    • 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.
    • 本发明涉及一种具有至少三股绞合(T1,T2,T3)的织物帘线(50),所述三股绞合包括至少N股绞合线(20a,20b,20c,20d),其中N大于1, 到最终方向D2上的最终扭转T3,每根股线由M根预弯股(10a,10b,10c)组成,其中M大于1,所述预弯股依次扭转到中间扭转T2( T2a,T2b,T2c,T2d)在与D2相反的中间方向D1上移动,其中每个预绞线由已经在其自身上扭转到初始扭转T1(T1a,T1b,T1c)的纺织纤维(5) 在方向D1上,其中N倍M纺制纤维的至少一半具有大于800cN / tex的初始弹性模量Mi。 该织物帘线可以有利地用作车辆充气轮胎中的增强件,尤其是在所述充气轮胎的带或胎体帘布层中。
