Abstract

An article including one or more moisture wicking layers and one or more fibrous layers. The fibrous layers may have generally vertically oriented fibers, which may be oriented generally perpendicularly to a surface having or producing moisture. The article may be adapted to remove moisture form the surface having or producing moisture. The article may be breathable. The article may be quick drying. The article may provide cushioning. The article may be a wearable item.

First claim

What is claimed is:

1. A wearable and reusable article comprising:
a. one or more moisture wicking layers, wherein an inner moisture wicking layer is adapted to contact a surface having or producing moisture; and
b. a fibrous layer having a plurality of fibers including generally vertically oriented fibers as a result of a carding and lapping and/or air laying process,
wherein at least a portion of the generally vertically oriented fibers of the fibrous layer are positioned within the article to be oriented generally perpendicularly to the surface having or producing moisture;
wherein the fibrous layer includes fibers that are fused in space as a network so that the article has sufficient structure and body;
wherein an exterior surface of the article is an outer moisture wicking layer or the fibrous layer;
wherein the article is adapted to remove the moisture from the surface having or producing moisture via the inner moisture wicking layer transferring moisture to the fibrous layer; and
wherein each layer of the article is permeable to allow air flow through all of the layers of the article.

2. The article of claim 1 , wherein the surface having or producing moisture is skin of a body or a moist garment.

3. The article of claim 1 , wherein the fibrous layer is sandwiched between two moisture wicking layers.

4. The article of claim 1 , wherein the article is adapted to pull moisture from a user's skin, through the article, and onto the exterior surface of the article.

5. The article of claim 1 , wherein fibers of the fibrous layer have a non-circular cross-section.

6. The article of claim 1 , wherein the type and/or orientation of the fibers of the fibrous layer create a capillary effect to pull the moisture away from the surface.

7. The article of claim 1 , wherein the article exhibits structural resiliency to provide cushioning.

8. The article of claim 1 , wherein the fibrous layer is formed by a lapping process.

9. The article of claim 1 , wherein the article or one or more layers thereof is thermoformable to allow the article to be formed into a desired shape.

10. The article of claim 1 , wherein the article is washable.

11. The article of claim 1 , wherein the article exhibits antimicrobial characteristics, antifungal characteristics, mold or mildew resistance, or a combination thereof.

12. The article of claim 1 , wherein the fibrous layer includes bicomponent fibers.

13. The article of claim 1 , one or more of the layers are laminated together to form a laminated product prior to any additional shaping or molding steps.

14. The article of claim 1 , wherein the article is supplied as a roll or a sheet.

15. The article of claim 1 , wherein the fibrous layer includes fibers selected from polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), co-polyester/polyester (CoPET/PET) adhesive bi-component fibers, or a combination thereof.

16. The article of claim 15 , wherein the fibrous layer includes fibers including PET and bi-component fibers including a copolymer including PET.

17. The article of claim 8 , wherein the lapping process is a vertical lapping process.

18. The article of claim 1 , wherein the fibrous layer is formed by an air laying process.

19. The article of claim 1 , wherein the article or one or more layers thereof has a permeability of about 600 L/m 2 /s or greater at 100 Pa.

20. The article of claim 1 , wherein the article is selected from: a sweatband, a headband, a backpack, a pet harness, bike shorts, and pants.
