Abstract

The invention belongs to the technical field of spinning methods, and relates to a ring spinning machine with an electrostatic gathering device capable of reducing hairiness and an electrostatic gathering spinning method. The ring spinning machine is provided with the electrostatic gathering device which is arranged between a rear rubber roller and an unwinding roller; the electrostatic gatheringdevice comprises an upper tensioner, a positive charge yarn guide hook, a lower tensioner and a high-voltage power supply; the positive charge yarn guide hook is made of a conductor material and is incontact with a guide yarn unwound from the yarn coil; the positive electrode of the high-voltage power supply is connected with the positive charge yarn guide hook; and the cathode of the high-voltage power supply is connected with the ring spinning machine body and grounded. By virtue of the ring spinning machine, the yarn hairiness can be reduced, yarn strength can be improved, and yarn performance can be improved. Compared with existing negative-pressure compact spinning, electrostatic gathering spinning is more energy-saving, and the production cost of enterprises can be reduced. The electrostatic gathering device is directly added to a traditional ring spinning machine, and is simple in mechanism and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of textile methods, and relates to a ring spinning machine with an electrostatic accumulation device for reducing hairiness and an electric spinning method. Background technique [0002] Yarn hairiness causes the yarn to stick together during the weaving process, resulting in unclear shedding or even yarn breakage, which seriously affects the weaving efficiency; it also affects the clarity of the fabric texture and the smoothness of the cloth surface, and it will also cause differences in dyeing after finishing. Yarns with high quality, high tenacity and less hairiness are more and more favored by the market. Therefore, it is of great significance to reduce yarn hairiness and improve yarn quality and performance through technical processes. [0003] Ring spinning forms yarn by twisting the drafted fiber strands output at the nip of the front roller, but because the short fibers are relatively loose at the n...
