Abstract

A disposable cleaning wipe that can used by hand or by attachment to a sweeper is provided wherein the cleaning wipe has tacky pick-up material concentrated at its working surfaces as opposed to within its intermediate region.

Claims (21)

1. A disposable cleaning wipe comprising:

(a) a single-layer fibrous material having a first working surface section and a second working surface section at opposing exterior sides of the single-layer fibrous material wherein each of the opposing working surface sections has an exposed surface and at least one of the opposing working surface sections comprises a tacky material designed to assist in picking up dirt and dust; and

(b) an intermediate region between the two opposing working surface sections wherein the intermediate region comprises the tacky material;

wherein the concentration of tacky material at the at least one of the exposed surfaces is greater than the concentration of tacky material within the intermediate region.

2. The disposable cleaning wipe according to claim 1 , wherein the exposed surface of the first working surface section and the exposed surface of the second working surface section comprise the tacky material and the concentration of tacky material at both exposed surfaces of the working surface sections is greater than the concentration of tacky material within the intermediate region.

3. The disposable cleaning wipe according to claim 2 , wherein the concentration of tacky material at the exposed surfaces of the working surface sections is approximately the same.

4. The disposable cleaning wipe according to claim 1 , wherein the wipe is shaped to conform to the surface of a sweeper mop head and to be attached thereto.

5. A sweeper mop comprising a handle and a sweeper mop head wherein the disposable cleaning wipe according to claim 1 is attached to the sweeper mop head.

6. The disposable cleaning wipe according to claim 1 , wherein the wipe comprises polyester staple fiber having a fineness of 7 to 35 dtex.

7. The disposable cleaning wipe according to claim 1 , wherein the wipe has a basis weight of 100 to 110 grams per square meter.

8. The disposable cleaning wipe according to claim 1 , wherein the tacky material is a pressure sensitive adhesive.

9. The disposable cleaning wipe according to claim 8 , wherein the pressure sensitive adhesive is chosen from the group consisting of a hot-melt pressure sensitive adhesive, a water-based pressure sensitive adhesive, and an oil-based pressure sensitive adhesive.

10. The disposable cleaning wipe according to claim 1 , wherein the wipe comprises a polyester wadding.

11. The disposable cleaning wipe according to claim 1 , wherein the wipe comprises a polyester non-woven web.

12. A method of manufacturing a disposable cleaning wipe comprising the steps of:

(a) forming a non-woven or woven single-layer fibrous material having a first working surface section and a second working surface section at opposing exterior sides of the single-layer fibrous material wherein each of the opposing working surface sections has an exposed surface and wherein the single-layer fibrous material has an intermediate region between the two opposing working surface sections;

(b) spraying a tacky material on at least one of the exposed surfaces of one of the working surface sections without compressing the non-woven or woven single-layer fibrous material so that the at least one of the working surface sections and the intermediate region comprises a tacky material and wherein the concentration of tacky material at the at least one of the exposed surfaces is greater than the concentration of tacky material within the intermediate region;

(c) drying the material to which the tacky material has been sprayed; and

(d) cutting the material into multiple disposable cleaning wipes.

13. The method of manufacturing according to claim 12 , wherein tacky material is sprayed onto both of the exposed surfaces of the working surface sections.

14. The method of manufacturing according to claim 12 , wherein the material is cut into multiple disposable cleaning wipes prior to drying the material.
