Problems solved by technology

[0003] CN107177917A discloses a method for producing worsted cotton flax high-count yarn with cotton spinning equipment, using pure cotton and flax blended high-count yarn, and cellulose fiber and cotton fiber are very different in terms of mixing and preparation processes, and the produced high-count yarn Yarns have certain differences in performance, which are reflected in the large length differences of cellulose fibers, low spinnability, and low tension. Therefore, how to reduce the difficulty of different fibers in the blending process through a certain pretreatment process has always been a problem. research hotspots

Abstract

The invention belongs to the technical field of spinning methods, in particular to a preparation method of a pure spinning regenerated cellulose fiber card sliver. The preparation method comprises thefollowing steps: regenerated cellulose fiber pretreatment; A002D bale plucker; A036B cotton slitter; A092A cotton feeding machine; A076C lapper; A186G carding machine; pure spinning regenerated cellulose fiber card sliver. The level of difficulty of manufacturing different fibers in the blending technology is lowered, and the industrial application range of regenerated cellulose fiber is improved.

Description

technical field [0001] The invention belongs to the technical field of spinning methods, in particular to a method for preparing raw slivers of pure spinning regenerated cellulose fibers. Background technique [0002] Regenerated fiber and flax fiber, bamboo fiber, sisal fiber and other fibers can be made into limit materials with different styles through blending process, which can be used in many fields, such as high-end clothing and home textile fabrics. The products also have the characteristics of regenerated cellulose fiber. Skin-friendly, smooth, soft and other wearing properties, as well as the rough style, health care function, cool and comfortable feeling of flax fiber, bamboo fiber, sisal fiber and other fibers. [0003] CN107177917A discloses a method for producing worsted cotton flax high-count yarn with cotton spinning equipment, using pure cotton and flax blended high-count yarn, and cellulose fiber and cotton fiber are very different in terms of mixing and pr...
