    摘要: A cleaning pad for a robot cleaner includes a back piece, an absorbent sheet, and a water permeable web. The water permeable web has a web body which is of such a dimension as to form a downward draping unit to shield the absorbent sheet. The downward draping unit is embossed toward the back piece and along at least one line oriented in a lengthwise direction to form successive downward draping members each defining a height between a lowermost area thereof and a lower major surface of the back piece. The heights of the successive downward draping members are incrementally decreased from a rearmost one of the successive downward draping members to a frontmost one of the successive downward draping members.

    摘要: A non-woven fabric includes a filament fiber web and a composite fiber web that is entangled with the filament fiber web and that includes composite staple fibers and cellulose fibers. The composite staple fibers and the cellulose fibers are fusion-bonded together. A method of fabricating a non-woven fabric includes: (a) air laying and thermally treating composite staple fibers and cellulose fibers so as to form a composite fiber web, the composite staple fibers and the cellulose fibers in the composite fiber web being fusion-bonded together, and (b) disposing the composite fiber web between two filament fiber webs followed by subjecting to water-jet treatment such that the composite fiber web and the filament fiber webs are entangled with each other.
