纤维素酶处理方式对棉织物性能的影响

Influence of the cellulase treatment method on the textile properties

通过单因素实验,优化酶处理的工艺条件为酶用量2%,pH值5.5,温度60℃,浴比1∶20,时间45min.比较了棉织物用纤维素酶处理后用活性染料和直接染料染色及先染色后用纤维素酶处理,其K/S值、减量率、硬挺度、强力损失率的变化.

The cellulase treatment conditions were optimized by the single factor experiments as cellulase amount 2%, pH 5.5, temperature 60 ℃, liquor ra tio 1:20, and time 45 min. Comparison was carried out for the changes of K/S val ues, weight reduction, stiffness and strength loss in the cellulase treatment fo llowed by reactive and direct dyeing, or in the reactive and direct dyeing follo wed by cellulase treatment.
