摘　　要：传统的拔扎染虽图案造型独具特色,但色彩单调。活性染料地色具有可拔性,且颜色变化与其分子结构、活性基团、拔染的工艺条件有极大的关系。文章采用实验对比法,通过四种拔染剂对不同分子结构的活性染料的拔扎染效果研究分析,确定了保险粉法最适合活性染料多色拔扎染;对比保险粉法拔扎染不同工艺条件下的实验效果,确定其多色拔扎染的工艺条件是保险粉1~10 g/L,氢氧化钠1~10 g/L,温度60~80℃,时间1~10 min,浴比1︰30。实验结果表明,保险粉法对常用的活性染料都有拔染作用,且色彩变化多样;保险粉的浓度和温度对拔扎染的色彩图案效果影响较大;适当地降低拔扎染的工艺条件可以得到斑斓的图案。The pattern of traditional discharge and tie-dyeing is unique,but the color is monotonous.The reactive dyes is dischargeable,the change of color is related to its molecular structure,active group and dyeing process.In this paper,experimental comparison method was used.By comparing the discharge and tie-dyeing effect of four discharging agents for reactive dyes with different molecular structures,the result showed that the sodium hydrosulfite method is the most suitable for multicolor discharge and tie-dyeing of reactive dyes.By comparing the experimental effect of sodium hydrosulfite method under different process conditions,the optimum process conditions were confirmed as follows:sodium hydrosulfite 1~10 g/L,NaOH 1~10 g/L,temperature 60~80℃,time 1~10 min,bath ratio 1︰ 30.The experimental results showed that the sodium hydrosulfite can discharge all the commonly reactive dyes and change various colors.The temperature and the concentration of sodium hydrosulfite have the larger effect on color and pattern of color and pattern.The special multicolor effect can be obtained by reasonable selection of the process conditions.
