Abstract

Aiming at the technical drawback that traditional spinning technology cannot accurately control the color distribution of yarn and spin gradient color yarn, a three-channel numerical control spinning mechanism that regulates yarn color gradient online is put forward, and gradient color yarn is successfully produced. The coupling-combination color mixing mode of ternary color fibers is innovatively designed, and the mixing ratio matrix, mixing chromatography matrix and mixing chromatography, including all mixing samples, are constructed. Three kinds of gradient paths, namely the row gradient, column gradient and diagonal gradient, are planned based on the mixing ratio matrix, and the corresponding gradient chromatography matrix and gradient chromatography are given. Taking green, magenta and yellow rovings as an example, a three-channel numerical control spinning process was designed and three types of 16 kinds of gradient color yarns were spun. The results show that the knitted fabric of the gradient yarn spun by digitally adjusting the yarn blending ratio shows a periodic natural and soft gradient color. The mechanical properties and appearance quality of the gradient color yarn are close to the corresponding indexes of color-spun yarn, but there is still room for improvement.
