Abstract

N-Ethyl-N-(2-chlorciethyl)aziridinium chloride, the water-soluble intermediate formed from N-ethylbis(2-chloroethyl)- amine, was found to be sufficiently stable to allow bake-cure as well as wet-cure crosslinking of cotton. An examination was made of the effects of wet-cure (25°C) vs bake-cure (120°C and 140°C) crosslinking upon the structures of the reagent residues (i.e., the fractions of simple substituents, simple crosslinks. and complex structures) and upon the sites of attach ment of reagent residues to the glucose units of the cellulose chain. The fraction of simple crosslinks was similar in products of both wet- and hake-cure reactions; however, the fraction of simple substituents was higher and the fraction of complex products was lower in the cotton modified by bake-cure reactions. The predominant crosslinks in all cases were those with 2,6'-O-linkages (i.e., from the hydroxyl at C-2 in one glucose unit to the hydroxyl at C-6 in another glucose unit).
