Abstract

The false twist chamber has tangential air jets inlet and outlet channels with diameters 1.2 to 1.5 times smaller than the inner diameter of the chamber. The length of the channels is 25 to 150 times greater than their diameter. Feeds of 300-800 m/min and speeds of several million. rpm are ensured with the above design.
