Study of Chemical Treated Cotton Fabric for functional Finishes using Chitosan

Jeyakodi J. Moses

Abstract


Cotton fabrics were treated with sodium hydroxide, morpholine and cellulase enzyme. These treated cotton fabrics were applied by chitosan followed by dyeing with some selected dyes such as annatto, onion, pomegranate, indigo, myrobalan, bar berry (natural dyes); and reactive and Sulphur dyes (synthetic) respectively. These treated samples were tested for different functional properties such as, wicking, water vapor & air permeability, K/S value, fastness properties, antimicrobial property, and SEM analysis. Results show that chitosan treatment imparts functional properties on cotton fabrics. Among all the treated fabrics, sodium hydroxide treated cotton fabric revealed higher values.
