The behaviour towards wet transfer printing of cationized and aminized cottons having different nitrogen contents before and after crosslinking was studied. Cationization was effected through reaction of cotton with (3-chloro-2-hydroxypropyl)trimethylammonium chloride whereas aminization was achieved by reacting cotton with 2-chloroethyl diethylamine hydrochloride.The modified cottons were crosslinked using polycarboxylic acids, namely citric acid and 1, 2, 3, 4 – butane tetracarboxylic acid, followed by wet transfer printing using alginate films containing either a reactive dye or a direct dye without using electrolytes. Prints on cationized and aminized cottons exhibited significantly higher colour strength than on the untreated cotton. Crosslinking of the cationized and aminized cottons prior to wet transfer printing detracted much from their greater amenability to such printing. The wash, rub and perspiration fastness values of the reactive dye on cationized and aminized cottons before and after crosslinking were found to be comparable or even slightly higher than those for the untreated cotton. However, in case of direct dye, the colour fastness results disclose significant improvement in wash, rub and perspiration fastness over the untreated cotton.
