网蓬松度的至少约1.3倍，这足以增强柔软度，增强表面干燥，和增强包含液压成形的膨胀的纺粘非织造纤网30的吸收性器物的穿用者所感觉到的凉爽感。另外，与初始纺粘非织造纤网10的透气性相比，液压成形的膨胀的纺粘非织造纤网30的透气性可以增加至少约1.2倍，如下面进一步详细描述的。
图4是液压成形设备40的一个实施方案的示意性侧视图，液压成形设备40用于制造根据本发明实施方案的液压成形的膨胀的纺粘非织造纤网，例如上述的液压成形的膨胀的纺粘非织造纤网30和/或下述的液压成形的复合材料。具体地，图4的设备40提供一种液压成形的纺粘非织造纤网例如图1和2所示的纺粘非织造纤网10的方法，以膨胀它的蓬松度和产生液压成形的膨胀的纺粘非织造物，例如图3所示的液压成形的膨胀的纺粘非织造纤网30。
如图4所示，具有作为上述纺粘方法的结果的初始蓬松度的初始未膨胀的纺粘非织造纤网10的卷42可以以一定的取向和位置装在设备40的转轴43上，该取向和位置允许非织造纤网10从卷42展开并进一步加工。设备40包含成形结构44，其可以为可旋转成形筛的形式，并且非织造纤网10可以以连续运动在成形结构44上前进。在成形结构44是可旋转成形筛的实施方案中，非织造纤网10可以被移动，并且该筛可以以同步速度旋转过长的和窄宽度的真空狭缝区间45(其向含有该图的纸内延伸)。成形结构44可以具有多个孔44a，其目数是约3个孔/线性英寸(即“3目”)到约120个孔/线性英寸(即“120目”)。在一个实施方案中，目数可以是约25个孔/线性英寸(即“25目”)。
多个加压液体射流46布置在长的和窄宽度的区域(其向含有图4的纸内延伸)中，并且大致与成形结构44下方的长的和窄宽度的真空狭缝区间45对齐。液体射流46经配置来在非织造纤网10经过真空狭缝区间45时，在纤网10的外表面上以约200psi-约800psi的压力提供液体47例如水的重叠流。在一个实施方案中，液体射流46中的液体的压力可以是约400psi-约800psi。液体流47的压力足以推动和将纺粘纤维12的大部分从紧密填充的水平取向(图2所示)调整为更大的竖直间隔(图3所示)。
纺粘非织造物10的许多纤维可以被推动向上弯曲，并且至少一些原来连续的纤维会断裂成变短的原纤维，如图3所示。初始纺粘非织造纤网10的这种断裂使膨胀的纺粘非织造纤网30的膨胀的蓬松度是初始纺粘非织造纤网10的蓬松度的至少约1.3倍，和增加的透气性是该初始纺粘布的透气性的至少约1.2倍。另外，液体射流46的压力足以将非织造纤网10的一部分推入成形结构44中的多个孔44a中并形成从膨胀的非织造纤网的一个表面延伸的多个凸起，如下面进一步详细描述的。
图5显示了根据本发明实施方案的单个液体射流46，其可以用于图4的设备40中。如所示的，液体射流46包含喷嘴54，其经配置来喷射横截面为扇形的液体流47(例如水)。液体流47大致形状是细长椭圆，具有宽度‘w’和长度‘l’。离开单个喷嘴54的液体流47可以具有长宽比(l/w)约3∶1-约10∶1的细长椭圆形状。在一个实施方案中，液体流47的细长椭圆形状的长宽比可以是约7∶1，并且在冲击非织造纤网10的位置处，测量长度是约1.75英寸和测量宽度是约0.25英寸。
