Garments having auxetic foam layers
A garment is provided that has a support region and a foam pad at the region. The foam pads has at least one auxetic foam layer. A garment is also provided that includes at least one auxetic foam layer.
1. A garment comprising:
a breast covering portion comprising a pair of breast cups; and
each breast cup comprising a pad having at least one auxetic foam layer, the pad having an inner surface adjacent the breast when worn, and an outer surface.
2. The garment of claim 1 , wherein said at least one auxetic foam layer comprises one or more layers of a foam selected from the group consisting of polymer auxetic foam layer, a metallic auxetic foam layer, and combinations thereof.
3. The garment of claim 1 , wherein said pad further comprises at least one non-auxetic foam layer.
4. The garment of claim 3 , wherein said at least one auxetic foam layer and said at least one non-auxetic foam layer are configured so that said pad maintains a constant thickness when stretched in at least one direction.
5. The garment of claim 1 , wherein said pad further comprises one or more fabric layers covering at least a portion of at least one of the inner and the outer surface.
6. The garment of claim 1 , wherein the garment is selected from the group consisting of a brassiere, a camisole, a bathing suit, and a leotard.
7. The garment of claim 1 , wherein said at least one auxetic foam layer is configured to release a chemical agent when stretched to an open position.
8. The garment of claim 1 , wherein said at least one auxetic foam layer has a negative through-thickness Poisson's ratio.
9. The garment of claim 8 , wherein said negative through-thickness Poisson's ratio is in a range of about 0.0 to about −1.0.
10. The garment of claim 8 , wherein said at least one auxetic foam layer has a negative in-plane Poisson's ratio.
11. The garment of claim 1 , wherein said at least one auxetic foam layer has a negative in-plane Poisson's ratio.
12. The garment of claim 11 , wherein said negative in-plane Poisson's ratio in a range of about 0.0 to about −1.0.
13. The garment of claim 11 , wherein said at least one auxetic foam layer has a negative through-thickness Poisson's ratio.
14. The garment of claim 1 , wherein said at least one auxetic foam layer comprises a molded foam layer having a desired shape.
15. The garment of claim 1 , wherein said at least one auxetic foam layer comprises a machined foam layer having a desired shape.
16. The garment of claim 1 , wherein said at least one auxetic foam layer comprises a machined and molded foam layer having a desired shape.
17. A brassiere, comprising:
a pair of breast receiving cups, each of the breast receiving cups comprising a pad having at least one auxetic foam layer, the pad having an inner surface adjacent the breast when worn, and an outer surface;
a pair of side wing panels, each side wing panel being connected to one of the breast receiving cups; and
a pair of shoulder straps, each shoulder strap being connected to one of the breast receiving cups.
18. The brassiere of claim 17 , wherein said at least one auxetic foam layer comprises one or more layers of a foam selected from the group consisting of polymer auxetic foam layer, a metallic auxetic foam layer, and combinations thereof.
19. The brassiere of claim 17 , wherein said pad further comprises at least one non-auxetic foam layer.
20. The brassiere of claim 19 , wherein said at least one auxetic foam layer and said at least one non-auxetic foam layer are configured so that said pad maintains a constant thickness when stretched in at least one direction.
21. The brassiere of claim 17 , wherein said pad further comprises one or more fabric layers covering ay least a portion of at least one of the inner and the outer surface.
22. The brassiere of claim 17 , wherein said at least one auxetic foam layer is configured to release a chemical agent when stretched to an open position.
23. The brassiere of claim 17 , wherein said at least one auxetic foam layer has a negative through-thickness Poisson's ratio.
24. The brassiere of claim 23 , wherein said negative through-thickness Poisson's ratio is in a range of about 0.0 to about −1.0.
25. The brassiere of claim 17 , wherein said at least one auxetic foam layer has a negative in-plane Poisson's ratio.
26. The brassiere of claim 25 , wherein said negative in-plane Poisson's ratio in a range of about 0.0 to about −1.0.
