Abstract

Polyester fabrics were treated with chitosan of various molecular weights and crosslinking agents by the pad-dry-cure method. Chitosan solutions were prepared using acetic acid as a solvent, and the concentration of solution were in the range of 0.l~l%. The properties of the fabrics treated with the chitosan solution, including tensile strength, drape stiffness, reduction rate, and half life, were measured. The strength of the polyester fabrics was observed to decrease greatly by the alkali-treatment, but was recovered by the chitosan treatments. One of the properties obtained with the chitosan treatment was the remarkable antistaticity.
