Abstract

L'invention porte sur une fibre pour gazon artificiel du type des fibres monofilaments utilisées dans la fabrication de moquettes pour gazon artificiel et qui sont obtenues par extrusion à partir de polyoléfines, de polyéthylène ou d'une autre matière, la fibre (1) formant les moquettes pour gazon artificiel présentant une section transversale de forme générale plate rectangulaire à petits côtés arrondis, dans la partie centrale de l'une des grandes faces de laquelle est prévue une saillie convexe incurvée (2) tandis que, dans l'autre grande face, est prévue une paire de saillies convexes incurvées (3) placées dans des positions symétriques par rapport à son axe central, au moyen desquelles on obtient une fibre pour gazon artificiel possédant une haute résilience qui facilite sa récupération vis-à-vis de charges occasionnelles ou temporaires successives, lui conservant ainsi son apparence d'origine pendant plus longtemps.
