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. |
