摘要
低温L型活性染料具有不同于其它活性染料的特殊母体结构,可在低温下固色。优化了染色温度和固色时间,试验结果表明,该染料染色温度可低至40℃,采用复合碱(纯碱5 g/L+烧碱1 g/L)固色,筒子纱各项染色质量指标达到标准要求,节汽节碱,降低了生产成本。
The application performance of low energy L type reactive dye is analyzed. Cotton cheese dyeing with L type reactive dye is carried out, and the dyeing process including dyeing temperature and fixation time, is optimized. The results show that this dye can be carried out at low temperature down to 40℃ and fixed with combined alkali（ sodium carbonate 5 g/L and caustic soda 1 g/L）. The quality of cheese dyeings can meet the standard. The process features low steam and alkali consumption and low production cost.
