NOVELTY - An application of graphene for preparation of soy protein fiber and its fabric, involves providing graphene with sheet structure of less than 10 layers. USE - Application of graphene for preparation of soy protein fiber for use in woven fabric (all claimed). ADVANTAGE - The economical method enables application of tough graphene with excellent electrical conductivity, high-temperature resistance, excellent bulkiness, flexibility and high rigidity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: modified soy protein fiber; #method for preparing modified soy protein fiber, involves oxidizing graphene with lamellar structure of less than 10 layers with an oxidizing agent, dispersing in organic solvent to form mixed graphene oxide solution, mixing with soybean protein spinning solution in the presence of hydriodic acid, and wet-spinning to obtain final product; and #woven fabric.
