Description

用无机含硫还原剂制备抗紫外羊毛织物
技术领域
本发明涉及一种功能织物的制备方法，尤其是一种使用无机含硫还原剂制备抗紫外羊毛织物的方法。
背景技术
将纳米粒子引入纺织纤维中，可以制备得到功能性纤维材料。目前将纳米粒子引入羊毛纤维的制备方法很多，如：吸附法，溶胶凝胶法，层层组装法，涂层法等。然而，吸附法通过主要通过分子间范德华力和离子键力使纳米粒子吸附到羊毛纤维表面，水洗牢度较低；溶胶凝胶法和层层组装法的工艺过程较长，且较难控制；涂层法是利用粘合剂将纳米粒子粘合到羊毛纤维表面，降低了羊毛纤维对人体的亲肤性。
羊毛角蛋白是一种富含胱氨酸的蛋白质，胱氨酸中的二硫键是分子间相互交联，构成稳定的网状结构，是羊毛蛋白不溶于水的本质原因。无机含硫还原剂可以将二硫键还原成巯基，已经广泛用于羊毛角蛋白的溶解。
发明内容
本发明所要解决的技术问题是，针对以上现有技术存在的缺点，提出一种使用无机含硫还原剂制备抗紫外羊毛织物的方法。该制备技术简单易行，成本低廉，对羊毛织物的强力损伤小，不改变羊毛纤维表面性能，氧化锌纳米粒子在羊毛织物上具有良好的牢度；该制备过程中未使用任何粘合剂，无毒无害。
为了实现上述目的，本发明采取的解决方案为：一种使用无机含硫还原剂制备抗紫外羊毛织物的方法，其特征在于包括以下步骤：
（1）溶解液的制备：将无机含硫还原剂、尿素和十二烷基硫酸钠溶解到水中，然后加入氧化锌纳米粒子，剧烈搅拌下得到分散有氧化锌纳米粒子的溶解液；
（2）将羊毛织物在步骤（1）所得的溶解液中多次浸轧；
（3）将浸轧后的羊毛织物在红外线下辐照10-30min；
（4）将辐照后的羊毛织物浸渍于聚乙二醇溶液中凝固，然后水洗、烘干。
本发明的有益效果在于，（1）采用浸轧法使有限的无机含硫还原剂主要分布于羊毛纤维的表面，短时间的红外线辐照只能对羊毛纤维表面进行部分溶解，而不会损伤羊毛纤维内部，减小对羊毛纤维及织物物理机械性能的损伤；（2）在羊毛纤维表面部分溶解的羊毛蛋白形成蛋白质浓溶液，对纳米粒子具有粘附作用；（3）羊毛纤维表面形成的蛋白质浓溶液在聚乙二醇溶液中重新凝固，起到对纳米粒子的粘合、包裹作用；（4）制备过程中未使用任何粘合剂，无毒无害。
