Polysulfide Crosslinked Cotton by Reaction of Chlorodeoxycellulose with Ethylenediamine Hydrosulfide

Abstract

Cotton fabrics with polysulfide crosslinks were prepared by reacting chlorodeoxycellulose with ethylenediamine hydrosulfide in ethylenediamine at 54–100°C. The polysulfide fabrics had good wet wrinkle resistance (280°) and strength retention (above 65%). Oxidation of the crosslinked fabrics with hydrogen peroxide did not adversely affect these textile properties. The effect of reaction time and temperature, hydrosulfide concentration, reaction solvents, method of treatment, and degree of substitution of chlorodeoxycellulose on the strength and wrinkle resistance of the polysulfide crosslinked fabrics was determined.
