An estimation of structures of reagent residues in cotton fabrics treated with N ‐methylolmethacrylamide (NMMA) and N ‐methylolacrylamide (NMA) and comparison of textile performance of the NMMA–cotton and NMA–cotton provide the basis for insight into the structure–performance relationship in these fabrics. The α‐methyl substituent, which constitutes the difference between NMMA and NMA, accounts for an altered composition of reagent residues in the treated cotton. The more attractive balance of strength–abrasion resistance with resilience for the NMMA–cotton seems to be a result of a lower degree of covalent crosslinking, which appears compensated by a higher elastic modulus in the NMMA network polymer.
