Invention patent number, 95113330.6, authorized announcement number CN1054895C, authorized announcement date on July 26, 2000; G Schaffler. Air-jet spinning machine. Invention patent number, 200580036148.X, authorized announcement number CN101044271B, authorized announcement date in 2010 June 23), that is, install air jet parts in the input or output area of ​​the front roller nip of the spinning frame, and the compressed airflow generated by the air jet parts will compress the hairy fibers on the whiskers, so that the hairy fibers can be attached to the surface of the yarn. Effective twisting and wrapping are obtained in the twisting process, thereby reducing the yarn hairiness index; or compact spinning (Wang Yijun, Hu Hongcai. Compact spinning device of ring spinning frame.

Although the fibers are condensed by the suction force of the negative pressure and the hairiness is reduced, the energy consumption is huge and the cost is increased.
However, the cost of these two methods is increased energy consumption

Abstract

The invention provides a device and method used for leveling ring spinning yarn hairiness. The device used for leveling the ring spinning yarn hairiness comprises a rough yarn feeding mechanism, a drafting mechanism and a twisting and winding mechanism. The device is characterized by further comprising a hairiness leveling mechanism, the hairiness leveling mechanism comprises a fixed frame, a stepping motor, a worm, a driving gear, a transmission gear, a leveling roller and a first yarn guiding hook, the fixed frame is located between the drafting mechanism and the twisting and winding mechanism, the first yarn guiding hook and the stepping motor are fixedly connected to the fixed frame, the worm on the stepping motor is coupled with the driving gear, the transmission gear is connected to the leveling roller in a sleeved mode, the two ends of the leveling roller are respectively connected to the fixed frame in a sleeved mode, and the transmission gear is coupled with the driving gear. The hairiness leveling mechanism is additionally arranged on a ring spinning yarn machine, so that the hairiness length is reduced, contact cohesive force among fibers is increased, the use ratio of the fibers is improved, and spinning breakage is reduced.

Description

technical field [0001] The invention relates to the technical field of cotton textiles, in particular to a high-quality, low energy consumption, less hairiness and high-strength spinning technology for cotton yarn, viscose yarn and polyester yarn. Background technique [0002] The yarn prepared by the ring spinning system accounts for nearly 50% of the yarn products in the market. The quality indicators of the corresponding yarn are mainly evenness and strength. The key to determine the quality of the above two indicators is the protruding surface of the yarn. The length control of fiber end hairiness is also the key goal of spinning process optimization in cotton spinning ring spinning system. Since the 1960s, one of the key technologies of the ring spinning system is how to reduce the hairiness index, improve the utilization rate of fibers, make the fibers more uniform in the yarn body, and increase the contact cohesion of fibers in the yarn. Thereby shortening the length...
