Application of Stearns-Noechel model on color blending of naturally colored cotton

In order to improve the design efficiency for blending fabric of natural colored cotton,Datacolor SF600 + was used to test the color date of mixed fiber,blended yarns and interwoven fabric.The color of loose material group,blended yarns and interwoven fabric was predicted by Stearns-Noechel model,and then CIEDE2000 color difference formula was prepared to calculate the color difference of the prediction and the practice. The model parameters for loose material group,blended yarns and interwoven fabric were optimized. The optimization values of M are 0. 096,0. 128 and 0. 01,and the corresponding color differences are 1. 72,3. 40 and 4. 90,thus is established the reflectance prediction model amung fiber,yarn and fabric under this experimental condition is established.
