FIELD: chemistry.
SUBSTANCE: invention relates to field of processing synthetic fibres and deals with method of increasing physical and mechanical characteristics of aramide threads, containing 5(6)-amino-2(p-aminophenyl)-benzimidazole. It includes processing of threads from aromatic polyamides, containing 5(6)-amino-2(p-aminophenyl)-benzimidazole, in chamber of generator of ultrahigh frequencies by UHF-radiation. Heating of threads is performed under tension or in free state. After that, air-conditioning of threads is carried out.
EFFECT: improvement of physical and mechanical properties of threads from aromatic polyamides.
