A net made of a high strength polyethylene fiber was recently issued a patent. The fiber comprises a high molecular weight polyethylene consisting of a repeating unit of ethylene. It has an intrinsic viscosity number of five or larger and an average strength of 22 cN/dtex or higher. The measurement of the fiber by differential scanning calorimetry (DSC) exhibits a temperature-increasing DSC curve with at least one endothermic peak over a temperature region of 140°-148° C (on the low temperature side) and at least one endothermic peak over a temperature region of 148° C or higher (on the high temperature side).
