PROVIDED ARE A NONWOVEN-FABRIC SHEET (1) 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 (13) COMPRISING FIBERS HAVING LATENT CRIMPING PROPERTIES AND A WEB (16) COMPRISING HEAT-FUSIBLE FIBERS, EJECTING A FLUID FROM A PLURALITY OF NOZZLES ARRANGED IN THE WIDTH DIRECTION, WHILE CONVEYING THE STACK, TO FORM RIDGES AND GROOVES, 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.
