Problems solved by technology

In the prior art, in order to improve the false twisting efficiency of the false twisting disk, the arc surface of the false twisting disk is usually processed on the false twisting disk, and generally grooves are engraved on the curved surface of the false twisting disk (the false twisting disk does not penetrate through the holes). The upper and lower bottom surfaces) or protrusions increase the roughness of the arc surface of the false twist disc, thereby increasing the friction of the yarn on the surface of the false twist disc, but only relying on changing the shape of the false twist disc arc The false twisting efficiency of the twist disc is limited, and when spinning some special yarns, the false twisting effect is general or limited
And when grooves are carved on the curved surface of the false twisting disc, dust or impurities will accumulate inside the grooves after using for a long time, thereby reducing the service life and false twisting efficiency of the false twisting disc

Abstract

The invention discloses a rotor spinning false twister. Narrow slits penetrating a cambered surface are formed in the cambered surface of a false twister body and connected with external fans, and air exhaust functions are achieved. When yarns are spun in a rotor spinning manner, the yarns can be adsorbed on the narrow slits by external negative pressure, friction action among the spun yarns and the cambered surface of the false twister body can be increased, so that false twisting action of the false twister is enhanced, and end breakage is decreased when the yarns are spun in the rotor spinning manner. The rotor spinning false twister can effectively solve the problem of end breakage in rotor spinning of combed noil yarns below 14.7tex, and can help enterprises to effectively upgrade industries and save production cost.

Description

technical field [0001] The invention belongs to the field of spinning equipment and relates to a rotor spinning false twist disc, in particular to a rotor spinning false twist disc with narrow slits on the surface. Background technique [0002] Rotor spinning is also called air-end spinning in our country. It is a new type of spinning technology and belongs to the category of open-end spinning technology. Due to the advantages of high production efficiency, good yarn evenness, short process flow, good working environment and high degree of automation, rotor spinning is currently the most popular new spinning form. Rotor spinning has become more popular in my country, and its total production of cotton yarn is second only to ring spinning. Therefore, rotor spinning also has a greater influence in the spinning industry and plays a pivotal role. [0003] During cotton spinning, the sliver produced by the carding machine will have many defects in quality, such as the sliver co...
