<p>PROBLEM TO BE SOLVED: To provide a composite fiber which can suppress detachment of a composite fiber from a fiber mixed body, a fiber formed material obtained by using the composite fiber and a production method of the fiber formed material.SOLUTION: A composite fiber 1 includes a core fiber composed of a plant fiber 3 and a thermoplastic resin fiber 5 or a thermoplastic resin powder adhered around the core fiber. A fiber formed material is produced by forming, with heating, a fiber mixture of the composite fiber 1 and a second thermoplastic resin fiber. A production method of the fiber formed material includes a step of obtaining the composite fiber 1, a step of mixing the composite fiber 1 with the second thermoplastic resin fiber to obtain the fiber mixture and a step of forming the fiber mixture by heating.</p> |
