【摘要】 研究了茜草与黄柏两种天然染料,在常规染色和铜媒染色中对棉织物的拼色性能,以改变天然染料色谱不全的缺点。结果表明,两种天然染料的上升速率与提升力的变化曲线较为相似,配伍性良好,可拼色染色。在拼色染色中,随着染料比例的不同,常规染色与媒染染色后织物的表观色深及颜色特征值会有差异,且媒染染色的色牢度较好(3～4级)。更多还原

【Abstract】 In order to overcom e the incom plete chrom atogram of natural dyes, the com bination dyeing of cotton fabric with madder and golden cypress in conventional dyeing and copper mordant dyeing is studied. The results show that the curves of dyeing rate and lifting power of the two natural dyes are similar.They have good compatibility and can be used for color matching. In color matching dyeing, with the different proportion of dyes, the apparent color depth and color characteristic values of fabrics will be different, and the color fastness of mordant dyeing is better up to Grade 3～4.更多还原
