摘　　要： 采用提取的天然茶叶染料对真丝绸织物的染色性能进行研究,通过正交试验及单因素分析,探讨了染色温度、pH值、保温时间及不同媒染剂的影响,得出茶叶染真丝织物最佳工艺条件,并对染色的各项牢度指标作了比较。结果表明,在浴比1∶20、沸煮、弱酸(pH=4～5)条件下,采用铜离子后媒法染色60min得到的真丝织物具有良好的得色量和染色牢度。 The dyeing properties of the natural tea dyes on silk fabrics were studied.Through orthogonal test and single factor analysis,the influences of the dyeing temperature,pH value,temperature-holding time and dye mordant were discussed to obtain the optimal conditions of natural tea dyes on silk fabrics.The indexes of color fastness were also compared.The results showed that the silk fabric had good color yield and color fastness if dyed by post-mordant methods with copper ion for 60 minutes on the condition of liquor ratio 1∶20,boiling and weak acid（pH=4~5）.
