Classification of core spun yarn by product use

Core spun yarn for sewing

Core spun yarn for rags

Elastic fabric (including knitted fabric woven fabric) core spun yarn

Functional, high-performance fabric core spun yarn, etc.

Fancy core spun yarn (such as hollow core spun yarn, color core spun yarn, sirofier core spun yarn, slub core spun yarn, etc.)

Two

Classification by core filament

Rigid core spun yarn: polyester, acrylic, vinylon (including water soluble vinylon), nylon, etc

Elastic core spun yarn: spandex, PTT fiber, PBT fiber, etc. Spandex is widely used.

Three

Classification by sheath fiber

Usually cotton, wool, silk, hemp (including ramie, flax, hemp, etc.), colored cotton other natural fibers;

Viscose fiber, modal, Tencel, soybean fiber, milk fiber, bamboo fiber, polyester fiber, acrylic fiber all kinds of colored chemical fiber can be used for covering fiber of core spun yarn.

Four

Classification by spinning equipment

Ring spinning, rotor spinning, friction spinning, air-jet spinning so on can be equipped with core spun device to produce various core spun yarn.

Characteristics of core spun (dref-Ⅲ) core spun yarn

It is suitable for wide spinning range, high yarn strength, even evenness less hairiness. It can also be used for wrapping cheap fibers with high quality fibers reducing cost.

Characteristics of core spun air-jet yarn

It has good spinnability, even sliver, less hairiness good covering effect of core spun yarn.

Characteristics of rotor spinning core wrapping

The core spun yarn has the advantages of wide spinning range, short technological process, high production efficiency, stable structure, even sliver, less hairiness good bulkiness. In the spinning process. Because the filament is twisted, so there is no twist shrinkage, so the rotor spun yarn is more likely to maintain the strength the core part.
