摘　　要：为实现快速、高效的染色效果,合成了具有不饱和双键的疏水性黄色蒽醌染料,通过泡沫施加方式经紫外光引发从而将染料接枝到棉织物上。采用傅里叶变换红外光谱对染料的化学结构进行表征,通过扫描电镜对染色前后棉织物的表面形貌进行表征。探讨了染料的质量分数、浴比、表面活性剂十二烷基硫酸钠浓度、光引发剂的质量分数及紫外光光照时间等因素对泡沫性能及染色性能的影响。结果表明,当染料的质量分数为织物质量的30%、浴比为1∶3、十二烷基硫酸钠质量浓度为2 g/L、光引发剂的质量分数为染料的5%、光照时间为6 min时,可获得良好的染色性能。To achieve fast and efficient dyeing effects,a hydrophobic yellow anthraquinone dye with an unsaturated double bond was synthesized.The dye was photografted onto cotton fabric after foam coating.The chemical structure of dye was characterized by FT-IR.The surface morphology of the cotton fabric before and after dyeing was characterized by SEM.The effects of mass fraction of dye,bath ratio,surfactant concentration of sodium dodecyl sulfate,mass fraction of photoinitiator and time of UV irradiation time on foam properties and dyeing properties were investigated.The results showed that when the mass fraction of the dye was 30%of the mass of the fabric,the bath ratio was 1∶3,the concentration of sodium lauryl sulfate is 2 g/L,the mass fraction of the photoinitiator was 5%of the dye and UV irradiation time was 6 min cotton fabric achieved better dyeing effect.
