Abstract

Disclosed herein is a knitted multi-layer fabric construction that provides the ability to cool skin to below a current temperature whether wetted or dry. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit, seamless, hosiery, flat bed, spacer, and double knits. Various finishing methods may also be employed to enhance the cooling power of the fabric.

Claims (24)

1. A multi-layered knitted cooling fabric, comprising:

a first layer formed of a first yarn;

a second layer formed of a second yarn; and

a third layer formed of a third yarn;

wherein the first yarn includes an evaporative yarn, the second yarn includes an absorbent yarn, the third yarn includes an evaporative yarn adapted to allow moisture trapped in the second layer to move to the third layer, and the second layer is arranged between the first and third layers.

2. The multi-layered knitted cooling fabric according to claim 1 , wherein the second layer is arranged adjacent the first layer.

3. The multi-layered knitted cooling fabric according to claim 1 , wherein the third layer is arranged adjacent the second layer.

4. The multi-layered knitted cooling fabric according to claim 2 , wherein the third layer is arranged adjacent the second layer.

5. The multi-layered knitted cooling fabric according to claim 1 , wherein the first yarn includes an evaporative and UV-protective yarn.

6. The multi-layered knitted cooling fabric according to claim 1 , wherein the second yarn includes a conjugated bi-component polyester and nylon yarn.

7. The multi-layered knitted cooling fabric according to claim 1 , wherein the second yarn has a wicking rate and a wicking distance more than twice that of cotton of equivalent density.

8. The multi-layered knitted cooling fabric according to claim 1 , wherein the third yarn includes an evaporative and UV-protective yarn.

9. The multi-layered knitted cooling fabric according to claim 1 , wherein the multi-layered knit cooling fabric has a density of 100 to 600 g/m 2 .

10. The multi-layered knitted cooling fabric according to claim 1 , wherein the first layer includes spandex.

11. The multi-layered knitted cooling fabric according to claim 1 , wherein the first yarn includes a conjugated bi-component polyester and nylon yarn with a star-shaped cross-section.

12. The multi-layered knitted cooling fabric according to claim 1 , wherein the fabric forms an entire garment.

13. The multi-layered knitted cooling fabric according to claim 1 , wherein the garment includes a shirt, pants, and/or shorts.

14. The multi-layered knitted cooling fabric according to claim 1 , wherein the fabric is integrated into a garment.

15. The multi-layered knitted cooling fabric according to claim 1 , wherein the multi-layered knitted cooling fabric forms a headband, a towel, and/or a hat.

16. The multi-layered knitted cooling fabric according to claim 1 , wherein the first layer is adapted to be worn against skin.

17. The multi-layered knitted cooling fabric according to claim 1 , wherein the first layer includes a combination of a stretchable synthetic yarn and the evaporative yarn.

18. The multi-layered knitted cooling fabric according to claim 1 , wherein the third layer is adapted to be exposed to an external environment.

19. The multi-layered knitted cooling fabric according to claim 1 , wherein the second layer is arranged between the first layer and the third layer.

20. The multi-layered knitted cooling fabric according to claim 1 , wherein the first layer includes hydrophobic and hydrophilic channels.
