基于直接染料混配色织物的呈色规律研究

Color Regularity of Textile Based on Direct Dye Mixture

以纤维素直接染料直接红4BS、直接黄11、直接黄12、直接蓝2B为例,选择四种染料中任意两种染料以不同的质量比例均匀混配得到色彩均匀的彩色织物.在相同光照条件下观察染色后织物颜色,对比棉织物的表观色深和色卡颜色数值,得出直接染料混配色织物的呈色规律,即当一种直接染料质量固定不变,另一种直接染料质量相同梯度变化,将两种直接染料混合均匀,在浴比为1:80的条件下进行染色,直接染料混配色织物的呈色效果是非线性变化的.同时,分析影响配色的各个因素,包含染料的选择、染色工艺的控制、测色条件影响以及实验中称量的影响.

Taking cellulose direct dyes direct red 4 BS,direct yellow 12,direct yellow 11 and direct blue 2 B as examples,two of the four dyes are selected to mix and match with different mass ratios to get the color fabric with uniform color. We observe the fabric color under the same light condition,compare the color card color value,get the color rule of dye mixed color fabric,and analyze the factors affecting the color matching,including the choice of dye,dyeing process control,the influence of color measurement conditions and the influence of weighing in production. Controlling these factors can greatly improve the accuracy of color-matching fabric.
