Abstract

A fabric is provided having a defined pattern of hydrophobic and hydrophilic regions that extend entirely through the thickness of the fabric so that the defined pattern is identical on the inner and outer surfaces of the fabric. The defined pattern is configured so that the hydrophilic regions are all in communication or interconnected so that moisture, such as perspiration, can wick not only from the inner to the outer surface of the fabric but also throughout the surface of the fabric and in several directions on the fabric so that the surface area of the wetted hydrophilic regions increases. The defined pattern may be further configured so that none of the hydrophobic regions are in communication.

First claim

What is claimed is:

1. An article of apparel comprising:
fabric defining a first surface and a second surface;
a hydrophilic network incorporated into the fabric, wherein the hydrophilic network extends from the first fabric surface to the second fabric surface, and wherein the hydrophilic network wicks moisture along the network; and
a plurality of hydrophobic regions disposed within the hydrophilic network, each of the of hydrophobic regions extending from the first fabric surface to the second fabric surface, wherein the plurality of hydrophobic regions divert moisture toward hydrophilic network.

2. The article of apparel according to claim 1 , wherein the hydrophilic network simultaneously wicks moisture from the first fabric surface to the second fabric surface and wicks moisture laterally along the fabric.

3. The article of apparel according to claim 1 , wherein the hydrophilic network is discontinuous along the fabric surfaces.

4. The article of apparel according to claim 1 , wherein the hydrophilic network comprises a plurality of leg members in fluid communication with each other.

5. The article of apparel according to claim 4 , wherein a hydrophobic region of the plurality of hydrophobic regions is surrounded by leg members of the hydrophilic network.

6. The article of apparel according to claim 4 , wherein a first region of the plurality of hydrophobic regions is separated from a second region of the plurality of hydrophobic regions by a leg member of the plurality of legs comprising the hydrophilic network.

7. The article of apparel according to claim 1 , wherein each of the plurality of hydrophobic regions define a polygon along each surface of the fabric.

8. The article of apparel according to claim 1 , wherein:
the fabric is hydrophobic; and
the hydrophilic network comprises a penetrant composition that renders fabric hydrophilic.

9. The article of apparel according to claim 1 , wherein:
the fabric is hydrophilic; and
the plurality of hydrophobic regions comprises a penetrant that renders the fabric hydrophobic.

10. The article of apparel according to claim 9 , wherein the hydrophobic penetrant is a composition containing silicone.

11. The article of apparel according to claim 1 , wherein the plurality of hydrophobic regions define a repeating geometric shape across each surface of the fabric.

12. The article of apparel according to claim 1 , wherein the first surface is an inner, user facing surface and the second surface is an outer surface.

13. A method of forming an article of apparel comprising:
obtaining fabric possessing a first affinity for moisture, the fabric having a first surface and a second surface opposite the first surface;
applying a penetrant to the first surface of the fabric, wherein the penetrant is applied in a discontinuous pattern; and
curing the penetrant to form a plurality of regions within the fabric, the plurality of regions possessing a second affinity for moisture different from the first affinity.

14. The method of claim 13 , wherein the penetrant is applied to the fabric such that the plurality of regions is a repeating pattern of regions.

15. The method of claim 13 , wherein the penetrant regions define a repeating pattern of geometric shapes along the fabric.

16. The method of claim 15 , wherein the geometric shapes are polygons.

17. The method of claim 13 , wherein the first affinity for moisture is greater than the second affinity for moisture.

18. The method of claim 13 , wherein the first affinity for moisture is less than the second affinity for moisture.

19. The method according to claim 13 , wherein the first affinity is selected from the group consisting of hydrophilic and hydrophobic.

20. An article of apparel comprising:
fabric defining a first surface and a second surface;
a hydrophilic network incorporated into the fabric including a plurality of interconnected members, wherein:
the hydrophilic network extends from the first fabric surface to the second fabric surface, and
the plurality of interconnected members wicks moisture along the network; and

a plurality of hydrophobic regions disposed within the hydrophilic network, each of the hydrophobic regions extending from the first fabric surface to the second fabric surface, wherein the plurality of hydrophobic regions divert moisture toward hydrophilic network,
wherein a hydrophobic region of the plurality of hydrophobic regions is surrounded by interconnected members.
