多通道转杯花色纱成纱规律

Study on Rule of Yarn Formation of Multi-Channeled Rotor Spun Multicolor Yarn

利用多通道转杯花色纱成纱工艺及特点纺制花色纱。通过改变色彩变化梯度及段长时间纺制不同工艺参数的渐变花色纱,研究变化梯度及变化时间对纱线颜色变化过渡段的影响,并分析过渡长度的变化规律。结果显示:在纱线线密度相同的情况下,花色纱的过渡长度随着颜色变化梯度的减小而增大,随着片段时间的减小而减小。

Based on technology and the characteristics of the multi-channeled rotor spinning,the multicolor yarns were prepared.By changing the gradient of color change and the period time of length,different gradient yarns of different process parameters were spun.The effects of changing gradients and changing time period on the color transitions of yarns were studied,and the variation of transition length was analyzed.The results show that under the same yarn linear density,the color transition length of the gradient yarn increases with the decrease of the gradient of color change,and decreases with the decrease of the fragment time.
