摘　　要：天然彩色棉色稳定性较差,在不同处理条件下会发生不同程度的色变.评价色变可运用测配色系统,但由于天然彩色棉的颜色特点,其评价标准不同于通常标准.研究表明:当色光不变时,ΔE<3表示基本无色差;当色光变化时,须根据ΔL,Δa和Δb,综合分析颜色的变化.The color of naturally colored cotton would change when treated in different conditions because of its instability of color. The color measuring and matching system can be used to evalu- ate color difference. But the standard of evaluation is different from the general standard because of the characteristic of naturally colored cotton. The results indicate that the color difference will be few when the hue doesn' t change and △< 3, but it will be necessary to use the △L, △a, △b to analyze synthetically color transformation when the hue changes.
