METIER A FILER A JET D'AIR ET PROCEDE DE FONCTIONNEMENT D'UN TEL METIER A FILER A JET D'AIR

摘要

The invention relates to a method for operating an air-jet spinning machine, wherein the air-spinning machine has at least one spinning station with a spinneret (2) for producing a yarn (6), wherein the spinneret (2) during operation of the spinning station a fiber strand (3) via an inlet (4), wherein the fiber structure (3) within a vortex chamber (5) of the spinneret (2) by means of a fluid vortex receives a rotation, so that from the fiber structure (3) a yarn (6) is formed, which is the spinneret (2) finally leaves via an outlet (7), and wherein the spinning station during the operation of the air spinning machine with the aid of an additive supply (8) at least temporarily an additive (9) and fed to the fiber structure (3) or parts of the spinneret and / or the yarn (6) is applied. According to the invention, the yarn (6) leaving the outlet (7) is monitored with respect to at least one physical parameter with the aid of a sensor system, based on at least one measured value supplied by the sensor system (11) and correlated with said parameter it is determined whether and / or how much additive (9) has been applied to the fiber structure (3) or to the yarn (6) produced therefrom and passing through the sensor system (11). In addition, an air-spinning machine for carrying out the method is proposed.
