改性腈纶苏木直接染色工艺研究

摘要

The modified acrylic fiber was directly dyed with the sappanwood extract as natural dyes. The effect of the amount of sappanwood, dyeing temperature, dyeing time and washing times on K/S value and the characteristic value L*, a*, b*, C*, h° of the modified acrylic fiber was investigated. And the optimal pro-cess for modified acrylic fiber direct dyeing with sappanwood was determined. The results showed that the optimal dyeing process was sappanwood 60 mL/L, dyeing at 80 ℃ for 60 min, the higher K/S value and good washing fastness were obtained.%将苏木提取液作为天然染料对改性腈纶纤维直接染色,通过探究苏木提取液用量、染色温度、染色时间及洗涤次数对改性腈纶苏木直接染色K/S值和染色特征值L*、a*、b*、C*、h°的影响,确定改性腈纶苏木直接染色的最佳工艺条件.实验结果表明:当苏木提取液60 mL/L,80℃保温染色60 min时,可获得较高的K/S值和较好的耐洗色牢度.
