棉织物活性染料丙酮/水体系染色
|
摘要
棉织物用活性蓝RB160在丙酮/水体系中染色,分析了丙酮体积分数、染色温度、染色时间、预处理碱液质量浓度对染色性能的影响,并与传统水浴的染色效果进行了比较。结果表明:丙酮/水体系中丙酮体积分数达到90%时,染料基本吸尽,固色率达到最大值;升高温度有利于提高染料的固色率;预处理碱液质量浓度为10 g/L时,固色率最高;与传统水浴80℃染色效果相比,60℃丙酮/水染色体系在无电解质促染情况下,染料上染率明显提高,染色织物的K/S值和固色率提高,染色织物的均匀度和色牢度均达到传统水浴染色的效果。
The cotton fabrics were dyed using the Reactive Blue 160 in the acetone/water system, followed by analysing the effects of the parameters, including the volume percentage of acetone, dyeing temperature, dyeing time and the concentration of NaOH in the pre-treatment, on the dyeing properties. The dyeing effects were compared with the effects in the traditional water dyeing. The results showed that the exhaustion and fixation rate reached the maximum value in the acetone/water system with 90% of acetone and 10 g/L of NaOH. The increasement of the dyeing temperature facilitated the improvement of the fixation rate. Compared with traditional water bath dyeing at 80 ℃, the dye-uptake rate, the K/S value and the fixation rate significantly improved in the acetone/water system dyeing at 60 ℃ without the addition of electrolyte to promote the dyeing process. The levelness and colourfastness of dyed fabrics in acetone/water system presented a same level with the results which were dyed in the conventional water dyeing process.
