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:
- cutting a leather material to form leather material particles comprising collagen fiber bundles;
- screening the-leather material particles to obtain screened leather material particles that are smaller than a size of screening apertures used;
- combining the screened leather material particles with a fluid to form a solution, wherein the collagen fiber bundles of the screened the leather material particles absorb at least a portion of the fluid;
- adding a polymer latex 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.
