Wool spinning: the use of compact spinning technology has realized the high branching of wool spinning yarn and single weft knitting. The worsted fabric has clear, fine and smooth texture and smooth handle, which fully exerts the fine characteristics of wool fiber. The single warp single weft tweed produced in Jiangsu Dan Mao is well received by buyers.

Editorial Reviews

At present, the varieties produced by compact spinning technology have gradually expanded from the initial cotton high count yarn to wool yarn, chemical fiber blended yarn, multi fiber blended yarn and so on. It is also suitable for the processing of regenerated cellulose fiber. In actual production, the quality of viscose, Modal, Tencel and other fiber yarn has improved significantly compared with ring spinning. Besides reducing hairiness, it has significant effect on improving yarn IPI value and dynamic test value, and has played a positive role in promoting the quality and grade of textiles.

mVS

Technical brief

Air jet vortex spinning is a new spinning technology combining jet spinning with vortex spinning on the basis of jet spinning. Although its yarn structure is different from jet spinning, it still has skin core structure. Because of its high ratio of wrapped fiber to core fiber, core twisting fibers are almost completely covered and fiber arrangement is more similar to ring spinning.

Superiority embodiment

Compared with jet spinning, jet vortex spinning has faster spinning speed, stronger yarn strength, maximum winding speed up to 450m/min, yarn strength can reach more than 80% of ring spinning, and because of uneven strength ratio, the production efficiency of air-jet vortex yarn is higher than that of ring yarn. At the same time, the jet vortex spinning has a high proportion of fiber outside, and has good performance of pilling. The yarn structure is more fluffy. Its dyeing property and moisture absorption and permeability are better than that of air-jet spinning.

Examples of application

Dezhou Huayuan uses Modal, Tencel and other new fiber yarns produced by air-jet vortex spinning technology, thereby further reducing yarn hairiness and improving yarn quality. At present, the company has developed mass scale production, mainly used for high-grade knitting products, and the quality of finished products has reached new level.

Editorial Reviews

The new fiber yarns produced by the technology have advantages in yarn post-processing, weaving, dyeing and finishing, making the product structure further develop in the direction of differentiation, diversification, serialization and high added value.

semi-worsted

Technical brief

Semi worsted technology is a new spinning technology developed independently in wool spinning and cotton spinning industry. The former spinning uses cotton spinning combing equipment to solve the problem of short fiber combing, while the latter spinning adopts worsted yarn equipment, but not through the card comber, so the production process is short and efficient.

Superiority embodiment

Semi worsted yarns can be used to blend cotton, wool, silk, hemp and special animal fibers with other new chemical fibers and all kinds of staple fibers, as long as the fibers above 25mm length can be used as semi worsted materials. The traditional woolen yarn can only produce 20Nm by spinning spindle, and ring spinning can only reach 32Nm, while semi worsted spinning technology can spin 27~102Nm yarns, thus meeting the needs of producing high-grade special animal fiber fabrics.

Examples of application

In recent years, Jiangsu arrow deer has increased the proportion of semi worsted fabric development, weaving technology and popular elements, making this kind of fashion fabric become a "new force" for enterprises to open up the market.

Editorial Reviews
