Beschreibung
Zusammenfassung:	Disclosed are polyketone fibers which contain a ketone unit represented by -CH2CH2-CO- as a main repeating unit, and have an intrinsic viscosity of not less than 0.5 dl/g, a crystal orientation of not less than 90%, a density of not less than 1.300 g/cm , an elastic modulus of not less than 200 cN/dtex, and a heat shrinkage of -1 to 3%. The polyketone fibers are high in strength and elastic modulus, and excellent in fatigue resistance, processability, heat resistance, dimensional stability, and, besides, adhesion, and, therefore, can be applied to the fields which require high fatigue resistance, such as tire cords, belts, hoses, ropes, etc.
