Description

一种防水透湿防钻绒的羽绒服专用绒面革的制造方法
技术领域
本发明属于超细纤维绒面革技术领域，具体涉及一种防水透湿防钻绒的羽绒服专用绒面革的制造方法。
背景技术
作为羽绒服的面料，一般要求具有良好的防水透湿性，而且还特别要求具有防钻绒性。羽绒服面料的防钻绒性通常有三种方式，一是使用高密度织物做面料，提高织物的防钻绒性能；二是在织物上覆膜或者涂层，通过薄膜或涂层来防止钻绒；三是在面料里层添加一层防绒布。第一种方法使用高密度织物做面料时，密度越高，成本越高，且制造方法较复杂，手感和触感不够柔软；后两种方法需要在面料上增加一道工序来达到防钻绒的技术要求，不但对手感有影响，而且涂层和防绒布的复合使用的胶水如果形成了连续膜或者厚度偏高，很容易影响面料的透湿性能，同时涂层和覆膜容易老化掉落。
发明内容
针对现有技术存在的问题，本发明的目的在于提供一种防水透湿防钻绒的羽绒服专用绒面革的制造方法，防止羽绒服钻绒的同时，面料具有较好的防水透湿性能。
为达到上述目的，提出以下技术方案：
一种防水透湿防钻绒一种防水透湿防钻绒的羽绒服专用绒面革的制造方法，包括如下步骤：
1）制作多组分的海岛超细纤维，多组分中含有低熔点树脂，所述低熔点树脂为低熔点PET或低熔点NY；
2）将步骤1）的海岛超细纤维经牵伸、卷曲、切断、开松、梳理、铺网、针刺、烫平制得无纺布；
3）将步骤2）的无纺布经聚氨酯树脂浸渍液浸渍、凝固、水洗后，再利用80-100℃的甲苯或60℃的5wt%NaOH水溶液开纤处理，得到超纤基布；
4）对步骤3）制得的超纤基布依次进行扩幅定型，得到产品；
5）对步骤4）制得的产品进行染色、片皮，防泼水处理制得染色超纤基布；
6）对步骤5）制得的染色超纤基布进行烫压处理，使内部的低熔点纤维粘结；
7）对步骤6）的染色超纤基布进行气流柔软、磨毛处理制得防水透湿防钻绒绒面革产品。
进一步地，步骤1）中的海岛超细纤维通过定岛纺丝工艺或皮芯复合工艺制备得到。
进一步地，当通过定岛纺丝工艺制备得到海岛超细纤维时，“岛”组分为PET、PBT、PTT、PLA、NY6、NY56、NY66或NY510，“海”组分为PE、COPET或PVA，在“海”组分中分散有低熔点树脂。
进一步地，“岛”组分占总纤维质量的55-70%，“海”组分占总纤维质量的30-45%；分散在“海”组分中的低熔点树脂组分占总纤维质量的3-10%。
进一步地，当通过皮芯复合工艺制备得到海岛超细纤维时，“芯”组分包含两种树脂，一种是不溶于甲苯和稀碱溶液的高熔点树脂，选自PET、PBT、PTT、PLA、NY6、NY56、NY66或NY510，一种是溶于甲苯和稀碱溶液的树脂，选自PE、COPET或PVA；“皮”组分包含两种树脂，一种是低熔点PET或低熔点NY，一种是溶于甲苯和稀碱溶液的树脂，选自PE、COPET或PVA。
进一步地，“芯”组分中不溶于甲苯和稀碱溶液的高熔点树脂占总质量的20-35%，“芯”组分中溶于甲苯和稀碱溶液的树脂占总质量的20-35%；“皮”组分中低熔点PET或低熔点NY占总质量的3-10%，“皮”组分中溶于甲苯和稀碱溶液的树脂占总质量的40-47%。
进一步地，低熔点树脂的熔点为110-130℃。
进一步地，聚氨酯树脂是由多元醇、扩链剂和异氰酸酯聚合而成的熔点超过180℃的聚脲型聚氨酯，所述多元醇为PTMG、PBA、PPG中的一种或几种，扩链剂为EG、MEA、MOCA中的一种或多种。
进一步地，扩幅烘干的温度不超过110℃，烫压温度控制在130-150℃，气流柔软处理时间控制在20-40min。
进一步地，所述的高熔点的树脂的熔点为220-265℃。
本发明的有益效果在于：
1）本发明在海岛超细纤维中添加了低熔点树脂，通过烫压后，材料中的低熔点树脂纤维能形成立体网状结构，可以有效的防止羽绒服内的短羽绒钻出，
2）本发明制备得到的绒面革除防钻绒外，还具有较好的防水透湿性能，超细纤维的荷叶效应+防泼水处理，防水性能远超常规纤维的防水性能。
