Abstract
AbstractSoiling of textiles is an irresistible process that deteriorates the appearance of fabric caused by gradual accumulation of soil on it. Cotton fabrics were finished with two different types of soil releasing agents, viz. Oleophobol CPR (fluorocarbon based) and Carboxymethyl cellulose sodium salt (CMC-Na) using Box-Behnken and Full factorial designs, respectively and the effect of factors and their levels on soil release property of fabric was studied. Finished fabrics were tested for two different soils i.e., mustard oil and hot coffee. From soiled and laundered fabrics soil release was evaluated for soil release rating as well as instrumental prediction with K/S value to measure discolouration of fabric due to soil. The CMC-Na salt finished cotton fabric picked up significantly more soil compared to that with Oleophobol CPR which resisted deposition of soil on fabric. Cotton fabrics finished with both of these showed excellent soil release with mustard oil and had better finish durability with Oleophobol CPR. Physical properties were comparable except stiffness which was high in CMC-Na finished cotton.
