Combed cotton and chemical fiber blending production process

Abstract

The invention discloses a combed cotton and chemical fiber blending production process. The specific steps are as follows: ginned cotton is taken out, put into a cotton cleaning and picking area and produced into needed slivers, and after the slivers are predrawn in the first step of drawing, predrawn slivers are obtained; the predrawn slivers are then produced into needed laps by a lap former; the laps are then produced into needed combed slivers by a combing machine and stored for later use; viscose is taken out and put into a cotton cleaning and picking tray, and needed viscose slivers are produced; the produced viscose slivers are taken out and drawn by a first-step drawing frame, so that needed slivers are produced; the obtained slivers and the combed slivers are produced into mixed first slivers; the obtained mixed first slivers are produced into needed mixed final drawn slivers; the obtained mixed final drawn slivers are produced into needed blended yarns. The combed cotton and chemical fiber blending production process is suitable for combed cotton and chemical fiber blending, can effectively improve the uniformity of blending, and reduces neps caused by fiber injuries; original six sections of drawing are changed into five sections, and while capability is the same, a series of problems related to occupied floor area, electricity saving and the like which are caused by equipment investment also can be reduced.

Description

technical field [0001] The invention relates to the field of chemical fiber manufacturing, in particular to a manufacturing process of combed cotton and chemical fiber blending. Background technique [0002] At present, the chemical staple fibers that can be individually slivered on the carding machine have obvious problems of uneven length and short segments due to the influence of their physical properties compared with cotton sliver; After the combing) process, the sliver is relatively mature, so that the fiber is damaged and the strength is reduced; the cohesion between the fibers is poor, and according to the current process, there are relatively many neps in the drawing warp of the 3-way blending, and the blending uniformity is not ideal . Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a simple process flow, low production cost, energy-saving and environment-friendly...
