Abstract
A liquid-pervious fibrous non-woven fabric includes staple fibers made of thermoplastic synthetic resin fused together which is formed on its upper surface with a plurality of ridges, and a plurality of grooves extending in parallel in a longitudinal direction. The ridges and grooves are arranged alternately in a transverse direction. On the upper surface, some of the staple fibers extend across the ridges to the adjacent grooves on each side of the ridges and are, in the respective grooves, fused to the staple fibers of a different type from the former staple fibers.
