Abstract
一种三维热成形双组分无纺材料,它包括一种有弹性的双组分材料层,该双组分材料层所形成的许多波峰通过通道而相互分离开。并且该双组分材料层具有单位重量0.5～7.0盎司/平方码。双组分材料层由结构纤维和适合于热成形的遇热可起作用的粘合组分组成。本发明还揭示了这种适合用于个人吸收护理产品如卫生巾,一次性尿布,失禁护理衬垫等的各种外形。
Description
发明背景
发明领域
本发明涉及一种双组分纤维无纺材料，该材料显示出超高弹性，这是由于其材料产品的形状和条件而产生的结果。该材料适合用于包括尿布，妇女卫生巾，失禁服装和运动裤的个人护理吸收制品的体侧衬垫材料，用于个人护理吸收产品的镶嵌件，和用于这种制品吸收芯的外层。该材料保证了排泄物的分离和保留，空气的循环，月经的控制和保留，和流体的分布和保留。
现有技术
吸收性个人护理制品如卫生巾，一次性尿布，失禁护理衬垫等已被广泛使用，并已做了很大的努力以改善这些制品的有效性和功能性。不能与人体形状相吻合和不适合用者运动的过去的厚而平的个人护理产品已广泛的被具有回弹适合于三维的、人体形状的产品所代替。
尿布皮炎是由湿的封闭的尿布长时间与穿戴者的皮肤接触所造成的一种皮肤情况。这种长时间接触可导致最外皮肤层的过度水化，因此减小了皮肤起阻挡作用的能力。因此，这就增加了刺激物的浸透，皮肤对有形损害的敏感性，并由于细菌使皮肤发病。保持正常的皮肤水化范围有助于皮肤保持最佳的阻挡性。因此，重要的是个人护理吸收制品在可能的范围内在贮有人体流出物的时候防止过度皮肤水化，并对穿戴者提供柔软、干燥和舒适感。
具有扁平衬垫的液流吸藏的吸收服装抑制人体流出物附着于穿戴者的皮肤上。因为要防止渗漏，产品结构有紧配合特点，热和水分被避免从产品中逸出。这个问题在个人护理吸收产品的对人体伤害区域中是最厉害的。扁平衬垫把一大的接触面积提供于皮肤，其可起一通道作用以把吸收芯不能储存的皮肤自由液体引导到背面，尤其是当产品在伤害点处在压力下，因为扁平衬垫不能提供使穿戴者和自由液体分离的足够程度。此外，扁平衬垫不能使个人护理吸收产品的伤害区域与周围空气互通以使湿气将在伤害区域被减少以得离开伤害区。
已知用来实现个人护理吸收产品的内部区域与周围空气互通的各种措施，其中包括透气背部片材，排泄孔，和边孔。然而，这些方法具有各种不同的缺点，使其实际与实现正常的、未封闭皮肤水化程度的设计有差异。例如，透气背部片材为干燥经过背部片材到吸收产品的内部提供一通道。然而，湿的吸收物在皮肤与周围空气之间能够防碍理想的联系。此外，通过背部片材的排泄孔和边孔会导致或是贴着皮肤被阻塞或是提供泄漏通道。
其它的方法包括在衬垫下使用折叠的吸收芯或层以干燥衬垫，即皮肤接触层。然而，这些方法要求不良的工艺方案和经济情况，并且不能真正地使用周围的空气干燥穿戴者的皮肤，相反，他们仅是干燥皮肤接触层。因此，这就需要一种材料，该材料可用于其中包括个人护理产品的衬垫材料，如尿布，运动裤，失禁服装，卫生巾，绷带等，该材料能够减少产品伤害区的湿度和穿戴者的皮肤水化程度。
本发明的概述
本发明的目的是提供一种具有弹力、强力、和类似布料特性的无纺材料。
本发明的另一目的是提供一种用于生产具有弹力、强力和类似布料特性的无纺材料的方法。
本发明的另一目的是提供适合用于个人护理吸收产品的无纺材料，其产品使伤害区域能通过空气通路或通道与周围空气互通，从而在个人护理吸收产品的整个区域中减少湿度。
上述的目的通过一种三维热成型双组分纤维无纺材料而实现的，该材料构成一种有弹性的双组分材料层，其材料层形成有多个波峰。这些波峰是通过通道而相互分离开。根据本发明的无纺材料的重量范围约为0.5～0.7盎司/平方码(约为17～24克/平方米)。这种材料的双组分层是由结构组分和适合于热成形的遇热起作用的粘合组分构成。
