MULTILAYER NON-WOVEN FABRIC WITH POLYAMIDE NANOFIBRES Russian patent published in 2014 - IPC A61L15/22 B82B1/00 A61L15/44 A41D13/11 

FIELD: medicine.

SUBSTANCE: what is described is a non-woven fabric consisting of several layers and comprises spot-glued carrier with polyamide nanofibres containing at least one antimicrobial substance, and a protecting coat. The polyamide nanofibres are made of polyamide and can be fixed on the carrier by means of a liquid adhesive. Non-woven fibre fabrics of the density of 15 to 90 g/m² are used as the carrier of the nanofibres and protecting coat: polypropylene, polyester, cellulose-polyester, cellulose or paper. The polyamine nanofibres contain at least one antimicrobial substance in an amount of 0.4 to 35% of nanofibre weight among: guanidines, metal nanoparticles, stabilised silver salts, quaternary ammonium compound salts.

EFFECT: material possesses antimicrobial activity, high air permeability, and fracture resistance.
