Abstract
The invention relates to a method for the texturing of endless yarn by means of a texturing nozzle having a continuous yarn duct into which compressed air at a pressure higher than 4 bar is blown in the direction of the yarn conveyance, whereby the yarn duct is preferably conically widened at the outlet end with a widening angle larger than 10° for generating a supersonic flow. The invention furthermore relates to a texturing nozzle for the texturing of endless yarn with a continuous yarn duct having an inlet end, a central, preferably cylindrical portion with an air supply orifice as well as a preferably conical outlet end with a widening angle larger than 10°, but smaller than 40°.

A method for treating yarn, comprising:
- conveying yarn through a yarn duct defined by a texturing nozzle;
- supplying compressed air into the yarn duct substantially in a conveying direction of the yarn,
- wherein the compressed air is supplied at a pressure of more than 4 bar and at an angle of more than 48 degrees with respect to a longitudinal axis of the yarn duct.
An apparatus for treating yarn, comprising:
- a texturing nozzle defining a yarn duct having an inlet and a longitudinal axis;
- and
- at least one compressed air supply orifice disposed so as to supply compressed air into the yarn duct substantially in a direction of a conveying direction of yarn through the yarn duct and at an angle of more than about 48 degrees with respect to the longitudinal axis of the yarn duct.
