摘　　要：研究硫酸钠用量、pH、温度、时间等对儿茶色素上染真丝织物的影响,分析媒染剂硫酸铝对儿茶色素染色真丝的影响。结果表明,染色优化工艺:pH 4,90℃,70 min,加入适量硫酸钠可提高匀染性;随着儿茶色素用量增加,染色织物K/S值增大,但总体得色量不高;媒染对染色织物的颜色特征值和色牢度影响不大。The effects of sodium sulfate dosage,pH,temperature and time on catechu pigment dyeing of silk fabric were studied,and the effects of mordants aluminum sulfate on catechu pigment dyeing of silk fab⁃ric were analyzed.The results showed that the optimum dyeing process were as follows:pH 4,90℃,70 min,and sodium sulfate was added to improve the levelness.With the increase of catechu pigment content,the K/S value of fabrics increased,but the overall color yield was not high.Mordant dyeing had little effect on the col⁃or characteristic value and color fastness of dyed fabrics.
