反应性直接染料的应用性能

近年问世的反应性直接染料,染色程序简短,染深性好,与直接染料很相似.其在碱性浴中能与纤维素纤维发生交联固着,染后只需水洗、皂洗,染色湿牢度优秀,也与活性染料相似.反应性直接染料特别适合纯棉(粘胶)织物染色,尤其适合纯棉针织物深浓色泽练、洗、染—浴一步法染色,生产效率高,且有节能减排优势.

Practical performance of reactive direct dyes

The reactive direct dye featuring short dyeing process and good dye depth,is very similar to direct dyes.This kind of dyes can crosslink with cellulose fiber and fix on it in alkali bath,with washing and soaping process just after dyeing,and excellent wet color fastness,which in turn is similar to reactive dyes.It is particularly suitable for cotton(viscose) fabric dyeing,especially for the process of scouring,washing and dyeing in one bath and one-step of cotton knits in deep shade.It has very broad applic...
