<p>Provided is a highly-moldable, high-shrink polyethylene fiber that is highly resistant to cutting and has excellent low-temperature workability. At the temperatures at which resulting products are used, i.e. near room temperature, the provided polyethylene fiber has excellent dimensional stability. Also, said polyethylene fiber has a high contraction ratio and high stress when worked at temperatures much lower than the melting point of polyethylene. The limiting viscosity (?) of the provided polyethylene fiber is between 0.8 and 4.9 dL/g, and the thermal stress thereof is at most 0.05 cN/dtex at 40°C and between 0.05 and 0.25 cN/dtex at 70°C. The repeating unit of said polyethylene fiber primarily comprises ethylene. Also provided are a string-like material, a rope, a woven or knit material, gloves, and a protective cover using the provided polyethylene fiber.</p> |
