Document Type and Number:
Japanese Patent JP5623052
Kind Code:
B2
Abstract:
Provided is a liquid-permeable nonwoven fabric having improved in air permeability in the thickness direction thereof, formed on its surface with ridges and troughs extending in parallel to each other in one direction. A nonwoven fabric 1 formed of thermoplastic synthetic short fibers 2 fused together is formed on its upper surface 3 with ridges 6 and troughs 7 extending in parallel to each other in a longitudinal direction. In a cross section of each ridge 6 taken in the transverse direction B, the ridge 6 includes opposite lateral regions 22, 23 in which the short fibers 2 are densely distributed and a central region 21 defined between the opposite lateral regions 22, 23 and in which the short fibers 2 are sparsely distributed. The short fibers 2 in the central region 21 include short fibers 2a in a crest 12 of the ridge 6 adapted to connect the opposite lateral regions 22, 23 to each other. This invention also discloses a method for manufacturing of the nonwoven fabric 1.
