Abstract

A cleaning article includes a cleaning article sheet comprising a fabric substrate, wherein the fabric substrate includes pores therein, and wherein the fabric substrate has a background moisture percentage by weight, and liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at moisture percentage by weight that is 5 to 150 percentage points higher than the background moisture percentage. The nonwoven substrate can include pores formed between and/or within the fibers and can have a background moisture percentage by weight. The substrate can include a treatment to increase the dielectric constant from the dielectric constant of the substrate without the treatment. The moisture of the article can be configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article with only background moisture.

Claims (22)

1. A hard surface cleaning article comprising:

a cleaning article sheet comprising a fabric substrate including fibers, wherein the fabric substrate includes pores therein, and wherein the substrate includes a zwitterion grafted to the fibers to increase the dielectric constant of the substrate from the dielectric constant of the substrate without the zwitterion; and

a liquid disposed substantially and disconnectedly within the pores, the liquid consisting of liquid water, wherein the liquid water is at a moisture percentage by weight of 5 to 100 percent, wherein the cleaning article is configured to transfer liquid water to a surface, wherein the majority of water transferred to the surface is transferred by condensation.

2. The cleaning article of claim 1 , wherein the pores in the fabric substrate are formed between the fibers.

3. The cleaning article of claim 1 , wherein the pores in the fabric substrate are formed within the fibers.

4. The cleaning article of claim 1 , wherein the fabric substrate includes cellulosic material.

5. The cleaning article of claim 1 , wherein the fabric substrate includes polysaccharide material.

6. The cleaning article of claim 1 , wherein the article is configured to reabsorb a majority of the liquid water transferred to the surface.

7. The cleaning article of claim 1 , wherein the moisture of the article is configured to exhibit a dielectric constant of at least 50% and up to 700% higher than the dielectric constant of the same article when dry.

8. The cleaning article of claim 1 , wherein the moisture of the article is configured to exhibit a dielectric constant of at least 50% and up to 700% higher than the dielectric constant of the same article when dry, and wherein the article is configured to remove bacteria by establishing a dielectric gradient of ∈1(wipe) >∈2(microbial debris) >∈3(surface) during wiping.

9. The cleaning article of claim 8 , further comprising an alkoxysilane coupling agent.

10. The cleaning article of claim 1 , wherein the zwitterion is serine.

11. A hard surface cleaning article comprising:

a cleaning article sheet comprising a nonwoven substrate having fibers, wherein the nonwoven substrate includes pores formed between and/or within the fibers, and wherein the substrate includes a zwitterion grafted to the fibers to increase the dielectric constant from the dielectric constant of the substrate without the treatment; and

a liquid disposed substantially and disconnectedly within the pores, the liquid consisting of liquid water, wherein the liquid water is at a moisture percentage by weight of 5 to 100 percent, wherein the cleaning article is configured to transfer liquid water to a surface, wherein the majority of water transferred to the surface is transferred by condensation, wherein the moisture of the article is configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article when dry.

12. The cleaning article of claim 11 , wherein the zwitterion is serine.

13. The cleaning article of claim 11 , further comprising an alkoxysilane coupling agent.

14. A hard surface cleaning article comprising:

a cleaning article sheet comprising a nonwoven substrate having fibers, wherein the nonwoven substrate includes pores formed between and/or within the fibers;

a treatment on the substrate to increase the dielectric constant from the dielectric constant of the substrate without the treatment, wherein the treatment includes a zwitterion grafted to the fibers; and

liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at a moisture percentage by weight of 5 to 100 percent, wherein the cleaning article is configured to transfer liquid water to a surface, wherein the majority of water transferred to the surface is transferred by condensation, wherein the moisture of the article is configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article when dry, wherein the article is configured to remove bacteria by establishing a dielectric gradient of ∈1(wipe) >∈2(microbial debris) >∈3(surface) during wiping.

15. The cleaning article of claim 14 , wherein the zwitterion is serine.
