Abstract:
A wiping sheet comprising:exterior sheets comprising an absorbent fiber and a thermoplastic hydrophobic fiber, each of the exterior sheets having a basis weight of 25 to 55 g/m.sup.2, being a spunlace non-woven fabric and having most of the fibers oriented in a direction; andan absorbent core interposed between said exterior sheets, said absorbent core comprising an absorbent fiber and a thermoplastic hydrophobic fiber and having a basis weight of 25 to 60 g/m.sup.2 and being a non-woven fabric produced by thermally bonding together the thermoplastic hydrophobic fiber so that the absorbent core has a greater bending resistance than the exterior sheets, said absorbent core and said exterior sheets being bonded together on bonding lines formed across the direction in which most of the fibers are oriented in the exterior sheets, whereby the wiping sheets having a bending resistance of 70 mm or more in a dry state and a bending resistance of 60 mm or more in such a state that the wiping sheet contains water, whereby the weight of the water is four-fold to the weight of the wiping sheet in the dry state, as measured by the cantilever method according to JIS/L1096 using a test piece of the wiping sheet with a width dimension of 25 mn.
