摘　　要：针对传统活性染料水浴染色上染率低、废水排放量大及电解质含量高等问题,研究了活性染料Pickering乳液非均相浸渍染色工艺。以有机醇醚作为染色介质,疏水性纳米Si O2粒子作为乳化剂,将安诺素藏青L-3G染料水溶液分散于有机醇醚中,并对棉机织物进行染色,测试着色织物的K/S值、固色率及匀染性。结果表明,活性染料Pickering乳液染色最佳工艺为:水质量分数15%,染色时间30 min,温度70℃,Na2SO4质量分数0.6%,碱剂质量浓度20 g/L,纳米Si O2粒子质量分数1.5%;活性染料安诺素藏青L-3G在Pickering乳液中的固色率可达到85%,K/S值及固色率均较传统水浴染色更高,同时皂洗牢度和耐摩擦牢度均达4~5级,匀染性较好。In order to effectively solve the problems of low dye uptake,a large amount of waste water discharge and high electrolytes content in waste water caused by the conventional reactive dyeing in water bath,the heterogeneous exhausting dyeing of reactive dye on cotton fabrics in Pickering emulsion was investigated. Organic alcohol ether and hydrophobic Si O2 nanoparticles were used as the dyeing media and emulsifier,respectively. ANOZOL Navy L-3 G dye was dispersed into organic alcohol ether and dyed cotton fabrics. Finally,K/S value,fixation and levelness of dyed fabrics were measured. The results show that the optimum process conditions are water content of 15%,time of 30 min,temperature of70 ℃,Na SO4 of 0. 6%,Na2 CO3 of 20 g/L and nano-Si O2 particles concentration of 1. 5%. The fixation of ANOZOL Navy L-3 G reactive dye in Pickering emulsion reaches 85%, which is superior to conventional dyeing. The washing and rubbing fastness of dyed fabric are 4-5 and levelness of dyed fabrics is satisfactory.
