摘要/Abstract

摘要： 通过测试聚酯/聚酰胺织物（以下简称改性聚酯）的沸水收缩率，改性聚酯/棉(65/35)混纺织物的最佳前处理条件，改性聚酯织物常压染色和改性聚酯/棉织物分散/活性染料一浴一步法染色的K/S、色牢度，对新型改性聚酯及其棉混纺织物的染色性能进行了研究。实验结果表明：染前热定型后，改性聚酯及其棉混纺织物的经向、纬向收缩率都低于5%；改性聚酯/棉织物的前处理优化工艺条件为：双氧水4g/L、精炼剂3g/L 、NaOH4g/L；改性聚酯织物可以常压染色；改性聚酯/棉分散/活性染料一浴一步碱性染色匀染性良好，染色样品的熨烫、日晒、干摩擦牢度都达到4级及以上。

Abstract: Dyeing properties of polyester/polyamide fiber (referred to as modified polyester) and it’s cotton blended fabric were researched based on determination of boiling water shrinkage rate of modified polyester fabric, the best pretreatment conditions of modified polyester/cotton(65/35), and K/S and color fastness of modified polyester fabrics dyed under normal pressure and modified polyester/cotton dyed with disperse/reactive dyes one-bath one-step method. The experimental results have shown that warp and weft shrinkage rates of modified polyester and it’s cotton blended fabric were lower than 5% after heat setting. Optimization conditions of pretreatment process of modified polyester/cotton fabric was H2O2 of 4 g/L, scouring agent of 3g/L and NaOH of 4g/L. Modified polyester fabric could be dyed under normal pressure. Levelness performance of disperse/reactive dyes one-bath one-step dyeing was satisfactory. Fastnesses to ironing, sunlight and dry rubbing of dyed samples were reached 4 grade and above.

Key words: polyester/polyamide, blended fabric, dyeing under normal pressure, one-bath one-step process, color fastness
