Biofabricated leather articles having zonal properties
The invention herein provides biofabricated materials having zonal properties and methods of making biofabricated materials having zonal properties.
1. An article, comprising:
a material having zonal properties, the material comprising:
a first collagen-containing material comprising collagen attached to a first fabric material, the first collagen-containing material having a first set of material properties; and
a second collagen-containing material comprising collagen attached to a second fabric material, the second collagen-containing material having a second set of material properties, wherein at least one material property within the second set of material properties has a value that is different from the same property in the first set of material properties; and
wherein an edge of the first collagen-containing material and an edge of the second collagen-containing material are disposed side-by-side in a single layer.
2. The article of claim 1 , wherein at least one of the first collagen-containing material or the second collagen-containing material comprises recombinant collagen.
3. The article of claim 2 , wherein the recombinant collagen is selected from the group consisting of recombinant bovine collagen, recombinant porcine collagen, recombinant kangaroo collagen, recombinant sheep collagen, and combinations thereof.
4. The article of claim 2 , wherein the recombinant collagen is recombinant Type III bovine collagen.
5. The article of claim 1 , wherein the first set of material properties comprises color, breathability, stretchability, tear strength, softness, rigidity, abrasion resistance, luminescence, reflectance, and fragrance; and wherein the second set of material properties comprises color, breathability, stretchability, tear strength, softness, rigidity, abrasion resistance, luminescence, reflectance, and fragrance.
6. The article of claim 1 , further comprising a substrate layer, wherein first collagen-containing material and the second collagen-containing material are bonded to the substrate layer.
7. The article of claim 6 , wherein the substrate layer comprises a fabric.
8. The article of claim 1 , wherein the first collagen-containing material comprises a first dried collagen paste, and wherein the second collagen-containing material comprises a second dried collagen paste.
9. The article of claim 8 , wherein the first dried collagen paste and the second dried collagen paste comprise fibrillated collagen.
10. The article of claim 1 , further comprising a gap between the edge of the first collagen-containing material and the edge of the second collagen-containing material, wherein the gap is filled with a collagen material.
11. The article of claim 1 , wherein the second collagen-containing material surrounds the edge of the first collagen-containing material.
12. The article of claim 1 , wherein the collagen attached to the first fabric material and the collagen attached to the second fabric material comprise fibrillated collagen.
13. A method of making a material having zonal properties,
the method comprising:
placing a first fabric material on a surface;
placing a second fabric material with different properties next to the first fabric material;
applying an aqueous solution of collagen over the two fabric materials to form:
a first collagen-containing material comprising collagen and the first fabric material, and
a second collagen-containing material comprising collagen and the second fabric material; and
drying the first collagen-containing material and the second collagen-containing material to form the material having zonal properties; wherein:
the first collagen-containing material has a first set of material properties;
the second collagen-containing material has a second set of material properties;
at least one material property within the second set of material properties has a value that is different from the same property in the first set of material properties; and
an edge of the first collagen-containing material and an edge of the second collagen-containing material are disposed side-by-side in a single layer.
14. The method of claim 13 , wherein the first fabric material and the second fabric material are fibrous materials.
15. The method of claim 13 , wherein the aqueous solution of collagen is a single aqueous solution of collagen that is poured over the first fabric material and the second fabric material.
