Abstract

The invention discloses a ceramic rotor spinning false twisting disc and a ceramic processing method for the inner surface of the false twisting disc and belongs to the field of spinning machinery equipment. The ceramic rotor spinning false twisting disc and the ceramic processing method for the inner surface of the false twisting disc are aimed to solve the problems of non-uniform surface coating distribution, poor quality and short service life of a traditional chrome plated false twisting disc and problems of high production cost and complex technique of a powder sintering ceramic false twisting disc. The inner surface of the ceramic rotor spinning false twisting disc is plated with a layer of ceramic film. The ceramic processing method for the inner surface of the false twisting disc includes that preparing an oxide ceramic layer at the surface of the false twisting disc, wherein the chemical ingredient of the generated ceramic layer is oxide which is same with the chemical ingredient of the false twisting disc produced through a ceramic powder pressing sintering technique; remelting and refining the ceramic layer, wherein the refined surface is uniform and wearable, and the service time of the false twisting disc on equipment is prolonged. The ceramic rotor spinning false twisting disc is suitable for spinning various materials.

Description

technical field [0001] The invention belongs to the field of spinning machinery and equipment. Background technique [0002] Compared with ring spinning, open-end spinning (also called rotor spinning) has the advantages of short process flow, large package capacity, high speed, high output and high labor production efficiency. Among the methods, it is a spinning technology with the most mature technology, the fastest development and the most extensive application. As one of the key core components of the open-end spinning machine, the false twist disc uses the high-speed rotation of the rotor to generate strong friction with the yarn formed in the rotor, and produce a false twist effect on the yarn. Although the false twist action of the false twist disc does not change the design twist of the finished yarn, the dynamic twist of the yarn before and after the peeling point in the rotor condensation tank increases, thereby increasing the peeling point and making the weakest l...
