The invention relates to the technical field of
spinning with regenerated cotton, in particular to a technique of blending
colored regenerated flake yarns, which sequentially includes steps: firstly, preparing cotton; secondly, performing blowing; thirdly,
carding the cotton, namely making recycled
polyester into neps on a cotton card, collecting the cotton neps,
dyeing the cotton neps into
colored neps, placing a hopper above a web of the cotton card, and using the hopper to scatter the
colored neps onto the web to make colored regenerated blended flake slivers; fourthly, performing drawing; fifthly, performing roving; and sixthly performing
spinning. Compared with the prior art, the technique has the advantages that the regenerated cotton, the fine staple cotton and the recycled
polyester are blended, the recycled
polyester is made into the neps in the cotton
carding phase, the neps are dyed and scattered onto the web through the hopper so as to generate colored flakes, and accordingly, the colored regenerated blended flake yarns have the good environment protection function, forming strength of the colored regenerated blended flake yarns is improved, the cotton neps are reduced, and
moisture conductivity, breathability and attractiveness of the colored regenerated blended flake yarns are all improved.
