FIELD: chemistry.
SUBSTANCE: invention relates to chemistry of high-molecular compounds, namely to continuous aramid fibre and a method for processing thereof, as well as to textile fabrics and protective clothing. Aramid fibre processing process includes 2 stages. First, combining aramid fibrous material containing discontinuous aramid fibres with sulfuric acid to obtain a spinning solution containing an aramid, Thereafter, spinning solution containing aramid is processed into continuous aramid fibre. Proposed approach provides an efficient processing process, in which it is possible to use a wide range of aramid materials in various forms as raw materials.
EFFECT: described process leads to obtaining high-quality continuous aramid fibres, which can be used in a wide range of applications and which can have mechanical properties comparable to primary aramid fibres.
