Application of computer color matching of polyester/cotton blended fabric

In polyester/cotton(T/C) blended fabric dyeing,color staining often occurs to another kind of fiber,which results in lowering of the veracity of color matching.To solve this problem,color matching experiments for two-bath dyeing of T/C fabric with disperse/reactive dyes were carried out based on monochromatic color databases for pure cotton or for pure polyester in consideration of cotton staining.The experiment results show that this method can obtain higher color match veracity when applied to the single or two shade pitching of the samples with the projected amount in the recipe close to the actual dosage and less aberration after shading.However,the color matching veracity is lowered a little bit when this method is applied three shade pitching of samples.The factors affecting the color matching veracity were also analyzed.This color matching method is suitable for computer color matching of polyester/cotton blended fabric.
