| Summary: | By applying the Ostwald color solid in spinning, we investigated how to correlate the Ostwald color solid with spinning process parameters and achieve the wide-color gamut-blended yarn spinning, based on rotor spinning principles. First, we developed a coupling model for mixing the six primary colors (red, yellow, green, blue, black, and white) at 0%–100% concentrations. This led to the creation of a wide-color gamut grid color mixing model and visual chromatography that aligns with the Ostwald color solid. Next, we utilized a three-channel numerical control rotor spinning platform to link the spinning process, primary-color fiber mixing concentrations, and the formation of yarn colors. The color value matrix, the primary-color fiber mixing ratio matrix, and the spinning process matrix corresponding to all grid points were further obtained. Using six primary-color rovings, we produced 120 blended yarns and their respective knitted fabrics evaluated the performance of blended yarns and the Lab color values of their knitted fabrics, and obtained the Ostwald color solid fabric chromatograms. Testing showed that the blended yarns’ strength, evenness, and hairiness met FZ/T 12,001—2015 standards. The fabric chromatograms exhibited uniform mixing, and smooth transitions, establishing a new theoretical and methodological approach for creating wide-color gamut-blended yarns. |
