FIELD: chemistry.
SUBSTANCE: 10-50 wt % portion of granules is held before moulding in a micellar solution containing silver nitrate, sodium bis(2-ethylhexyl)sulphosuccinate, water and isooctane in ratio of (g/l) (0.11-2.75):(30.0-120.0):(2.0-30.0):(539.9-659.2), respectively. Simultaneously, radiation treatment is carried out with total dose of absorbed energy of 1.3-6.0 MRad, with subsequent post-radiation holding to silver content 0.002-0.010 wt % in the granules. Treated granules are mixed with the remaining portion of granules of the same polymer and the moulded from the melt.
EFFECT: invention enhances protective biocidal properties of synthetic fibres, increases stability of biocidal activity during wet processing, using minimum amount of silver.
