Abstract

L'invention concerne une fibre monofilament tubulaire dotée de points faibles prédéfinis, destinée à un système de gazon artificiel. La fibre comprend un tube comprenant une paroi périmétrique enfermant une zone intérieure creuse du tube, et une pluralité de points faibles prédéfinis, formés dans la paroi périmétrique, qui divisent la paroi périmétrique en une pluralité de fibrilles et relient les fibrilles adjacentes. Les points faibles prédéfinis peuvent facilement être rompus pour déconnecter la pluralité de fibrilles les unes des autres par un moyen mécanique pour le brossage de la fibre, par des procédés classiques de brossage, utilisés lors de l'installation d'un gazon artificiel, ou par les traces de pied des joueurs. La zone intérieure creuse, la paroi périmétrique et la pluralité de points faibles s'étendent depuis une extrémité supérieure de la fibre jusqu'à une extrémité inférieure de la fibre.
