Abstract
A monofilament yarn (10) has a polygon cross-section having a width and a height, which width is greater than the height, and four corners (11, 12, 13, 14) of which the first two opposite corners (11, 13) have angles of over 90 degrees, and the second two opposite corners (12, 14) have angles under 90 degrees, said width being 0.1 to 3 mm. The rounded first two opposite corners have a radius of 0.1 to 0.15 mm, and the rounded second two opposite corners have a radius of 0.075 to 0.1 mm. The yarn may be used to fabricate an industrial textile, which may be a papermaking fabric such as a dryer fabric or a forming fabric, or a filter fabric, such as a disc filter, a horizontal vacuum belt filter, a belt filter press, a twin wire press, a drum filter, a pan filter, a gravity table or a filter press.
