PROBLEM TO BE SOLVED: To provide composite yarn that has a continuous reinforcement fiber and a continuous thermoplastic resin fiber continuously and uniformly mixed therein, has superior handleability to obtain a preform formed by knitting and weaving, braiding and the like, and can form a molding of a resin and rubber composite material, which shows sufficient mechanical characteristics even though being molded in a short period of time.SOLUTION: The composite yarn is formed by blending the continuous reinforcement fiber and the continuous thermoplastic resin fiber. In addition, the product RD of a single filament diameter R (μm) and a density D (g/cm) of the continuous reinforcement fiber is 5-100 μm×g/cm. |
