The core spun yarn refers to a composite yarn that is combined with a core yarn and a sheath yarn; generally, the filament is used as the core yarn, and the staple fiber is the outer sheath fiber-sheath yarn.Through the combination of the outer fiber and the core yarn, the advantages of each can be brought into play, the shortcomings of both sides can be made up, and the structure and characteristics of the finished yarn can be optimized by taking advantage of strengths and avoiding weaknesses.

Classification of core spun yarns：

1 Classification by product use

Core spun yarn for sewing,

Viscose fiber, MODAL, TENCEL, soybean fiber, milk fiber, bamboo pulp fiber, polyester fiber, acrylic fiber and various colored chemical fibers can be used for the covering fiber of the core-spun yarn.

4 Classification by spinning equipment

Ring spinning, rotor spinning, friction spinning, air-jet spinning, etc. can be equipped with core-spun yarn spinning devices to produce various core-spun yarns
