摘要：
A core material of a string for instruments comprises a twist of at least two multifilaments composed of a vinylidene fluoride resin, which simultaneously possesses the following properties (a) to (e):
(a) a diameter of 0.1 to 5 mm; (b) an elongation of 10 to 50 %; (c) a tensile strength of not less than 30 kg/mm²; (d) a creep elongation of not more than 15% (measured 24 hours after a load under which the stress of 20% of the tensile strength is applied to the twist); and (e) a Young's modulus of not less than 200 kg/mm².
