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. A garment comprising:
a fabric having an inner surface and an outer surface and having a repeating pattern of hydrophobic regions and hydrophilic regions,
wherein the hydrophilic regions and hydrophobic regions extend from the inner surface to the outer surface of the fabric, and
further wherein all of the hydrophilic regions are interconnected and in fluid communication throughout the fabric and all of the hydrophobic regions are isolated from each other throughout the fabric.

2. The garment of claim 1 , wherein the hydrophilic regions occupy greater than 50% of a total surface area of the inner and outer surfaces of the fabric.

3. The garment of claim 2 , wherein the hydrophilic regions occupy about 60% of said total surface area.

4. The garment of claim 1 , wherein the hydrophobic regions are substantially similar in shape and the hydrophilic regions surround the shape of each hydrophobic region at a substantially uniform width.

5. The garment of claim 4 , wherein:
the shape of each hydrophobic region is an equilateral triangle with sides having a length of about 6 mm; and
said substantially uniform width of the hydrophilic regions is about 2 mm.

6. The garment of claim 1 , wherein:
said fabric comprises a hydrophilic material capable of wicking water from the inner surface to the outer surface; and
said hydrophobic regions of said fabric comprise a water-repellant composition.

7. The garment of claim 1 , wherein:
said fabric is formed of a hydrophobic material that is generally impermeable to water from the inner surface to the outer surface; and
said hydrophilic regions of said fabric are treated with a hydrophilic composition.

8. The garment of claim 1 , wherein a composition that is either hydrophilic or hydrophobic is applied to the fabric in said repeating pattern to form said hydrophilic and hydrophobic regions.

9. The garment of claim 8 , wherein said composition is applied by a printing operation on one of said inner and outer surface sufficient so that said composition penetrates to the other of said inner and outer surface.

10. A fabric comprising:
an inner surface and an outer surface; and
a repeating pattern of hydrophobic regions and hydrophilic regions extending from the inner surface to the outer surface of the fabric,
wherein all of the hydrophilic regions are interconnected and in fluid communication throughout the fabric and all of the hydrophobic regions are isolated from each other throughout the fabric.

11. The fabric of claim 10 , wherein the hydrophilic regions occupy greater than 50% of a total surface area of the inner and outer surfaces of the fabric.

12. The fabric of claim 11 , wherein the hydrophilic regions occupy about 60% of said total surface area.

13. The fabric of claim 10 , wherein the hydrophobic regions are substantially similar in shape and the hydrophilic regions surround the triangular shape of each hydrophobic region at a substantially uniform width.

14. The fabric of claim 13 , wherein:
the triangular shape of each hydrophobic region is an equilateral triangle with sides having a length of about 6 mm; and
said substantially uniform width of the hydrophilic regions is about 2 mm.

15. The fabric of claim 10 , further comprising:
a hydrophilic material having said inner and outer surface and capable of wicking water from the inner surface to the outer surface; and
said hydrophobic regions are treated with a water-repellant composition.

16. The fabric of claim 15 , wherein the water-repellant composition is a silicone composition.

17. The fabric of claim 10 , further comprising:
a hydrophobic material having said inner and outer surface and that is generally impermeable to water from the inner surface to the outer surface; and
said hydrophilic regions are treated with a hydrophilic composition.

18. The fabric of claim 10 , wherein a composition that is either hydrophilic or hydrophobic is applied to the fabric in said repeating pattern to form said hydrophilic and hydrophobic regions.

19. The fabric of claim 18 , wherein said composition is applied by a printing operation on one of said inner and outer surface sufficient so that said composition penetrates to the other of said inner and outer surface.

20. A garment comprising:
a material having an inner surface and an outer surface and having a repeating pattern of hydrophobic regions and hydrophilic regions, the hydrophilic regions configured to wick water from the inner surface to the outer surface of the material, and the hydrophobic regions comprised of a water-repellant composition, the hydrophilic regions forming a web of interconnected legs, and all of the hydrophobic regions isolated from each other by the interconnected legs.
