The purpose of the present invention is to provide polyketone fibers having excellent strength and water resistance, which are manufactured from a polyketone solution prepared from a copolymer of carbon monoxide, ethylene, and propylene, and a manufacturing method therefor. The industrial polyketone fibers manufactured according to the present invention have excellent strength, elongation, water resistance, heat resistance, and thermal conductivity, and thus are suitable for the use for marine ropes, hoses, protective products, Geotextile, fibers for enhancing FRP composite materials, cables, fishing nets, air bags, heat insulators, seat belts, safety nets, roung sling, flying film materials, non-woven fabrics, spun bonds, conveyor belts, flexible containers, fishing lines, sports cords, carbon fiber composite materials, longlines, carpets.
