Abstract

Described are materials for a shoe upper, in particular for soccer shoes, with a particularly low weight. The material includes an inner polyurethane layer, an outer polyurethane layer, and a textile reinforcing layer. The textile reinforcing layer is arranged between the inner polyurethane layer and the outer polyurethane layer. The inner polyurethane layer and the outer polyurethane layer comprise thermoset polyurethane. The textile reinforcing layer comprises apertures through which the inner polyurethane layer and the outer polyurethane layer are connected to each other.

First claim

The which is claimed is:

1. A material for a shoe upper, the material comprising:
a first polyurethane layer;
a second polyurethane layer; and
a textile reinforcing layer between the first polyurethane layer and the second polyurethane layer, wherein the textile reinforcing layer comprises a plurality of apertures arranged in a first zone and a second zone of the textile reinforcing layer,
wherein, in the first zone, the first polyurethane layer and the second polyurethane layer are bonded together through the plurality of apertures of the textile reinforcing layer,
wherein, in the second zone, the first polyurethane layer and the second polyurethane layer are unconnected,
wherein the first polyurethane layer contacts the textile reinforcing layer in the first zone and the second zone, and
wherein the second polyurethane layer contacts the textile reinforcing layer in the first zone and the second zone.

2. The material of claim 1 , wherein at least one of the first polyurethane layer and the second polyurethane layer comprises a plurality of sublayers.

3. The material of claim 2 , wherein a first sublayer of the plurality of sublayers comprises a first melting point and a second sublayer of the plurality of sublayers comprises a second melting point greater than the first melting point.

4. The material of claim 3 , wherein the first sublayer is arranged closer to the textile reinforcing layer than the second sublayer.

5. The material of claim 1 , wherein at least one of the first polyurethane layer and the second polyurethane layer further comprises aliphatic isocyanate or a mixture of polyester and polyether.

6. The material of claim 1 , wherein the first polyurethane layer and the second polyurethane layer comprise thermoset polyurethane.

7. The material of claim 1 , wherein the textile reinforcing layer comprises a non-thermoplastic material.

8. The material of claim 1 , wherein the textile reinforcing layer comprises a mesh material.

9. The material of claim 1 , wherein at least one of the first polyurethane layer and the second polyurethane layer further comprises a polyurethane film.

10. The material of claim 1 , further comprising a cushioning material in at least one of the apertures in the second zone of the textile reinforcing layer.

11. The material of claim 10 , wherein the cushioning material comprises polyurethane foam or compressed air.

12. The material of claim 1 , wherein the textile reinforcing layer comprises a first thickness at the first zone and a second thickness at the second zone, wherein the second thickness is larger than the first thickness.

13. The material of claim 1 , wherein the plurality of apertures of the textile reinforcing layer comprise an area of about 0.25 mm2 to about 9 mm2.

14. A shoe upper comprising:
a first material arranged on at least a first area of the shoe upper, the first material comprising:
a textile reinforcing layer between an inner polyurethane layer and an outer polyurethane layer,
wherein the textile reinforcing layer comprises a plurality of apertures arranged in a first zone and a second zone of the textile reinforcing layer,
wherein the inner polyurethane layer and the outer polyurethane layer are bonded together through the apertures of the textile reinforcing layer in the first zone,
wherein the inner polyurethane layer and the outer polyurethane layer are unconnected in the second zone,
wherein the inner polyurethane layer contacts the textile reinforcing layer in the first zone and the second zone, and
wherein the outer polyurethane layer contacts the textile reinforcing layer in the first zone and the second zone.

15. The shoe upper of claim 14 , wherein the textile reinforcing layer is a first textile reinforcing layer, wherein the inner polyurethane layer is a first inner polyurethane layer, and wherein the outer polyurethane layer is a first outer polyurethane layer, wherein the shoe upper further comprises:
a second material arranged on at least a second area of the shoe upper, the second material comprising:
a second textile reinforcing layer between a second inner polyurethane layer and a second outer polyurethane layer and comprises a plurality of apertures, wherein the second inner polyurethane layer and the second outer polyurethane layer are bonded together through the plurality of apertures of the second textile reinforcing layer,
wherein the second area of the shoe upper is different from the first area of the shoe upper, and
wherein the textile reinforcing layer of the first material is different from the second textile reinforcing layer of the second material.

16. The shoe upper of claim 15 , further comprising a cushioning material in at least one of the apertures in the second zone of the second textile reinforcing layer.

17. The shoe upper of claim 16 , wherein the cushioning material comprises polyurethane foam or compressed air.

18. The shoe upper of claim 14 , wherein the first area of the shoe upper comprises a mid-foot area of the shoe upper.

19. A shoe, comprising the shoe upper of claim 14 and a sole.
