Claim 6
Dependent Claim
62 words
In a process for producing crease-resistant textiles comprising impregnating a textile with a solution of dimethylol dihydroxyethylene urea or a partially or wholly methylated derivative thereof, a catalyst, and a buffering agent and heating the impregnated textile to cure the resulting impregnated textile and impart crease-resistance thereto, the improvement wherein the catalyst is aluminum sulfate and the buffering agent is sodium metaborate.
Claim 7
Dependent Claim
62 words
In a process for producing crease-resistant textiles comprising impregnating a textile with a solution of dimethylol dihydroxyethylene urea or a partially or wholly methylated derivative thereof, a catalyst, and a buffering agent and heating the impregnated textile to cure the resulting impregnated textile and impart crease-resistance thereto, the improvement wherein the catalyst is aluminum sulfate and the buffering agent is sodium metaborate.
