Abstract

A structured artificial leather material comprising a support layer and an application layer, the application layer comprising particles from a renewable raw material, which are laden with water. A method for producing such a structured artificial leather material is also provided.

First claim

What is claimed is:

1 . A structured artificial leather material comprising:
a support layer; and an overlay layer arranged on the support layer, the overlay layer comprising particles of a renewable raw material, and the particles are loaded with water.

2 . The structured artificial leather material according to claim 1 , wherein the renewable raw material includes components of coffee fruits and/or silverskin of coffee fruits.

3 . The structured artificial leather material according to claim 1 , wherein, wherein the renewable raw material is present in a quantity of at least 10 percent by weight or at least 20 percent by weight, with respect to a total weight of the overlay layer.

4 . The structured artificial leather material according to claim 1 , wherein the particles have a content of physically bound water from 1 percent by weight to 10 percent by weight or 2 percent by weight to 5 percent by weight.

5 . The structured artificial leather material according to claim 1 , wherein the particles have, on average, a diameter from 10 μm to 100 μm.

6 . The structured artificial leather material according to claim 1 , wherein the overlay layer is a foam layer.

7 . The structured artificial leather material according to claim 1 , wherein the artificial leather material comprises:
a first overlay layer; and a second overlay layer that is arranged on the first overlay layer,
wherein the first overlay layer and/or the second overlay layer comprises particles of a renewable raw material and/or silverskin of coffee fruits,
wherein the renewable raw material is present in a quantity of at least 10 percent by weight or at least 20 percent by weight,
wherein the particles are loaded with water, and
wherein the first overlay layer is an adhesive layer that joins the support layer to the second overlay layer.

8 . The structured artificial leather material according to claim 1 , wherein the structured artificial leather material has structure elements that are produced by a rupturing of the surface of the artificial leather material.

9 . A method for producing a structured artificial leather material according to claim 1 , the method comprising:
providing a support layer; providing particles from a renewable raw material; loading the particles with water; providing a first overlay layer comprising the particles; and arranging the first overlay layer on the support layer.

10 . The method for producing a structured artificial leather material according to claim 9 , wherein the method further comprises an embossing step, and the embossing step leads to a partial rupturing of the surface.
