PROBLEM TO BE SOLVED: To provide a cord having high strength, excellent size stability, high toughness and homogeneous heat shrinking properties, and free from slackening and strain caused by an RFL treatment and vulcanization. ;SOLUTION: An intertwisted cord is obtained by intertwisting a polyketone fiber (A) having the following properties (a) to (c): (a) a tensile strength≥10 cN/dtex; (b) an elastic modulus≥200 cN/dtex; and (c) an elongation=3-9%, and a fiber (B) having a specific strength and elongation. The obtained intertwisted cord has a specific strength, elongation and elongation under 2.0 cN/dtex load.;COPYRIGHT: (C)2003,JPO
