Abstract:

Aiming at the technical drawback that traditional spinning technique cannot be accurately control the color distribution in yarns and hence is unable to spin gradient colored yarns, a three-channel numerical control spinning mechanism that regulates yarn color gradient online was put forward, and the gradient colored yarn was successfully produced. The coupling-combination color mixing mode of three colored fibers was designed, and the mixing ratio matrix, mixing chromatography matrix and mixing chromatography including all mixing samples were constructed. Three gradient paths, i.e. the row gradient, column gradient and diagonal gradient, were planned based on the mixing ratio matrix, and the corresponding gradient chromatography matrix and gradient chromatography were generated. Taking green, magenta and yellow colored rovings as an example, a three-channel numerical control spinning process was designed and three types of 16 gradient colored yarns were spun. The results show that the knitted fabric made from the gradient yarn spun by digitally adjusting the yarn blending ratio shows periodic natural and soft gradient colors. The mechanical properties and appearance of the gradient colored yarn are close to the corresponding indexes of color-spun yarn, but with rooms for improvement.

Key words: symmetrical periodic gradient color, gradient yarn, color mixing mode, gradient mode, gradient path, numerical control spinning
