摘　　要：研究了染色与水洗技术对聚对苯二甲酸丙二醇酯纤维条低聚物残留量的影响。根据精梳毛纺针织纱生产实际,在分析聚对苯二甲酸丙二醇酯纤维中低聚物的残留对混条复精梳等纺纱工艺影响的基础上,针对聚对苯二甲酸丙二醇酯纤维及低聚物的特点,综合分析酸性及碱性染色的差异,解决了染料选择的关键问题。采用新型碱性染色工艺及水洗的方法,控制了低聚物的沉积。实验结果表明,新型碱性染色工艺技术能有效消除低聚物,提高聚对苯二甲酸丙二醇酯纤维条的染色质量,实现了新型纱线的正常生产。This study is designed to the effect of the dyeing and washing on the oligomers residues of PTT fiber. According to the actual production of worsted knitting yarn,in the analysis of the oligomers residues of PTT fiber on the effect of blending,recombing and spinning technolgy,to the characteristics of PTT and oligomers,comprehensive analysis of differences between acidic and alkaline dyeing,and solved the key problems of dyes selection. The experimental results show that,the new dyeing technology can effectively eli minate oligomer,improve the dyeing quality of PTT fiber strips,realize the normal production of new yarn.
