活性染料及酸性染料羊绒染色工艺

在多次实验的基础上给出了活性染料、酸性染料羊绒染色的合理工艺条件,包括染浴pH值、染色温度、助剂用量等,对企业实际生产起到了实际指导作用.实践表明:活性染料染色工艺合理经济,操作简单,各项色牢度特别是湿牢度较高,是取代羊毛纤维用含金属染料的最佳选择之一.酸性染料对蛋白质纤维的亲合力,随染料分子量的增加而增大.根据不同情况可在实际生产中采用强酸浴、弱酸浴和中性浴3种方法染色.

Dyeing process of cashmere with reactive dye and acid dye

This article gives some reasonable dyeing process conditions of reactive dye and acid dye including the pH value,dyeing temperature and builder measure based on many experiments,which make great guidance to practical production of enterprises.Practice indicates that reactive dye is economical dyeing technology,it is easy to operate and has high fastnesses,especially wet fastness,which makes it becomes one of the best choices to replace metallic dye used for wool fiber.The affinity of acid dye to protein fib...
