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.
Claims5
A leather substrate formed by a process comprising:
- processing a leather material using a cutting technique to form leather material particles;
- combining the leather material particles with a fluid to form a solution;
- adding a polymer latex to the solution;
- adding a dispersion aid to the solution;
- and
- removing at least a portion of the fluid from the solution to form a leather substrate.
3 more elements
A method of forming a leather substrate material comprising:
- processing a source 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 comprising polymer additives to the solution;
- adding a dispersion aid to the solution;
- causing the collagen fiber bundles to separate into fibrils by dispersing the collagen fiber bundles in the solution;
- removing at least a portion of the fluid from the solution;
- and
- consolidating the collagen fiber bundles to form the leather substrate material.
