Abstract

The present invention relates to articles for cleaning hard surfaces and in particular to remove large particles and hairs from large surfaces. The articles comprise an adhesive having specific Theological properties that provide increased efficacy in capturing and trapping large particles and hairs.

Claims

1. A hard surface cleaning article comprising an adhesive having:

a. An elastic modulus G′

₂₅ measured at 25°

C. and 0.1 rad/s below 15000 Pa,

and

b. An elastic modulus percent increase Δ

G′

₂₅ measured between 0.1 and 100 rad/s of more than 100%.

2. A hard surface cleaning article according to claim 1, wherein said adhesive has a crossover frequency of less than 1000 rad/s.

3. A hard surface cleaning article according to claim 1, wherein said adhesive is a hot melt adhesive.

4. A hard surface cleaning article according to claim 1, wherein said adhesive is an oilgel.

5. A hard surface cleaning article according to claim 1, wherein said adhesive comprises from 0.5% to 49% by weight of a polymer or mixture of polymers, and from 51% to 99.5% by weight of a plasticizer or mixture of plasticizers.

6. A hard surface cleaning article according to claim 1, wherein said article is a sheet, a wipe or a pad.

7. A hard surface cleaning article according to claim 6, wherein said adhesive is applied to one side of said sheet, wipe or pad and wherein a layer having an open structure is applied to said side of said sheet, wipe or pad having the adhesive applied thereto.

8. A method of removing particles and or hairs from an hard surface comprising passing onto said surface an article comprising an adhesive having:

a. An elastic modulus G′

₂₅ measured at 25°

C. and 0.1 rad/s below 15000 Pa,

and

b. An elastic modulus percent increase Δ

G′

₂₅ measured between 0.1 and 100 rad/s of more than 100%.

9. The use of an adhesive having:

a. An elastic modulus G′

₂₅ measured at 25°

C. and 0.1 rad/s below 15000 Pa,

and

b. An elastic modulus percent increase Δ

G′

₂₅ measured between 0.1 and 100 rad/s of more than 100%,

to remove particles and/or hairs from a hard surface.
