摘　　要：为进一步提高单一酶对棉织物的精练效果,复合生物酶精练日益受到重视。但由于不同酶制剂最佳工作条件的不一致,使复合酶精练受到极大限制。为此,研究了自制碱性果胶酶、中性纤维素酶、中性碱性蛋白酶和自制木聚糖酶及其组成的复合生物酶制剂的棉针织物一浴一步法精练加工工艺,确定了最优精练组合。结果表明,复合酶的精练效果较单一酶有明显的提高,织物润湿性、染色性能接近常规碱精练水平且强力损失更小。In order to improve the enzymatic scouring effect, compound enzymes have received growing attention. However, the optimal scouring conditions vary with enzyme preparation, which has greatly limited the application of compound enzymes. Therefore, one-step one-bath scouring of knitted cotton fabrics with home- made alkaline pectinase, neutral cellulose, neutral-alkaline protease and xylanase as well as their combinations was investigated in the present work. The enzyme combinations for cotton scouring were optimized. The results showed that compound enzymes scouring exhibits better effect than individual enzymes, and wettability and dyeing properties that are very close to the conventional scouring but less strength loss.
