According to the fiber composition contained in the yarn, it can be divided into pure spun yarn and blended yarn.

(1) Pure spun yarn: a yarn composed of the same short fiber, with a single fiber, predictable yarn characteristics, simple processing, and no need to consider blending ratios or compatibility issues. Such as pure cotton yarn, wool yarn, viscose fiber yarn, acrylic yarn, polyester yarn, etc.

(2) Blended yarn: A yarn formed by blending two or more fibers. Can combine the advantages of different fibers to compensate for the shortcomings of a single fiber. Blended yarns generally list the names of each fiber in descending order of fiber content, and indicate the percentage of fiber content before or after the name; When the fiber content of each product is the same, the fiber names are arranged in the order of natural fiber, regenerated fiber, and synthetic fiber. Such as 65/35 polyester/cotton blended yarn, 50/50 wool/polyester blended yarn, 50/35/15 polyester/viscose/nitrile blended yarn, etc.

3) Twisted yarn: The yarn has high strength and elasticity, is not easily deformed, and can maintain stability during high-speed operation and long-term use. Yarn made by combining (twisting) yarns of different components, such as silk/cotton yarn twisted yarn.
