Abstract: A cleaning sheet (1) includes a hydrophilic fiber aggregate (11) and a hydrophobic fiber aggregate (12) disposed on both sides of the hydrophilic fiber aggregate (11). The hydrophobic fiber aggregate (12) has its constituent fibers (14) entangled with one another, entering the hydrophilic fiber aggregate (11), and entangled with fibers (13) of the hydrophilic fiber aggregate (11). The cleaning sheet (1) is three-dimensionally textured with a plurality of protrusions (2) and a plurality of depressions (3) on both sides thereof. The protrusions (2) on one side correspond to the depressions (3) on the other side, and the depressions (3) on one side correspond to the protrusions (2) on the other side. The cleaning sheet (1) has linear bonds (15) where the hydrophilic fiber aggregate (11) and the hydrophobic fiber aggregate (12) are bonded to each other.

Abstract: A cleaning article 10 having a flat tubular pocket 15 and attachable to a holder by inserting the holder into the pocket 15. The pocket 15 is formed by joining pocket-forming sheets 13 facing each other. At least one fiber layer formed of a fiber bundle, accordingly two fiber layers 11A and 11B are provided on each of the upper and lower sides of the pocket 15 of the pocket-forming sheets 13. Each of the first fiber layers 11A closest to the pocket-forming sheets 13 is joined to the respective pocket-forming sheet 13 by a continuous central linear seal 16A continuously extending in the longitudinal direction in a laterally middle portion and a discontinuous side seal 16B discontinuously extending in the longitudinal direction at a position laterally spaced away in at least one of the lateral directions from the central continuous linear seal 16A.

Abstract: A cleaning article 10 having a pair of flat tubular pockets 15 and attachable to a holder 20 by inserting the holder 20 into the pockets 15. The cleaning article 10 includes fiber layers 11a and 11b and fiber layers 11c and 11d each formed of a fiber bundle on the upper and lower side, respectively, of the pockets 15. The pockets 15 are formed by joining two oblong sheets 13a and 13b interposed between the upper and lower fiber layers 11b and 11c by making joining zones extending in the longitudinal direction of the sheets 13a and 13b to define both longer sides of each pocket 15. The pockets 15 each have an unjoined region in an end portion on the side of their inlets 151.
