The present invention relates to full-color-
gamut color mixing model construction based on a cylindrical
color model, and a color regulation and control method for a formed
yarn using same. Firstly, on the basis of multivariate
primary color fibers obtained by means of a cylindrical
color model, a cylindrical full-color-
gamut color matching model corresponding to the multivariate
primary color fibers is constructed; then, a multivariate
primary color fiber grid
color mixing model is obtained by constructing a ternary
nonlinear coupling-superposition
color mixing model; next, a full-color-
gamut grid color mixing model is obtained by means of the integration of node coordinates and grid point coordinates; and finally, on the basis of the structure of a three-channel
numerical control rotor
spinning system, a
numerical control rotor
spinning formation process related to ternary
nonlinear coupling-superposition color mixing samples and a three-element coordinated regulation and control mechanism for a formed
yarn color, a color
mixing ratio and a cotton feeding roller speed ratio are constructed, and according to the full-color-gamut grid color mixing model, a
spinning process of the three-channel
numerical control rotor spinning
system with respect to a melange
yarn is constructed, such that the color regulation and control of a formed yarn can be efficiently implemented, thereby improving the actual efficiency of color regulation and control.
