The nature of the interaction of trimethylolmelamine resin with cotton substrates, arising from the dry curing (ca. 140° C for 4 min) of the resin on cotton, has been in vestigated. A new chemical analytical method is described for the elucidation of the chemical structure of the resin-treated cottons. It is expected that this method will constitute the basis of a general method for the chemical structural analysis of resin- treated celluloses. Data are presented which show cheruical evidence for covalent bonding of the resin to cellulose and that some of the cellulose hydroxyl groups at each position, i.e., C6, C2, and C3, are involved in resin substitution (C6 > C2 > C3). The presence of interchain cross links is indicated. The results also indicate lower DS than anticipated from the resin content of the treated cottons analyzed.
