Commingled yarn, method for manufacturing the commingled yarn, and, weave fabric

A method for manufacturing a commingled yarn, the method comprising immersing a blended fiber bundle into a liquid containing a surface treatment agent and/or sizing agent, followed by drying,

• wherein the blended fiber bundle comprises a continuous thermoplastic resin fiber, a continuous reinforcing fiber, and a surface treatment agent and/or sizing agent of the continuous reinforcing fiber;
• a portion of epoxy resin as the surface treatment agent and/or sizing agent of the continuous reinforcing fiber has a content of 0.4 to 1.2% by weight, relative to a total amount of the continuous thermoplastic resin fiber and the continuous reinforcing fiber in the blended fiber bundle;
• and
• wherein a total amount of a surface treatment agent and/or sizing agent in the commingled yarn is 2.1% to 10% by weight, relative to a total amount of the continuous thermoplastic resin fiber and the continuous reinforcing fiber, and the commingled yarn has a dispersibility of the continuous thermoplastic resin fiber and the continuous reinforcing fiber of 70% or larger,
• wherein the continuous thermoplastic resin is selected from the group consisting of mixed polymetaxylylene/paraxylylene sebacamide resin, polymetaxylylene adipamide resin, polyamide 66, and combinations thereof;
• wherein the surface treatment agent and/or sizing agent of the commingled yarn is water-soluble nylon;
• and
• wherein the continuous reinforcing fiber is a carbon fiber and/or glass fiber.
