摘要： Disclosed are a method of manufacturing high-tenacity polyethylene fiber and high-tenacity polyethylene fiber manufactured thereby. The method includes mixing polyethylene, having a molecular weight average molecular weight ranging from 200,000 to 5,000,000, with a first solvent, which is a nonvolatile organic compound, thus obtaining a gel solution having an intrinsic viscosity of 17-23 dl/g; spinning the gel solution using a die, thus forming gel fiber; immersing the gel fiber in a second solvent, which is a liquid-phase volatile organic compound, at a high temperature close to the volatile point of the second solvent, and cooling it; and jetting the second solvent, which is a gas-phase volatile organic compound, to the cooled gel fiber, thus extracting the first solvent and drawing the gel fiber at a draw ratio of 30: 1-50: 1. Through this method, high-tenacity polyethylene fiber having superior mechanical properties, including high tenacity and high elongation and excellent chemical resistance, can be manufactured.
