Spinning process of chemical-fiber combed yarn

Abstract

The invention relates to a spinning process of chemical-fiber combed yarn, comprising an opening picking combination machine process, a cotton carding process, a drawing and roving process, a spinning process and a winding process. A pre-drawing process, a drawing and coiling process and a combing process are added between the cotton carding process and the drawing and roving process. The complete process comprises the following steps of: the opening picking combination machine process, the cotton carding process, the pre-drawing process, the drawing and coiling process, the combing process, the drawing and roving process, the spinning process and the winding process. The invention has the advantages that chemical-fiber yarn produced by utilizing the process flows under the spinning technological condition obviously reduces nubs and neps, improves yarn evenness and strength, thus customers give higher evaluation on yarn quality.

Description

technical field [0001] The invention relates to spinning technology, in particular to a chemical fiber combed yarn spinning process. Background technique [0002] At present, the existing chemical fiber yarns all adopt the traditional carded ring spinning process, that is, the process flow is blowing process, carding process, drawing process, roving process, spinning process, and winding process. Insufficient carding effect in the middle, resulting in insufficient fiber straightness and parallelism, and fiber chaos in the semi-finished product, which affects the mechanical and physical properties of the yarn to a certain extent, resulting in high slubs and many neps in the finished yarn. Users who use this series of yarns have always reported that the fabrics made have small thick places, white stars and poor fabric styles. Contents of the invention [0003] In order to improve the carding effect of chemical fiber, reduce yarn slubs and neps, and improve yarn and fabric q...
