LIQUID-PERMEABLE NON-WOVEN FABRIC

WIPO Patent Application WO/2013/084977

A1

Provided is a liquid-permeable non-woven fabric which can be used suitably in an article for treating a body fluid. The liquid-permeable non-woven fabric (31) is formed with a thermoplastic synthetic fiber (30) and has, on the upper surface (21) thereof, raised parts (25) which are parallel to each other and extend in the direction of length (LD) of the liquid-permeable non-woven fabric (31). Each of the raised parts (25) has a top part (26) and skirt parts (27). The thermoplastic synthetic fiber (30) comprises a first fiber (41) and a second fiber (42). The first fiber (41) has a fineness ranging from 0.8 to 1.9 dtex and forms a thickness-direction (TD) upper part (43) including the upper surface (21) as observed in the thickness direction (TD) of the liquid-permeable non-woven fabric (31), and the second fiber (42) has a fineness ranging from 2.0 to 6.0 dtex and forms a thickness-direction (TD) lower part (44) including a lower surface (22) as observed in the thickness direction (TD) of the liquid-permeable non-woven fabric (31). The fineness of the first fiber (41) is smaller by at least 0.5 dtex than that of the second fiber (42).
