Compact spinning is a new spinning technology for spinning on an improved new ring spinning frame. The compact spinning technology has successfully solved the hairiness and flying flowers produced by ring spinning, and improved the strength and wear resistance of the yarn. The appearance and physical properties of the yarn have been greatly improved and improved, which is comparable to ordinary ring spinning. Compared with, it has obvious advantages in yarn quality and output.

1. The principle of compact spinning
Compact spinning (concentration spinning): A new spinning technology improved on the ring spinning frame. A fiber control zone is added before the traditional drafting device. The airflow is used to laterally condense the fiber bundles passing through the control zone, so The width of the bundle is greatly reduced. After the fiber bundle is gathered and then twisted and wound, almost every fiber of the fiber bundle can be gathered into the yarn body to form a concentrated spinning yarn with less hairiness and high strength.

2. Compact spinning equipment
So far, the compact spinning equipment that has been put into use includes foreign compact spinning, Swiss Rieter compact spinning: Suessen compact spinning from Germany, Zinser compact spinning from Germany, Toyota compact spinning from Japan, and Shirokas compact spinning.

Compact spinning classification
One is the air-concentrating compact spinning system, which mainly uses negative pressure air force to cause the fibers in the agglomeration zone to shrink laterally and converge tightly;
One is the mechanical agglomeration compact spinning system, which mainly uses mechanical force to cause the fibers in the agglomeration zone to shrink in the transverse direction and condense tightly.
