What are the classification of yarns?

- Jul 26, 2019-

According to the structure of the yarn

Short fiber yarn

A yarn made by spinning cotton, wool, hemp, silk or chemical short fibers.

Features: fluffy structure, full appearance, good warmth and comfort.

Filament yarn

A yarn made from filaments.

Features: smooth, uniform, good gloss, high strength.

Composite yarn

A yarn processed from a single yarn or a filament bundle of two or more different traits. Has a composite effect and a special appearance.

According to the type of fiber that makes up the yarn

Purely spun yarns such as cotton yarn, wool yarn, viscose yarn.

Blended yarns, such as: polyester 65/cotton 35, polyester 50/cotton 33/jin 17.

According to spinning process, spinning method

According to the spinning process

Carded yarn, combed yarn, woollen yarn, etc.

According to the spinning method

Ring spun yarn, air-jet spun yarn, air-jet spun yarn, friction spun yarn, electrospun yarn, compact spun yarn, and the like.

Ring spun yarn

Features: Both ends of the strip are held, and there is a twisted triangle area. The twisting and winding are completed at the same time. The yarn structure is tight, the yarn strength is high, the hairiness is small, and the fiber straightness is high.

Air spinning yarn

Features: It has the advantages of fast spinning speed, large yarn roll, wide adaptability and simple mechanism. It does not need the advantages of spindle, steel ring and wire ring, and can double the yarn yield.

The air-spun yarn has good uniformity, less hairiness and good wear resistance, but the yarn strength is low and the elongation is large.

Air-jet spinning yarn

Features: The high-speed jet vortex generated by compressed air is applied to the gauze by false twisting, which is spun and twisted.

The core of the air-jet spinning yarn is almost flawless, the outer fiber is randomly wrapped, the yarn is loose and the strength is low.

According to the length of the fiber constituting the yarn

Cotton yarn, wool yarn, medium and long fiber yarn.

According to the use of yarn

1. Woven yarn: divided into warp and weft.

2, knitting yarn: generally require uniform thickness, less twist, less defects.

3, yarn for raising: requires longer fibers and less twist.

4, special industrial yarn: such as tire cord.
