The invention provides a dyeing quality improver for polyester-based fiber materials characterized by comprising a polyester copolymer, obtained by polycondensation of a dibasic acid component containing a dibasic acid with a sulfonate group in an amount of 15-65 mol% and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500, having a molecular weight of 3000-30,000 and containing polyoxyethylene chains in the molecule in an amount of 10-40 mass%, and at least one compound selected from among styrenated phenolalkylene oxide addition products and higher alcohol alkylene oxide addition products. It is possible to solve the problem of adhesion of polyester oligomers and the problems of dye contamination and foreign matter contamination, during dyeing of polyester-based fiber materials.
本发明提供了一种用于聚酯基纤维材料的染色质量改进剂,其特征在于包括一种聚酯共聚物,该聚酯共聚物由含有磺酸基的二元酸组分(含量为 15-65 mol%)和二元醇组分(分子量为 900-3500 的聚乙二醇)缩聚而成、分子量为 3000-30,000 且分子中含有聚氧乙烯链(含量为 10-40 质量%)的二元醇组分,以及至少一种选自苯乙烯化环氧苯丙烷加成产物和高级醇环氧烷加成产物的化合物。这样就可以解决聚酯低聚物的粘附问题以及聚酯基纤维材料染色过程中的染料污染和异物污染问题。