用于生产根据本发明三维弹性可压缩的，双组分纤维无纺材料的方法包括把一种结构纤维组分和一种遇热可起作用的粘合组分形成为具有单位重量范围约为0.5～0.7盎司/平方码的无纺纤维网。该无纺纤维网被加热到足以熔融遇热可起作用的粘合组分的温度，该温度低于结构纤维组分的熔融温度，其结果是形成一种柔韧的无纺纤维网。然后柔韧的无纺纤维网被加工成形为具有通过通道而相互分离开的许多波峰的成形纤维网。所获得的成形纤维网随后被冷却以固化熔融的遇热可起作用的粘合组分，结果形成所希望的最终产品。
本发明的上述内容和其它特征以及优点通过结合阅读实例和附图、最佳实施例的详细描述将会更加进一步清楚。实例和附图的具体描述仅仅是解释说明而不限定由附加的权利要求和其等同物而确定的本
发明的范围。

最佳实施例的描述
本发明的无纺材料的有弹性的双组分材料层具有基本上均匀分布的纤维间结合，并且由一种结构纤维组分和一种遇热可起作用的粘合组分组成。可添加的粘合组分作为外表粘合剂或可形成如下所述的无纺纤维网的纤维的一部分。适合用于本发明的纤维是包括卷曲的单组分纤维的卷曲纤维，这种纤维是由均相聚合物成分制成的，并且是卷曲的多组分共轭纤维，这种纤维含有至少2个组分聚合物成分，它们沿着纤维的整个长度上占据不同的横截面。尤其适合用于本发明的是卷曲共轭纺粘或短纤维，并且根据本发明的另一实施例最适合的纤维是双组分共轭纤。这些纤维当中，具有不同熔融点的组分聚合物的多组分共轭纤维尤其适合本发明，因为粘合无纺纤维网无需附加的和额外的粘合组分，由此简化了无纺纤维网的制造工艺。
纤维的卷曲程度是可变化的，从而对纤维提供不同的特性，其中包括不同的密度、强度、柔软度和质地。一般情况下，根据本发明高卷曲纤维的结合提供的是有弹性的、柔软的纤维网。适合于本发明无纺材料的纤维每伸直英寸至少有2个卷曲，较好的是每伸直英寸有约2至5个卷曲，并且最好的是每伸直英寸有约3至30个卷曲，这些是根据ASTM D-3937-82测量的。适合用于本发明的纺粘纤维和短纤维具有约5至100微米的平均直径，较好的是10-50微米。
在全部说明书和权利要求中所使用的术语“纤维”均表示短纤维和长丝纤维，他们都是连续纤维。术语“纺粘纤维”表示由下方式形成的纤维，由喷丝板上的许多相对细小的，通常为圆的毛细孔挤压熔融的热塑性聚合物形成为长丝，然后通过一引出装置或其它已知的拉伸机快速拉伸被挤压出的长丝，从而将分子取向和物理强度赋予给长丝。拉伸的纤维以非常随机的形式被放置到一收集面上，以形成一种具有基本上均匀密度的无纺纤维网。这种无纺纤维网随后被粘合以赋予物理完整性和强度。用于生产纺粘纤维和由其生产的纤维网的工艺方法已被揭示在例如US4,340,563和US3,692,618中。术语“短纤维”表示不连续的纤维。短纤维是用传统的纤维纺丝工艺而生产的并随后切成短纤长度，较好的长度范围为约1至8英寸。这样的短纤维紧接着被梳理，湿法成网，或气流成网，然后热粘合以形成一种无纺纤维网。
适合用于本发明三维双组分纤维无纺材料的无纺纤维网可由含有组分聚合物的共轭纤维而生产的，其组分聚合物具有不同的熔融温度，以致使低熔融温度的聚合物，即粘合组分，能被熔融并成为粘合剂，而使高熔融温度的聚合物，即结构组分，保持其无纺纤维网的物理完整性和结构性。尤其在交叉接触点处，熔融粘合组分聚合物自身粘附到相邻纤维。因此，粘合组分与结构组分之间的熔融温度差至少为5℃，较好的是至少为10℃。根据本发明，适宜的共轭纤维在沿着纤维的实际整个长度上粘合组分聚合物至少部分地暴露在表面。根据本发明的一个较佳实施例，共轭纤维包括粘合聚合物20～80％，以重量计。根据本发明的一最佳实施例，所述的共轭纤维包括以重量计的粘合聚合物40～60％。本发明的卷曲纤维无纺纤维网被粘合，从而具有弹性结构，该弹性结构在整个纤维网中包含有纤维间的结合。用于本发明的粘合工艺将是升高被堆置的无纺纤维网的温度，以触发其粘合组分，而无需在纤维网上施加压实力。熔融或被触发的粘合组分聚合物在整个纤维网中，尤其在纤维交叉接触点上，形成基本均匀的纤维间的粘结，以提供一种有弹性的无纺纤维网，该纤维网是柔软的但是牢固的并具有高能级的弹力。使用本发明无纺材料可生产的举例说明的制品包括个人护理吸收产品和其组件，如在吸收芯上面的符合于人体形状的卫生巾外层，形状固定的尿布组件，失禁护理产品等。
