Abstract

The present invention relates to a cleaning implement comprising hybrid foam and to a method of cleaning a hard surface with said cleaning implement.

Claims (11)

1. A cleaning implement having a volume from 1 cm 3 to 10,000 cm 3 and comprises a layer of a hybrid foam wherein said hybrid foam comprises an open cell melamine formaldehyde resin of foamable reactive resins, and a substrate material, wherein said substrate material comprises a nonwoven fabric, wherein said foamable reactive resin is applied to said substrate material or said substrate material is saturated with said foamable reactive resin

and wherein said cleaning implement additionally comprises a second layer of material, wherein said second layer of material is selected from the group consisting of polyurethane foams; polypropylene foams; and combinations thereof

wherein said layer of hybrid foam and said second layer of material are joined by a permanent attachment or a temporary attachment, wherein the substrate material is selected from the group consisting of polyurethane resins, polyester resins, epoxides and mixtures thereof and the weight ratio of substrate material to the foamable resin is from 10% to 20%, by weight.

2. A cleaning implement according to claim 1 , wherein said cleaning implement has a thickness of at least 15 mm.

3. A cleaning implement according to claim 2 , having a shape selected from the group consisting of: cube shape, rectangular shape, pyramid shape, cylindrical shape, cone shape, pencil eraser shape, cuboid shape, and tetrahedron shape.

4. A cleaning implement according to claim 1 , wherein said layers of said hybrid foam and said layer of said second material are joined by an attachment means providing a permanent attachment selected from the group consisting of foam flame laminating the layers together; use of a permanent adhesive; sewing the layers together; needle-punching the layers together; and combinations thereof.

5. A cleaning implement according to claim 1 , wherein the thickness of said hybrid foam layer is from about 5 mm to about 100 mm.

6. A cleaning implement according to claim 1 , wherein said hybrid foam comprises at least one additive selected from the group consisting of biocides, solids, surfactants, colorants, lubricants, cross-linkers, fragrances, plasticizers, odor scavengers, microcapsules and combinations thereof.

7. A cleaning implement according to claim 6 , wherein said solids are abrasive materials, filler materials, or combinations thereof.

8. A method of cleaning a hard surface with a cleaning implement ( 1 ) according to claim 1 .

9. A cleaning implement according to claim 1 wherein said layer of hybrid foam has less than 4 pores per cm and a pore size of 50 to 300 micrometers.
