Abstract

A cleaning pad ( 28 ) is disclosed. The cleaning pad ( 28 ) includes a base sheet ( 202 ) bonded to a fiber mat ( 203 ) and exhibits improved debris retention when an additive that exhibits amphiphillic properties is applied to the pad ( 28 ). The additive may be added to the pad ( 28 ) during manufacture or selectively applied by a user.

Claims (23)

1. A cleaning system having a cleaning pad comprising:

at least one-nonwoven sheet; and

a plurality of fibers discontinuously bound to a surface of the nonwoven sheet, the plurality of fibers orientated to conceal the surface of the nonwoven sheet, wherein the cleaning pad is treated with an additive applied to the cleaning pad by a user, the additive having amphiphillic properties; and

a fluid source operatively coupled to a cleaning tool and removably located within a handle portion of the cleaning tool, wherein the fluid source selectively applies the additive to at least one of: a surface to be cleaned and the fibers of the cleaning pad.

2. The cleaning system of claim 1 , wherein the additive comprises a solvent containing at least one of: an aldehyde, an alcohol, a surfactant, a functionalized silicone, a non-functionalized silicone, a carboxylic acid, monoethanol amine and an amine.

3. The cleaning system of claim 1 , wherein the additive is an amphoteric surfactant.

4. The cleaning system of claim 3 , wherein the surfactant is disodium cocoamphodiacetate.

5. The cleaning pad of claim 3 , wherein the surfactant is disodium decyl(sulphonatophenoxy)benzenesulfonate.

6. The cleaning system of claim 1 , wherein the additive is at least one of: an anionic surfactant; a cationic surfactant; and a zwitterionic surfactant.

7. The cleaning system of claim 1 , wherein the additive is a solvent with hydrogen bonding character.

8. The cleaning system of claim 1 , wherein the additive is an organic molecule with an ionizable polar head group.

9. The cleaning system of claim 1 , wherein the additive further comprises a mineral oil.

10. The cleaning system of claim 1 , wherein the additive further comprises a wax.

11. The cleaning system of claim 1 , wherein the additive is impregnated directly onto the cleaning pad during manufacture of the cleaning pad.

12. The cleaning system of claim 1 wherein the additive increases a percentage dust pick up by weight by 25 percent to 68 percent.

13. The additive of claim 12 having a liquid surface tension between 45 mN/m and 72 mN/m.

14. The cleaning system of claim 12 , wherein the liquid additive is applied to the cleaning pad at a liquid level of between 0.1 g/sq.ft. and 0.3 g/sq.ft.

15. The cleaning system of claim 1 , wherein the additive further comprises a non-hydrocarbon based amphiphile.

16. The cleaning system of claim 1 , further comprising a second nonwoven sheet bound to a side of the at least one nonwoven sheet opposite the plurality of fibers.

17. A cleaning system suitable for use in dusting comprising:

a cleaning pad having a plurality of fibers and at least one nonwoven sheet, the plurality of fibers arranged to conceal one surface of the nonwoven sheet, said fibers bound to the surface of the nonwoven sheet along a central bonding line; and

a cleaning tool supporting the cleaning pad and a fluid source removably located within a handle portion of the cleaning tool, the fluid source comprising a fluid having amphiphillic properties.

18. The system of claim 17 wherein the fluid source selectively applies a cleaning fluid to at least one of: a surface to be cleaned and directly to the fibers of the cleaning pad.
