Description
技术领域
本发明属于织物印染处理技术领域，具体涉及一种混纺织物印染前处理的连续生产工艺。
背景技术
现有技术中，纺织品印染前处理的炼漂过程包括退浆、精炼和漂白三道工序，分别在三个独立的过程中完成，这种工艺的主要缺点是：工序繁复，设备流水线长，耗能大；作业时间长，对织物的纤维损伤大；工作液中含有大量的烧碱、漂白剂、稳定剂等，排放的废水毒性大、环境污染严重，处理难度高。
目前，最常使用生物酶实现一浴法前处理工艺，生产过程退浆、精炼和漂白在同一处理浴中完成，其生物酶采用淀粉酶、果胶酶、脂肪酶、蛋白酶、纤维酶，各生物酶单独或若干种混合使用，并采用次氯酸钠、亚氧酸钠等组成的漂白剂，处理浴中还加入氯化钠、硫酸钠等稳定剂和聚氧乙烯烷基醚类组成的表面活性剂等，这种工作液由各种不同的生物酶、漂白剂、表面活化剂和稳定剂组成，成分复杂，对不同的纤维要根据不同的特征调整合适的助剂组成及其配比，而且操作过程是间歇式的，在不同的生产阶段，根据需要不断的改变助剂，不能实现连续生产。
故，需要一种新的技术问题以解决上述问题。