多个液体射流46进一步详细显示在图6中。如所示的，单个喷嘴54经对齐并附接到入口62处供有加压液体的集管60。在一个实施方案中，单个喷嘴沿着集管60间隔约每1-2英寸。在一个实施方案中，单个喷嘴沿着集管间隔约每1.5英寸。液体流47每个在它们各自的边缘56处与相邻的流稍微重叠。多个液体流47一起产生由单个喷嘴54形成的加压液体68长的和窄宽度的区域，每个单个喷嘴54使液体成形为各自的图5所示的细长椭圆。液体流47的边缘56重叠，以使得加压液体可以跨过纺粘非织造纤网10的整个长度提供到纺粘非织造纤网10，同时保持窄宽度(图5中的‘w’)，甚至作为一个整体。
再来看图4，真空狭缝区间45可以具有足够的吸力来从纺粘非织造纤网的表面除去任何残留的液体，这些液体会降低液体流47冲击纺粘非织造纤网10的力量。然后可以将膨胀的纺粘非织造纤网30随后在一个或多个干燥器48中干燥，并用至少一个切开刀片49切割到优选的宽度。可以通过卷绕机50将膨胀的纺粘非织造纤网30卷绕成至少一个卷52。在一个实施方案中，膨胀的纺粘非织造纤网30也可以用表面活性剂涂覆或者以其他方式处理，以进一步增强膨胀的纺粘非织造纤网30的性能。
如上所述，在一个实施方案中，纤维12可以包含表面活性剂，其会经时迁移到纤维的外表面。不受理论束缚，施加到纤维的聚合物的内部结构内的表面活性剂流体的压力与纤维外部的环境大气压力之间的压力差将引起表面活性剂朝着纤维的外表面迁移，直到实现平衡。可以想到，当实现平衡条件时，仅少量的引入聚合物中的表面活性剂迁移到该表面。如果表面活性剂被上述初始液压成形方法或者被使用者穿用时的液体排泄物从纤维的表面洗掉，则将失去平衡，并且更多的表面活性剂将朝着纤维的外表面迁移来实现新的平衡。可以根据在液压成形方法过程中以及纤维将引入到的吸收性器物使用过程中预期的损失量来确定引入纤维的表面活性剂的量。如果将表面活性剂引入纤维中的液压成形的膨胀的非织造纤网30用作例如吸收性器物中的顶部片或拦截分配层(“ADL”)，则顶部片的功能性流体拦截速率值可以持续进行，甚至在吸收性器物超过它的流体容纳能力之后也是如此。
图7A和7B是在液压成形设备例如图4的设备40上生产的液压成形的膨胀的纺粘非织造纤网70的一部分的侧视图。液压成形的膨胀的纺粘非织造纤网70由名义上基重10gsm和平均蓬松度或厚度约0.0040英寸(约102微米)的初始纺粘非织造纤网来生产，其用Ames412.5厚度量规使用4.8盎司重量来测量。图7A显示了液压成形的膨胀的纺粘非织造纤网70第一侧的第一表面72，其经受了液压成形设备40的液体射流46，图7B显示了液压成形的膨胀的纺粘非织造纤网70第二侧的第二表面74，其与第一表面72相对并与液压成形设备40的成形结构44接触。如所示的，第一表面72基本上平坦，而第二表面74具有从中延伸的凸起76的图案。凸起76的图案与成形结构44中的孔44a的图案基本相同，其目数是约25个单元/线性英寸(即25目)。液压成形的膨胀的纺粘非织造纤网70的平均蓬松度或厚度是约0.0076英寸(约193微米)，其用Ames 412.5厚度量规使用4.8盎司重量来测量，或者是初始未膨胀的纺粘非织造纤网的蓬松度是约1.9倍(增加90％)。
图8显示了包含膨胀的纺粘非织造层82和聚合物膜层84的液压成形的复合材料80的一部分的横截面。膜层84包含多个延伸单元86，其延伸远离膨胀的纺粘非织造层82。在所示的实施方案中，膜层84的延伸单元86每个在它们各自的顶点87开孔，并且延伸单元86是目数约25个单元/线性英寸(即“25目”)的大延伸单元，这与成形结构44的孔44a的目数基本上相同。大延伸单元具有包含液压成形的复合材料的聚合物膜层的连续细化部分的侧壁，该连续细化部分延伸远离复合前体材料的初始平面(如下所述)，并且多个延伸单元每个通过界区85与相邻的延伸单元隔开，界区85具有包含液压成形的复合材料的未被干扰的基本上平坦表面的宽度。聚合物膜层的延伸单元的至少一个可以在其远端具有孔。在液压成形的复合材料80中，膨胀的纺粘非织造层82的纤维和原纤维的部分已经被推入膜层84的延伸单元86中，并且一些原纤维88延伸穿过该孔并超过包含膜层84的延伸单元86的顶点87的平面。
