摘要
棉织物活性染料常规染色工艺碱消耗量大,易造成染色不匀、原料浪费、增大废水处理成本;采用低碱活性染料染色是一个重要的解决途径。本文探讨了棉织物HD-LA型低碱活性染料染色的最佳工艺,在染料用量2%(o.w.f.)、食盐60 g/L、碳酸钠5 g/L、固色温度80℃、固色时间50 min、浴比1∶10时,染色效果、能耗均较佳;并与常规活性染料染复色军绿色、咖啡色、灰色的性能进行对比,结果表明:干摩擦、湿摩擦及耐水洗牢度二者基本相似,HD-LA型低碱活性染料染复色匀染性更佳,而碱用量只有传统活性染料的1/2。
There are some problems in traditional dyeing process for cotton fabric with reactive dyes, such as large consumption of alka- li, uneven dyeing, raw materials wasting and cost of wastewater treatment increasing, and the dyeing process with ｜ow-alkali reactive dyestuff is an important solution at present. The optimum dyeing process of HD-LA low-alkali reactive dyestuff to cotton fabric is dis- cussed in this paper. The dyeing effects and energy consumption are the best under the condition of dye dosage 2% （ o. w. f. ）, salt 60 g/L, sodium carbonate 3 g/L, fixation temperature 80 ~C, fixation time 50min, bath ratio 1 ： 6. Compared with the ordinary reactive dyestuff dyeing performance of grass green, coffee color and grey, the dates are shown that dry and wet rubbing fastness and fastness to washing are similar, the level-dyeing property of compound color dyeing is better by low-alkali reactive dyes HD-LA, but 1/2 dosage of alkali to the ordinary reactive dyes.
