Method of computer union color measuring and matching for PA/cotton fabric

Considering the staining concept,the union color formula of PA/cotton fabric was established based on the theory of computer color measuring and matching.The influence degree of acid dye staining on cotton and reactive dye on PA was studied,and the results showed that the influence of acid dye staining on cotton could be neglected,but the influence of reactive dye on PA was noticeable.The union color formula was simplified according to this result.The union color matching method of PA/cotton fabric was established and the accuracy of this method was tested.The result showed the union dyed PA/cotton fabrics were accomplished using this method.The staining concept was implanted in the theory of color measuring and matching,and the program of union color matching for PA/cotton fabric was adjusted,and hence the error of union color matching was minimized.
