Twisting

Twisting is a necessary means to give fibers a certain degree of strength and stability in appearance. Before twisting, loose fibers are generally condensed into fiber strips. After twisting, the outer fibers of the fibers are compressed towards the inner layer to generate centripetal pressure, thereby allowing the strands to obtain frictional force along the length direction of the fibers.

For long fiber bundles and strands, twisting can form a tight and stable structure that is not easily damaged by lateral external forces, making the yarn more durable. The structural forms of the resulting yarn are diverse, achieving optimal strength, elongation, elasticity, flexibility, gloss, and hand feel.
