PURPOSE:To obtain the nonwoven fabric capable of blocking flow of high- viscosity fluid while excellent in permeability, thus useful for paper diapers, etc., by forming unevennesses on a fibrous web by specific means followed by heat fusing of the thermoplastic fiber contained in the web. CONSTITUTION:A fibrous web 2 containing thermoplastic fiber is brought between air-permeable conveyor belts 41 one or both of the surfaces of which have unevennesses, and during carrying said web 2 sandwiched between the conveyor belts, air is blown on the surface of said web 2 to force said web to follow the recesses of the conveyor belts 41 to effect formation of unevennesses on the web 2 followed by heating the web 2 to effect fusing of the thermoplastic fiber, thus obtaining the objective nonwoven fabric. |
