A polytetrafluoroethylene textile and manufacturing method thereof is disclosed. a pretreatment process is performed on a plurality of polytetrafluoroethylene yarns. In the pretreatment process, a step of extending the polytetrafluoroethylene yarns are extended, the polytetrafluoroethylene yarns are knitted into a polytetrafluoroethylene fabric, the shape of the polytetrafluoroethylene fabric is fixed, and the polytetrafluoroethylene fabric are de-knitted into the polytetrafluoroethylene yarns with a plurality of knit-assisting parts. A second knitting process is performed to knit the polytetrafluoroethylene yarns and a plurality of artificial yarns together to obtain the polytetrafluoroethylene textile.

Actuators (artificial muscles) comprising twist-spun nanofiber twist-inserted polymer fibers generate tensile actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize coiled polymer fibers and can be either neat or comprising a guest. In some embodiments, the coiled polymer fibers actuator can be incorporated into an article, such as a textile, braid, clothing, smart packaging, or a mechanical system, and the coiled polymer fiber in the coiled polymer fiber actuator can have a stroke amplification factor of 5 or greater.

In a method of making a carbon fiber, PAN (poly(acrylonitrile-co methacrylic acid)) is dissolved into a solvent to form a PAN solution. The PAN solution is extruded through a spinneret, thereby generating at least one precursor fiber. The precursor fiber is passed through a cold gelation medium, thereby causing the precursor fiber to gel. The precursor fiber is drawn to a predetermined draw ratio. The precursor fiber is continuously stabilized to form a stabilized fiber. The stabilized fiber is continuously carbonized thereby generating the carbon fiber. The carbon fiber is wound onto a spool. A carbon fiber has a fiber tensile strength in a range of 5.5 GPa to 5.83 GPa. The carbon fiber has a fiber tensile modulus in a range of 350 GPa to 375 GPa. The carbon fiber also has an effective diameter in a range of 5.1 m to 5.2 m.