适合于使用与本发明有关的粘合工艺包括通气粘合，热烘箱粘合，和红外加热装置粘合工艺方法。尤其较好的是通气粘合工艺。粘合工艺的时间和温度是可变化的，以适应选定粘合设备的温度和速度制约。然而，重要的是粘合工艺的持续时间和温度的组合要足够的长和高以致熔融纤维网的粘合组分，但不要过长和高以致熔融结构组分，由此保持物理和尺寸完整性并防止纤维网的收缩。例如，当聚丙烯和聚乙烯用作共轭纤维无纺纤维网的组分聚合物并使用通气粘合工艺，流经过通气粘合器的空气可具有温度230-280°F，速度约为100～500英尺/米，纤维网在粘合器中停留时间最好少于6秒。
适合于本发明的单组分可由已知能形成纤维的各种热塑性聚合物而生产。
同样地，共轭纤维可由所提供的热塑性聚合物的各种组合物形成，如上所述，所选择的聚合物具有足够的熔点差，最好具有至少约10℃的熔点差，并且最好具有不同的结晶、固化和/或弹性特性。选用的聚合物之间的熔点差便于加热被触发的粘合工艺，结晶和固化特性的差异促进纤维卷曲，尤其卷曲通过热激活的潜在卷曲，并且弹性特性上的差异便于机械卷曲成形工艺。适宜的聚合物选自由聚烯烃，聚酰胺，聚脂，聚碳酸酯，聚苯乙烯，热塑性弹性体，含氟聚合物、乙烯基聚合物，和它们的混合物和共聚物所组成的组。适宜的聚烯烃，但不限于，聚乙烯，聚丙烯，聚丁烯等；适宜的聚酰胺包括，但不限于，尼龙6，尼龙6/6，尼龙10，尼龙12等；适宜的聚酯包括，但不限于，聚对苯二甲酸乙二酯，聚对苯二甲酸丁二酯等。用于本发明尤其适宜的聚合物是包括聚乙烯的聚烯烃，例如，线性低密度聚乙烯，低密度聚乙烯，中密度聚乙烯，高密度聚乙烯和其混合物；聚丙烯；聚丁烯和其共聚物以及混合物。此外，适宜纤维成形的聚合物可具有混合在其内的热塑性弹性体。在这适宜的聚合物中，对于适宜共轭纤维的结构组分的特别适宜的聚合物包括聚丙烯和聚丙烯与乙烯的共聚物，对于共轭纤维的粘合组分所特别适宜的聚合物包括聚乙烯，尤其是线性低密度聚乙烯，和高密度聚乙烯。此外，为提高纤维的卷曲性和/或降低粘合温度，和提高所形成的纤维网的耐磨牢度、强度和柔软度，粘合组分可包含有添加剂。例如，粘合聚合物组分可含有5～20％(重量计)的热塑性弹性体，如苯乙烯，乙烯-丁烯和苯乙烯的ABA′嵌段共聚物。这样的共聚物是可以买到的。适合添加聚合物的其它组是乙烯-丙烯酸烷基酯共聚物，如乙烯-丙烯酸丁基酯，乙烯-丙烯酸甲基酯，和乙烯-丙烯酸乙基酯，并且对于生产所希望特性的适宜量按粘合聚合物组分的总重量计约为2-50％。另外一些适宜的添加聚合物包括聚丁烯共聚物和乙烯-丙烯共聚物。
适合用于本发明的无纺材料具有较好范围约为0.5～7.0盎司/平方码(osy)的单位重量，即约为15-240克/平方米。
本发明无纺材料的遇热可起作用的粘合组分可以是以施加或喷洒粉末或液体的形式的外部热熔粘合，上述形式使其能分布于整个纤维网。尤其适合于本发明的粘合剂是普通的，热塑性热熔粘合剂，如以聚乙烯、聚酰胺、聚酯和乙烯-乙酸乙烯酯共聚物为基础的热熔粘合剂，作为各种状态的粘合剂被选定的熔融温度要低于材料结构组分熔融温度。
为了克服当前一次性吸收服装的缺点，希望提供一种适用于用作这种服装中衬垫的材料，其将使伤害区域和远离伤害区域的表面通过空气通路或通道与环境空气联通，以保证减少个人护理吸收产品整个区域中的湿度，同时，提供适宜的吸收特性，从而在经受穿戴者的压力时能保证个人护理吸收产品中低的漏泄。此外，衬垫材料将有柔软、干燥感，并在伤害之后在皮肤接触区域含有极少的自由液体以减少穿戴者不舒适和皮肤水化。根据一个实施例，本发明的无纺材料通过加入表面活性剂而被赋予有可湿性。
