Soaping Agent for Reactive Dye (After-Treatment)
A high-performance nonionic soaping agent specially formulated to remove unfixed reactive dye and hydrolyzed dye from cotton fabric after dyeing. It prevents back-staining of the dyed fabric during the soaping wash and achieves high wet fastness standards in a single soaping step at 95°C. Suitable for all reactive dye classes including vinyl sulfone and MCT types.
