초록

This study examined the use of cutinase and lipase to process cotton/polyester blend fabric. Optimum treatmentconditions for cutinase and lipase were investigated for cotton/polyester blend fabric. The properties ofenzyme-treated fabrics were evaluated and compared in optimal treatment conditions. In addition, the possibilityto provide an enzymatic finishing on blend fabrics using mixed enzymes in a two-step process were studied. The weight loss of cotton/polyester blend fabrics with Triton X-100 was 0.8% and the dyeing property of blendfabrics with calcium chloride increased by a factor of 1.2. The use of two enzymes in combination with cutinaseand lipase in the presence of auxiliaries resulted in a cotton/polyester blend fabric weight loss of 0.8%. In addition,the dyeing properties of cotton/polyester blend fabrics improved by a factor of 1.5 and the moisture regainof cotton/polyester blend fabrics improved by a factor of 1.16. However, no marked loss was observed intensile strength. The surface morphology of cotton/polyester blend fabrics is modified through a two-enzymetreatment. The treatment of cotton/polyester blend fabrics with cutinase and lipase maintains cotton strengthand improves the moisture regain of polyester fabrics.
