CA 2676830

The invention relates to a high-strength, light non-woven of spunbonded non-woven as reinforcement material, comprising at least one layer of melt-spun synthetic filaments which are solidified by means of high energy water jets, and characterized in that it contains a thermally activatable binder which is applied onto the layer of melt-spun filaments in form of at least one thin layer. The invention also relates to a method for producing such a non-woven.

L'invention concerne un étoffe nappée légère, très résistante, composée de non-tissé, notamment destinée à être employée en tant que matériau de renforcement ou d'armature. L'étoffe nappée comporte au moins une couche de filaments synthétiques filés par fusion, consolidés au moyen de jets d'eau riches en énergie. L'étoffe nappée est caractérisée en ce qu'elle contient un liant thermoactivable, appliqué sous forme d'au moins une couche mince sur la couche de filaments filés par fusion. L'invention concerne également un procédé de fabrication d'une telle étoffe nappée.
