摘　　要：以分散紫900、分散红902、分散蓝825和分散橙BROD四只分散染料为例,比较其耐碱性和耐氧化性,考察以NaOH为介质的一浴一步法和一浴二步法碱性退浆染色短流程工艺。结果表明,该四只染料具有很好的耐碱性和耐氧化剂性,适合以2 g/L NaOH为介质的碱性条件染色,且其一浴一步法和一浴二步法碱性退浆染色短流程工艺的效果差别不大,能获得更好的弹性、柔软性和光滑性;采用该短流程碱性工艺加工时,控制不当纤维因过度失重导致断裂强度下降,应合理控制染色时间。Taking Disperse Violet 900,Red 902,Blue 825 and Orange BROD as examples,the resistance to alkali and oxidation of disperse dyes are compared,and one-bath-one-step and one-bath-two-step alkaline desizing and dyeing processes in NaOH solution are discussed.The results show that the four disperse dyes have good resistance to alkali and oxidation,and are suitable for alkaline dyeing in NaOH solution.The dyeing results of one-bath-one-step process is the same as those of one-bath-two-step process,and the fabrics have good elasticity,softness and smoothness.Because of strength loss in alkaline process,dyeing time should be carefully controlled.