可以通过不同的方法来制造经历液压成形方法的复合前体材料，例如如图9-11所示。在图9所示的设备90中，初始未膨胀的非织造纤网10的卷42可以置于转轴91上，聚合物膜94的卷92可以置于独立的转轴93上。聚合物膜94的聚合物可以包括一种或多种聚烯烃，包括但不限于聚乙烯、超低密度聚乙烯、聚丙烯、乙烯-乙酸乙烯酯、茂金属、线性低密度和线性中密度聚乙烯，以及其他聚合物，包括但不限于弹性体聚合物，包括但不限于基于聚丙烯的弹性体、基于乙烯的弹性体、基于共聚多酯的弹性体、烯烃嵌段共聚物、苯乙烯嵌段共聚物等，或者其组合。聚合物膜94可以是实心聚合物膜，或者可以是有孔的。在一个实施方案中，聚合物膜94可以具有微单元或微孔的图案，其使用真空成形、液压成形、机械成孔和/或压纹方法来产生。
初始未膨胀的非织造纤网10和聚合物膜94每个可以进料到两个压延机辊96、97之间的压区95中，其至少一个可以加热到允许非织造纤网10和/或聚合物膜94软化的温度。在一个实施方案中，压延机辊96、97的至少一个可以在其表面上具有三维图案，以使得聚合物膜94和非织造纤网10经历点粘结法，如本领域已知的。在压区95中施加到非织造纤网10和聚合物膜94的压力使得非织造纤网10和聚合物膜94彼此粘合以制造复合前体材料98，然后在包含非织造纤网10和聚合物膜94的复合前体材料98经过成形结构44时经受液体射流46。液体射流46、成形结构44和真空狭缝45的组合制造包含膨胀的纺粘非织造层和聚合物膜层的液压成形的复合材料99，该聚合物膜层具有对应于成形结构中孔44a的图案而排成图案的延伸单元，如上面涉及图8所示的实施方案所述。例如，如果成形结构44的目数是约40个孔/线性英寸(即“40目”)-约120个孔/线性英寸(即“120目”)，则液压成形的膜单元将是目数约40目-约120目的延伸的微单元。如果成形结构的目数小于约40目，则液压成形的膜单元将是目数小于约40目的延伸的大延伸单元。
在经过干燥器48之后，可以将液压成形的复合材料98切开并用卷绕机50卷绕成卷99a。在一个实施方案中，至少液压成形的复合材料99的膨胀的纺粘非织造层还可以用表面活性剂涂覆或者以其他方式处理，以进一步增强液压成形的复合材料99的性能。在一个实施方案中，液压成形的复合材料99的纤维可以已经包含表面活性剂，如上所述。
在一个实施方案中，位于液体射流46和成形结构44上游的设备90的部件可以离线布置来形成复合前体材料98，并且复合前体材料的卷可以置于图4的设备40的转轴43上，并且如上所述进行加工。
图10显示了设备100的一个实施方案，其经配置来如下制造层合的复合前体材料101：在初始未膨胀的纺粘非织造纤网10经过压区104时，在由金属辊105和橡胶辊106产生的压区104将熔融聚合物层102从膜挤出模具103直接挤出到初始未膨胀的纺粘非织造纤网10上。熔融聚合物层102可以包含一种或多种聚烯烃，包括但不限于聚乙烯、超低密度聚乙烯、聚丙烯、乙烯-乙酸乙烯酯、茂金属、线性低密度和线性中密度聚乙烯，以及其他聚合物，包括但不限于弹性体聚合物，包括但不限于基于聚丙烯的弹性体、基于乙烯的弹性体、基于共聚多酯的弹性体、烯烃嵌段共聚物、苯乙烯嵌段共聚物等，或者其组合。
