Multi-functional nozzle for spinning machine

By generating vortex flow and negative pressure suction within the nozzle channel through a multi-functional nozzle, the contradiction between strength and speed in existing spinning methods is resolved, enabling efficient production of high-quality true twist yarn. It combines the advantages of ring spinning and rotor spinning and is suitable for various types of textile machines.

AI Technical Summary

Technical Problem

Existing spinning methods struggle to achieve high spinning speeds and a wide range of yarn counts while maintaining high strength and uniformity. Furthermore, different spinning methods have their own advantages and disadvantages; for example, ring spinning and rotor spinning present a trade-off between strength and uniformity.

Method used

Employing a multi-functional nozzle, it generates vortex flow within the nozzle channel, combined with annular slits and a fluid guide design, to achieve fiber rotation and negative pressure attraction, producing true twisted yarn that integrates the advantages of ring spinning and rotor spinning.

Benefits of technology

It produces true twisted yarn with high strength and uniformity, almost no belly band or wrapped fibers, suitable for a wider range of yarn counts, and can be produced at higher spinning speeds, simplifying or replacing the traveler system.

Abstract

The invention relates to a multifunctional nozzle for a spinning machine, by means of which at least one improved true twist yarn can be produced. The multifunctional nozzle also offers the possibility of producing a true twist yarn, in which the advantages of a free-end yarn can be at least partially combined with the advantages of a ring yarn. To this end, the multifunctional nozzle comprises a nozzle channel which is arranged in a nozzle housing and which is open on one side, in which a vortex flow can be produced. Furthermore, a nozzle body which is designed to be shorter than the nozzle channel is provided, which has a through passage for a thread or a fibre strand, wherein an annular gap with at least one constriction is formed in the nozzle channel, which is constricted on both sides to the constriction. The constriction is arranged downstream of a fluid inlet which opens into the nozzle channel. Furthermore, a hollow body-like flow guide for fluidically guiding a thread or a fibre strand between the annular gap and the open end of the nozzle channel is provided, wherein the annular gap is formed between the nozzle body and the nozzle housing and / or the flow guide.
