助染剂处理芳纶纤维的阳离子染色性能探究

Dyeing properties of para-aramid fiber pretreated with dyeing auxiliary

通过对芳纶1414纤维助染剂预处理,进行阳离子染料染色实验,探讨染色工艺参数对芳纶1414纤维染色性能的影响。实验表明,染色最佳工艺为染料用量5%(omf),助染剂用量2%,氯化钠用量15g/L,染浴pH为4.5,染色温度110℃,染色保温时间60min;染色后耐皂洗色牢度可达到4～5级。

Para-aramid fiber was firstly pretreated with dyeing auxiliary, and then dyed with cationic dye. The dyeing technological parameters were explored and the optimized dyeing technological conditions are as follows： dye conce＇ntration 5%（omf）, dyeing auxiliary 2%, sodium chloride 15 g/L, pH of dyeing bath is 4.5, dyeing temperature was kept at 110 ℃ for 60 min. The color fastness to washing can reach 4 -5 grade.
