摘要:
Provided are a nonwoven-fabric sheet having a high liquid permeation rate and a process for producing the sheet. The nonwoven-fabric sheet comprises two layers, a first layer (4) and a second layer (5), and is characterized in that the first layer (4) has a plurality of ridges (2) and grooves (3) which extend in parallel in the lengthwise direction, that the first layer comprises heat-fusible fibers and the second layer comprises crimped fibers, and that the sheet has an average fiber angle of 70 or less in a cross-section parallel to the lengthwise direction. The nonwoven-fabric sheet can be produced by stacking a web comprising fibers having latent crimping properties and a web comprising heat-fusible fibers, ejecting a fluid from a plurality of nozzles arranged in the width direction, while conveying the stack, to form ridges (2) and grooves (3), heating the stack using a means that reduces resistance against the crimping properties of the fibers having latent crimping properties, thereby crimping the fibers having latent crimping properties, and then fusion-bonding the heat-fusible fibers.
