摘要
由于聚乳酸纤维属于脂肪族聚酯,具有与PET相同疏水性及熔点较低、不耐高温和强碱的特点,因此采用低碱退浆、分散染料染色的染整工艺。文章介绍了实验材料聚乳酸纤维(PLA)仿毛机织物的烧毛、退浆、练漂、热定形、染色的工艺参数和染整加工中的加工要点及注意事项,着重分析了pH值、染色时间、染色温度对上染率的影响,并得出最佳的染色工艺参数:染色pH值5,温度110℃,时间35 min。
Dyeing and finishing process of low alkali desizing, disperse dyes dyeing are adopted in this paper because polylatic fiber（PLA） belongs to aliphatic polyester fiber with low melting point, non-endurance to high temperature and alkalia and possesses the same ability in non-adopting water with PET. The experimental material in this paper is polylatic fiber （PLA） imitative wool fabric moven. This article introduces the technique parameters of singeing, desizing, bleaching, thermal stability and dyeing as well as machining point attention proceeding, at the same time it mainly analyses the influence of pH value, dyeing time and dyeing temperature on dye uptake, moreover, optimum technique parameters are elected：pH value 5, dyeing time 35 min, dyeing temperature 110 ℃.
