Embodiment Construction

[0036] Specific examples of the present invention are given below. The specific embodiments are only used to further describe the present invention in detail, and do not limit the protection scope of the claims in this application.

[0037] In the same way as compact siro spinning, four rovings are simultaneously fed into the ring spinning frame in parallel to spin 45tex yak cashmere core-spun yarn, and then the spun core-spun yarn is woven into double-ribbed knitted fabric with a computerized flat knitting machine. After the finished knitted fabric is dedimensionalized, after the final product is dedimensionalized, a knitted fabric with low fiber arrangement density, high yarn bulkiness and hollow yarn structure is formed.

[0038] The manufacturing process is as follows:

[0039] In the first step, the water-soluble vinylon staple fiber is opened with a wool machine, and then carded to obtain a raw sliver, which is drawn through the first and second draws, and finally spun ...

Abstract

The invention discloses a production method of yakwool hollow yarn. The production method comprises the following steps: taking vinylon as core yarn and yakwool as covering yarn, respectively spinning vinylon roving and yakwool roving by use of semi-worsted spinning, feeding four roving into a ring spinning frame in parallel at the same time by following compact siro spinning, wherein the yakwool roving is three, and the vinylon yarn is one; feeding the vinylon roving from the left second hole of a four-hole horn mouth so that the vinylon roving is centered; therefore, the effect of covering the yakwool on the vinylon can be well realized. By use of the yarn method disclosed by the invention, the process of spinning the core yarn as the spun yarn is omitted, the process flow is shortened, and the effect of being similar to core spun yarn is achieved. And meanwhile, the yakwool only needs to be processed as roving, the procedure that the yakwool is hard to be processed as the spun yarn due to short and thick characteristics is avoided. Finally, a hollow yarn structure is formed by the yarns in the fabric after the dissolution by use of the fabric dissolution method, the air is trapped, the warm keeping coefficient is increased, and the formed fabric has the features of being light and thin, soft, and moisture-absorbing and quick in drying.

Description

technical field [0001] The invention relates to the field of new textile yarns, in particular to a production method of yak cashmere hollow yarn. Background technique [0002] Yak cashmere fiber is pure and environmentally friendly, with soft luster, strong elasticity, and smooth handle. Compared with cashmere, it has better elasticity, moisture absorption and release, wear resistance and pilling resistance, and fiber strength. The fabric made of it has the characteristics of softness, comfort, high-grade elegance, etc., showing a simple, natural style and elegant and free and easy inner temperament. It is a rare natural textile raw material. [0003] Warmth retention is one of the important indicators for autumn and winter clothing. With the development of the fabric market, people's requirements for fabrics are gradually developing in the direction of fashion and comfort. And traditional autumn and winter clothes are too heavy, so the development of light and thin warm fa...