传送辊107可以用于将层合的复合前体材料101重新取向，以使得层合的复合前体材料101的聚合物膜层接触成形结构44，并且液体射流46将液体流47直接提供到初始纺粘非织造纤网10上。应当理解，设备100中可以使用另外的辊，并且所示的实施方案并不意在以任何方式受限。液体射流46、成形结构44和真空狭缝45的组合制造包含膨胀的纺粘非织造层和聚合物膜层的液压成形的复合材料108，该聚合物膜层具有对应于成形结构44中孔44a的图案而排成图案的延伸单元，如上所述。
在图10所示的实施方案中，使用传送辊109来将液压成形的复合材料108与干燥机48对齐，并且在经过干燥机48之后，可以将液压成形的复合材料108切开并用卷绕机50卷绕成卷108a。在一个实施方案中，至少液压成形的复合材料108的膨胀的纺粘非织造层还可以用表面活性剂涂覆或者以其他方式处理，以进一步增强液压成形的复合材料108的性能。在一个实施方案中，液压成形的复合材料108的纤维可以已经包含表面活性剂，如上所述。
应当理解，可以使用另外的辊来传送液压成形的复合材料108，并且所示的实施方案并不意在以任何方式受限。在一个实施方案中，位于液体射流46和成形结构44上游的设备100的部件可以离线布置来形成层合的复合前体材料101，并且层合的复合前体材料的卷可以置于图4的设备40的转轴43上，并且如上所述来液压成形。
图11显示了设备110的一个实施方案，其经配置来如下制造层合的复合前体材料112：在初始未膨胀的纺粘非织造纤网10以同步速度移过第二成形结构114时，将熔融聚合物层102从膜挤出模具103直接挤出到初始未膨胀的纺粘非织造纤网10上，以使得在熔融聚合物102接触非织造纤网10时，纺粘非织造纤网10经过第二真空狭缝区间115。第二成形结构114的孔的图案经配置来允许在第二真空狭缝区间115中产生真空，以将纺粘非织造纤网10靠着成形结构114牵拉，并且由于纺粘非织造纤网10的渗透性，聚合物膜层将在聚合物冷却时贴合非织造纤网10。可以使用传送辊116、117来为聚合物层提供进一步的冷却和/或将层合的复合前体材料112重新取向，以使得层合的复合前体材料112的聚合物膜层接触成形结构44，并且液体射流46将液体流47直接提供到初始纺粘非织造纤网10上。应当理解，可以使用另外的辊来传送复合前体材料112，并且所示的实施方案并不意在以任何方式受限。液体射流46、成形结构44和真空狭缝45的组合制造包含膨胀的纺粘非织造层和聚合物膜层的液压成形的复合材料118，该聚合物膜层具有对应于成形结构的孔44a的图案而排成图案的延伸单元，如上所述。
在图11所示的实施方案中，使用另外的传送辊119来将液压成形的复合材料118与干燥机48对齐，在经过干燥机48之后，可以将液压成形的复合材料118切开并用卷绕机50卷绕成卷118a。在一个实施方案中，至少液压成形的复合材料118的膨胀的纺粘非织造层也可以用表面活性剂涂覆或者以其他方式处理，以进一步增强液压成形的复合材料118的性能。在一个实施方案中，液压成形的复合材料118的纤维可以已经包含表面活性剂，如上所述。
应当理解，可以使用另外的辊来传送液压成形的复合材料118，并且所示的实施方案并不意在以任何方式受限。在一个实施方案中，位于液体射流46和成形结构44上游的设备110的部件可以离线布置来形成层合的复合前体材料112，并且层合的复合前体材料112的卷可以置于图4的设备40的转轴43上，并且如上所述来液压成形。
