FIELD: chemistry.
SUBSTANCE: filter is made of nonwoven fabric and/or injected filter structures or sheets, i.e. produced after processing the synthetic artificial fibres. At first fibres are processed with antibacterial compounds and sliced to monothreads. Natural, artificial, synthetic, metal fibres or their mixtures are used. Web and felt are formed from these threads. Required number of nonwoven fabric layers is connected, thereafter processed, sliced and rolled.
EFFECT: extended application of aforesaid filters, improved wetting and filtering ability ensured.
