摘　　要：采用分散染料/中性固色活性染料在近中性条件下对涤棉混纺针织物染色,探讨了染料、苯甲醇和Na Cl用量,以及染色温度和时间对涤棉织物染色K/S值的影响,测试了染色织物的牢度。研究结果表明,涤棉织物一浴低温染色的最佳工艺条件为:分散染料1%(omf),中性固色活性染料3%(omf),苯甲醇30 m L/L,Na Cl 30 g/L,在100℃下保温染色60 min。染色织物的耐皂洗色牢度和耐摩擦色牢度可以达到4级以上,均能够达到服用性能要求。Disperse dyes and neutral fixing reactive dyes were applied to dyeing of polyester/cotton blend knitted fabrics. The effects of dosage of dyes, benzyl alcohol and sodium chloride, dyeing temperature and time on K/S value of dyed polyester/cotton fabrics were discussed. The fastness of the dyed fabric was also tested. The results showed that the optimal one bath low temperature dyeing process for polyester/cotton blend fabric was disperse dyes 1%（omf）, neutral fixing reactive dyes 3%（omf）, benzyl alcohol 30 mL/L, sodium chloride 30 g/L, dyeing at 100 ℃ for 60 min. The washing fastness and rubbing fastness of dyed fabrics were both more than grade 4, which could meet the clothing requirements.
