Air spinning machine and method for operating an air spinning machine

Abstract

The invention relates to a method for operating an air spinning machine, whereas the air spinning machine features at least one spinning unit with one spinning nozzle (2) for producing a yarn (6), whereas, during the operation of the spinning unit, the spinning nozzle (2) feeds a fiber composite (3) through an inlet (4) and in a predefined transport direction (T), whereas the fiber composite (3) within a vortex chamber (5) of the spinning nozzle (2) receives a twist with the assistance of a vortex air flow, such that a yarn (6) is formed from the fiber composite (3), which ultimately leaves the spinning unit (2) through an outlet (7), whereas, with the assistance of at least one sensor system (11), the yarn (6) leaving the outlet (7) is monitored with regard to defined yarn flaws (26), and whereas the production of yarn (6); is interrupted upon the detection of a corresponding yarn flaw (26). In accordance with the invention, it is proposed that, between the detection of the specified yarn flaw (26) and the interruption of yarn production, at least one cleaning process is carried out from time to time, during which an additive (9) is fed to the spinning unit and is applied to the fiber composite (3) and / or the yarn (6) produced from the fiber composite (3) and / or on parts of the spinning nozzle (2). Moreover, an air spinning machine for carrying out the method is proposed.

Description

technical field [0001] The invention relates to a method for operating an air-jet spinning machine, wherein the air-jet spinning machine has at least one spinning station with a yarn nozzle for producing yarn, wherein during the operation of the spinning station The fiber strands are fed through the inlet and in a predetermined delivery direction to the yarn spray nozzle, wherein the fiber strands are twisted inside the vortex chamber of the yarn spray nozzle by means of the vortex air flow, so that a yarn is formed from the fiber strands, The yarn finally leaves the yarn nozzle through the outlet, wherein the yarn leaving the outlet is monitored for defined yarn defects by means of at least one sensor device, and wherein the yarn flow is interrupted when a corresponding yarn defect is detected. manufacture. [0002] Furthermore, an air-jet spinning machine is proposed which has at least one spinning station with a yarn nozzle for producing a yarn from a fiber sliver fed to t...

AI Technical Summary

Problems solved by technology

[0009] However, the disadvantage of the last-mentioned solution is that the yarn with additives during the cleaning process usually does not meet the quality specifications, because the yarn properties are negatively affected by the non-negligible amount of additives and the contaminants contained. influences
