There are several spinning techniques for yarns.

There are ring spinning, air spinning, air-jet spinning, friction spinning, electrostatic spinning, compact spinning and so on.

1, different spinning methods As for the yarn structure, the structure of short fiber yarn is different from that of filament yarn, first of all, the arrangement of external and internal fibers of the yarn, and the external structure includes the appearance and surface structure of the yarn. Such as: the arrangement of fibers on the yarn surface; Hairiness of yarn; Friction coefficient of yarn; Characteristics of yarn; Wear resistance and other surface characteristics of yarn.

2. The internal structure of the yarn mainly refers to the whole cross section of the yarn body and the longitudinal arrangement of the yarn. The internal structure of fiber orientation, elongation, displacement and twist includes: the strength of yarn; Degree of fiber mixing; Bending strength; Compressibility; Toughness.
