醋酯纤维/天丝混纺织物的低温染色

Low temperature dyeing of acetate/Tencel blended fabrics

采用一浴两步法对醋纤/天丝混纺织物进行低温染色,研究不同染色条件下分散染料染色织物的K/S值与色牢度。试验结果表明:在分散染料2%(omf),染色温度80℃时,醋纤/天丝混纺织物的染色性能最佳;与120℃高温染色的混纺织物对比,80℃染色织物的颜色深度无明显差异,织物经纬向拉伸断裂强力损失小,染色牢度略有提升。

The low temperature dyeing of acetate/Tencel blended fabric is carried out by one bath and two steps method.The K/S value and color fastness of the fabric with disperse dyes under different dyeing condi⁃tions are studied.The results show that when the disperse dye is 2%(omf)and the dyeing temperature is 80℃,the dyeing performance of the acetate fiber/Tencel blended fabric is the best.Compared with the blend⁃ed fabrics dyed at 120℃,the color depth of the fabrics dyed at 80℃has no significant difference.The fabric in⁃dicates little loss of tensile strength in the warp and weft directions,and the fastness of the dyeing is slightly improved.
