FIELD: machine building.
SUBSTANCE: invention relates to method of obtaining antistatic polypropylene fibres with improved mechanical properties, which can be used in machine building, chemical, electrical engineering and light industry. Proposed method consists in fact that extruded fibres based on polypropylene (PP) filled with carbon nano particles, are subjected to eightfold orientation drawing. Drawing is carried out in two stages: at first fibre is drawn in four times, then two times at temperature of 150 °C.
EFFECT: invention allows to produce polypropylene composite fibres with improved physical and mechanical properties.
