FIELD: technological processes.
SUBSTANCE: method includes extrusion of polymer melt, its pressing-out via pressing-out facility, formation of meshy material and its orientation. Extrusion of polymer melt at 180-265°C is carried out via flat-die draw plate to prepare flat tape. Formation of meshy material is carried out by means of tape supply to three-shaft calender, after that tape with temperature of 90-110°C is cooled down to 60-70°C and is subjected to perforation. Perforated tape is heated up to softening temperature, and longitudinal orientation is carried out. Transverse orientation of perforated tape that is heated up to softening temperature is performed. Subject of invention also includes production line and meshy polymer material, which has been prepared in accordance with the method described, and also produced in production line.
EFFECT: preparation of meshy polymer material by the simplest method and usage of more compact equipment.
