摘　　要：采用自制的液体分散蓝291对薄型涤纶织物进行连续染色,考察了染色工艺条件和热水洗工序对织物K/S值、匀染性、耐摩擦色牢度和残液吸光度的影响。结果表明,当增稠剂PTF-A质量分数为0.18%,增稠剂PTF-S质量分数为0.12%,防泳移剂PD质量分数为0.5%,渗透剂JFC质量分数为0.3%,聚酯聚醚D_2质量分数为2%,180℃汽蒸4 min时,染色织物能获得较好的K/S值、匀染性和耐摩擦色牢度。液体分散蓝291的连续染色性能明显优于固体粉状分散蓝3GR,增稠剂相互复配和聚酯聚醚D_2能提高织物的得色深度。The continuous dyeing process of light-weight polyester fabric with self-made liquid Disperse Blue 291 is carried out.The effects of dyeing process and hot-water washing process on K/S value,levelness,color fastness of the fabric and absorbance of residual liquor are discussed.The results show that under the conditions of 0.18% thickener PTF-A,0.12% thickener PTF-S,0.5% anti-migrating agent PD,0.3% penetrant JFC,and 2% polyester polyether D2,steaming at 180℃ for 4 min,the fabric can obtain high K/S value,excellent levelness and color fastness.The continuous dyeing performance of liquid Disperse Blue 291 is significantly better than that of solid powder Disperse Blue 3GR.Thickeners compounding and polyester polyether D2 can improve the color depth of the fabric.
