METHOD OF PRODUCING SYNTHETIC FIBRES Russian patent published in 2014 - IPC D01F11/04 D06M15/256 D01F6/00 D01F6/06 D01F6/60 D01F6/62

Abstract RU 2522338 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing synthetic fibres with high chemical resistance and water-repellent properties and low coefficient of friction. The method involves forming fibres from a molten polymer, depositing a brightening preparation, orientation drawing and heat fixing. The brightening preparation is deposited on a hot surface of freshly moulded fibres simultaneously with an aqueous suspension of polytetrafluoroethylene with concentration of 3-60 g/l. Orientation drawing is carried out with a repetition factor of 3-15.

EFFECT: high resistance of fibres to aggressive media, water-repellent properties and low coefficient of friction.
