US 2026/0275579 A1 · SYSTEM AND METHOD FOR MANUFACTURE OF COLLAGEN FIBERS

Abstract

A method and system for producing biopolymer collagen fiber includes acidified collagen solution that can be piped to a vertical formation buffer bath. The collagen solution can be extruded as a stream of fibrous lines (filaments) after passing through a plurality of holes formed in a disc that can be disposed at the bottom end of the vertical formation buffer bath. Each filament can be immersed in the surrounding buffer bath and is polymerized, forming a collagen sub-filament. The resultant sub-filaments are extracted from the top of the vertical tank and gathered together into bundles to produce a collagen fiber.

Dependent claims

A method of producing a collagen biopolymer fiber, comprising the steps of:

dissolving collagen in an acid solution to form a collagen solution;
extruding the collagen solution through a plurality of holes in a spinneret located at a bottom of a vertical formation buffer bath to form a plurality of sub-fibers;
bundling at least two sub-fibers of the plurality of sub-fibers together into a collagen fiber as the at least two sub-fibers ascend the vertical formation buffer bath;
and
wherein the plurality of sub-fibers and the collagen fiber have a buoyancy such that they float from the bottom of the vertical formation buffer bath when extruded to a top of the vertical formation buffer bath.
