Description and Uses
1,2,3,4-Butanetetracarboxylic acid (BTCA) is a perfect formaldehyde-free durable press (DP) finishing agent. It has high activity of reaction and no irritant odor.It is used as cotton, hemp, silk and other cellulosic fibers, anti-wrinkle and anti-shrink agent, with the finishing agent for fabric finishing, can improve the shaping effect and the fabric does not contain formaldehyde.
BTCA, catalyzed by sodium hypophosphite (SHP), brings good antiwrinkle property to cotton fabrics and causes significant strength losses due to cross-linking and acidic degradation of cellulose simultaneously.
