  • Commingled yarn, method for manufacturing the commingled yarn, and, weave fabric
    Patent number: 11236446
    Abstract: Provided is a commingled yarn having a dispersing property and having a smaller amount of voids, a method for manufacturing the commingled yarn, and a weave fabric using the commingled yarn. The commingled yarn comprises a continuous thermoplastic resin fiber, a continuous reinforcing fiber, and a surface treatment agent and/or sizing agent, comprises the surface treatment agent and/or sizing agent in a content of 2.0% by weight or more, relative to a total amount of the continuous thermoplastic resin fiber and the continuous reinforcing fiber, and has a dispersibility of the continuous thermoplastic resin fiber and the continuous reinforcing fiber of 70% or larger.
    Type: Grant
    Filed: October 10, 2014

  • Method for manufacturing commingled yarn, commingled yarn, wind-up article, and, woven fabric
    Patent number: 9994976
    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.
