- Abstract
Finishing cotton fabrics with polycarboxylic acid crosslinking agents in combination with nitrogenous additives was investigated as a means of introducing dyeability into the smooth drying textiles. Substantial improvement in the dyeing properties of the modified ester-crosslinked cotton was obtained by using various hydroxyalkyl nitrogenous compounds as additives. The most effective was triethanolamine (TEA), both as the free amine and as the amine hydrochloride. Cellulose finished with a polycarboxylic acid, such as butanetetracarboxylic acid (BTCA), has some affinity for cationic (basic) dyes. However, because of chemical and physical modification of the fibers, the finished material has virtually no affinity for anionic dyes that are normally used to dye cotton. In contrast, cotton finished with a polycarboxylic acid and certain amine derivatives has good affinity for some anionic dyes. Cotton treated with this modified finishing system can be dyed with acid, direct and reactive dyes under specific dyeing conditions. Methods for producing dyeable, nonformaldehyde crosslinked, smooth drying cotton, as well as color strength properties of the dyed fabrics are presented.
