FIBER FOR ACTUATORS, AND ACTUATOR AND FIBER PRODUCT USING SAME

An actuator fiber is made of a thermoplastic resin and has a coil spring shape. A spring index D/d of 1.7 or more when an average diameter of a coil portion is represented by D and a fiber diameter is represented by d. A glass transition point measured by a differential scanning calorimeter may be 1...

Zusammenfassung:	An actuator fiber is made of a thermoplastic resin and has a coil spring shape. A spring index D/d of 1.7 or more when an average diameter of a coil portion is represented by D and a fiber diameter is represented by d. A glass transition point measured by a differential scanning calorimeter may be 150° C. or lower.
