Description

一种多层复合导流材料
技术领域
本发明涉及一种多层复合导流材料。所述多层复合导流材料主要用于纸尿布、卫生巾等一次性使用卫生用品。
背景技术
导流材料位于一次性使用卫生用品（如：纸尿布、卫生巾等）表层与吸收芯层的中间位置，主要起到传导、扩散、快速下渗和防止反渗的作用，从而使得液体在到达该层后快速且均匀地沿长度方向传递到吸水芯层，最大限度地提高芯层内SAP的吸收效率，有效防止卫生用品漏液现象发生。
现有一次性使用卫生用品所用的复合型导流层为液体吸收性材料，其目的是通过吸收性材料暂时储存液体，然后再将液体扩散导流至吸收芯层。该复合型导流层厚度较大，纤维素纤维和超吸水纤维使用量较多，故价格昂贵，且液体并非能够完全渗入芯体中去，仍有较多部分残留在导流层吸收性材料中，导致产品回渗量较大。另，该类复合型导流层采用无尘纸工艺（干法造纸工艺）制造，生产过程中会产生大量粉尘，生产工艺复杂，且存在材料掉粉现象，给卫生用品的生产过程带来诸多不便。
发明内容
本发明的目的是，提供一种多层复合导流材料。
为实现上述目的，本发明采用以下技术方案：一种多层复合导流材料，由三层纤维网构成，上层纤维网采用热风粘合加固而成，中间层和底层纤维网通过水射流缠结加固而成。纤维网之间通过喷洒湿强性热熔胶进行粘结。
所述表层纤维网采用皮芯双组份纤维，其中皮层为聚乙烯，芯层为聚丙烯、聚酯两种树脂中的任意一种；纤维长度为30~70mm，细度为3~40D；纤维经市购的多次亲水纺丝油剂处理。经本领域公知的梳理、牵伸、去杂乱工艺，使所述热风粘合纤维网中的大部分纤维沿长度方向排列较规整，其中交错的细长条纤维束之间的间隙长度为0.2~4.5mm。表层纤维网克重为15~45g/m2。
所述中间层纤维网和底层纤维网由黏胶纤维和聚酯纤维两组分组成。中间层纤维网采用的黏胶纤维的比例为30～60wt%，纤维网的克重为50~80 g/m2，采用2道水射流缠结，水针压力为50~70bar，纤维网结构较蓬松。底层纤维网采用的黏胶纤维的比例为50～95wt%，纤维网的克重为70~100g/m2，采用3道水射流缠结，水针压力为70~90bar，纤维网结构较密实。中间层纤维网的厚度和孔径均大于底层纤维网，密度小于底层纤维网，两层间形成漏斗状液体传输结构，且两层上下间存在势能差，可使液体迅速下渗、快速扩散。
如上所述的多层复合导流材料，以上各层纤维网之间采用湿强性热熔胶进行胶合；所述湿强性热熔胶为Henkel 5811u或Bostik 4660或Fuller 1088三种中之一种；施胶方式为欧米伽喷胶或纤维喷胶或螺旋喷胶三种中之一种，优选欧米伽喷胶。
本发明的有益效果在于：液体在多层复合导流材料中主要沿长度方向扩散，在表层纤维网上扩散面积小，在底层纤维网上扩散面积大，底层纤维网与上层纤维网扩散面积比大于15，此特性使得所述导流材料与贴肤面层材料接触的液体少，反渗至面层材料的液体就更少，故可有效减少尿液等排泄物对皮肤的刺激。所述导流材料的另一面与吸收芯层接触，因液体扩散面积大，利于液体更迅速、有效地被吸收芯层吸收，提高了吸收芯层的吸收效率。此外，所述导流材料多次渗透迅速，回渗量少，经LISTER-CA渗透仪测试，前三次渗透时间均小于3s，回渗量小于等于0.1g。
具体实施方式
多层复合导流材料由三层纤维网构成，上层纤维网采用热风粘合加固而成，中间层和底层纤维网通过水射流缠结加固而成。
表层纤维网采用皮芯双组分纤维，其中皮层为聚乙烯、芯层为聚酯，纤维长度为30~70mm，细度为3~40D，纤维经多次亲水油剂HA-YJ-1309D/HA-YJ-1308（市购）处理。纤维经锡林梳理后转移至道夫，通过缩小道夫与凝聚辊之间的速度比，使梳理后的大部分纤维沿长度方向排列规整。纤网成型后转移至烘箱网帘上，由于纤网的输出速度小于烘箱网帘的速度，在接触的瞬间，网帘对纤网有一个牵拉的作用，使得经热风固化后的纤网中交错的细长条纤维束之间的间隙长度为0.2~4.5mm。该纤维网的平方克重为15~45g/m2。
中间层水射流缠结纤维网采用的黏胶纤维的比例为30~60wt%，底层水射流缠结纤维网采用的黏胶纤维的比例为50~95wt%。中间层水射流缠结纤维网的平方克重为50~80g/m2，采用2道水射流缠结，水针压力为50~70bar。底层水射流缠结纤维网的平方克重为70~100g/m2，采用3道水射流缠结，水针压力为70~90bar。
三层纤维网之间通过湿强性热熔胶Henkel 5811u或Bostik 4660或Fuller 1088进行粘结，喷胶方式为欧米伽喷胶或纤维喷胶或螺旋喷胶三种中之一种，优选欧米伽喷胶。
根据上述方法，制造出多层复合导流材料样品1、样品2、样品3和样品4，各样品及对比样（目前普遍应用于一次性使用卫生用品的导流材料）参数如表1所示：
表1

对比样 普通热风导流无纺布 4D-PE/PET双组份纤维，纤维长度38mm，克重为40gsm。
配置一定量的生理盐水，并在生理盐水中加入0.5%靛蓝，备用。
采用LISTER-CA渗透仪，分别测试样品和对比样多次渗透、回渗量的数据。
扩散长度测量方法：将测试样品放在铁板的滤纸上，调节加液漏斗的高度，使其下口的最下端距试样表面5mm~10mm。用移液管准确移取测试溶液5mL于调节好的漏斗中，然后迅速打开漏斗节门至最大，使溶液自由地流到试样的表面上，溶液流完后，将漏斗节门关闭。连续放液3次，然后测量出生理盐水在试样上表面和下表面的扩散长度和宽度，多次测试，取平均值，并计算出面积。
测试结果如表2所示：
表2
测试结果表明，本发明提供的多层复合导流材料，由于表层纤维网的特殊结构，使液体下渗迅速，且扩散面积小，底层纤维网中含有亲水性和导湿性好的黏胶纤维，能够充分、迅速地将表层纤维网中的液体吸附下来，同时通过其上松下密的结构，使液体主要沿长度方向扩散并单向向下渗透，故回渗量极小。
以上结合实施例对本发明进行了较为详细的描述，但这并不构成对本发明内容的限制。在同样的构思下所做出的修改、变化及变型，均落入本发明的保护范围。
