ABSTRACT

Desizing and scouring of cotton fabric was performed with conventional chemical and enzymatic methods. Three enzymes viz., acid cellulase, neutral cellulase, and xylanase were applied on the scoured fabric to enhance the dyeing and functional properties. The dyeing of the enzyme treated fabrics was performed with Acacia catechu. The chemicals constitution of the dye was analyzed by phytochemical and FTIR method. The color values, fastness, mechanical, and functional properties were evaluated as per standard testing methods. The phytochemical analysis indicated the presence of saponins, flavonoids, glycosides, phenols, and terpenoids in the dye. The color uptake was better in enzyme pretreated fabric than chemically pretreated fabric. The fastness properties of the dyed fabric were found to be good. The dyed fabrics showed excellent UPF and antimicrobial properties against gram +ve and gram -ve bacteria. Among the three enzymes, the performance of xylanse enzyme was found to be superior to others.

摘要

棉织物的退浆和煮练是用常规的化学和酶促方法进行的。将三种酶，即酸性纤维素酶、中性纤维素酶和木聚糖酶应用于经过洗涤的织物上以增强染色和功能特性。酶处理织物的染色是用儿茶相思进行的. 采用植物化学法和FTIR法分析染料的化学成分。根据标准测试方法评估色值、牢度、机械和功能性能。植物化学分析表明染料中存在皂苷、黄酮类化合物、糖苷、酚类和萜类化合物。酶预处理织物的上色性优于化学预处理织物。发现染色织物的牢度性能良好。染色织物表现出优异的 UPF 和抗革兰氏 +ve 和革兰氏 -ve 细菌的抗菌性能。在这三种酶中，发现木聚糖酶的性能优于其他酶。
