In a mop comprising a plurality of absorptive elements, a handle, and means joining said elements to said handle, the improvement wherein said absorptive elements comprise substantially flat strips of bonded nonwoven fabric, said strips ranging in width from about 5 to 60 mm, in length from about 15 to 60 cm and in thickness from about 0.5 to 3 mm. Binder may be printed onto the elements. The elements are flat and thus there is a greater area of contact with the surface being mopped. The elements may be joined into a round or elongate cross section mop by providing the elements with cuts through which a male member projects, the male member locking with a snap fit into a female member to which a mop handle is attached. Projections may be provided in the male and/or female members to immobilize the absorptive elements.
In a mop comprising a plurality of absorptive elements, a handle and means joining said elements to said handle, the improvement wherein said absorptive elements comprise a plurality of superposed flat layers of bonded non-woven fabric of about 1 to 2mm thickness and said non-woven fabric comprises a fibrous web and a binder, the fibrous web comprising at least about 50% by weight of hydrophilic fibers, the binder being present in about 25 to 100% by weight of the fibers, in about 50 to 400 grams per square meter, being printed onto said fabric in a pattern and being present in greater amount adjacent the surfaces than in the interior of said fabric, the layers being joined along a medial spine along which they are adapted to be commonly joined to the handle, the layers each being slit from said spine in both directions to the extremities thereof to form parallel flat strips ranging in width from about 15 to 40mm and in length from about 20 to 60 cm.
