Technology for heavy quantitatively producing high-grade weaved yarns by using card slivers by Zheng spinner blowing-carding combined carding machine

Abstract

The invention provides a technology for heavy quantitatively producing high-grade weaved yarns by using card slivers by a Zheng spinner blowing-carding combined carding machine and relates to the technical field of production technology of the high-grade weaved yarns. The production technology comprises the following steps in turn: preparing cotton; opening picking; carding cotton; combing; drawing; roving; spinning; post-processing; and checking end products, wherein the processes of preparing cotton and opening picking are finished by adopting Zheng spinner blowing-carding; the processes comprise the steps of grabbing cotton back and forth, removing impurities by a metal probe, automatically mixing cotton, opening picking in a double-shaft flowing form, opening original cotton, removing impurities and mixing; the process of carding cotton comprises the steps of mixing cotton, beating and opening cotton, feeding cotton in middle, scutching by using a sawtooth roller, coagulating cotton, conveying cotton, feeding cotton and carding cotton by using a carding machine; and the process of carding cotton is mainly used for finishing carding, removing impurities, uniformly mixing and twisting into strips. The Zheng spinner blowing-carding production technology is changed by the technology provided by the invention, the weaving effect of middle / high-grade yarn and high branch yarn is increased; the quality of fiber carding is not influenced after the fixed weight is increased; the production efficiency is increased; and the problem of insufficient card sliver supply is solved.

Description

Technical field:

[0001] The invention relates to the technical field of production technology of high-grade woven yarns, in particular to a process for quantitatively producing high-grade woven yarns by raw sliver weights and quantitatively produced by a blowing and carding combined carding machine of Zhengzhou Textile Machinery Co., Ltd. Background technique:

[0002] Cotton yarn has a wide range of uses. It can be used as yarn for weaving or knitting. Especially combed yarn can be used to produce textiles with high quality requirements, such as high-end sweaters and fine poplin. Cotton yarn can also be used to produce special Industrial electrical yellow wax cloth, tire cord fabric, high-speed sewing thread and embroidery thread, etc. In recent years, with the continuous progress and development of textile technology, the quality of cotton yarn in various countries in the world has been continuously improved. High-grade textiles have put forward continuously improving req...
