采用酸性金属络合染料对锦氨织物进行染色,从染料、染色工艺、助剂三个角度探讨了对染色牢度的影响.结果表明:酸性金属络合染料对锦氨织物染浅、中及中深色的牢度较好;染深色时,需通过工艺调整及助剂辅助.其优化的工艺条件为:染色温度93℃,保温时间30 min,染浴pH值在3～4,配合1.0 g/L氨纶防沾色剂,2％(omf)酸性固色剂DM-2539G及2.0 g/L增进剂CIBAFIX ECO后处理,各项牢度指标能提升到3-4级及以上.“,”The nylon/polyurethane fabric was dyed with metal complex acid dyes.And the influence on color fastness was discussed from three aspects of dyes,dyeing process and auxiliaries.The results showed that the color fastnesses of metal complex acid dyes to nylon/polyurethane fabric were good in light,medium,medium dark colors.When dyeing dark color was 3％(omf),it was necessary to adjust through process and assistant.The optimized process conditions are:dyeing temperature 93 ℃,dyeing holding time 30 min,dyeing bath pH value at 3～4,and finishing with 1.0 g/L polyurethane anti-staining agent,2％(omf) acidic dye-fixing agent DM-2539G and 2 g/L promoter CIBAFIX ECO,and the fastness indicators can be raised to level 3-4.
