Abstract

Absorbent, multilayer cleaning fabrics are provided which have (i) a porous, abrasion resistant liquid pervious top layer, (ii) a liquid impervious bottom layer, and (iii) an absorbent mat sealed between the top and bottom layers. The top and/or bottom layers form highly flexible tabs that extend beyond the absorbent mat and allow the cleaning fabric to be easily attached and removed from a cleaning tool having fasteners. The multilayer cleaning fabrics are well suited for wiping wet surfaces and/or cleaning surfaces with soap and water or other liquid cleaners.

Claims

1. A pre-moistened multilayer cleaning fabric comprising:

a liquid transfer layer;

a liquid barrier layer; and

an absorbent material positioned between said liquid transfer layer and said liquid barrier layer, said absorbent material comprising a mixture of thermoplastic polymer fibers and pulp, and said absorbent material further comrising a liquid.

2. The pre-moistened multilayer cleaning fabric of claim 1 wherein said absortent material comprises a stabilized matrix of thermoplastic polymer fibers and pulp.

3. The pre-moistened multilayer cleaning fabric of claim 2 wherein said absorbent material comprises a stabilized matrix of meltblown fibers and pulp.

4. The pre-moistened multilayer cleaning fabric of claim 3 wherein said meltblown fibers comprise polypropylene fibers.

5. The pre-moistened multilayer cleaning fabric of claim 1 wherein said liquid transfer layer comprises a nonwoven web of spunbond fibers.

6. The pre-moistened multilayer cleaning fabric of claim 5 wherein said liquid transfer layer has an abrasion resistance of at least 500 cycles.

7. The pre-moistened multilayer cleaning fabric of claim 5 wherein said liquid transfer layer comprises a nonwoven web of spunbond fibers having a cross-sectional shape selected from the group consisting of multilobal, crescent, and wedge shaped fibers.

8. The pre-moistened multilayer cleaning fabric of claim 5 where said liquid transfer layer comprises a nonwoven web of split spunbond fibers.

9. The pre-moistened multilayer cleaning fabric of claim 5 wherein said liquid transfer layer contains a plurality of apertures therein.

10. The pre-moistened multilayer cleaning fabric of claim 1 wherein said absorbent material has an absorbency of at least about 15 g/g.

11. The pre-moistened multilayer cleaning fabric of claim 1 wherein said liquid transfer layer comprises an apertured nonwoven web and has an abrasion resistance of at least 500 cycles.

12. A cleaning implement comprising:

a handle

ahead; and

the cleaning sheet of claim 1, wherein said liquid barrier layer faces said head and further wherein said cleaning fabric is releasably engaged with said head.
