Abstract
A method is provided to operate an air jet spinning machine, having at least one spinning unit with a spinning nozzle for manufacturing yarn, in which a fiber strand is fed to the spinning nozzle through an inlet and is imparted a twist inside a vortex chamber of the spinning nozzle by means of a swirled air current so that a yarn is formed from the fiber strand. An additive is added with an additive dispenser to the spinning unit while the air jet spinning machine is operating and applied on the fiber strand or on sections of the spinning nozzle and/or the yarn. At least one physical parameter of the yarn is monitored by a sensor system wherein, based on a measured value supplied by the sensor system correlated with the parameter, it is determined whether and/or how much additive was applied.
