Description

一种羊毛织物的阻燃整理工艺
技术领域
本发明属于纺织技术领域，涉及一种功能性羊毛织物，具体为一种羊毛织物的阻燃整理工艺。
背景技术
羊毛属于角蛋白类的纤维状蛋白，含有较多的半胱氨酸、胱氨酸、甲基硫氨酸，是具有折叠分子结构的交联多肽。由于羊毛含氮量高并极易吸湿，具有高点火温度，低燃烧热和低火焰温度，因而表现出很高的阻燃性。但是，制成的羊毛织物由于加入了一些助剂使其阻燃性能下降，致使羊毛纤维容易燃烧，大大限制了羊毛的安全使用，因而对之进行阻燃处理，降低其可燃性具有很高的现实意义。
关于羊毛的阻燃处理，最早为浸渍磷酸盐、硼酸盐溶液再烘干，所得阻燃羊毛织物不耐洗；后期采用卤系及磷卤协同阻燃体系，但由于卤系阻燃剂对环境及人体的危害，目前已遭淘汰；国际羊毛局推广的“Zirpro”工艺是工业界使用较久的比较成功的羊毛阻燃方法，该法是以六氟钛酸钾及六氟锆酸钾为阻燃剂，在酸性条件下处理，不影响织物手感，但由于目前重金属对环境和人体均有不同程度的伤害，而且钛、锆对人体的生理功能尚不明确，使用该法存在一定的风险。
发明内容
本发明解决的技术问题：为了克服现有技术的缺陷，获得一种能够加强羊毛蛋白纤维的交联作用，使羊毛织物具有稳定的阻燃性能的工艺，且整理工艺不影响织物的手感，对环境友好，本发明提供了一种羊毛织物的阻燃整理工艺。
技术方案：一种羊毛织物的阻燃整理工艺，所述工艺包括以下步骤：
(1)将羊毛织物与次氯酸钠水溶液混合，在常温条件下避光反应2～5小时，反应结束后，加入乙二醇中和残余的次氯酸钠，去离子水反复洗涤，自然晾干；
(2)将步骤(1)处理后的羊毛织物浸渍于转谷氨酰胺酶溶液中，pH为6～8.6，织物与酶溶液的重量浴比为1:13～25，处理温度为30～55℃，处理时间为2～4.5小时；
(3)将步骤(2)酶整理后的羊毛织物置于含磷整理液中，含磷整理液的重量百分含量为1％～6％，织物与整理液的重量浴比为1:15～30，处理温度为30～50℃，处理时间为1～5小时，然后进行皂洗和水洗，烘干。
优选的，步骤(1)中羊毛织物与次氯酸钠的质量比为12～25:1。
优选的，步骤(1)中乙二醇的加入量为次氯酸钠摩尔量的0.3～0.8倍。
优选的，步骤(2)中转谷氨酰胺酶的浓度为20～45U/L。
优选的，步骤(3)中含磷整理液选自阿伦磷酸、阿仑膦酸钠、或磷酸乙醇胺。
优选的，步骤(3)中含磷整理液中的缓冲液选自磷酸氢二钾、磷酸氢二钠、磷酸氢钾、磷酸氢钠或硼酸。
有益效果：(1)本发明所述工艺能够赋予羊毛织物稳定的阻燃性能，且对羊毛的其他性能也有一定的提高，尤其是羊毛织物的强力、防毡缩；(2)所述工艺对羊毛织物具有强力修复作用，与单纯的化学整理相比，本发明无污染且更加环保。
