摘要
采用煎煮法,以水为溶剂,从苏木中提取天然染料,通过正交试验探讨了真丝织物苏木染料染红色系的工艺,并对染色真丝织物的各项牢度进行评价。优化的染色工艺为:预媒染剂明矾6%(omf),预媒染温度85℃,预媒染时间40 min;染料5%(omf),染色浴比1:30,70℃染色50 min,使用原始染液pH值。苏木染色真丝织物具有较好的耐日晒牢度和耐摩擦牢度。
Natural dyes are extracted from Caesalpinia sappan with water as a solvent by decoction method. Dyeing process of silk fabric in red with Caesalpinia sappan dye is carried out through orthogenal experiments and the fastnesses of the dyed silk fabric are tested. The optimized process is： the pre-mordant alum 6%（omf）, pre-mordant dyeing at 85 ℃ for 40 min, dyes 5%（omf）, dyeing bath ratio 1：30, dyeing at 70 ℃ for 50 min. The dyed silk fabric shows satisfactory color fastnesses to sunlight and rubbing.
