Publication number: 20240026577Abstract: A spinning element of an air-jet spinning nozzle for an air-jet spinning machine for producing a yarn from a sliver using an airflow. The spinning element of the air-jet spinning nozzle for the air-jet spinning machine and a corresponding air-jet spinning nozzle allows a particularly inexpensive, low-maintenance, and simple operation of an air-jet spinning machine without compromising the quality and strength of the air-jet spun yarn and without requiring frequent cleaning. This is achieved in that the spinning element has at least one fibre- and/or thread-guiding surface, an anti-adhesive coating being located on at least some sections of the fibre- and/or thread-guiding surface.Type: ApplicationFiled: November 24, 2021Publication date: January 25, 2024Inventors: Jochen DRESSEN, Karoline GÜNTHER, Chandrassekaran SESHAYER, Ralf SIEWERT, Thomas WEIDE
