摘　　要：选用酸性纤维素酶处理未染色和经过C.I.硫化黑1染料染色的纯棉针织物,通过测定处理后织物的毛羽去除率、质量损失率、织物上的酶吸附量及处理残液中的还原糖含量,分析纤维素酶与织物之间的相互作用并建立动力学方程。结果表明:织物上染料的存在对纤维素酶的吸附具有促进作用,但降低了毛羽去除率;纤维素酶处理染色织物与未染色织物具有相近的米氏常数,分别为51.81和49.97,但未染色织物的最大反应速率约为染色织物的10倍。The acid cellulase was used to treat the undyed and dyed cotton knitting fabrics with C. I. sulfur black 1, the hairiness removal percentage, weight loss of the fabric, the cellulase adsorption on the fabric and the reducing sugar in the residue were determined to explore the interaction between cellulase and fabric to set up kinetic equation. As results, existed dyes in the fabric promoted the adsorption of cellulase to the fabric, declined the hairiness removal percentage; the closed Michaelis constant value of dyed fabric 51.81 and undyed fabric 49.97 obtained. However, the maximum velocity of undyed fabric being almost 10 times of dyed fabric.
