Abstract

The invention relates to an air-injection vortex-spinning groove-shaped self-twist hollow spindle which comprises a fiber inlet (1), a yarn forming channel (2), a circumferential step groove (4), conical top plane arc grooves (5) and conical top wall face spiral grooves (3), wherein square groove bodies on a conical top plane of the hollow spindle are arc; included angles between the conical top wall face grooves and a horizontal direction are 20-40 degrees; the circumferential groove is step-shaped; and the quantity of steps is 1-3. According to the spindle, positive pressure bonded between a fiber at a free end and a wall face of the hollow spindle in a spinning process can be increased, and a friction force between the fiber and the wall face is increased, so that the twisting possibility of the fiber is improved, a cohesive force between the fibers in a yarn is increased, and the strength of the yarn is improved finally; in addition, the loss of the fibers can be reduced; and a use ratio of the fibers can be increased.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a grooved self-twisting hollow ingot for air-jet vortex spinning. Background technique [0002] Since the development of air-jet vortex spinning technology in 1995, it has quickly occupied the peak of spinning technology with its high-speed yarn forming speed and outstanding yarn properties. However, defects such as many details and low strength of air-jet vortex spinning yarn seriously restrict the popularization and application of its products. The main reasons are as follows: 1. In terms of processing method, the efficiency of eddy current twisting is greatly improved compared with mechanical twisting, but the high-pressure airflow is easy to pull out the fibers with insufficient control force of the yarn receiving body, resulting in the loss of fibers. loss, resulting in increased detail and insufficient strength in the final yarn. At the same time, the increase of tow rat...
