True Twist

- Oct 19, 2018-

When the true twist is obtained on the sliver, the outer layer of the fiber will produce inclined spiral twist, fiber twist deformation, yarn close to each other, changing the structure of the fiber collective and mechanical and physical properties. When there is an angle of encirclement on the sliver, the fiber will have centripetal pressure on the sliver, the greater the angle of encirclement, the greater the centripetal pressure. Because of the centripetal pressure, the outer fiber is extruded into the inner layer, which increases the compactness of the yarn and the friction between the fibers, thus changing the structure and the physical and mechanical properties of the yarn. This is the essence of true twisting yarn.
