Embodiment Construction

[0013] The present invention will now be further described.

[0014] In the present invention, the colored regenerated snowflake blended yarn is formed by blending recycled cotton, fine-staple cotton and recycled polyester, the length of the recycled cotton is 15 mm, and the fineness is 5,700, the length of the fine-staple cotton is 28 mm to 29 mm, and the fineness is 7000-7500 pieces, the length of recycled polyester is 38mm, and the fineness is 6000 pieces. Concrete process steps are as follows:

[0015] 1. Cotton blending: Pack recycled cotton, fine-staple cotton, and recycled polyester into sandwich bags.

[0016] 2. Cleaning: After humidifying the sandwich bag, the sandwich bag is sequentially blended on the A002 plucking machine, FA106 cotton opener, A035 mixed cotton opener and A076C lapping machine to form colored regenerated snowflake blended rolls. Among them, the speed of A002 catching machine was increased to 700 r / min; the speed of card beater in FA106 cotton op...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of regenerated cotton spinning, in particular to a colored regenerated snowflake blending process. Background technique [0002] With the improvement of people's living standards, the requirements for the fashion of clothing are getting higher and higher, especially the secondary utilization of textile raw materials is more and more interesting. Colored regenerated cotton blended yarn is a kind of international and domestic popular green, fashionable and environmentally friendly yarn. The yarn is spun by adding a special spinning process device in the carding process, and the production count is 16. S ~32 S . Because the appearance of the fabric produced with this yarn presents a snowflake-like effect of different colors, it is also called "color snowflake blended yarn". Colored snowflake blended yarn needs to be carded with colored knots and spun into ring-spun yarn in order to achieve the effect of colo...
