METHOD FOR PRODUCING A COMPOSITE MATERIAL AND COMPOSITE MATERIAL
The invention relates to a process for the production of a composite material, by bonding a supportive layer to an upper layer (1) made of polyurethane or flexible PVC, where the supportive layer (2) is a textile material, e.g. woven fabric, knitted fabric or nonwoven microfiber fabric, or a leather...

description | The invention relates to a process for the production of a composite material, by bonding a supportive layer to an upper layer (1) made of polyurethane or flexible PVC, where the supportive layer (2) is a textile material, e.g. woven fabric, knitted fabric or nonwoven microfiber fabric, or a leather, in particular a split cowhide leather, and the upper layer (1) comprises, bonded to one another, a number of polyurethane layers or a number of flexible PVC layers (1′, 1″). The invention provides thatin the composite of upper layer (1) and supportive layer (2), proceeding from the surface of the upper layer (1), channel-shaped cavities (6) for the passage of water vapor and/or air are formed via ablation of material by a laser in a manner such thatat least some of the cavities (6) penetrate the entire thickness of the material of the upper layer (1) and/or terminate before entry into that region of the volume of the supportive layer (2) that is free from the material of the upper layer (1). |
