摘　　要：研究了从鹿碲草中提取天然染料,并将提取液用于羊毛织物的染色工艺。结果表明,当NaOH浓度0.25 mol/L、提取温度100℃、提取时间70 min、鹿碲草与NaOH溶液质量比为1∶40时,鹿碲草的提取效果最好;当染色pH值3.0左右,染色温度100℃,染色时间60 min时,鹿碲草提取液对羊毛织物的染色效果最好。鹿碲草提取液对羊毛织物直接染色,得到的颜色为棕色,且耐摩擦色牢度及耐晒色牢度较好,但耐皂洗色牢度较差;用硫酸亚铁及硫酸铜媒染,可得到不同颜色的染色羊毛织物,媒染对染色羊毛织物的耐皂洗色牢度有一定的提高作用。The extraction of natural dye from wintergreens and it＇s dyeing on wool fabrics with the resulting extract were studied. It was found that the optimum extraction conditions were NaOH 0. 25 mol/L,extraction at 100 ℃ for 70 min,wintergreens and sodium hydroxide solution ratio of 1： 40 and the optimum conditions for the dyeing on wool fabrics with extract of wintergreens were pH value 3. 0, dyeing at 100 ℃ for 60 min. The brown and good color fastness to rubbing and light fastness of direct dyed wool fabric with extract of wintergreens were obtained, but color fastness to washing was poor. The different colors of dyed wool fabric could be obtained and color fastness to washing of dyed wool fabric could be improved by mordant dyeing whit ferrous sulfate and copper sulphate.
