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 without leaving a residue on a surface to be cleaned when a volatile additive is applied to the pad (28).

Claims

1. A cleaning system including a cleaning pad comprising:

a cleaning surface and a retention surface disposed on opposing sides of the cleaning pad;

a plurality of free-hanging fibers bound to at least one non-woven sheet on the cleaning surface of the cleaning pad; and

wherein the cleaning pad includes an additive impregnated throughout the cleaning surface and the retention surface having a vapor pressure of between 0.1 kPa to 10 kPa, and

wherein the cleaning pad is packaged in a sleeve to prevent evaporation of the additive.

2. The cleaning system of claim 1, wherein the additive has a vapor pressure of 1 kPa.

3. The cleaning system of claim 1, wherein the additive includes a solvent.

4. The cleaning system of claim 3, wherein the solvent is at least one of:

water, isopropanol, and propylene glycol n-butyl ether.

5. The cleaning system of claim 1, wherein the additive is at least one of:

an aqueous solution, a micellar solution, a microeniulsion, and a regular emulsion.

6. The cleaning system of claim 1, wherein the additive includes a surfactant that delivers amphiphillic properties to the cleaning pad.

7. The cleaning system of claim 1, wherein the additive does not leave a residue when the cleaning pad is moved across a surface to be cleaned.

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

9. The cleaning pad of claim 1, wherein the additive is combined with a fragrance.

10. The cleaning system of claim 1, further comprising an uninterrupted bonding line disposed along a longitudinal axis of the cleaning pad bonding at least a first non-woven sheet to a second non-woven sheet and plurality of spot bonds disposed on opposing sides of the continuous bonding line, the plurality of spot bonds:

a) bonding a portion of the plurality of free-hanging fibers to a first side of a first non-woven sheet, and b) bonding a second non-woven sheet to a second side of the first non-woven sheet.

11. A cleaning pad for dusting comprising a fiber mat impregnated throughout the cleaning pad with a volatile additive that has a vapor pressure of between 0.01 kPa to 10 kPa, the fiber mat comprising a retaining sheet bonded along a bonding line and spot bonding regions to a plurality of individual loose tow fibers on a first surface of the retaining sheet and to a base sheet on a second surface of the retaining sheet, and

wherein the bonding line and spot bonding regions cooperate to form at least one sleeve between the retaining sheet and the base sheet.

12. The cleaning pad of claim 11, wherein the cleaning pad is stored in a container to prevent evaporation of the additive prior to use.

13. The cleaning pad of claim 11, wherein the volatile additive includes a surfactant that delivers amphiphillic properties to the fiber mat of the cleaning pad.

14. The cleaning pad of claim 11, wherein the volatile additive is sprayed onto the pad from a bottle.

15. The cleaning pad of claim 11, wherein the volatile additive is combined with a fragrance. and does not leave a residue when the cleaning pad is moved across a surface to be cleaned.

16. The cleaning pad of claim 11,wherein the volatile liquid additive increases a percentage dust pickup by weight by 25 percent to 68 percent.

17. The cleaning system of claim 16, wherein the cleaning pad is 15 percent to 85 percent saturated with the volatile liquid additive.

18. The cleaning system of claim 17, wherein the cleaning pad is 25 percent saturated with the volatile liquid additive.

19. The cleaning pad of claim 11, wherein the individual loose tow fibers are bound intermittently to a first surface of a first non-woven sheet by the discontinuous bonding line, and wherein the discontinuous bonding line joins a second non-woven sheet to a second surface of the first non-woven sheet.
