新型低温皂洗剂A在棉针织色布上的应用

Application of soaping agent A to reactive dyeing of cotton knits at low-temperature

采用低温皂洗剂A对染色纯棉针织物进行皂洗处理,探讨了低温皂洗剂A用量、皂洗温度、时间、pH值和染料类型等工艺因素对皂洗脱色率和皂洗牢度的影响。优化的皂洗工艺为:低温皂洗剂A 3 g/L,60℃皂洗20 min。,低温皂洗工艺与常规皂洗工艺相比,皂洗织物的色牢度相当,且前者色光变化小,皂洗残液无色透明,节能减排效果显著。

Soaping is carried out to the reactive dyeings with low-temperature soaping agent A.Effect of technological factors on soaping are analyzed,such as dosage of low temperature soaping agent A,soaping temperature and time,pH value and reactive dyes type on color fastness to washing.The optimum process is obtained as follows: soaping at 60 ℃ for 20 min with low temperature soaping agent A 3 g/L.Compared with traditional soaping process,the new low-temperature soaping process features similar color fastness,less shade change,and lower energy consumption.
