Abstract: Biomaterial-based elastomeric materials are disclosed, as are methods for making and using such fibrous materials. In some embodiments, a biomaterial textile composition includes a mixture of a thermoplastic elastomer and a second polymer. The biomaterial textile compositions of the disclosure are characterized by desirable combinations of material properties, e.g., elastic modulus and hardness, that make the materials especially suitable for various applications, particularly as leather analogs and similar textiles.
