Abstract

A new method to produce good durable press of cellulose fibres has been found, to replaces the most effective , but possible harmful formaldehyde adducts of urea which release formaldehyde during the production and wearing of clothes. This method involves the direct esterification of hydroxyl groups of cotton with polycarboxylic acids (PCA). PCA with three or more carboxylic acid groups can crosslink hydroxyl groups of cellulose and form stabile ester bonds. Esterification proceeds at higher temperature but can be accelerated by the salts of weak acids. The most promising catalyst in cotton fibre crosslinkig is sodium hypophosphite. Results from our research show that the chosen polycarboxylic acid, BTCA; is less effective than conventional formaldehyde adduct of urea, but with the optimisation of finishing process it is possible to increase the effectiveness of BTCA as a crosslinking reagent. The aim of our research is to study crosslinking reagents with different formaldehyde content (high, medium, low or formaldehyde free) regarding to formaldehyde release and regarding to the best durable press finishing performance.
