20220396902 · 2022-12-15 · ·

A manufactured shearling material comprises a leather layer and a knitted wool layer laminated together. The leather layer may be made by grinding up waste/scrap leather and adhering it to a backing, and giving texture (or texturizing) a surface to give the surface a particular feel (e.g., a suede feel). The scrap leather may be from various animals, including cows, sheep, etc. The knitted wool layer may comprise recycled wool clippings organized together to simulate the fur surface of natural shearling, and the wool clippings may be combined with one or more additional materials (e.g., fur, cotton, polyester, Tencel, silk, etc.) at various blends (e.g., 80/20 blend of wool and Tencel) to control the feel, aesthetics, and/or functionality, etc. of the knitted wool layer. Furs, hair, or other materials other may be utilized instead of the recycled wool clippings. An additional layer may be provided on top of the leather, with such additional layer being a synthetic recycled fabric.
