Algorithm for color prediction of knitted fabrics during batch dyeing

Since it is difficult to directly measure the color of knitted fabric during batch dyeing,this paper proposed a new color prediction method by measuring the dye-uptake rate from the dye bath.Based on dyeing principle and computer color measuring and color matching,this method used mechanism modeling in combination with experimental modeling and developed a math model of fiber′ s surface reflectance during dyeing,dye uptake rate and initial concentration of the dye.An algorithm for color prediction of knitted fabric during batch dyeing was thus worked out combining the tri-stimulus value formula.This algorithm for color prediction was verified by dyeing pure cotton fabrics with three reactive dyes as examples.
