纯棉毛巾织物煮漂增白一浴法工艺

Scouring,Bleaching and Fluorescent Brightening of Cotton Towel Fabrics with One Bath Process

为解决纯棉毛巾织物传统煮漂与增白工艺两浴法加工能耗大、工序长等问题,文中采用煮漂增白一浴法对纯棉毛巾织物进行处理,探讨了多功能精练剂DM-1337、H2O2、NaOH、荧光增白剂VBL等对处理效果的影响,优化煮练增白一浴法工艺,并与传统煮练、增白两浴法工艺进行对比。结果表明,优化的纯棉毛巾织物煮漂增白一浴法工艺为:多功能精练剂DM-13374.0g/L,30%双氧水20mUL.NaOH1.0g/L,荧光增白剂0.3g/L,浴比1:20,煮漂增白一浴法处理后织物白度为97.3%,沉降时间为5.8s,与传统两浴法工艺处理效果相当,强力损失率明显降低;煮漂增白一浴法生产实践效果和传统两浴法工艺相当,且缩短了工艺流程、提高了生产效率,降低能耗,具有明显的节能减排效应。

Cotton towel fabrics were pretreated and fluorescent brightened with one bath process to solve the problems such as energy consumption,multi-step operations in traditional two bath process.The influences of concentration of multi-function scouring agent DM-1337,H2O2,NaOH,fluorescent whitening agent VBL on the treatment results were explored,and the pretreated and fluorescent brightened one-bath process was optimized,which was compared with the traditional two-bath process.The results show that the optimal one bath process of pre treatment and fluorescent brightening of cotton towel fabrics is as follows:4.0 g/L of multi-functional scouring agent DM-1337,20 mL/L of 30%hydrogen peroxide,1.0 g/L of NaOH,0.3 g/L of fluorescent whitening agent VBL,and bath ratio 1:20.The whiteness and sedimentation time of the treated fabric were 97.3%and 5.8 s,which were similar to the traditional two bath process,and the strength loss ratio was obviously reduced.The practice effect of pretreated and fluorescent brightened one bath process is equivalent,but with an energy consumption reduction,which has obvious effect of energy saving and emission reduction.
