摘　　要：优化了樟树叶天然染料微波提取的条件及提取液对羊毛染色的条件。讨论了氢氧化钠用量、微波功率、辐射时间等对提取效果的影响,讨论了提取液对羊毛染色时染色pH值、染色温度、时间、硫酸钠用量等对染色效果的影响。结果表明,微波提取的优化工艺为:氢氧化钠0.25 mol/L、微波功率595 W、辐射时间11 min、料液比1∶20。提取液对羊毛直接染色的优化工艺为:染液pH值5.00左右,染色温度100℃,时间60 min,浴比1∶50。樟树叶提取液染色羊毛具有一定的牢度,媒染可适当提高染色牢度。Microwave extraction conditions for natural dye from camphor leaves and the dyeing conditions on wool fabrics with resulting extract were optimized. Factors exerting influence on extraction results such as NaOH concentration, microwave power, extraction time, and factors exerting influence ondyeing results on wool fabrics such as dyeing pH value, dyeing temperature, dyeing time, Na2SO4 concentration were discussed. It was found that the optimum conditions for the extraction were as follows： NaOH 0.25 mol/L, microwave power 595 W, extraction time 11 min, solid to liquid 1 ： 20. The optimumconditions for the dyeing on wool fabrics were as follows： pH value 5.00, dyeing temperature 100 ℃, dyeing time 60rain, bath ratio 1 ： 50. The dyed wool fabrics with resulting extract had definite fastness and the fastnesses properties could be improved by mordanting.
