What are the uses and functions of core-spun yarn?

Core-spun yarn is a new type of yarn composed of core yarn and sheath yarn. It usually uses synthetic fiber filament (such as polyester, spandex) as the core layer and is wrapped with natural fiber or regenerated short fiber (such as cotton, wool, viscose fiber)‌
This structure enables it to combine the advantages of different fibers to achieve complementary properties.

In terms of uses, core-spun yarn is widely used. Clothing fabrics are one of the main fields, including student uniforms, work clothes, shirts, bathrobes, skirts, etc. Among them, polyester-cotton core-spun yarn can balance stiffness and moisture absorption‌

Stretch fabrics such as stretch denim, sportswear and underwear often use spandex core-spun yarn to provide good stretchability and comfort‌

Decorative fabrics such as curtains, bedspreads, tablecloths, etc. often use burnt-out core-spun yarn, which is chemically treated to form three-dimensional patterns‌

In addition, core-spun yarn is also used in sewing thread production, which requires high strength and wear resistance‌

Functionally, core-spun yarn improves fabric performance through the synergistic effect of core yarn and outer fiber. For example, polyester-cotton core-spun yarn combines the anti-wrinkle and quick-drying properties of polyester with the hygroscopicity and comfort of cotton, making the fabric easy to dye, bright in color and comfortable to wear‌

The spandex core-spun yarn gives the fabric excellent elasticity and is suitable for underwear and sportswear. At the same time, the core yarn is not exposed and the appearance is smooth‌

In terms of functionality, core-spun yarn can achieve special effects through fiber combinations, such as using chemical differences to make burnout fabrics, or using antibacterial fibers, far-infrared fibers, etc. to develop health-care functional products‌
