技术领域
本发明涉及化学纺织品加工技术领域，具体涉及一种疏水性亚胺纤维纺织品的染色工艺。
背景技术
化学纤维是用天然高分子化合物或人工合成的高分子化合物为原料，经过制备纺丝原液、纺丝和后处理等工序制得的具有纺织性能的纤维。现有化学纤维耐火性能较差，而且不具备空气净化功能，芳烃聚酰亚胺纤维具有非常好的热稳定性，抗火性，抗化学性，绝缘性，以及高强度及模数，特别适合用于室内外的装饰地毯或地垫，例如美国杜邦公司研制出一种新型复合材料聚对苯二甲酰对苯二胺，并以"Kevlar"作为其商标。这是一种芳烃聚酰亚胺纤维，众所周知芳烃聚酰亚胺纤维难以染色，而且在高温下酸性环境中会发生分解，因此如何改善疏水亚胺纤维染色亲和力，在保证纺织品高升华、水洗摩擦牢度的同时，赋予亚胺纤维鲜艳色彩和柔软手感，同时避免高浓度色水产生成为行业中重点研究的课题。

（2）复合布料送至恒温烘箱中进行化学反应，达到固色增色效果，烘干温度控制在140℃；
（4）烘干后进行汽蒸，汽蒸温度为160℃~210℃，汽蒸时间为5~30分钟；
