Abstract
A spinning unit of an air-jet spinning machine for the spinning of a fiber composite has a pair of delivery rollers and a spinning nozzle, whereas the spinning nozzle has a yarn formation element and a fiber guide element. The fiber guide element has a front turned towards the pair of delivery rollers and an end turned away from the pair of delivery rollers. The fiber composite is fed to the spinning nozzle with the pair of delivery rollers, and is introduced into the spinning nozzle through the fiber guide element, and subsequently a yarn is formed from the fiber composite through the yarn formation element. A tool for feeding an additive to the fiber composite is provided between the pair of delivery rollers and the end of the fiber guide element.
