Abstract

It is the object of the invention to propose a method for open-end rotor spinning, wherein the formation of cover yarn, in particular the so-called "belly bands", is at least appreciably reduced.In accordance with the invention, the fiber flow exiting a fiber guide channel has a directional component in the direction of rotation of the rotor, while the yarn leg (3) extending, from the draw-off nozzle to the rotor groove, is curved opposite the direction of rotation of the rotor, at least near the rotor groove (1), during the spinning process. The creation of this direction of curvature of the yarn leg (3) takes place during the piecing process.

Description

Technical field

[0001] The present invention relates to an air spinning method, in which fibers to be spun are fed into the spinning cup through a fiber guide channel and are collected in the spinning cup groove with the largest inner diameter of the spinning cup, and the fibers are rotated in a spinning cup through the rotation of the spinning cup. The so-called insertion zone is twisted into the yarn end and is led out as a finished yarn through a central yarn guide tube arranged approximately in a plane with a rotor groove. Background technique

[0002] The development of air spinning can be traced back to a long time ago, and this method was only put into industrial application in the 1960s. Not only in the peripheral area, that is, in the peripheral area where the fiber sliver is transported, the single fiber is opened, the single fiber is sent to the spinning cup, and the fiber is drawn and wound, but also in the core area of ​​the fiber, that is, in the spinning cup Among ...
