本发明公开了一种羊毛面料的抗起毛整理方法，包括减法还原、聚氨酯预聚体的合成和加法整理步骤。该羊毛面料的抗起毛整理方法通过三羧乙基膦还原破坏羊毛纤维鳞片层，促使二硫键温和地还原为巯基，将合成的粘度较低的聚氨酯预聚体形成薄膜包覆纤维表面，结合减法处理和加法处理，改善羊毛面料的抗起毛效果。

Description

一种羊毛面料的抗起毛整理方法
技术领域
本发明涉及面料抗起毛技术领域，具体涉及一种羊毛面料的抗起毛整理方法。
背景技术
羊毛面料的抗起毛起球的方法主要包括两大类，加法处理和减法处理，前者是指通过一定的方法将聚合物沉积在纤维表面，从而减少羊毛纤维表面的摩擦效应；而后者是指利用一定的化学方法将纤维表面的鳞片层剥落，进而提高羊毛的防毡缩效果。
减法处理的缺陷在于织物泛黄以及处理过程使用大量的化学试剂，基于环保角度考虑，工业废水的处理难度大。加法处理的羊毛织物能够确保良好的防毡缩性能和耐洗性，但纤维之间抱合力较差，容易在服装表面形成毛羽，影响织物的美观和服用性能。
发明内容
本发明的目的在于克服现有技术中存在的缺陷，提供一种羊毛面料的抗起毛整理方法，将现有的减法处理和加法处理相结合，达到抗起毛效果。
为实现上述目的，本发明的技术方案为：一种羊毛面料的抗起毛整理方法，其特征在于，包括以下步骤：
S1：将羊毛精纺面料置于乙醇溶液中清洗处理，烘干；
S2：将S1所得羊毛面料直接转移至还原液中，绝氧反应2～4h后，水洗烘干，还原液的主要组分为与水混溶的醇溶剂、三羧乙基膦、水和pH值调节剂，所述还原液的pH值范围为6.5～7.5；
S3：合成聚氨酯预聚体，将5重量份的异氰酸酯、8～10重量份的聚多元醇和0.1～0.3重量份的催化剂混匀并置于65～85℃下反应2～5h，然后降温至35～55℃向反应体系中加入具有羟基的0.5～1重量份的扩链剂，继续反应1～3h，加入2000～2500重量份有机溶剂得聚氨酯预聚体分散液；
S4：将S2所的羊毛面料浸渍于S3所得聚氨酯预聚体分散液中，加入三乙胺反应0.5～1h，低温烘干，得抗起毛的羊毛面料。
优选的技术方案为，S3中异氰酸酯为选自二苯基甲烷二异氰酸酯、4 ,4 '-二环己基甲烷二异氰酸酯、甲苯二异氰酸酯、异佛尔酮二异氰酸酯、六亚甲基二异氰酸酯中的一种或两种以上的组合，所述多元醇为选自聚丙二醇和/或聚乙二醇。
优选的技术方案为，还原液中水和醇溶剂的体积比为1：（4～6），三羧乙基膦的浓度为15～30mol/L。
优选的技术方案为，所述催化剂为二月桂酸二丁基锡，所述扩链剂为2,2-二羟甲基丙酸。
本发明的优点和有益效果在于：
该羊毛面料的抗起毛整理方法通过三羧乙基膦还原破坏羊毛纤维鳞片层，促使二硫键温和地还原为巯基，将合成的粘度较低的聚氨酯预聚体形成薄膜包覆纤维表面，结合减法处理和加法处理，改善羊毛面料的抗起毛效果。
