<p>PROBLEM TO BE SOLVED: To provide a polyethylene fiber that can suitably be utilized in an area of clothing having an excellent handleability and processability while having an excellent cold-feeling.SOLUTION: Provided is a polyethylene fiber which is a fiber having a polyethylene as the major constituent, and is characterized in that the polyethylene has an intrinsic viscosity of 0.8 to 1.7, a strength at break of 2 to 8 cN/dtex, and a boiling water shrinkage percentage of in a range of 2 to 5%. Furthermore it is preferred that the fiber cross section shape is flat. And the method for producing said polyethylene fiber is characterized in melt-spinning and drawing a resin having a polyethylene of intrinsic viscosity of 0.8 to 1.7 as the major constituent, and bringing it into contact with a heat medium to perform heat set.</p> |
