摘 要: | 为推进棉针织物平幅冷轧堆工艺,将新型复合低温漂白活化剂棉丽净DZ-1应用于棉针织物冷轧堆前处理工艺,通过考察棉丽净DZ-1、NaOH质量浓度、H2O2质量浓度、堆置温度对织物白度的影响,优化前处理工艺条件;将漂白后的织物用雅格素CBM型活性染料进行冷轧堆染色,并与传统浸渍染色对比。结果表明:经棉丽净DZ-1冷轧堆前处理的织物白度和润湿性与传统高温前处理工艺、常规冷轧堆前处理工艺相当,但强力损失明显减小;在相同雅格素CBM型活性染料用量下,不同前处理棉针织物半制品冷轧堆染色效果基本一致,表观色深和固色率均高于浸染。

Cold pad-batch pretreatment and dyeing of cotton knits |
| |
Abstract: | In order to promote open-width cold pad-batch process of cotton knits, a novel low temperature bleaching compound additive Texbleach DZ-1 was applied to cold pad-batch pretreatment process of cotton knits. Influences of the dosage of Texbleach DZ-1, caustic soda, hydrogen peroxide andbatching time on fabric whiteness were studied and the optimized process conditions were determined. Then cold pad-batch dyeing of bleached fabric was carried out with Argazol CBM reactive dyes. The results showed that the whiteness and wettability of fabric treated by cold pad-batch pretreatmentusing Texbleach DZ-1 is similar to those by conventional high temperature and conventional cold pad-batch pretreatment process, while the strength loss is obviously reduced. Under the same dosage of Argazol CBM reactive dyes, the fabric dyed by cold pad-batch dyeing processhas the same yield color, fixation and fastness, which pretreated by the above three different kinds of pretreatment processes, it shows the improvement of color depth and fixation of cotton knits dyed by cold pad-batch dyeing method compared with exhausted dyeing method. |
