The invention provides a
processing method and device for wrapping composite mixed-segment-
colored filament yarn and the
filament yarn. By using
filament yarn in different colors as the
raw material and adopting a hollow
ingot wrapping
compositing technology, the composite
yarn with the segment color characteristic of irregular 'pure color and mixed color' and 'mixed color and mixed color' is obtained. By means of the technology, the varieties and designs of the filament
yarn and fabric made from the same can be increased, and the design range of the filament
yarn fabric can be expanded. The structure and performance of the
resultant yarn are different from those of segment-
colored yarn produced through a short
fiber color
spinning method, the segment color control technology is simple, adjustment of the varieties and designs is convenient and flexible, and diverse combination
modes are achieved; when the obtained yarn serves as warp for weaving,
sizing is not needed, fabric
dyeing isnot needed, and only finishing is needed. Compared with mixed-
colored yarn processed through cabling, wrapping
compositing and other technologies, the filament yarn has the most remarkable
advantage that a segment
color effect of irregular distribution is achieved. The fabric is more vivid and lively in style. The technology adapts to a wide range of raw materials and can be used for combining allkinds of filament yarn to develop the composite filament yarn meeting different quality, performance and function requirements for production of knitted fabric and
woven fabric.
