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.
Claims28
A wearable article for transferring perspiration away from an outer surface of a user comprising:
- a. a first layer that is permeable and is configured to contact the perspiration on the outer surface of the user while being worn;
- and
- b. a second layer including fibers that have been processed for alignment in a substantially parallel orientation relative to each other, the second layer configured to include a plurality of undulations having a crest and a trough defined from being vertically lapped and thereby resulting in a plurality of fibers oriented generally perpendicularly to the first layer and a plurality of interstitial spaces between and among the fibers for defining a fluid transport path for transporting the perspiration away from the first layer and through the second layer.
-31. (canceled)
A wearable article for transferring perspiration away from an outer surface of a user comprising:
- a. a first layer that is permeable and is configured to contact the perspiration on the outer surface of the user while being worn;
- b. a second layer including fibers that have been carded for alignment in a substantially parallel orientation relative to each other, the second layer configured to include a plurality of undulations having a crest and a trough defined from being vertically lapped and thereby resulting in a plurality of fibers oriented generally perpendicularly to the first layer and a plurality of interstitial spaces between and among the fibers for defining a fluid transport path for transporting the perspiration away from the first layer and through the second layer;
- wherein the interstitial spaces are defined by a frequency of the undulations;
- wherein the second layer comprises synthetic fibers and an elastomeric binder;
- and
- c. a third layer that is permeable and receives the perspiration from the second layer and is configured for wicking of the perspiration transported from the second layer and distributing the perspiration to promote evaporation;
- wherein a total thickness of the second layer is greater than a total thickness of the first layer and the third layer;
- wherein the first layer, the second layer, and the third layer each exhibit a permeability of about 600 L/m2/s or greater at 100 Pa;
- wherein the first layer, the third layer, or both comprises Lycra, polyester, polyethylene terephthalate, or a combination thereof;
- and
- wherein the article exhibits antimicrobial characteristics, antifungal characteristics, or both.
