摘　　要：以聚乙二醇油酸酯为涤纶分散染色的匀染剂,探讨其在染色过程中对染料的分散性、缓染性和移染性,并结合作用模型探究对染料的作用机理。结果表明,在染色过程中,聚乙二醇油酸酯能够提升染料在水中的分散性,同时对染料具有较好的缓染性和移染性,并且对染料的移染作用主要发生在纤维的表面和表层结构。Polyethylene glycol oleate was used as the leveling agent in the process of dyeing on polyes⁃ter fibers,and its effect on the dispersion,mitigation and migration properties of disperse dyes during dyeing was discussed,and the mechanism of the leveling agent on disperse dyes was also explored.The results showed that polyethylene glycol oleate could improve the dispersion property in water during the dyeing pro⁃cess,and had good mitigation and migration properties on disperse dyes.The migration of dyes mainly oc⁃curred on the surface and outer structure of the fiber.
