SUBSTANCE: multilayered sorption-filtering non-woven material consists of at least two sorption layers of non-woven material. The material consists of 2-4 sorption layers of non-woven material, consisting of fibres, filled with solid sorption particles, obtained from polymer solutions through aerodynamic shaping. The material also contains a reinforcing layer made from woven or non-woven material, on the outside of one or two sides of the sorption layers of the non-woven material. The layer of the reinforcing layer is ranges from 0.1 to 0.5 of the layer of the sorption layers. The ration of the diameter of the fibre of the reinforcing fabric layer to the diameter of the fibre of the sorption layers is about 6-14, 0.4-2 of the non-woven layer, and the ratio the specific surface of the reinforcing layer to the specific surface of the sorption layers is about 0.01-0.1.
EFFECT: increased physical and mechanical properties and simplification of the manufacturing technology.
