摘　　要：针对脱色羊绒经酸性媒介染料染色后得色量低,湿牢度差的问题,采用2种阳离子改性剂Indosol E-50和Optifix EC对脱色羊绒进行改性预处理,并对改性后的脱色羊绒进行酸性媒介染料染色,筛选出适宜的阳离子改性剂Optifix EC,分析改性剂用量、pH值、时间及温度对脱色羊绒酸性媒介染料染色的K/S值及皂洗牢度的影响,确定最佳改性工艺。研究结果表明:在温度65℃,pH值为7的改性条件下,阳离子改性剂Optifix EC用量4%(owf),对脱色羊绒改性35 min后染色,其K/S值及皂洗牢度均有明显提升。In this paper,two kinds of cationic modifiers,Indosol E-50and Optifix EC,were used to modify the decolorization velvet degeneration.The Optifix EC is screened as the good modification effect agent.And the effects of modification agent dosage,modification time,temperature and pH value on K/S value and color fastness of acid mordant dyes dyed decolorization cashmere are analyzed.The optimum modification process is determined as following:modifying agent Optifix EC4%(owf),modification temperature65℃,pH value7and time35min.The K/S value and color fastness of dyed cashmere are significantly improved.
