Abstract
A sanitary article is disclosed. The sanitary article comprises a disposable, macroscopically three-dimensional sheet. The sheet has a first surface and a second surface. One of the surfaces comprises a macroscopic three-dimensional texture. The macroscopic three-dimensional texture comprises peaks and valleys such that the textured surface may have an Average Peak to Peak Distance in the range of about 3 mm to about 16 mm, an Average Height Differential in the range of 1 mm to about 3 mm, and a Surface Topography Index in the range of about 0.1 to about 5. The sanitary article may comprise a surfactant on the sheet.
Claims27
An article of manufacture comprising:
- a disposable, macroscopically three-dimensional sheet comprising a first nonwoven substrate and a second nonwoven substrate, wherein the first and second nonwoven substrates are hydroentangled together;
- wherein the sheet has a first surface and a second surface;
- wherein one of the surfaces comprises a macroscopic three-dimensional texture;
- wherein the macroscopic three-dimensional texture comprises peaks and valleys such that the one textured surface has:
- an Average Peak to Peak Distance in the range of 4 mm to about 12 mm;
- a first peak and a first valley having a first height therebetween;
- a second peak and a second valley having a second, different height therebetween;
- an Average Height Differential in the range of about 1 mm to about 3 mm;
- and
- a Surface Topography Index in the range of about 0.01 to about 5;
- wherein the sheet has a CD Elongation value at 500 grams of at least 15%;
- wherein one of the first and second nonwoven substrates comprises polypropylene;
- and
- wherein the other of the first and second nonwoven substrates comprises polyester.
