Methods and systems for forming composite fibers

This invention describes a method to create new composite fibers from dissolved cellulose, which can be sourced from recycled materials like old clothes, and a second dissolved material. The claims outline two distinct ways to form these fibers: either by coiling the combined materials around a spinning carbon rod, or by coextruding them so one material forms a core and the other a sheath.

Why it matters: Filed before the surge in demand for circular economy solutions and sustainable textiles. Advances in chemical recycling and composite fiber manufacturing could make this process more efficient.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedChemical dissolution, specialized extrusion, carbonization furnace.
