Problems solved by technology

This type of high-count woolen yarn is costly; secondly, the key point is that it cannot meet the needs of woven product manufacturing, mainly because the yarn strength and yarn creep resistance are poor, so most of them are used as knitting yarns. Diffi

Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment.

[0024] 1. Selection of raw materials

[0025] In terms of raw material application, semi-worsted products can not only process and produce natural fibers such as cotton, velvet, wool, hemp, silk, etc., but also produce a variety of chemical fibers including new functional fibers; not only pure spinning with a single component , but also suitable for blending of various components and different proportions. Whether the yarn it produces is applied to worsted fabrics, woolen fabrics, or knitted sweaters and T-shirts, the product style is unique.

[0026] Selection of wool for semi-worsted spinning: choose sheep wool, Australian wool tops, cashmere, etc. according to the needs of the product.

[0027] Index requirements: Fineness: 16.5~20μm

[0028] Contain crude: ≤0.3%

[0029] Impurities: ≤0.5%

[0030] Short fiber: ≤20%

[0031] Color: White.

[0032] In order to obtain fibers ...

Abstract

The invention relates to a wool semi-worsted spinning process, including fearnaughting, feeding by a FB001 automatic feeding bucket, carding by a FB201 carding machine, drawing by a A272 drawing machine, treating by a A456G fly frame machine, spinning by a A513W spinning machine, cheese winding by an automatic winding machine, twisting by a twisting machine, two-for-one twisting by a two-for-one twisting machine or the like. The manufacturing apparatus is composed by combining a wool spinning apparatus with a cotton spinning apparatus. The process has advantages of: (1) creatively reconfiguring and modifying by introducing cotton spinning apparatus and process, so as to spin woolen short fiber into high count semi-worsted yarn; (2) the spinning process is comparative to ordinary cotton carding, but simplified in process, and lower in cost; (3) drawing process spinning is adopted, cotton material mixing, carding and combined drawing of cotton spinning are introduced, so that spun yarns are uniform in color, mixed uniformly, bright and clean on surface, loose in hand feeling, and soft; feature of the product is between the worsted spinning and the woollen spinning; (4) the process is relatively adaptive to raw material, flexible in yarn number, easy for technology diffusion, low in equipment investment, small in occupation.

Description

technical field [0001] The invention relates to a spinning process in the textile field, in particular to a wool semi-worsted spinning process between worsted wool spinning and carded wool spinning. Background technique [0002] Light and thin semi-worsted products are products that fill the gap between slub and worsted wool yarns. In the wool spinning industry, the development of such products is mainly restricted by the limitation of spinning equipment and technology. [0003] Most of the general woolen spinning equipment can spin less than 20 counts. Even advanced imported woolen equipment can spin more than 20 yarn counts, but the requirements for raw materials are extremely high. Even if high-count imported Australian For wool tops or high-quality cashmere, a slightly higher yarn count also requires a large proportion of chemical fibers to support the spinning strength. This type of high-count woolen yarn is costly; secondly, the key point is that it cannot meet the ne...
