Claim 5:
6. A cleaning pad of stitch-bonded construction adapted for attachment to a user manipulated mop head, the cleaning pad comprising:
at least one fluid absorbing composite substrate layer comprising polypropylene in layered relation with fluid-retaining nonwoven;
at least a first plurality of yarns of multifilament construction extending in patterned stitched relation through the fluid absorbing layer, the first plurality of yarns comprising an effective percentage of microdenier filaments having a linear density of less than 1 denier per filament, wherein the first plurality of yarns forms a first plurality of loops projecting outwardly away from a first side of the fluid absorbing layer, the first plurality of yarns also forming a first plurality of flat stitches in overlying relation to a second side of the fluid absorbing layer facing away from the first side, and wherein the first plurality of loops defines an operative particle retention surface for the cleaning pad and the first plurality of flat stitches defines an attachment surface for hooking engagement to the mop head; and
at least a second plurality of yarns extending in patterned stitched relation through the fluid absorbing layer, the second plurality of yarns being made up predominantly of filaments having a linear density at least 3 times greater than the microdenier filaments in the first plurality of yarns, wherein the second plurality of yarns forms a second plurality of loops projecting outwardly away from the first side of the fluid absorbing layer, the second plurality of yarns also forming a second plurality of flat stitches in overlying relation to the second side of the fluid absorbing layer facing away from the first side.
