Abstract

La présente invention concerne une surface textile comprenant au moins un fil en fibres coupées de fibres coupées, les fibres coupées comprenant au moins trois types de fibres coupées, un premier type de fibres coupées étant constitué de m fibres coupées d'aramide, un deuxième type de fibres coupées étant constitué de p fibres coupées d'aramide et un troisième type de fibres coupées étant constitué de fibres coupées de polyamide aliphatique. La surface textile est caractérisée en ce que ladite surface textile contient 30 à 45% p/p du premier type de fibres coupées, 45 à 55% p/p du deuxième type de fibres coupées et 10 à 20% p/p du troisième type de fibres coupées, rapporté au poids de la surface textile, ladite surface textile comprenant un premier fil en fibres coupées et un deuxième fil en fibres coupées et le premier fil en fibres coupées étant constitué de premier et de troisième types de fibres coupées et le deuxième fil en fibres coupées étant constitué de deuxième type de fibres coupées. La surface textile selon l'invention combine une haute résistance à l'abrasion avec un faible boulochage et présente en outre des valeurs élevées de la résistance au déchirement, à l'allongement à la rupture et à la propagation de déchirement.
