Dyeing and stiffness characteristics of cellulose-coated cotton fabric

Abstract

In this study, the effect of cellulose coating on dyeing and other properties of cotton fabric was investigated. Three different reactive dyes were used for dyeing coated cotton fabric. The effect of cellulose coating on the dyeing properties of cotton fabric was studied by determining the K/S values of coated substrate at different concentrations of cellulose and dye. The K/S value decreased by 40–60 % with increasing coating concentration of cellulose from 0 to 5 %. The results show that the stiffness was increased from 0.16 to 2.50 N/m by coating of cellulose on the surface of cotton fabric. The stiffness was permanent as confirmed by ten multiple washings. Mechanical properties remained excellent. X-ray diffraction analysis showed that the amount of cellulose II increased slightly after solvent treatment. Fastness properties of cellulose-coated cotton fabrics against rubbing, washing, and perspiration were good.
