Improvement of Durable Press Finish Process on Cotton Fabric with 1,2,3,4-Butantetracarboxylic Acid and Chitosan

Abstract

The aim of this research was to improve the durable press finish process on cotton fabric with non-formaldehyde finishing agents. The mercerization of cotton fabric was carried out by 30 Be’ NoOH at 20 C before finishing. The mercerized fabric was finished by padding in the mixture of 4% (w/v) BTCA, 0.4% (w/v) chitosam and 6% (w/v) sodium hypophosphite, then dried at 85 C for 5 min. The treated fabric was cured at 180 C for 3 min. The finished fabric showed wrinkle recovery angle at 262 , tensile strength at 281 N and elongation at break at 34.8 mm. The result showed that the combination of mercerization process and chitosan supported the crosslinking of BTCA on cotton fabric and reduced the loss of tensile strength of finished fabric.
