PROBLEM TO BE SOLVED: To provide braid effectively demonstrating excellent properties of ultra high molecular weight polyethylene fibers in tensile strength-elastic modulus characteristics and also being excellent in dimension stability, abrasion resistance and handling.SOLUTION: The braid includes polyethylene fibers composed of ultra high molecular weight polyethylene, whose repeat unit is substantially ethylene, with a limiting viscosity of not less than 5 dL/g. A single yarn of the fiber in the restrained state shows the ratio of the total area of endothermic peaks to the area of the endothermic peak of the high temperature side to be 14.0:1.0-1.5:1.0 in rising temperature differential scanning calorimetry (DSC curve).COPYRIGHT: (C)2010,JPO&INPIT【課題】超高分子量ポリエチレン繊維が有する優れた強度・弾性率特性を有効に発揮させつつ、寸法安定性、耐摩耗性、取り扱い性に優れた組紐を提供する。【解決手段】 繰り返し単位が実質的にエチレンであり、極限粘度5dL/g以上の超高分子ポリエチレンからなり、拘束状態における単糸の昇温示差走査熱量測定(DSC曲線)の吸熱ピーク全体の面積と高温側の吸熱ピークの面積との比が、14.0:1.0~1.5:1.0であるポリエチレン繊維を含むことを特徴とする組紐。【選択図】なし
