Polyetherimide-based fiber, method for manufacturing same, and fiber structure containing same |
abstract |
Provided is a polyetherimide-based fiber containing a polyetherimide resin and carbon black dispersed in the resin, wherein the content of the carbon black is 0.03 wt % or greater; the carbon black has a primary particle number-mean particle size of from 30 nm to 500 nm; and the fiber has a weight reduction rate of less than 0.5% around the glass transition point (Tg) of the polyetherimide resin, where the weight reduction rate is defined by a following formula (1).n nWeight reduction rate (%)={[(fiber weight at temperature T 1)−(fiber weight at temperature T 2)]/(fiber weight at temperature T 1)}×100 (1)n n Where T1 denotes a temperature (Tg−15° C.) that is 15° C. lower than the glass transition point (glass transition temperature) of the polyetherimide resin, and T2 denotes a temperature (Tg+25° C.) that is 25° C. higher than the glass transition point. |
