摘要
采用淀粉酶和果胶酶复合轧堆的方法对棉织物进行前处理,并与传统的碱处理方法进行对比,处理后的织物分别采用浸染和轧染工艺进行涂料染色,并对上染率、色度值、色差、表观颜色深度K/S、干湿摩擦牢度、皂洗牢度等进行测试.结果表明:(1)生物酶前处理可以达到常规前处理的效果及后续加工的要求;(2)生物酶前处理后织物进行涂料浸染染色时的上染百分率较高;两种方法染色后生物酶处理织物的色深较高,摩擦牢度稍好,皂洗牢度相当.
The cotton was pretreated with the amylase and the pectinase in one bath using the pad-batch process, which was compared with the traditional alkali pretreatment. The treated fabric was dyed with the pigment using dip dyeing and pad dyeing method, respectively. The dye uptake, CIE Lab,△E, apparent color depth K/5,dry and wet crocking fastness,fastness to soaping and so on were evaluated. The results showed that： （1） Pretreated by enzyme had the similar effect to pretreated by traditional alkali, and can achieve the requirement of continuous process （dyeing）; （2） After pretreated by enzyme, the dye uptake dyed by dig dyeing was higher than that of pad dyeing after dip or pad dyeing, pretreated by enzyme had higher color depth, better crocking fastness, similar soaping fastness to those pretreated by the traditional alkali.
