Abstract

An article of apparel is disclosed that is at least partially formed from a material element having a substrate and a plurality of projections. The substrate has a first surface and an opposite second surface. The projections extend from the first surface of the substrate, and the projections each have terminal ends located opposite the substrate. The material element has a first permeability when the first surface has a convex configuration, and the material element has a second permeability when the first surface has a concave configuration, the first permeability being greater than the second permeability. The apparel may be reversible such that either the first surface or the second surface of the substrate faces outward.

First claim

The invention claimed is:

1. An article of apparel, comprising:
a first material element having a first substrate with a first surface and a second surface opposite the first surface, the first material element having a first plurality of elongated projections extending from the first surface, wherein the first substrate and the first plurality of elongated projections are a unitary knitted construction, and wherein each elongated projection of the first plurality of elongated projections includes a first terminal end and a first plurality of connecting fibers extending between the first terminal end and the first substrate; and
a second material element having a second substrate with a third surface and a fourth surface opposite the third surface, wherein the third surface has a second plurality of projections extending from the third surface, wherein each projection of the second plurality of projections includes a second terminal end and a second plurality of connecting fibers extending between the second terminal end and the third surface,
wherein the first material element comprises an arm region of the article of apparel and the second material element comprises a torso region of the article of apparel,
wherein the second material element is positioned adjacent the first material element and joined to the first material element to define a seam between edges of the first material element and the second material element, and
wherein the article of apparel is reversibly convertible between a first configuration and a second configuration, the first surface facing outward from the article of apparel in the first configuration, and the second surface facing outward from the article of apparel in the second configuration.

2. The article of apparel recited in claim 1 , wherein the second material element is a textile.

3. The article of apparel recited in claim 2 , wherein the first material element is a spacer knit material formed through a double needle bar raschel knitting process.

4. The article of apparel recited in claim 1 , wherein, in the first configuration, spaces are provided between adjacent individual projections.

5. The article of apparel recited in claim 1 , wherein, in the first configuration, spaces are provided between adjacent individual projections and in the second configuration, adjacent individual projections abut or contact one another.

6. The article of apparel recited in claim 1 , wherein, in the second configuration, adjacent individual projections abut or contact one another.

7. The article of apparel recited in claim 1 , wherein the seam between edges of the first material element and the second material element is structured to exhibit a finished structure in both the first configuration and the second configuration.

8. The article of apparel recited in claim 1 , wherein the first material element has a greater air permeability in the first configuration than in the second configuration.

9. An article of apparel, comprising:
a first material element having a first substrate with a first surface and a second surface opposite the first surface, wherein the first material element has a first plurality of projections extending from the first surface, wherein the first substrate and the first plurality of projections are a unitary knitted construction and wherein each projection of the first plurality of projections includes a first terminal end and a first plurality of connecting fibers extending between the first terminal end and the first substrate; and
a second material element having a second substrate with a third surface and a fourth surface opposite the third surface, wherein the third surface has a second plurality of projections extending from the third surface,
wherein the second material element is positioned adjacent the first material element and joined to the first material element to define a seam between edges of the first material element and the second material element, wherein the first material element comprises an arm region of the article of apparel and the second material element comprises a torso region of the article of apparel,
wherein the first plurality of projections has a first spacing between adjacent projections and the second plurality of projections has a second spacing between adjacent projections, wherein the second spacing is greater than the first spacing, and
wherein the article of apparel is reversibly convertible between a first configuration and a second configuration, the first surface facing outward from the article of apparel in the first configuration, and the second surface facing outward from the article of apparel in the second configuration.

10. The article of apparel recited in claim 9 , wherein the seam between edges of the first material element and the second material element is structured to exhibit a finished structure in both the first configuration and the second configuration.

11. The article of apparel recited in claim 9 , wherein the third surface faces outward from the article of apparel in the first configuration and the fourth surface faces outward from the article of apparel in the second configuration.

12. The article of apparel recited in claim 9 , wherein each projection of the second plurality of projections includes a second terminal end and a second plurality of connecting fibers extending between the second terminal end and the third surface.

13. The article of apparel recited in claim 12 , wherein each projection of the first plurality of projections has a first height defined by a first distance from the first terminal end and the first substrate and each projection of the second plurality of projections has a second height defined by a second distance from the second terminal end and the third surface, wherein the first height is less than the second height.

14. The article of apparel recited in claim 9 , wherein the first plurality of projections and the second plurality of projections have an elongated shape.

15. The article of apparel recited in claim 9 , wherein the first material element has a greater air permeability in the first configuration than in the second configuration.

16. An article of apparel, comprising:
a first material element having a first substrate with a first surface and a second surface opposite the first surface, the first material element having a first plurality of projections extending from the first surface, wherein the first substrate and the first plurality of projections are a unitary knitted construction, wherein each projection of the first plurality of projections includes a first terminal end and a first plurality of connecting fibers extending between the first terminal end and the first substrate, and wherein each projection of the first plurality of projections has a first height defined by a first distance from the first terminal end and the first substrate, and
a second material element having a second substrate with a third surface and a fourth surface opposite the third surface, the third surface having a second plurality of projections extending from the third surface, wherein each projection of the second plurality of projections includes a second terminal end and a second plurality of connecting fibers extending between the second terminal end and the third surface, and wherein each projection of the second plurality of projections has a second height defined by a second distance from the second terminal end and the third surface, wherein the first height is less than the second height,
wherein the second material element is positioned adjacent the first ma
