Abstract (en)
[origin: WO2016091809A1] The invention relates to a textile cord (50) having an at least triple twist (T1, T2, T3), comprising at least N strands (20a, 20b, 20c, 20d), where N is greater than 1, which are twisted together to a final twist T3 in a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), where M is greater than 1, which pre-strands are in turn twisted to an intermediate twist T2 (T2a, T2b, T2c, T2d) in an intermediate direction D1 which is opposite to D2, with every pre-strand consisting of a spun fibre (5) that has been twisted on itself to an initial twist T1 (T1a, T1b, T1c) in the direction D1, wherein at least half the N times M spun fibres have an initial modulus of elasticity Mi greater than 800 cN/tex. This textile cord can advantageously be used as reinforcement in vehicle pneumatic tires, especially in the belt or the carcass ply of said pneumatic tires.
