Abstract
Provided is a method for manufacturing a commingled yarn that is capable of keeping a high level of dispersion of the continuous reinforcing fiber and the continuous resin fiber, moderately flexible, and less likely to cause fiber separation, and a commingled yarn a wind-up article and a woven fabric. The method for manufacturing a commingled yarn includes commingling a thermoplastic resin fiber having a treatment agent for the thermoplastic resin fiber on a surface thereof, and a continuous reinforcing fiber having a treatment agent for the continuous reinforcing fiber on a surface thereof, and heating the commingled fibers at a temperature in a range from a melting point of the thermoplastic resin composing the thermoplastic resin fiber, up to 30K higher than the melting point.
