Worldfast DF 2078 designed by us, increases fabric quality and wet colorfastness. The fabric has unfixed dyestuff on the surface after the dyeing process, which causes color migration while wet or after washing if it becomes finished items. To fix the unfixed dyestuff on dyed cloth, a fixing agent must be used. Worldfast DF 2078 is ideally suited for use as a fixing procedure following the rinse stage to prevent Direct and Reactive dye bleeding. This agent is very cost-effective and widely appreciated by our clients.
Worldfast DF 2078 is formaldehyde condensate dye fixing agent to improve wet fastness in the process of direct and reactive dyed cellulosic material.
