LIQUID-PERMEABLE NONWOVEN FIBROUS FABRIC

摘要

The present invention provides a liquid-pervious fibrous non-woven fabric wherein even viscous bodily fluid can quickly permeate. The liquid-pervious fibrous non-woven fabric 1 including staple fibers 2 made of thermoplastic synthetic resin fused together is formed on its upper surface 3 with a plurality of ridges 6 and a plurality of grooves 7 extending in parallel in a longitudinal direction A and these ridges 6 and grooves 7 are arranged alternately in a transverse direction B. Height t measured from a lower surface 4 of the fibrous non-woven fabric 1 to a bottom 12 of the groove 7 is in a range of 40 to 55% of height T measured from a lower surface 4 of the fibrous non-woven fabric 1 to an apex 11 of the ridge 6. On the upper surface 3, some of the staple fibers 2 (2a) extend across the ridges 6 to the adjacent grooves 7 on each side of the ridges 6 and are, in the respective grooves 7, fused to the staple fibers 2 of a different type from the former staple fibers 2.
