Abstract
本发明提供具有低蠕变的粘合纤维素纤维产品。该产品包括交联纤维素纤维和粘合剂。本发明还提供了制备粘合纤维素纤维产品以及包括该粘合产品的个人护理吸收产品的方法。
Description
发明领域
本发明总体上涉及一种纤维素纤维产品，特别涉及一种具有高压缩回复性的纤维素纤维产品。
发明背景
将交联的纤维素纤维方便地加入不同的纤维制品中，以提高制品的松密度、回弹性和干燥度。吸收制品，例如尿布一般由包括吸收纤维例如木浆纤维在内的纤维素复合材料形成。当将此类纤维复合材料加入吸收制品中时，此类纤维复合材料能够提供一种具有分别由吸收纤维和交联纤维所引入的高液体收集速率和高液体芯吸能力优点的产品。
个人护理吸收产品例如尿布、成人失禁用品以及女性卫生用品包括液体收集和/或分布层，这些层用于快速收集和然后将所收集液体分布至存储芯保留。为达到快速收集和分布，这些层可包括交联纤维素纤维，其赋予这些层以松密度和回弹性。
用于个人护理吸收产品如婴儿尿布的液体收集复合材料最好具有低密度，范围从约0.04-约0.06g/cm3。这样的低密度复合材料可以制造，但为经济地运输该低密度复合材料到达如尿布制造商用以引入尿布中，首先必须稠化该复合材料至密度为约0.2g/cm3。不幸的是，在运输后及引入吸收产品之前，低密度复合材料常不能回返至低密度。
因此，需要一种适合用作收集复合材料的产品，所述复合材料应可制造为具有低密度，稠化用于运输，然后回弹至或接近其原始密度用以导入吸收产品中。本发明为满足这些需要进行探索，并提供进一步相关的优点。
发明概述
一方面，本发明提供具有低蠕变的纤维素纤维产品。该产品包括交联纤维素纤维和粘合剂。该产品可任选包括其他纤维。
在本发明的另一方面，提供了形成低蠕变纤维素纤维产品的方法。在一个实施方式中，产品通过气流铺置法或挤出法形成。
在又一方面，本发明提供包括纤维素纤维产品的吸收制品。可以将该产品与一个或多个其他层结合以提供可以引入吸收制品如婴儿尿布、成人失禁产品和女性护理产品的结构。
优选实施方式的详细说明
一方面，本发明提供纤维素纤维产品，在产品稠化用于运输后，该产品回返至或接近其原始密度用以导入吸收制品中。低蠕变产品包括粘合的交联纤维素纤维。该产品具有与纤维内交联纤维相关的有利松密度和回弹性特性，以及经由纤维之间粘合所赋予的有利结构整体性。所述产品是粘合的网，其中交联纤维和网自身的粘合结构参与网的回弹性和液体收集性能。
在本发明中，纤维之间的粘合可通过用粘合剂处理纤维来实现。在一个实施方式中，粘合剂是胶乳。在一个实施方式中，产品是用胶乳和胶乳固定剂处理交联纤维素纤维来形成的。
所述产品可如下形成：(1)形成交联纤维素纤维的网；(2)用粘合剂处理网；和(3)以足以导致纤维之间粘合的温度和时间来加热所述网。所述产品可通过气流铺置、湿法成网、泡沫形成和挤出工艺形成。
根据本发明形成的产品的初始密度范围为约0.02-约0.06g/cm3。这样的低密度复合材料可稠化为高密度产品，该高密度产品的密度为约0.075-约0.2g/cm3。稠化产品回返至或接近其初始密度。在0.5psi下7天后，根据本发明形成的产品回返至其初始密度的约75-约100％。
