Abstract
A leather substrate formed from waste leather and its method of production, particularly a leather substrate made up substantially of a collagen fibril matrix.
Claims17
A method of forming a leather substrate material comprising:
- processing a leather material to form leather material particles comprising collagen fiber bundles;
- combining the leather material particles with a fluid to form a solution, wherein the collagen fiber bundles of the leather material particles absorb at least a portion of the fluid;
- adding a polymer latex to the solution;
- adding a dispersion aid to the solution;
- causing the collagen fiber bundles to be dispersed in the solution;
- and
- removing at least a portion of the fluid from the solution to form a leather substrate, wherein the leather substrate exhibits a tear resistance of greater than about 20 Newtons when tested in accordance with ASTM D 4704.

A method of forming a leather substrate material comprising:
- processing a leather material to form leather material particles, wherein the leather material particles comprise collagen fiber bundles;
- at least partially distressing the collagen bundles of the leather material particles by adding a fluid to the leather material particles;
- causing the collagen fiber bundles to be dispersed throughout the solution;
- combining the leather material particles and fluid with a dispersion aid;
- combining the leather material particles and fluid with a polymer latex to provide a latex solution;
- and
- removing at least a portion of fluid from the latex solution to form a leather substrate wherein the leather substrate exhibits a tear resistance of greater than about 20 Newtons when tested in accordance with ASTM D 4704.