可以使用其他常规方法来制造复合前体材料，并且本文所述的方法不应当被认为以任何方式受限。例如，在一个实施方案中，可以使用粘合剂材料来将聚合物膜和初始未膨胀的纺粘非织造纤网粘结在一起。在一个实施方案中，可以使用超声波粘合装置来在聚合物膜和初始未膨胀的纺粘非织造纤网之间产生粘结。
使用热粘合方法(其包括将熔融聚合物层直接挤出到纺粘非织造纤网上，如上面涉及图10和11所述)来制造层合的复合前体材料的一个潜在优点是，所形成聚合物膜层会比使用已经形成的聚合物膜的方法更薄。例如，直接挤出方法可以允许产生名义上基重约8-12gsm的非常薄的聚合物膜。
然后可以将具有凸起的液压成形的膨胀的纺粘非织造材料或具有延伸单元(有或没有孔)的液压成形的复合材料二次经过使用图4的液压成形设备40(包含具有小于约40个孔/线性英寸的不同目数的不同的成形结构44)的液压成形方法，以便能够产生大凸起或延伸单元(有或没有孔)的图案。大延伸单元可以具有包含液压成形的复合材料的连续细化部分的侧壁，该连续细化部分延伸远离液压成形的复合材料的初始平面。在一个实施方案中，可以使用图4的液压成形设备40来通过对液压成形的复合材料压纹且不产生孔而产生更大的三维表面。
在一个实施方案中，可以分别在液压成形的膨胀的纺粘非织造材料或已经具有凸起或微延伸单元的液压成形的复合材料中经由以下方法来产生大延伸单元的图案：通过使材料经过经配置来形成大尺寸孔的设备例如图12所示的设备120来为该材料机械穿孔。如所示的，设备120包含具有销124的图案的销辊123，和具有经配置来容纳销124的腔室126的匹配图案的配对辊125。销辊123和配对辊125可以以相反方向旋转来形成压区127，可以将液压成形的复合材料128经过压区127进料。销124从销辊123的表面凸起，并且腔室126凹进配对辊125的表面内。销辊123和配对辊125可以对齐，以使得销124与腔室126匹配，从而在辊123、125旋转时，销124在压区127插入腔室126中，辊123、125之间的液压成形的复合材料128被销124穿孔，由此形成有孔大延伸单元的图案。
所形成材料包含有孔的微延伸单元(或凸起)和大延伸单元，并且可以卷绕成卷129，用于后续转化成吸收性器物中的顶部片或其他层例如ADL。大延伸单元的目数可以小于约40个单元/线性英寸(即“40目”)。大延伸单元可以延伸远离液压成形的复合材料的初始平面，由界区隔开，该界区每个具有一定宽度并且包含具有微延伸单元的液压成形的复合材料的平面。这种机械穿孔方法更详细地描述在共同转让给Cree等人的美国专利7,204,907中，其整个内容通过参考引入本文。
在一个实施方案中，可以使用图13所示的设备130，在液压成形的膨胀的非织造纤网和/或液压成形的复合材料中形成大凸起或大延伸单元的图案。如所示的，图12的设备120的销辊123和配对辊125被匹配的压纹辊132、134替换，从而可以在如图13中的131所示的液压成形的膨胀的纺粘非织造材料或液压成形的复合材料上产生三维表面(无孔)。在材料131经过压纹辊132、134之间后，该材料可以卷绕成卷136，用于进一步加工。
图14提供了例如图8所示的液压成形的复合材料的一部分的图示的横截面图。提供这个图示来明确经组合来形成本发明的不同结构。
图14显示了膨胀的纺粘非织造层82和聚合物膜层84，其一起形成复合材料80。膜层84包含延伸远离膨胀的纺粘非织造层82的多个延伸单元86。图14显示了延伸单元86中的一个。
