For improving the wear ability of fabrics, soft finishing to the fabric must be done. There are three kinds of fabric soft finishing, mechanical soft finishing, chemical soft finishing, and bio-soft finishing. This article mainly introduces the definition of biological soft finishing of cotton knitted fabric, test indicators, and the present stage of development at home and abroad. By analyzing the properties and characteristics of cotton fiber and characteristic of cellulose, state the mechanism of biological soft finishing of cotton knitted fabrics. This topic mainly used the orthogonal experimental method, by controlling different reaction temperature, time, and pH value and enzyme concentration to process with a cotton knitted fabric. And test the index of treated fabric whiteness, bursting, wear resistance, thickness, friction coefficient, bending stiffness, shear stiffness. Then analysis the various performance of effect on fabric with temperature, time, pH value and enzyme concentration. Finally found the optimal programmer for biological soft finishing of cotton knitted fabrics. Keyword
