摘　　要：为降低涤纶织物染色温度,采用分散染料环保型载体染色法。通过分析环保型载体丁二酸二丁酯对涤纶纤维热稳定性以及玻璃化转变温度的影响试验,研究温度、时间以及载体用量对上染率的影响。结果表明,该载体对涤纶纤维具有增塑作用,对其热稳定性没有影响,可降低涤纶染色温度,提高分散染料溶解度和上染率。其优化的染色工艺为,载体4%(omf),染色温度105℃,保温时间45 min。载体染色织物颜色特征值和色牢度均与高温高压染色织物接近。In order to lower the dyeing temperature of disperse dyeing of polyester, eco-friendly carrier dyeing is carried out. The effects of carrier dibutyl succinate on the thermal stability and glass transition temperature of polyester fiber are analyzed, and the effects of temperature, time and dosage of carrier on dye-uptake are investigated. The results show that the carrier has plasticization effect to polyester fibers and has no effect on its thermal stability. It can lower the dyeing temperature effec- tively, increase the solubility of disperse dyes, and improve dye-uptake of disperse dyes obviously. The optimal carrier dyeing conditions are carrier 4% （omf）, dyeing at 105℃; for 45 min. The shade and color fastness of the carrier dyeings are as good as dyeings with high temperature and pressure process.