应当是明确的，图14还显示了与延伸单元86套合(register with)形成的凸起76。如上所述，可以想到，凸起76和延伸单元86经由液压成形方法形成。但是，从前述内容还明确的是，也可以使用液压成形之外的方法而不脱离本发明的范围。
可以想到，延伸单元86是包含在复合材料80中的全部延伸单元86的代表，不过可以想到并非全部延伸单元86包含纤维和/或原纤维88。具体地，可以想到，延伸单元86的一个或多个可以不包含纤维或原纤维88。可以想到，一个或多个延伸单元86中不存在纤维或原纤维88也落入本发明的范围内。
为便于后面的讨论，标记了膜层84的第一表面84a和第二表面84b。
在所示的实施方案中，延伸单元86在第二表面84b的方向上延伸远离非织造层82。延伸单元86在图中用虚线圆来表示。
延伸单元86涵盖至少膜层84形成侧壁83的部分。如所示的，延伸单元86限定了三维孔AP，其从膜层84在界区85的部分延伸到顶点87。如上所述，可以预期，延伸单元86的侧壁83从膜层84与界区85相邻的部分向顶点87变细。还应注意，纤维和/或原纤维88的一些穿过界区85所定义的平面延伸到孔AP中，甚至超过包含膜层84的延伸单元86的顶点87的平面。换言之，从本发明的讨论中明确的是，纤维或原纤维88延伸到延伸单元86的一个或多个中，以使得纤维88处于具有非织造纤网82的平面之外。由此，纤维和原纤维88形成了本文所定义的凸起76。
延伸单元86所限定的孔AP显示为在第二表面84b的方向上延伸远离膜层84的界区85的“锥体”或“火山”。因此，孔AP限定了与界区85的平面一致的第一孔AP1(近孔)，和由顶点87限定的第二孔AP2(远孔)。不限制本发明，孔AP可以具有任何所需或所期望的形状。例如，孔AP可以具有所示的圆锥形状，其中侧壁83经布置以使第一孔AP1限定的面积大于第二孔AP2的面积。另外，孔AP可以具有圆柱形状。如果如此，可以想到，侧壁83基本上垂直于界区85限定的平面。这里，可以想到，第一孔AP1和第二孔AP2的面积相等或基本上相等。在又一实施方案中，孔AP可以具有端部张开的横截面或漏斗形状，其中侧壁83向外延伸以使第一孔AP1限定的面积小于第二孔AP2的面积。
如图14所示，延伸穿过孔AP的纤维88的一些延伸穿过第一孔AP1而未穿过第二孔AP2。那些纤维或原纤维88裹在孔AP内。其他的纤维或原纤维88延伸穿过第一孔AP1和第二孔AP2二者，由此整体延伸穿过孔AP。
在任何上述用于将大延伸单元(有或没有孔)整合到具有微延伸单元的液压成形的复合材料的方法中，如果该液压成形的复合材料与向下取向的非织造层一起引入该方法，则该微延伸单元将向上取向和该大延伸单元将向下取向。相反，如果该液压成形的复合材料与向上取向的非织造层一起引入，则该微延伸单元将向下取向和该大延伸单元也将向下取向。在一个实施方案中，具有目数小于约40个单元/线性英寸的大延伸单元的液压成形的复合材料可以通过上述方法之一进一步加工，以增加大延伸单元的第二图案，不过对于界区宽度来说期望较小的微延伸单元，因为该微延伸单元可以提供增强的柔软度和/或提供毛细管吸力来用于增强表面干燥。微延伸单元(有或没有孔)和大延伸单元(有或没有孔)的不同组合，包括这些延伸单元的取向，可以根据本发明的实施方案来产生。例如，使用上述的设备，可以通过改变成形结构44的目图案来改变延伸单元的尺寸，并且可以通过改变要进料到成形结构的复合前体材料的取向和/或将液压成形的复合材料进料到进行另外加工的设备，来改变该延伸单元的取向。
实施例1
