Abstract

The invention provides a fiber self-twisting hollow ingot in air-jet vortex spinning. The fiber self-twisting hollow ingot is characterized by comprising a hollow ingot body; and grooves are uniformly distributed on the outer surface of the hollow ingot body. As small grooves are distributed on the surface of the hollow ingot, the tail end of the fiber is attached to the surface of the hollow ingot under the effect of air flow and rotates; when the surface friction coefficient of the hollow ingot is increased, the tangential friction on the tail end of the fiber applied by the surface of the hollow ingot is increased, and in combination with the tangential acting force on the fiber surface applied by the high-speed air flow, a rotating moment is generated; and when the rotating moment is great enough to overcome the torsional rigidity of the fiber, the fiber generates a self-twisting effect, the fiber surface generates torsional deformation, the cohesive force of fiber is increased, and the yarn strength is improved. Through the invention, the strength of the air-jet vortex spun yarn is substantially improved, and the application range of the air-jet vortex yarn is remarkably expanded.

Description

technical field [0001] The invention relates to a special hollow spindle for air-jet vortex spinning, which is suitable for an air-jet vortex spinning machine. Background technique [0002] Air-jet vortex spinning stands out among many new spinning technologies because of its excellent performance of high speed and high output. It uses the rotating airflow to draw the yarn core through the air jet vortex cavity after being drafted by the drafting unit, and the head end enters the hollow spindle, while the free tail fiber lying on the outer surface of the hollow spindle rotates at a high speed with the rotating airflow, twisting into a Yarn, which overcomes the disadvantages of large rotary inertia force and easy wear of mechanical twisting parts in traditional ring spinning, not only greatly improves twisting efficiency and spinning speed, but also relatively reduces energy consumption, thereby reducing production costs ,Improve economic efficiency. However, the current ai...
