Abstract

The invention discloses a vortex spinning nozzle device, which comprises a nozzle body in a hollow tubular structure. The nozzle body is axially provided with a front vortex chamber, a middle vortex chamber and a rear vortex chamber in sequential connection along the nozzle body. The front vortex chamber and the middle vortex chamber are externally provided with an annular airflow passage which isprovided with air inlets; the annular airflow passage is connected with the front vortex chamber through first spray holes and connected with the middle vortex chamber through second spray holes, andthe first spray holes and the second spray holes are in straight hole structures. By the three-section nozzle structure, vortex airflow is formed through matching of the first spray holes and the second spray holes, high airflow strength and high airflow operating stability are realized, uniform distribution of yarn fibers is benefited, fiber wrapping and twisting effects can be improved, stablespinning effects are obtained, tangling of the fibers on a guide needle can be effectively avoided, and low fiber falling rate and excellent yarn forming effects are realized.

Description

technical field [0001] The invention relates to the field of vortex spinning, in particular to a vortex spinning nozzle device. 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 utilizes 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. [0003] The mechanism of air-jet vortex spinning: the compressed air flow forms a large negative pressure at the nozzle inlet, and the parallel fiber bundles conve...