使用根据本发明实施方案的方法，在多种成形筛上加工基重10.25gsm(名义上10gsm)的纺粘非织造纤网，这些成形筛具有大于40个孔/线性英寸的目数以及小于40个孔/线性英寸的目数。当通过放大光学装置(其包括Navitar视频成像显微镜，具有Image-Pro图像分析软件)在横截面中测量时，该纺粘非织造物从顶部表面到底部表面的初始蓬松度平均为约0.012cm。在一个实施方案中，该放大光学装置可以包括扫描电镜(“SEM”)。将样品每个切成约1.0英寸(2.54cm)宽的条，然后沿着其宽度仔细裁剪以使对于横截面的任何压缩损坏最小化。然后安装该样品，使它的边缘向上朝着显微镜的透镜。使图像聚焦，并用软件提供的基线测量来测量。沿着样品的边缘测量了五个点，来确定样品的平均蓬松度。对同一纤网测试多个样品。在使用根据本发明实施方案的方法加工纺粘非织造纤网之后，该纤网膨胀到0.0267cm的平均蓬松度，且标准偏差是0.0053cm，其是初始纺粘非织造纤网的蓬松度的至少约1.7倍。
对于至少一个样品，使用目数25个孔/线性英寸(即“25目”)的成形筛。更具体地，该成形筛具有嵌套五边形的图案，其具有从五边形的一个平坦侧到它的尖锐顶侧测量为约0.050英寸的孔，并且这些孔由宽度约0.007英寸的界区隔开。这种膨胀的纺粘非织造样品具有高达0.036cm的测量蓬松度，这是纺粘非织造纤网的初始蓬松度的约3.0倍扩大。
当在装置如Textest FX 3300透气性测试仪(其是申请人用于本文数据的测试装置)中测量时，10.25gsm的纺粘非织造纤网还具有平均约1080立方英尺/平方英尺/分钟(ft3/ft2/分钟)，或约329立方米/平方米/分钟(m3/m2/分钟)的初始透气性。在根据本发明实施方案在上述相同的成形筛阵列上加工纺粘非织造纤网之后，透气性增加到平均约1420ft3/ft2/分钟或433m3/m2/分钟，且标准偏差为120ft3/ft2/分钟或37m3/m2/分钟，这意味着初始纺粘布的透气性至少约1.2倍的透气性增大。当通过前述的25目筛(即目数25个孔/线性英寸的成形筛)加工时，透气性增加到高达1620ft3/ft2/分钟或494m3/m2/分钟，这意味着初始纺粘布的透气性至少约1.5倍的透气性增大。
实施例2
根据本发明的实施方案，在上述成形筛的阵列上，还将纺粘非织造纤网作为层合体(复合材料)的一部分来液压成形。这种液压成形的复合材料应当具有足够的完整性，以使得层将不剥离和变得分开，这会在液压成形的复合材料构成吸收性器物时产生转化问题。甚至非常少量的分层力，即抵抗两个层剥离的分层的力，对于大部分转化方法应当足够。当通过剥离力测试方法测试时，根据本发明实施方案的液压成形的复合材料表现出至少约3.0g的分层力，该剥离力测试方法测试包括将2英寸宽的任何品牌的遮蔽胶带的片施加到复合材料的非织造物侧，长度8-10英寸，用手牵拉该胶带离开膜侧约2-3英寸的距离，和将该膜和该胶带置于膜工业中常用的任何拉伸测试装置的钳夹中。然后可以启动5英寸/分钟的钳夹分开速度，并且拉伸测试装置计算当两层剥离时力量规所经受的平均力。在本发明的一些实施方案中，测量的分层力高达几乎20g。
通过操控前述图10和11所示的压区层合方法中的熔融温度和压区压力，可以增加分层力，但是应当使层合条件平衡，以使得非织造物的全部纤维不完全压缩到复合前体材料的聚合物侧中。图11所示的真空层合方法会产生较弱的粘结(即分层力小)，但是仍然在本文所述的限度内，并且对于大多数转化方法是足够的。根据本发明实施方案的材料可以用作吸收性器物中的层。
