A study has been made of the reaction products of hydroxymethylated 2‐substituted (X) 4,6‐diamino‐ s ‐triazines (MXT) with cotton fabrics in the presence of zinc nitrate as catalyst. The reagents used were MXT having the following substituents: methoxy (MMT), isopropoxy (MIPT), methyl (acetoguanamine) (MAG), monoethylamino [N‐(2‐ethyl)melamine] (MEM), monohydroxyethylamino [N‐(2‐hydroxyethyl)melamine] (MHEM), and dihydroxyethylamino [N,N‐bis(2‐hydroxyethyl)melamine] (MBHEM) groups. Trimethylolmelamine (TMM), dimethylolurea (DMU), dimethylolethyleneurea (DMEU), and dimethylolethyltriazone (DMET) were also used for comparison. The molar ratio of total formaldehyde to 2‐substituted 4,6‐diamino‐ s ‐triazine (XT) residue in treated fabrics is larger in high‐temperature curing than in low‐temperature curing. In case of curing at 150°C for 5 min, MHEM and MBHEM crosslinked primarily with cellulose in a monomeric state, and the others in a oligomeric state. From these facts, the crosslinked structures were presumed. Infrared absorption spectra of the fabrics treated with MXT are discussed and a few physical properties of the fabrics are compared with those of the fabrics finished with TMM, DMU, DMEU, and DMET.
