FIELD: technological processes. ^ SUBSTANCE: invention is related to the field of fibrous filtering materials. Filtering material is suggested for respirators, which contains working layer of fibres with diametre of 1-10 mcm produced by method of electrostatic moulding from solution containing 6-16 wt % of polycarbonate in mixture of dissolvents that consists of dichloroethane and methylene chloride with their mass ratio of (1-5):(9-5), accordingly, and having surface density of 30-60 g/m2. Respirator is made with application of produced material. ^ EFFECT: improved mechanical strength of material and products on its basis. ^ 4 cl, 1 dwg, 2 tbl |
