Yarn classification:
① Short fiber yarn is made of short fiber (natural short fiber or chemical fiber cut fiber) by spinning, which is divided into ring-spun yarn, free-end spinning, self-twisting yarn, etc.
② Continuous filament, such as natural silk and chemical fiber filament, can be twisted or untwisted separately, smooth filament or deformed filament.
③ Short fiber and continuous filament combination yarn, such as polyester/cotton filament core-spun yarn, etc. Thread is made of two or more strands of single yarn combined and twisted.
According to the classification of spinning process, it can be divided into combed yarn, carded yarn and semi-combed yarn
According to the classification of dyeing, finishing and post-processing of yarn, it can be divided into: white yarn, bleached yarn, dyed yarn, burnished yarn, mercerized yarn, etc.
It is classified according to the yarn thickness (count), such as coarse count yarn, medium count yarn, fine count yarn and high count yarn.
According to different raw materials: pure cotton yarn, chemical fiber yarn and blended yarn
According to different spinning methods: ring spinning, rotor spinning, vortex spinning, dust cage yarn, etc
According to the twist, the twist direction is divided into: z-twist S-twist, low-twist, strong-twist yarn, end-fiber yarn, double-ply yarn, multi-strand yarn, and double-twist yarn.
