FIELD: chemistry.
SUBSTANCE: threads are formed from a molten mixture of propylene and powdered polytetrafluorethylene in amount of 2-4% of the weight of polypropylene. The powder is a mixture of particles with size of 100-900 nm, which is obtained through thermogas dynamic destruction of polytetrafluorethylene.
EFFECT: improved processibility of freshly formed fibres and ready threads.
