Fiber comprising alicyclic-structure-containing polymer, and method for manufacturing same |
摘要 |
The invention is: a fiber produced by forming a fiber using pellets, and annealing the fiber at 150 to 220° C., the pellets being formed of a resin powder of a cycloolefin polymer, the resin powder having a loose bulk density of 0.3 to 0.6 g/cc when measured using 100 cc of the resin powder: a method for producing the fiber. The invention provides a method for producing a cycloolefin polymer fiber that exhibits good productivity and strength during spinning, and a low thermal shrinkage ratio. |

1. A method for producing a fiber comprising forming a fiber using pellets at a spinning speed of 700 m/min or more, and annealing the fiber at 150 to 220° C., the pellets being formed of a resin powder of a cycloolefin polymer, the resin powder having a loose bulk density of 0.3 to 0.6 g/cc when measured using 100 cc of the resin powder. |
