FIELD: process engineering.
SUBSTANCE: invention relates to filtration materials for cleaning hydrocarbon fuels and oils of mechanical impurities. Proposed material comprises carcass canvas made up of nonwoven material and fibrous layers made from synthetic staple fibers arranged on both sides of said canvass. Carcass nonwoven canvass and fibrous layers are made from the mix of polyether fibers and bicomponent polyether fibers at the ratio of 50:50 wt %. Said carcass canvass represents a matrix with pore sizes varying from 25 to 60 mcm. Relation between pore sizes of nonwoven filtration material and matrix varies from 1:2 to 1:5.
EFFECT: rated filtering capacity of 5 to 30 mcm.
