ABSTRACT:
Wet and dry crocking are reduced on dyed textile cellulosic materials and their blends by aftertreatment with finish mixtures containing effective amounts of a reactive polyamine component and a blocked urethane prepolymer component. The polyamine component is a polyamide, epoxidized polyamide, chain-extended polyamide, epoxidized chain extended polyamide, epoxidized polyamine or epoxidized polyalkylenimine and the blocked urethane prepolymer component is a reaction product of excess polyisocyanate and hydroxy terminated polyether or hydroxy terminated polyester whose reactive isocyanate groups are blocked. Finish mixtures are applied to the dyed textile material, dried and cured to improve wet and dry crockfastness.
