Compact spinning process

from Wikipedia, the free encyclopedia

The compact spinning process (also known as compression spinning ) is a ring spinning process with a modified drafting system for combining (compacting) the fiber ribbon and for reducing or suppressing the spinning triangle before spinning.

As a result, the individual fibers are better integrated into the yarn and stand out less from the thread. Compared to conventional ring yarns, the result is a greatly reduced hairiness and improved tear resistance, which leads to less lint and lower energy consumption in further processing, such as weaving , since today's looms work with air nozzles and the lower hairiness creates less turbulence.

Techniques of compaction

  1. Pneumatic : the fiber section is brought together with negative pressure on a suction slot and thus held together before it passes the clamping point.
  2. Mechanical : the fibers are fed through a funnel before they pass the clamping point for twist distribution at the drafting system exit.

Both methods allow spinning with a reduced twist coefficient compared to conventional yarn. The pneumatic system is more common.

The process is most often used with cotton , but also with worsted and man-made fibers , with man-made fibers usually already having a low degree of hairiness.

Others

It should be noted that a variant of the melt spinning process for synthetic fibers, in which the units are arranged horizontally and thus require less space and investment, is also referred to as the compact spinning process.