为使周围空气达到穿戴者的皮肤，本发明的无纺材料提供有弹性，抗皱突起的皮肤接触区域或波峰和在突起的皮肤接触区域之间形成的空气通路或通道以保证所希望的功能特征，其中包括湿度降低，因此有利于正常皮肤水合的理想维持以及所希望的吸收能力和舒适性。形成整体材料的结构材料的结构、几何形状和选择是本发明重要的方面。
本发明的另一目的是为减少皮肤刺激而提供一种用于把排泄物与穿戴者皮肤相分离开的方式。根据本发明，排泄物与穿戴者皮肤的分离是有可能的，这是由于无纺材料在材料的突起波峰之间的区域内有能储存排泄物的能力所造成的。
本发明的无纺材料可设计成能实行各种流体控制功能。图1a-1e示出了根据本发明材料的各种形状，其以无纺材料的波纹为基础。示于图1a-1e中波形实施例的材料具有单位重量为0.5～7osy，其波形实施例是一种波状有弹性的双组分结构。所述的材料通过下述的热成形工艺而提供有超弹性。根据示于图1a-1e的实施例，波纹较佳的数目为1/2～4波纹/英寸。
根据本发明的一个较佳实施例，设置在波状无纺材料波峰10内为一交替组分12，其取决于无纺材料的特殊应用。这些交替组分的用途通常是用于吸收进入通过成波状层顶面的液体。根据交替组分的性质，其可包括绒毛，SAP，纤维状SAP，气味控制装置，分配材料和波动材料，其材料能够设计成能保持住通过波状无纺材料顶面的液体和/或将其全部液体或部分液体输送到又一层材(未图示)。用于该交替组分的适宜材料包括，但不限于此，棉花绒毛，棉纸，织造材料，丝束，和特别是无纺材料，以及其组合物。天然和合成纤维的混合物也是很有效的。根据本发明的一个较佳实施例，如图1c所示，波状无纺材料填充有其自身结构材料。
图1b示出了根据本发明一实施例波状无纺材料的另一变化，其中在两波纹之间的间隔在通道11的底部处例如提供一接合区域13。根据本发明的一个较佳的实施例，波状无纺材料的两波峰10之间间距至少约为1/16英寸。
根据本发明的一最佳实施例，尤其适合于排泄物分离/保留和月经处理/保留，无纺材料形成有许多缝或小孔14，如图1e所示，其改善了材料性能，使其能把人体排泄物通过无纺材料输送到个人护理吸收产品中放置在无纺材料层下面的分配或波动材料上。本领域的技术人员应将清楚地知道，示于图1a-1d的包括加入的交替组分12如绒毛，SAP，纤维状SAP，气味控制装置，分配材料和波动材料，以及在通道11底部处形成的接合区域或凹部13的波状无纺材料所有特征可同样地应用于该实施例。
图2a-2e示出了本发明的三维热成形双组分纤维无纺材料的一些替换实施例。根据该实施例，波峰10是呈褶的形式，这些褶是由单层材料产生许多成对的向内面对的第一和第二折边15，16而形成的，所述的单层材料在横方向上是连续的。该实施例的无纺材料单位重量与示于图1a-1e的波状无纺材料是相同的，即为0.5～7osy。此外，褶密度相同于波状无纺材料的波纹密度，其含有1/2～4褶/英寸。如同在波状无纺材料的情况，该实施例的结构也有超弹性，这是由于在热成形期间构成无纺材料的纤维再熔化的原因而造成的。
根据该实施例的打褶的无纺材料的一种变化被示于图2b中，其中交替组分12被放置在褶内，适宜的交替组分12包括，但不限于此，波动，分配，SAP，绒毛，纤维状SAP，气味控制装置，干燥剂，或其它热成形结构。在褶中心，可加入一个已热成形的双“C”折18或“M”折叠材料17，以进一步增加纤维弹性。这是在本发明的范围之内的，本发明无纺材料的仅一部分是热成形的。例如，事实上，形成波峰10的褶不需要热成形，而填充材料12是热成形的。另一方面，褶是可热成形的，而填充材料是不热成形的。
