Improving the Breaking and Tear Strength of Cotton Fabric Using BTCA and CA Crosslinkers

Abstract

Polycarboxylic acids are used as crosslinking agents with sodium hypophosphite which do not containformaldehyde. In this study, breaking strength, breaking elongation and tear strength of cotton(twillweave)fabric samples were determined by using twill fabrics, six different coating recipes, produced with100% cotton yarns. The results of breaking strength, breaking elongation and tear strength testing werecompared according to the fabric structure, coating recipes and crosslinker structure statistically. Asignificant increase in tensile strength was observed after coating with 1g Cu2O|<5 ?m, CuO<5 ?m,ZnO<5 ?m and 5 g 1,2,3,4-BTCA. The high number of warp threads per unit length in cotton wovenfabric leads to an increase in tensile strength. The best results in tensile strength and elongation at breakexperiments were obtained after the reaction of polyacrylate binder with BTCA and ZnO microparticles.
