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.

Claims

1. Material for a shoe upper, in particular for soccer shoes, comprising:

(a) an inner polyurethane layer;

(b) an outer polyurethane layer; and

(c) a textile reinforcing layer comprising apertures, which is arranged between the inner polyurethane layer and the outer polyurethane layer,

wherein the inner polyurethane layer and the outer polyurethane layer comprise thermoset polyurethane and are connected to each other through a plurality of the apertures of the textile reinforcing layer and,

wherein at least one of the inner polyurethane layer and the outer polyurethane layer comprises at least three polyurethane sublayers.

2. The material for a shoe upper of claim 1, wherein the textile reinforcing layer comprises a non-thermoplastic material.

3. The material for a shoe upper of claim 1, wherein at least one sublayer of the at least three polyurethane sublayers has a thickness of about 0.03-0.04 mm.

4. The material for a shoe upper of claim 3, wherein the at least one sublayer is a soft polyurethane layer.

5. The material for a shoe upper of claim 1, wherein one sublayer of the at least three polyurethane sublayers has a lower melting point and is arranged closer to the textile reinforcing layer than the other sublayers of the at least three polyurethane sublayers.

6. The material for a shoe upper of claim 5, wherein a melting point of the one sublayer is between about 100°

C. and about 150°

C., and a melting point of the other sublayers of the at least three polyurethane sublayers is between about 150°

C. and about 200°

C.

7. A shoe upper comprising at least one material of claim 1.

8. A shoe upper comprising at least two materials of claim 1, wherein the at least two materials are arranged in different zones of the shoe upper.

9. Material for a shoe upper, in particular for soccer shoes, comprising:

(a) an inner polyurethane layer;

(b) an outer polyurethane layer; and

(c) a textile reinforcing layer comprising apertures, which is arranged between the inner polyurethane layer and the outer polyurethane layer,

wherein the inner polyurethane layer and the outer polyurethane layer comprise thermoset polyurethane and are connected to each other through a plurality of the apertures of the textile reinforcing layer,

wherein at least one of the inner polyurethane layer and the outer polyurethane layer comprises at least three polyurethane sublayers, and

wherein one sublayer of the at least three polyurethane sublayers has a lower melting point and is arranged closer to the textile reinforcing layer than the other sublayers of the at least three polyurethane sublayers.

10. The material for a shoe upper of claim 9, wherein the textile reinforcing layer comprises a non-thermoplastic material.

11. The material for a shoe upper of claim 9, wherein at least one sublayer of the at least three polyurethane sublayers has a thickness of about 0.03-0.04 mm.

12. The material for a shoe upper of claim 11, wherein the at least one sublayer is a soft polyurethane layer.

13. The material for a shoe upper of claim 9, wherein a melting point of the one sublayer is between about 100°

C. and about 150°
