Cotton fabric was biopolished using free and immobilized cellulase. The immobilized cellulase treatment results lower weight loss and minimum reduction in tensile strength of the fabric at the minimum of 67% and a maximum of 98.35% and better whiteness index when compared with free cellulase treatment. Regression analysis was carried out for all properties, regression coefficients and summary of fit have been discussed. Both free and immobilized cellulase treated fabrics showed improved crystallinity index and it was analyzed by XRD. FTIR spectra were obtained to measure the hydrogen bonding intensity, which showed that the intensity values were decreased after treatment. The study confirms that the treatment with immobilized cellulase improves the surface properties without affecting the strength of fabric than the fabric treated with free cellulase.

使用游离的和固定的纤维素酶对棉织物进行了生物抛光。与游离纤维素酶处理相比，固定化纤维素酶处理的重量损失更低，织物的抗张强度降低最小，最小为67％，最大为98.35％，并且白度指数更好。对所有属性进行了回归分析，讨论了回归系数和拟合摘要。游离的和固定的纤维素酶处理的织物均显示出改善的结晶度指数，并且通过XRD对其进行了分析。得到的FTIR光谱用于测量氢键强度，表明处理后强度值降低。
