活性染料染色一次成功的探讨

Study of Dyeing Success in One Time by Reactive Dyes

为解决小样到大生产染色重现性差的问题,以大生产的Sumifix Supra染料染色工艺为例,采用具有自动加碱的Mathis Datex future NT染色小样机进行染色,利用分光光度仪以染色大样为标准对染色小样进行测试分析。针对染料上染的特点,测试并分析了染色温度、保温时间对小样颜色的影响,进而对染色工艺进行修正。结果表明,通过对小样染色工艺的分析、修改,最终达到小样与大生产颜色一致的目的,可以快速、准确地取得大生产染色配方;染色一次成功率可达93%。

In order to solve the problem of poor reproducibility in the dyeing from sample to large-scale pro-duction, taking the large-scale production dyeing process of Sumifix Supra dyes as an example, fabric was dyed by Mathis Datex future NT dyeing sample machine with automatic alkaline and the dyeing samples were tested and analyzed by spectrophotometer with the dyeing bulk sample as a standard. According to the characteristics of the dyeing, the effects of dyeing temperature and holding time on the color of samples were tested and analyzed, and the dyeing process was corrected. The results show that the color of sample and large-scale production can be the same through analyzing and correcting the dyeing process, and it can rapidly and accurately obtain the dyeing recipe of large-scale production; dyeing success in one time can reach 93%.
