摘　　要：探究了中药女贞子染料对丝绸染色的可行性及条件。通过单因素试验与正交试验讨论了提取温度、提取时间、料液比等对染料提取效果的影响,以及染色p H、染色温度、染色时间、浴比等对真丝绸染色效果的影响。比较了预媒染、同浴媒染、后媒染3种染色方式,并测试了织物的耐皂洗色牢度及耐汗渍色牢度。结果表明,女贞子提取的优化工艺为:温度85℃,时间90 min,料液比1∶70;女贞子提取液直接染色真丝绸的优化工艺为:p H=5,温度40℃,时间40 min,浴比1∶60;另外,媒染可有效提高女贞子提取液染色真丝绸的上染率,中药女贞子染料染色真丝绸的色牢度达国家优级品标准。The feasibility and conditions of silk fabric dyeing with ligustrum lucidum ait dye were studied. The influences of extraction temperature, extraction time and solid to liquid ratio on extraction results, and ef- fects of dyeing pH, dyeing temperature, dyeing time and liquor ratio on dyeing results of silk fabric were discussed by single factor and orthogonal experiments. Three different dyeing methods, pre-mordant, meta-mordant and post-mordant dyeing were compared. And the color fastness to washing and perspiration of silk fabric were tested. The optimum conditions for the extraction were： extracting at 85 ℃ for 90 min, 1：70 of solid to liquid ratio. The optimum dyeing conditions were： pH=5, dyeing at 40 ℃ for 40 min, 1：60 of liquid ratio. Furthermore, mordant dyeing could effectively improve the uptake, and the color fastness of dyed silk fabric with ligustrum lucidum ait dye met the demand of national excellent grade goods.