除了交替组分被放置在褶内外，如示于图2d的有效颗粒20，如绒毛，SAM分配材料，和其它对热成形无纺材料提供有用的组分，能够热成形到波峰10的表面上。如示于图2a的这种组分21也可被放置在波峰10之间。这些方式实际提供了最快的流入率，从而导致泄漏减少，并在使用中提供较佳的配合和舒适。这些方式也适合于排泄物保留。
图2c示出了本发明热成形无纺材料的又一实施例，其中折边15、16是以这样一种形式而被制成，其最终形成基本上为半圆形的波峰。该实施例的半圆形波峰10适合于保持住填充材料12并且或是通过同用于形成半圆形波峰10的无纺材料一样的材料或是用熔吹或熔喷材料在连续的工艺中喷洒到底面上而封闭底部22。
图2d示出了打褶无纺材料的实施例，其相应于图1d所示的波状实施例，其中接合区域或凹部13是设置在相邻的波峰10之间。同样，图2e示出了相应于图1e所示的带有孔形式的波状无纺材料的本发明打褶热成形无纺材料的带有孔的实施例。
示出图1a-1e和2a-2e的热成形无纺材料的所有结构有助于排泄物保持在波峰之间，即，将排泄物装在接合区域13内。如果波峰10是充分靠近的，例如，如示于图2a的实施例，排泄物无法从图中看到或被掩敝并且被贮存以易于清理和尿布移开。此外，使用示出图2e的带有孔的实施例，使得有可能进行排泄物的排水，因此有助于分离。本发明的热成形无纺材料能起惰性或全长衬垫的作用。
因为使用于本发明热成形无纺材料结构的衬垫材料的被增加的表面积，则侧漏泄明显减少。液体流入到波峰之间的间隙内，因此减小或消除了液体流出衬垫的倾向。
用于与本发明超弹性，热成形无纺材料相关的其它三维形状被示于图3a-3i中。这些形状都可有至少下列两个功能：漏泄减少，排泄物漏泄减少，排泄物分离，排泄物保留，波动功能性，和潜在的，皮肤健康。图3a-3b表示了波状无纺材料的一种外形，其中波纹是由波峰10和通道11而限定的一种波浪形。如果这种结构被用作衬垫材料，它可通过将流体引导过通道11而达到防止侧漏。由于增加了贴附于人体的织物的表面积，使结构提供最快速的入流率。
图3b表示了一种波纹形结构，其中波纹是中凹的。材料外侧边缘上的较大波纹作为挡板以使流体流动并以此有助于防止侧漏。此外，这种结构还能使排泄物引导通过通道11。这样，由该实施例可提供多种功能性。图3c表示一类似的中凹结构表示一种更为普通的波状材料。图3d-3e表示了相应于图1所示结构的一些结构，其中接合区域13设置在波峰10之间。示于图3的实施例仅是表示于图3d实施例的一种中凹的变化，其中波峰10的高度比较于结构的外边缘对于结构中心是较低的。
一种树枝状结构，其中排泄物能被包围在示于图3f和3g的接合区域或波峰13内。对于尿和排泄物的侧漏被减少，尤其是沿着材料的外边缘的“树枝”对于材料中心是较高的。
最后，图3h-3i表示一种圈状结构，该结构根据刚性能用于把排泄物贮存在结构内的深槽中，以及能使与皮肤分离。包括绒毛和SAP，分配材料，气味控制装置等的附加功能材料可放在类似圈状的通道内并被密封以提供具有排泄物控制和尿漏泄控制的总的吸收体系。
根据如图4所示的本发明的又一实施例，热成形无纺材料包括许多波峰10和设置其之间的通道11。波峰10形成有许多槽口25，由此可提供对粘性流体如软粘排泄物较好的输送。槽口25足以使软粘排泄物流入到所有通道11内。
用于生产根据本发明的三维热成形双组分纤维无纺材料的工艺包括把一种结构纤维组分和遇热可起作用的粘合组分形成为一种无纺纤维网，该无纺纤维网具有单位重量范围约0.5～7.0osy。无纺纤维网随后被加热到足以熔融遇热可起作用的粘合组分而不熔融结构纤维组分的温度，由此提供柔韧的无纺纤维网。该柔韧的无纺纤维网然后被加工成形为具有许多由通道而相互分离的波峰的成形纤维网。成形纤维网然后被冷却以固化被熔融遇热可起作用的粘合组分。
虽然在此所揭示的实施例已被认为是最佳的，但可做出的各种变更和改善都不会脱离本发明的精神和范围。本发明的范围由附加的权利要求而表示出。属于等同的意思和范围内的所有变化都定为被包含在本发明之内。
