FIELD: textile industry. SUBSTANCE: method involves producing fibrous cloth on roll-type carding machine with mechanical or aeromechanical web converter; compacting cloth on needle puncher and subjecting to thermal pressing on hot calender rolls at temperature of 90-110 C and processing time of 1-2 min. Cloth is produced from biological component fibers with core melting temperature of 180 C and outer layer melting temperature of 110 C. Method is used for producing nonwoven materials for manufacture of filters. EFFECT: simplified method and improved filtering properties of filtering devices manufactured from cloth. 2 cl
