Color matching in two color melange fiber blends by stearns - Noechel model

Melange color is a color effect obtained by mixing of fibers in different colors before the blend. One of the biggest problems encountered in the work of mélange colors in textile is that, not accurate estimation of fiber colors provides desired color. In this study estimating the mélange color pre-production, yellow, red and blue colors used in the viscose and polyester fibers. These fibers in different ratios and two colors mixed and 165 mélange-colored bands were obtained. Color values of these bands, measured in the spectrophotometer were expressed in CIELab 1976 (D65 illuminant and 10o standard observer) unit. Stearns - Noechel model has been the basis for color forecasting. To calculate the model M, in the coefficient, a new approach was developed. A different M coefficient was calculated for all wavelengths in each mix, 400-700 nm (10nm intervals) range. The color calculations are performed, using the M coefficients. The average color difference between the measured color values and calculated color values was found as 1.15 CIELab units. This result suggests that in the fiber blend estimating the colors of the Stearns - Noechel model might be a sufficient result
