Description
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NMMO水溶液制备远红外蚕丝织物的方法。
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蚕丝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,喂食法等。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蚕丝纤维表面,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蚕丝纤维表面,降低了蚕丝纤维对人体的亲肤性;喂食法是将纳米粒子混入家蚕食物中,使蚕丝纤维混入纳米粒子,缺点是效率很低。
N-甲基吗啉-N-氧化物是一种白色晶体,以一定比例溶于水即成无色透明的N-甲基吗啉-N-氧化物水溶液,主要用于植物纤维素高性能溶剂。在室温情况下,NMMO只对天然丝素蛋白有溶胀作用;超过100ºC后,NMMO可以彻底溶解丝纤维,得到浓度20%左右的再生丝蛋白溶液。
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NMMO水溶液制备远红外蚕丝织物的方法。该制备技术简单易行,成本低廉,对蚕丝织物的强力损伤小,不改变蚕丝纤维表面性能,电气石粉(600目以上)在蚕丝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NMMO水溶液制备远红外蚕丝织物的方法,其特征在于包括以下步骤:
(1)溶解液的制备:将NMMO加入到水中,形成浓度5%-40%的NMMO水溶液,然后在其中加入电气石粉(600目以上),超声振荡下得到分散有电气石粉(600目以上)的溶解液;
(2)将蚕丝织物在步骤(1)所得的溶解液中多次浸轧;
(3)将浸轧后蚕丝织物在红外线下辐照10-30min;
(4)将辐照后的蚕丝织物浸渍于甲醇溶液中凝固,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NMMO水溶液主要分布于蚕丝纤维的表面,短时间的红外线辐照只能对蚕丝纤维表面进行部分溶解,而不会损伤蚕丝纤维内部,减小对蚕丝纤维及织物物理机械性能的损伤;(2)在蚕丝纤维表面部分溶解的蚕丝蛋白形成蛋白质浓溶液,对纳米粒子具有粘附作用;(3)蚕丝纤维表面形成的蛋白质浓溶液在甲醇溶液中重新凝固,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。
