摘　　要：通过分析羊毛织物表面的元素及价态变化,探讨了漆酶-TEMPO生物工艺对羊毛织物表面改性的可能性作用机制和最佳工艺条件.研究发现,漆酶-TEMPO生物工艺对羊毛纤维的氧化作用实现了纤维表面的改性,改善了羊毛织物的表面润湿性,提高染色K/S值,并增强羊毛织物的抗毡缩性能.在pH值为4.5的0.05 mol/L的柠檬酸和0.1 mol/L的磷酸氢二钠整理液中,漆酶用量为每克织物添加使用20 U,TEMPO用量为每克织物添加使用10μmol,织物与整理液间的浴比为1∶20,经45℃振荡水浴处理90 min后,织物表面接触角由130.5°降低至81.7°;染色K/S值从8.41提高至18.43;面积毡缩率从16.37%降低至6.19%.因此,漆酶-TEMPO生物工艺是改善羊毛织物表面性能的一种潜在的绿色染整加工方法.By analyzing the changes of elements and valence states on the surface of wool fabric,the possible mode of action and optimal process parameters of the surface modification of wool fabric by the laccase-TEMPO bio-process are discussed.The result of the study shows that oxidation by laccase-TEMPO bio-process realizes the modification of the fiber surface,improves the surface wettability,increases the K/S value and enhances the anti-felting properties of wool fabric.The optimal process parameters are as follows.For the finishing solution of 0.05 mol/L citric acid and 0.1 mol/L disodium hydrogen phosphate at pH 4.5,the dosage of laccase is 20 U per gram of fabric,the dosage of TEMPO is 10μmol per gram of fabric,and the bath ratio between fabric and finishing solution is 1∶20.After 90 min of oscillating water bath treatment at 40℃,the contact angle of the fabric surface decreases from 130.5°to 81.7°;the K/S value increases from 8.41 to 18.43;the felting shrinkage decreases from 16.37%to 6.19%.Therefore,the laccase-TEMPO bio-process is a potential green dyeing and finishing method of improving the surface properties of wool fabric.
