纯棉织物福来隆WH型活性染料浸染工艺

Exhaust dyeing of cotton fabric with Fulairon WH reactive dyestuff

福来隆WH型活性染料是在双活性基团活性染料的基础上优化改进的一类活性染料，其反应性好，固色率高。文中对这类染料浸染工艺的上染率，染色工艺参数[如染色、固色温度和时间、电解质（元明粉）]，碱剂用量和浴比等进行试验。结果表明，福来隆WH型活性染料具有良好的拼色配伍性，当元明粉用量40～60g/L，纯碱用量10～20g／L，浴比1：10—1：30，60℃染色30min，80℃固色40～60min，染品可获得很深的色泽。在实际生产中，上染和固色常采用60℃恒温工艺，以便工艺控制。

Fulairon WH reactive dyes with bi-functional reactive groups feature good reactivity and high fixation rate. In this paper, exhaust dyeing process of cotton fabric with Fulairon WH reactive dyes was carried out, factors impacting on dye yields were discussed, such as temperature and time in dyeing and fixing, dosages of electrolyte and alkali, as well as bath ratio. Results showed that, the dyeings could achieve deep shade with Na2SO4 40- 60 g/L, Na2CO3 10 - 20 g/L, bath ratio 1 ： 10 -1 ： 30,dyeing at 60 ℃ for 30 minutes and fixing at 80℃ for 60 minutes. Fulairon WH reactive dyestuffs had good compatibility. In practical production, dyeing and fixation temperature were normally kept at 60℃ for easy process control.
