摘要
采用乙醇浸提法从染料紫檀木粉中提取染料色素,并用于羊毛织物的染色。研究了染液中乙醇质量分数、染液pH、染色温度与时间,以及媒染剂等对羊毛织物染色效果的影响。优化的染色工艺为:染液中乙醇质量分数为20%、pH=4、染色温度80℃、染色时间40 min。采用同浴媒染法进行染色,氯化亚铁媒染后织物K/S值最大,耐日晒色牢度提高1~2级。
The pigment extracted from Pterocarpus tinctoricus powder by ethanol extraction method is used to wool fabric dyeing.The effects of ethanol concentration,p H,dyeing temperature and time,and mordant on the dyeing results of wool fabric are studied.The optimized metachrome dyeing process is ethanol 20%,pH=4,dyeing at 80℃for 40 min.TheK/S value of the fabric dyed with ferrous chloride mordant is the largest and the color fastness to sunlight is improved by Grade 1-2.
