Abstract

The invention relates to a hollow ingot for spinning of vortex spinning equipment, and belongs to the technical field of vortex spinning. The hollow ingot comprises a hollow ingot body, a yarn guide hole, a doffing tube and a yarn inlet hole. The hollow ingot body is hollowed inside and is further provided with the yarn guide hole in the axial direction, and the yarn guide hole penetrates throughthe hollow ingot body. The yarn inlet hole is formed in the front end of the yarn guide hole. The rear end of the hollow ingot body is further connected with the doffing tube. The hollow ingot for spinning of the vortex spinning equipment is simple and reasonable in structure, the yarn forming effect is good, the winding effect of formed yarns is good, the core yarn exposure phenomenon is avoided,yarn levelness is achieved and quality is good.

Description

technical field [0001] The invention relates to a hollow spindle for spinning by vortex spinning equipment, belonging to the technical field of vortex spinning. Background technique [0002] Vortex spinning is developed on the basis of air-jet spinning. It uses a fixed vortex spinning tube to replace a high-speed rotating spinning cup for spinning. Air-jet vortex spinning uses the rotation of the air to make the long fibers gather towards the center of the yarn, and the short fibers are scattered and covered in the outer layer. This unique production method can not only produce core-spun yarns, but also produce double-structured yarns with different fiber lengths and shrinkages. It can spin rich and colorful special yarns with less hairiness, high density, and good coolness. , Good washing resistance, good moisture retention and bulkiness. Existing vortex spinning tubes include components such as vortex tubes, guide needles, and hollow spindles. During the yarn forming pr...
