Abstract: In order to find a good recipe to reproduce a target color for pre-dyed fibers,three primary samples,red,yellow and blue viscose,were used to prepare 36 fibre blends.A spectrophotometric color matching algorithm based on Stearns-Noechel model is used to predict recipes for 36 viscose blends.The results indicate that the maximum color difference is 1.03 CIELAB units,and the minimum,0.10 CIELAB units.This demonstrates that the algorithm is suitable for color matching of fiber blends.
