生物精练、抛光与活性染料染色一浴工艺

Study of One bath Biological Scouring, Polishing and Dyeing with Reactive Dye Process

文中开发了生物精练、抛光与活性染料染色一浴工艺,介绍了生物复合精练酶在棉针织物精练、抛光与染色一浴工艺的应用,并与常规碱、氧(煮)精练、抛光、染色分步工艺(常规工艺)进行对比,测试了果胶残留率、毛效、强力损失率、抛光效果、CODcr值、耐水洗色牢度,并计算了染化料及能耗成本。结果表明,一浴工艺较常规工艺节约成本,且在生产效率和污水处理方面具有明显优势。

In view of the problems of serious pollution and large consumption of water and electricity in tradi-tional dyeing and finishing processes, this paper developed a one bath biological scouring, polishing and dyeing with reactive dye process. The application of biological compound scouring enzyme in one bath scouring, polishing and dyeing process of cotton knitted fabric is introduced and compared with the conventional process. The pectin residual rate, capillary effect, strength loss rate, polishing effect, CODcr value and colorfastness to washing were tested, and the cost of dyestuffs and energy consumption were calculated. The results show that the one-bath pro-cess has the advantages of cost saving, production efficiency and easy sewage treatment when compared with the conventional process.
