摘　　要：为实现预定色彩纺纱,将数控纺纱调控彩色纤维混纺比机制与六基色纤维全色相网格化混色模型相结合,构建了“多通道数控牵伸比、多元基色纤维混色比、纱线色彩”的三要素协同调控机制;基于红、黄、绿、蓝、青、品红等六基色纤维构建了色相调控范围为0~360°的包含60个网格点的全色相混色模型;基于网格点序号设计纺纱工艺参数并纺制了60种不同混色比的色纺纱,用其织成色织物;测试分析色纺纱条干均匀度、毛羽、断裂强力等外观质量与力学性能指标。结果表明:所纺60种纱线色彩变化趋势与六基色纤维全色相网格化混色模型色彩分布规律具有一致性;所纺纱线各项指标达到GB/T 398—2018《棉本色纱线》二级水平。Objective In conventional spinning process,colored yarns are prepared by blending different colored fibers through the process of fiber blending,grabbing,and drawing,but the process does not support online regulation,real-time control,and accurate digital adjustment of the yarn color.Inspired by color inkjet printing,the purpose of the paper is to investigate how to build a multi-channel computer numerical control(CNC)spinning system for making colored yarns of a full color phase.To this end,using the Newton′s three primary-color principle and through digital blending of the six primary colored fibers of red(R),yellow(Y),green(G),cyan(C),blue(B),and magenta(M),the color hue of the forming yarn can be changed from 0 to 360°,enabling the spinning of colored yarns of full color phase.Method The mechanism of controlling the mixing ratios of colored fibers by CNC spinning was combined with the full color phase mixing model of with six primary colored fibers,and the"multi-channel drafting ratios-colored fiber mixing ratios-colors of yarns"synergistic regulation mechanism was established.Based on the six primary colored fibers of red,yellow,green,blue,cyan and magenta,a full color phase mixing model with 60 grid points and a hue control of 0-360°was built.The spinning process parameters were designed based on the grid point number and a total of 60 different colored yarns and their fabrics in six color systems,consisting of R-Y,Y-G,G-C,C-B,B-M,and M-R,were fabricated.Results According to the fiber mixing ratio in the above model,60 colored fabrics were obtained(Fig.6).The color variation regularity was consistent with the regularity of mixing ratios of the six primary colored fibers,and also has consistency with the color distribution regularity of the full color phase grid mixing model.The colored yarns were measured and analyzed for appearance and mechanical properties such as yarn unevenness,surface hairiness and tensile strength.In terms of evenness,the coefficient of variation(CV)varied with the mixing ratios,w
