Abstract

Athletic apparel, including compression garments and athletic footwear, is disclosed as capable of monitoring the wear of compression fabric and/or cushioning material by attaching a performance gauge onto the apparel. The performance gauge includes microcapsules that contain a colorless dye and/or a co-reactant, wherein the microcapsules can breakdown in concert with the wear and degradation of the compression fabric or cushioning material, thereby allowing the dye and co-reactant to mix and produce color indication. As the wear of the fabric and cushioning material increases, more microcapsules breakdown resulting in a progression of color change visible through additional layers on the performance gauge, or by the fabric and/or cushioning material. The microcapsules can be engineered to breakdown based on any variation of factors that correspond to the degradation of compressive fabric and cushioning material, including shear force, tension, impact force, and/or exposure to high temperature and water.

Claims

1. A performance gauge that provides for monitoring fabric degradation and/or cushioning material degradation, comprising:

a body that can be affixed to fabric and/or cushioning material;

a first plurality of microcapsules embedded within said body, each microcapsule of the first plurality of microcapsules having (a) a first outer shell encompassing a first inner volume and (b) a dye that is contained within said first inner volume, wherein said dye can escape the first inner volume upon rupture of the first outer shell; and

a second plurality of microcapsules embedded within said body, each microcapsule of the second plurality of microcapsules having (a) a second outer shell encompassing a second inner volume and b) a co-reactant that is contained within said second inner volume, wherein said co-reactant can escape the second inner volume upon rupture of the second outer shell, and said co-reactant will activate with the dye upon contact therewith, to produce color indication.

2. The performance gauge defined in claim 1, wherein the first outer shell for the first plurality of microcapsules and the second outer shell for the second plurality of microcapsules will progressively rupture when subject to pressure and shear forces, impact forces, ground resultant forces, tension, friction, high temperature, and/or exposure to detergent, sweat, or water.

3. The performance gauge defined in claim 1, wherein the body includes a layer of textile, foam, or rubber, and further comprises a laminate or coating layer that absorbs and displays the color of the activated dye, said laminate or coating layer further comprising a) a hydrophobic film that is microporous and/or b) a hydrophilic film that is non-porous.

4. A footwear assembly having a footwear body and comprising the performance gauge as defined in claim 1, such that the performance gauge is attached to a cushioning material disposed on the footwear body.

5. An athletic garment that provides for monitoring fabric degradation, comprising:

a garment body having a compressive fabric, the garment body configured to conform to a portion of the wearer, the garment body having an initial elasticity; and

a performance gauge secured to the compressive fabric of the garment body, the performance gauge having;

a first plurality of microcapsules, each microcapsule of the first plurality of microcapsules having (a) a first outer shell encompassing a first inner volume and (b) a substance for color indication that is contained within said first inner volume, such that said substance can escape the first inner volume upon rupture of the first outer shell, such that the first plurality of microcapsules progressively rupture

     1) as the elasticity of the garment body reduces from the initial elasticity, and

     2) when subject to high temperature and/or exposure to detergent, sweat, or water, such that the progressive rupturing of the first plurality of microcapsules indicate progressive fabric degradation.

6. The athletic garment defined in claim 5, wherein the substance is a dye, the performance gauge further comprising a co-reactant that activates the dye upon contact therewith, to produce color indication.

7. The athletic garment defined in claim 6, wherein the performance gauge further comprises a binder layer affixed to the compressive fabric, and said first plurality of microcapsules are embedded within the binder layer.

8. The athletic garment defined in claim 7, wherein the performance gauge further comprises a laminate or coating layer affixed to the binder layer, the laminate or coating layer having a rubbery material that absorbs impact and/or shock, the laminate or coating layer configured to absorb and display the color of the activated dye.

9. The athletic garment defined in claim 6, further comprising a second plurality of microcapsules, each said microcapsule of the second plurality of microcapsules having (a) a second outer shell encompassing a second inner volume, and (b) the co-reactant contained within said second inner volume, such that said co-reactant can escape the second inner volume upon rupture of said second outer shell, such that the second plurality of microcapsules progressively rupture as the elasticity of the garment body reduces from the initial elasticity, so as to indicate progressive fabric degradation.

10. The athletic garment defined in claim 9, further comprising any combination of microcapsules of the first and second plurality of microcapsules in any size less than or equal to 100 micrometers with any outer shell thickness less than the corresponding microcapsule size.

11. The athletic garment defined in claim 5, wherein the substance is a dye, the garment body further comprising a co-reactant that activates the dye upon contact therewith, to produce color indication.

12. The athletic garment defined in claim 5, wherein the substance is a dye and the first outer shell for the first plurality of microcapsules is transparent, such that the dye is visible therein.

13. The athletic garment defined in claim 5, wherein the substance is a co-reactant activator, the performance gauge further comprising a halochromic material that is activated upon contact with the co-reactant activator, to produce color indication.

14. The athletic garment defined in claim 5, wherein the substance is a dye that is activated upon contact with a detergent stimulus, to produce color indication.

15. The athletic garment defined in claim 5, further comprising any combination of microcapsules of the first plurality of microcapsules in any size less than or equal to 100 micrometers with any outer shell thickness less than the corresponding microcapsule size.

16. The athletic garment defined in claim 5, wherein the performance gauge further comprises at least one indicating substrate that absorbs and displays the color of the activated dye.

17. The athletic garment defined in claim 16, wherein at least one indicating substrate comprises a laminate or coating with a rubbery material that absorbs impact and/or shock.

18. The athletic garment defined in claim 17, wherein at least one indicating substrate comprises a laminate or coating with a) a hydrophobic film that is microporous and/or b) a hydrophilic film that is non-porous.

19. An athletic garment that provides for monitoring fabric degradation, comprising:

a garment body having a compressive fabric, the garment body configured to conform to a portion of the wearer, the garment body having an initial elasticity; and

a performance gauge secured to the compressive fabric of the garment body, the performance gauge having;

a first plurality of microcapsules, each microcapsule of the first plurality of microcapsules having (a) a first outer shell encompassing a first inner volume, and (b) a dye that is contained within said first inner volume, such that said dye can escape the first inner volume upon rupture of the first outer shell, and

a second plurality of microcapsules, each microcapsule of the second plurality of microcapsules having (a) a second outer shell encompassing a second inner volume, and (b) a co-reactant that is contained within said second inner volume, such that said co-reactant can escape the second inner volume upon rupture of said second outer shell, and said co-reactant will activate with the dye upon contact therewith, to produce color indication, the first and second plurality of microcapsules configured to progressively rupture as the elasticity of the garment body reduces from the initial elasticity, so as to indicate progressive fabric degradation.

20. The athletic garment defined in claim 19, further comprising any combination of microcapsules of the first and second plurality of microcapsules in any size less than or equal to 100 micrometers with any outer shell thickness less than the corresponding microcapsule size.
