Synthetic leather, method for its manufacture, and its use

Abstract

A synthetic leather including a microfiber nonwoven has an adhesive on one surface and a layer of open-pore polyurethane foam thereon, wherein the surface of the polyurethane foam layer facing away from the microfiber nonwoven is obtained by splitting. The synthetic leather is manufacturable by a simple method in which little waste occurs. Further processing preferably takes place by back-injection in an injection molding tool.

1 . A synthetic leather comprising: 
 a microfiber nonwoven having a first surface;    an adhesive on the first surface; and    a layer of open-pore polyurethane foam on the adhesive, a surface of the polyurethane foam layer facing away from the microfiber nonwoven being split.    
   
   
       2 . The synthetic leather as recited in  claim 1  wherein the microfiber nonwoven is a split-fiber nonwoven.  
   
   
       3 . The synthetic leather as recited in  claim 2  wherein the split-fiber nonwoven has polyester or polyamide filaments or fibers.  
   
   
       4 . The synthetic leather as recited in  claim 1  wherein the adhesive layer comprises a thermosetting plastic.  
   
   
       5 . The synthetic leather as recited in  claim 4  wherein the thermosetting plastic is polyurethane.  
   
   
       6 . The synthetic leather as recited in  claim 1  wherein the open-pore polyurethane foam is made of aliphatic polyurethane.  
   
   
       7 . A method for manufacturing a synthetic leather comprising the following steps: 
 applying an adhesive layer to a microfiber nonwoven;    applying a layer of open-pore polyurethane foam to the adhesive layer;    applying another adhesive layer to the open-pore polyurethane foam layer;    applying another microfiber nonwoven to the second adhesive layer; and    splitting the composite thus produced in an area of the open-pore polyurethane foam layer.    
   
   
       8 . The method as recited in  claim 7  further comprising napping the surfaces of the open-pore polyurethane foam layer produced by the splitting.  
   
   
       9 . A back-injectable decorative material comprising the synthetic leather as recited in  claim 1 .  
   
   
       10 . An automobile interior material comprising the synthetic leather as recited in  claim 1 .  
   
   
       11 . An upholstering item of sitting furniture comprising the synthetic leather as recited in  claim 1 .  
   
   
       12 . The upholstering item as recited in  claim 11  wherein the sitting furniture is a car seat.
