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.

First claim

What is claimed is:

1. A hard surface cleaning article comprising sheet further 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 ΔG′ 25 measured between 0.1 and 100 rad/s of more than 100%;
wherein said adhesive is an oil gel and comprises from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C 8 -C 22 ), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C 5 resins, C 5 -C 9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers, wherein at least one of the fabric layers has holes.

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 comprises from 0.5% to 49% by weight of a polymer or mixture of polymers.

5. A hard surface cleaning article according to claim 1 , wherein said sheet comprises a polymeric film.

6. A hard surface cleaning article according to claim 1 , wherein said sheet comprises a nonwoven.

7. A hard surface cleaning article according to claim 6 wherein said sheet comprises peaks and valleys.

8. A hard surface cleaning article comprising a sheet and further comprising an adhesive disposed on said sheet, said adhesive having:
an oil gel and comprising from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C 8 -C 22 ), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C 5 resins, C 5 -C 9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers.

9. A hard surface cleaning article according to claim 8 wherein said sheet comprises a nonwoven.

10. A hard surface cleaning article according to claim 8 wherein said sheet comprises a nonwoven having peaks and valleys and said adhesive is disposed only in said valleys.

11. A hard surface cleaning article according to claim 8 wherein said adhesive has a modulus G′ 25 measured at 25° C. and 0.1 rad/s below 15000 Pa.

12. A hard surface cleaning article according to claim 8 wherein sais adhesive has an elastic modulus percent increase ΔG′ 25 measured between 0.1 and 100 rad/s of more than 100%.

13. A hard surface cleaning article comprising a sheet and further comprising an adhesive disposed on said sheet, said adhesive having:
an oil gel and comprising from about 75% to 95% by weight of a plasticizer selected from the group consisting of vegetable oils, epoxidized and polymerized derivatives of vegetable oils, monocarboxylic fatty acids (C 8 -C 22 ), and their derivatives and from about 1% to about 48.5% by weight of a tackifier selected from the group consisting of hydrocarbon resins; aliphatic resins; terpene and terpene-phenolic resins; aromatic and aromatically modified resins; synthetic C 5 resins, C 5 -C 9 resins and mixtures thereof having a softening point of 160° C. or less, wherein said adhesive is present in a recessed area of said article and said adhesive does not directly contact the surface to be cleaned, wherein the sheet comprises at least three layers comprising a layer of said adhesive sandwiched between fabric layers,
wherein said sheet comprises at least one of a nonwoven and a polymeric film.

14. A hard surface cleaning article according to claim 13 wherein said adhesive is a hot melt adhesive.

15. A hard surface cleaning article according to claim 13 , wherein said adhesive comprises from 0.5% to 49% by weight of a polymer or mixture of polymers.

16. A hard surface cleaning article according to claim 13 further comprising a cleaning lotion.

17. A hard surface cleaning article according to claim 13 further comprising a wax.
