Converting compacted fiber bales into loose pulp using the needles and tines of a loosening machine.
Receiving a large batch of well-mixed components, which makes it possible to produce yarn of a certain stable quality for a long time.
Further loosening of the pulp and removal of trash impurities. Carried out on scutching machines.
Removal of short fibers and obtaining a tape consisting of long, uniform along the length, well-straightened and parallel fibers. On combing machines, the fibers are combed with special combs on both sides.
Getting a semi-finished product more uniform in thickness. To do this, the tape is folded in several folds and pulled out. Processing can be carried out sequentially several times on several draw frames, as a result of which the thickness of the resulting product is leveled.
Folding and pulling tapes
Production steps include:
Separation of the scraps into separate fibers, straightening, parallelizing them, cleaning from the remaining impurities and defects. On carding machines, cotton is combed with needle-like surfaces. The material is passed between a rapidly rotating drum and slowly rotating needle belt plates or rollers. The combed fiber is removed from the surface of the removable drum over the entire width with a fast-speed comb and enters a round funnel, forming into a carded belt
Gradual pulling of the sliver into the roving, carried out on roving frames. It includes the final stretching to the desired thickness, twisting it and winding it onto the packages.
Obtaining yarn from roving, winding the yarn on a package, convenient for further processing. Carried out on spinning machines.
