| 摘 要： | 针对筒子纱染色涤纶纤维表面杂质问题，从染后纤维的表面杂质含量及主成分含量、染色工艺条件对纤维表面杂质含量的影响、低聚物分散剂和还原清洗助剂对纤维表面杂质的影响3方面进行了试验。结果表明：筒子纱染色涤纶纤维表面杂质大部分为聚酯低聚物，在总杂质中的含量达73%以上；随染料用量增加、染色温度升高和染色时间延长，纤维表面杂质增多；在染浴中加入低聚物分散剂和使用特定还原清洗助剂可大幅降低表面杂质含量。

| Abstract: | In order to solve the surface impurity problems of cheese dyed polyester yarns，experiments were conducted to analyze the effects of dyeing process, oligomer disperse auxiliary, and reductive cleaning auxiliary on the content of surface impurities of cheese dyed polyester yarns. The results indicated that most of the surface impurities of cheese dyed polyester yarns are polyester oligomers, accounting for up to 73% of the total impurities. The surface impurities of cheese dyed polyester increase with the increasing of dosage of dyestuffs, dyeing temperature and dyeing time. The additive of oligomer disperse auxiliary during dyeing process and the use of particular auxiliary during reductive cleaning can significantly reduce the surface impurities. |
