Cotton fabrics were pregrafted with a mixture of N ‐methylolacrylamide and methacrylic acid at mixing molar ratio of 4/6. The influence of pregrafting on the kinetics of finishing with 1,3‐dimethylolethylene urea was studied. The results shows that pregrafting can increase the rate constants. Values of E a Δ H * , Δ S * , and Δ G * suggest that the pregrafting of cotton fabric not only affects the reaction action state, but also is beneficial for the reaction between cellulose and the finishing agent. © 1996 John Wiley & Sons, Inc.
