Abstract

See full text

The present invention provides a highly functional polyethylene fiber exhibiting reduction of change in their physical properties in a wide range of temperatures for processing for products and in a wide range of temperatures for usage as products, thereby enabling improvement of dimensional stability. In addition, the present invention provides a highly functional polyethylene fiber exhibiting a high degree of dye exhaustion to be obtained in a simple dyeing operation, and excellent color fastness. The highly functional polyethylene fiber of the present invention is characterized in that an intrinsic viscosity [η] is higher than or equal to 0.8 dL/g, and not higher than 4.9 dL/g, ethylene is substantially contained as a repeating unit thereof, and a maximum thermal shrinkage stress is less than or equal to 0.4 cN/dtex in TMA (thermo-mechanical analysis), and a thermal shrinking percentage at 100° C. is less than or equal to 2.5%.
