Study the Effect of BTCA Crosslinking Agent on Crease Recovery Angle and Washing Shrinkage Properties of Bleached and Dyed with Bi- and Tri- Functional Reactive Dyed Woven Cotton Fabric

Abstract

Easy care finishing of textile materials is one of textile chemical finishing processes to make cellulosic textile materials crease free and dimensionally stable in its service life or during wear. There are different types of crosslinking agents for easy care finishing of cotton fabric. Among these, 1,2,3,4-buthanetetracarboxylic acid is the most effective and formaldehyde free crosslinking agent. On the other hand, woven cotton fabric treated with reactive dyes to give color to textiles. It reacts with fiber in presence of alkali and forms covalent bond with hydroxyl group of cellulosic fibers. In this study, therefore, investigates the effect of covalent bond formation between reactive dyes and cellulose fiber on crease angle recovery and washing shrinkage percentage properties after treated with BTCA crosslinking agent. Initially, cotton fabric was treated with reactive dyes using cold-pad-batch method and followed by easy care finishing for both bleached and dyed fabric using pad-dry-cure method. The application of Bi- and Tri- functional reactive dyes reduces the total crease recovery angle and Tri- functional reactive dye improves the washing shrinkage percentage properties of cotton fabric.
