摘　　要：以硫酸铁、明矾为媒染剂,采用茜素对绢丝灯芯绒进行后媒法染色,探讨染液pH值、媒染剂用量和媒染时间等因素对染色效果的影响,得到的优化染色工艺为:硫酸铁媒染剂用量10.0 g/L,pH值6~7,媒染时间20~25 m in;或明矾用量10.0 g/L,pH值2~3,媒染时间15 m in左右,染色织物的各项色牢度良好。Post-mordant dyeing of silk corduroy is carried out with ferric sulfate and alum as mordant respectively.Effects of pH value of dyeing bath,mordant dosage and dyeing time are discussed,and the optimum dyeing process is determined as follows: mordant dyeing for 20~30 min with ferric sulfate 10.0 g/L and pH value 6~7 or mordant dyeing for 15 min with alum 10.0 g/L and pH value 2~3.The mordant dyeings have good color fastness.
