FIELD: filtration of liquids and gases. SUBSTANCE: nonwoven fabric from random-arranged synthetic fibers has through melts at points of fiber intersections, said fibers having an elliptical loop and free fiber sections. The relation of fiber free length to twice the length of the larger half-axis of ellipse is 0,33-1·104 and the relation of fiber diameter to twice the length of the larger half-axis of ellipse is 6,6·10-5-4,0. EFFECT: improved characteristics of fabric. 1 tbl, 2 dwg
