Abstract

A method is provided for producing breathable leather material including the following steps: a leather-based material is provided; the leather-based material is perforated; a support body is provided; a finishing is applied to the support body such that a later visible side of the finishing is facing the support body and the finishing is transferred to the surface of the perforated leather-based material and removed from the support body.

First claim

What is claimed is:

1. A method for producing a breathable leather material, the method comprising the acts of:
providing a leather-based material;
perforating the leather-based material;
providing a support body;
applying a finishing to the support body so that a later visible side of the finishing faces the support body; and
transferring the finishing to a surface of the perforated leather-based material and removing the support body.

2. The method according to claim 1 , wherein the finishing is applied punctiformly to the support body.

3. The method according to claim 2 , wherein the finishing is applied punctiformly to the support body by a screen-printing process.

4. The method according to claim 1 , wherein the support body is perforated before applying the finishing.

5. The method according to claim 2 , wherein the support body is perforated before applying the finishing.

6. The method according to claim 1 , wherein the support body and the finishing are perforated before the finishing is transferred.

7. The method according to claim 1 , wherein the support body and/or the finishing is heated to transfer the finishing.

8. The method according to claim 1 , wherein an exposed side of the finishing is pressed to the surface of the leather-based material to transfer the finishing.

9. The method according to claim 7 , wherein an exposed side of the finishing is pressed to the surface of the leather-based material to transfer the finishing.

10. The method according to claim 1 , wherein the finishing comprises a primer, a coloring preparation and/or a topcoat.

11. The method according to claim 1 , wherein the leather-based material is a natural leather and is tanned, stretched and/or walked before being provided.

12. The method according to claim 1 , wherein the breathable leather material forms a molded skin.

13. The method according to claim 1 , wherein the breathable leather material forms a motor vehicle trim element.

14. The method according to claim 1 , wherein the breathable leather material forms one or more of an instrument panel, a center console, a door trim, or a seat cover.
