Abstract

Described are materials for a shoe upper, in particular for soccer shoes, with a particularly low weight and improved tensile strength. The material includes a first foil layer and a textile reinforcement layer, which is at least partially laminated with the first foil layer. The textile reinforcement layer includes a first textile material with at least three axes, each axis defining an orientation of a set of essentially parallel yarn-portions in the textile material.

First claim

That which is claimed is:

1. Material for a shoe upper comprising:
(a) a first foil layer; and
(b) a textile reinforcement layer at least partly laminated with the first foil layer, wherein the first foil layer comprises an inner sublayer and an outer sublayer, wherein the inner sublayer is adjacent to the textile reinforcement layer and comprises polyurethane, and wherein the inner sublayer comprises a lower melting point than the outer sublayer,
wherein the textile reinforcement layer comprises a first region comprising a first textile material and a second region comprising a second textile material different from the first textile material, and wherein a surface structure of the material for the shoe upper in the first region is different from a surface structure of the material for the shoe upper in the second region,
wherein the first textile material comprises at least three axes,
wherein a first axis defines an orientation of a first set of yarns in the first textile material that extend continuously and essentially parallel to the first axis when the first textile material is arranged in a flat configuration,
wherein a second axis defines an orientation of a second set of yarns in the first textile material that extend continuously and essentially parallel to the second axis when the first textile material is arranged in the flat configuration,
wherein a third axis defines an orientation of a third set of yarns in the first textile material that extend continuously and essentially parallel to the third axis when the first textile material is arranged in the flat configuration, and
wherein a tensile strength of the first textile material in a direction parallel to the first axis is different from a tensile strength of the first textile material in a direction parallel to the second axis.

2. The material for a shoe upper of claim 1 , wherein the first textile material of the textile reinforcement layer is a woven material.

3. The material for a shoe upper of claim 1 , wherein the first textile material comprises multiple sublayers of woven textile material that are interconnected to each other.

4. The material for a shoe upper of claim 1 , wherein the yarns in the first textile material comprise at least one of a thermoset polyester, thermoset polyurethane, thermoplastic polyester, thermoplastic polyurethane, carbon, aramid, polyamide, nylon, basalt, ultra-high molecular weight polyethylene, polymers with nanotubes or graphene, liquid crystal polymers, polyethylene naphtalathe, polyvinylidene chloride, polyparaphenylene-benzobisethiazole or electrical conductive material.

5. The material for a shoe upper of claim 1 , wherein a yarn thickness of the first set of yarns is different from a yarn thickness of the second set of yarns.

6. The material for a shoe upper of claim 1 , wherein the material is pre-shaped into a desired three-dimensional shape.

7. The material for a shoe upper of claim 6 , wherein the textile reinforcement layer is pre-shaped prior to incorporation into a shoe upper.

8. A shoe upper comprising the material of claim 1 .

9. A shoe comprising the shoe upper of claim 8 .

10. The material for a shoe upper of claim 1 , wherein the first region comprises a first textile material, and wherein the
second region comprises a second textile material, the second textile material
different from the first textile material.

11. Material for a shoe upper comprising:
(a) a first foil layer;
(b) a textile reinforcement layer at least partly laminated with the first foil layer; and
(c) a second foil layer at least partially laminated with the textile reinforcement layer, the second foil layer arranged at a side of the textile reinforcement layer opposite the first foil layer,
wherein at least one of the first foil layer or the second foil layer comprise an inner sublayer and an outer sublayer, wherein the inner sublayer comprises polyurethane, and wherein the inner sublayer comprises a lower melting point than the outer sublayer,
wherein the textile reinforcement layer comprises a first region and a second region, the first region and the second region each comprising at least three axes, each axis defining an orientation of a set of essentially parallel yarn-portions in the textile reinforcement layer,
wherein for each set of yarn-portions, each yarn-portion comprises a yarn extending continuously and essentially parallel to the respective axis,
wherein the yarns of the set of yarn-portions in the orientation essentially parallel to a first axis of the at least three axes of the first region comprise a first material and the yarns of the set of yarn-portions in the orientation essentially parallel to a second axis of the at least three axes of the second region comprise a second material different from the first material such that the yarns essentially parallel to the first axis differ in at least one characteristic from the yarns essentially parallel to the second axis,
wherein a thickness of the textile reinforcement layer in the first region is different from a thickness of the textile reinforcement layer in the second region, and
wherein the textile reinforcement layer comprises apertures and wherein the first foil layer and the second foil layer are bonded to each other through the apertures of the textile reinforcement layer without adhesives.

12. The material for a shoe upper of claim 11 , wherein both the first foil layer and the second foil layer comprise a plurality of multiple sublayers.

13. The material for a shoe upper of claim 12 , wherein at least one of the plurality of sublayers of the first foil layer and at least one of the plurality of sublayers of the second foil layer comprise at least one of a thermoset polyurethane, thermoplastic polyurethane, polyester, polyisocyanate, aliphatic polyisocyanate, ethylene propylene diene monomer, silicone, polyvinyl chloride, thermoplastic elastomers, polyethylene, polylactide, or polyamide.
