The paper Presents a disk tribometer installation and allows to determine the antifriction properties of machine-building composite antistatic-heat-conducting polymer materials working in interaction with the fibrous mass (raw cotton). A method for determining the friction force, temperature and electrostatic charge values arising in the friction zone is developed. The friction of the fibrous material is carried out on the flat surface of the rotating disk sample from the material under study at specified clamping pressures and sliding speeds. Values of friction forces, temperatures and values of electrostatic charges of the tested sample in a zone of friction with cotton-raw are measured by means of sensors.
