摘要
在不同pH值、温度和时间的条件下 ,采用不同结构的分散染料对聚乳酸纤维染色。结果表明 ,当pH值为 5时 ,在 1 1 0℃染 30～ 4 0min后聚乳酸纤维能获得稳定的染色效果 ,但需小心控制还原清洗条件 ,否则会造成色相和色深明显变化。通过试验 ,分析了染料结构对聚乳酸纤维染色性能的影响 ,并与分散染料染涤纶 (PET)纤维进行了对比。
Polylatic acid fiber was dyed with disperse dyes of different structures under variable pH value, temperature and time, followed by reductive cleansing. The results showed that the most favorable effects were obtained at pH value 5, temperature 110℃ and time 30～40 min, but the reductive cleansing conditions should be carefully controlled, otherwise it will lead to obviously change in hue and color depth. Influence of the structure of dyestuffs on dyeability of PLA fiber was compared with that on PET fibers.
