Abstract

A method of evaluating the stickiness of an outer surface of an absorbent article comprises the steps of: (i) providing an absorbent article on a stationary horizontal surface, the absorbent article having an outer surface facing away from the stationary horizontal surface, (ii) affixing an adhesive substrate to the outer surface of the absorbent article, (iii) grasping an end portion of the adhesive substrate, and (iv) lifting the end portion of the adhesive substrate in a direction away from the stationary horizontal surface.

Claims

1. A method for evaluating the stickiness of an outer surface of an absorbent article, said method comprising the steps of:

providing said absorbent article on a stationary horizontal surface, said outer surface of said absorbent article facing away from said stationary horizontal surface,

affixing an adhesive substrate to said outer surface of said absorbent article,

grasping an end portion of said adhesive substrate, and

lifting said end portion of said adhesive substrate in a direction away from said stationary horizontal surface.

2. The method of claim 1, wherein said adhesive substrate comprises a substrate and an adhesive material disposed on said substrate.

3. The method of claim 2, wherein said substrate of said adhesive substrate is selected from the group consisting of film, paper, cloth, mesh, foil, and combinations thereof.

4. The method of any one of claims 2 or 3, wherein said adhesive material of said adhesive substrate is selected from the group consisting of pressure sensitive adhesive, acrylic emulsion, acrylic solvent, hot melt rubber, rubber solvent, and mixtures thereof.

5. The method of any one of the preceding claims, wherein said adhesive substrate is a pressure sensitive tape.

6. The method of any one of the preceding claims, wherein said outer surface is a top outer surface of said absorbent article.

7. The method of any one of the preceding claims, wherein said outer surface of said absorbent article comprises a topsheet material.

8. The method of claim 7, wherein said topsheet material is comprised of a material selected from the group consisting of a thermoplastic film and a nonwoven material.

9. The method of any one of claims 7 or 8, wherein said topsheet is a thermoplastic film and comprises a plurality of discrete extended elements.

10. The method of claim 9, wherein said discrete extended elements are generally columnar and have an aspect ratio of at least about 0.2.

11. The method of any one of the preceding claims, wherein said absorbent article is a first absorbent article and said adhesive substrate is a first adhesive tape, wherein said method further comprises the steps of:

providing a second absorbent article on said stationary horizontal surface, said second absorbent article having an outer surface, wherein said outer surface of said second absorbent article is different from said outer surface of said first absorbent article,

affixing a second adhesive tape to said outer surface of said absorbent article, wherein said second adhesive tape has the same composition as said first adhesive tape,

grasping an end portion of said second adhesive tape, and

lifting said end portion of said second adhesive tape in a direction away from said stationary horizontal surface.

12. The method of claim 11, wherein said method further comprises the step of comparing the degree to which the first adhesive tape detaches from said outer surface of said first absorbent article to the degree to which the second adhesive substrate detaches from said outer surface of said second absorbent article.

13. The method of any one of claims 11 or 12, wherein said end portion of said second adhesive tape is lifted at the same time as the end portion of said first adhesive tape is lifted.