实施例3-10
使用43.5目(43.5个孔/线性英寸)筛和60目(60个孔/线性英寸)筛，在不同的水压来液压成形平均厚度约133微米(0.0052英寸)和平均透气性约311m3/m2/分钟的名义上10gsm的纺粘非织造纤网。表I列出了使用43.5目筛在400psi-550psi的水压所形成的液压成形的非织造纤网的厚度和透气性，表II列出了使用60目筛在315psi-500psi的水压所形成的液压成形的非织造纤网的厚度和透气性。
表I：用43.5目筛液压成形的非织造纤网
使用43.5目筛，纺粘非织造纤网的平均厚度膨胀到其初始厚度的约1.44倍-约1.64倍(即增加约44％-约64％)的厚度，而平均透气性增加到其初始透气性的约1.26倍-约1.53倍(即增加约26％-53％)，并且厚度和透气性中的最大增加在最高水压获得。
表II：用60目筛液压成形的非织造纤网
在每个压力，纺粘非织造纤网的平均厚度膨胀到其初始厚度的约1.34倍-约1.62倍(即增加约34％-约62％)的厚度，而平均透气性增加到其初始透气性的约1.24倍-约1.42倍(即增加约24％-约42％)，并且厚度和透气性的最大增加在最高水压获得。
本发明的实施方案提供了一种液压成形的膨胀的纺粘非织造材料，其具有用于柔软度的高蓬松度，和用于凉爽和快速流体拦截的高透气性，其会适于顶部片，即将接触吸收性器物的穿用者皮肤的顶部片。吸收性器物例如卫生护垫和妇女卫生巾会受益于更凉爽、更柔软的顶部片。本发明的实施方案还提供了一种液压成形的复合材料，在膜层中具有有孔微延伸单元，其可以最佳地适用于低流体应用例如卫生护垫。膜层可以为非织造材料增加强度，以及提供再润湿性能增强，但是不具有有孔大延伸单元，液压成形的复合材料不能快速拦截大体积的流体。所以，根据本发明的实施方案，使用包含高于40个单元/线性英寸的目数(即微延伸单元)的液压成形的复合材料，可以最佳适用于引入增加了大延伸单元的上述方法的前体纤网。
在已经整合了大延伸单元之后，根据本发明实施方案的液压成形的复合材料由于大延伸单元之间界区上的微延伸单元而特别柔软和舒适。液压成形的复合材料还具有快速流体拦截，这对于用作吸收性器物中的顶部片或ADL是期望的。膨胀的纺粘非织造材料本身也可以用作吸收性器物中的顶部片或者不需要流体阻隔的其他应用中。如果液压成形的复合材料在膜层中具有无孔的延伸单元，则该液压成形的复合材料可以充当衬片，因为未开孔的单元会提供流体阻隔，同时仍然提供柔软度的益处。
根据本发明实施方案的液压成形的膨胀的纺粘非织造材料和液压成形的复合材料，在吸收性器物以及可以受益于本文所述的本发明实施方案所提供的性能和表现的其他类型的装置中有许多应用。例如，本发明的实施方案可以提供适于其他吸收性器物的材料，其他吸收性器物例如婴儿尿布或成人失禁产品，以及抹布、清洁装置、一次性衣服和需要空气和/或液体渗透性和高蓬松度的任何其他应用。
在一个实施方案中，液压成形的复合材料的聚合物膜可以是弹性体膜，并且包含弹性体膜和膨胀的纺粘非织造纤网的液压成形的复合材料可以用作吸收性器物或者需要柔软度和拉伸的任何其他产品中的侧面板、耳部、裤腿翻边、腰带等。
本文所述的实施方案代表了许多可能的实施和实例，并且并不意在将本发明必需限定到任何具体实施方案。相反，可以对这些实施方案进行不同的改变，并且本文所述的不同实施方案的不同组合可以用作本发明的一部分，即使没有明确描述，如本领域技术人员将理解的。任何这样的改变意在包括在本发明和所附权利要求书所保护的主旨和范围内。
