减少棉/毛混纺织物在后整理中羊毛纤维的损伤

Discussion on cotton/wool blended fabric reducing the wool fiber damage during its dyeing process

棉纤维不耐酸,染色加工需在碱性条件下进行,而羊毛纤维不耐碱,染色加工是在酸性条件下进行,2种纤维的加工环境相互矛盾。文章研究了在羊毛纤维不耐碱、棉纤维不耐酸这2种矛盾的纤维特性中,如何解决染同色时羊毛纤维的损伤问题,从而为消费者提供一种兼具2种纤维优良性能的棉/毛混纺面料。就棉/毛混纺面料从退浆、煮练、漂白到染色整个工艺过程,如何有效地减少羊毛纤维的损伤,进行了深入研究和探讨,尤其对前处理助剂的选用及染料的选择作了较为详细的论述。

Wool fiber is not acid-resitant, cotton fiber is not alkali-resitant, it is difficult to dye cotton/wool blended fabric in one bath. In this paper, it studied how to resolve the problem of wool fiber damage in dyeing process. It researched the whole process from desizing, boiling, bleaching and dyeing for the cotton/wool blended fabric. The selection of pre-disposal agent and dyestuff was discussed in detail.
