纯棉织物活性防活性印花

Reactive resist reactive dye printing of cotton fabric

介绍纯棉织物以KN型活性染料染底,但不固色,再以K型活性染料印花入色的活性防活性印花工艺。利用KN型与K型活性染料的活性和稳定性不同,选用能与KN型反应,而不与K型活性染料反应的防染剂HW S,防止KN型染料与纤维结合,起到防染作用。通过生产实践,给出了该工艺的工艺条件和加工要点。

Ground dyeing with KN type reactive dye and non-fixation on cotton fabric, and then printing with K type reactive dye are introduced, To make use of the differences of activity and stability between KN type and K type reactive dyes, the resist agent HWS, which can react on KN type dye and cannot react on K type dye, is selected, so as to prevent KN type dye combining with the fiber, Based on production practice, the process condition and main points are presented.
