Claims8
An artificial leather structure, comprising:
- a woven layer;
- a porous elastomer layer disposed on the woven layer and comprising a plurality of holes;
- and
- a nonwoven layer disposed on the porous elastomer layer;
- wherein the porous elastomer layer is adhered to the woven layer and the nonwoven layer;
- wherein the plurality of holes are columnar holes penetrating the porous elastomer layer but not penetrating through the woven layer or the nonwoven layer;
- wherein the material of the porous elastomer layer is thermoplastic polyurethane (TPU), the melting point of the porous elastomer layer is from about 90° C. to about 130° C., and the Shore A hardness of the porous elastomer layer is from about 45A to about 60A;
- and
- wherein the material of the nonwoven layer is TPU, the melting point of the nonwoven layer is from about 130° C. to about 190° C., and the Shore A hardness of the nonwoven layer is from about 50 A to about 80 A.
