Cellulose filament yarn for industrial application having a breaking tenacity of higher than 600 mN/tex and containing more than 400 filaments, with a cord made of said yarn having a breaking tenacity of higher than 450 mN/tex at a twist factor of 200, and the filaments of which the yarn is built up having a morphology which does not vary pseudoperiodically along the axis of the filament. Preferably, the yarn contains more than 1000 filaments and has a breaking load of higher than 850 mN/tex. The yarn and the cord can be used as reinforcing material, e.g., as reinforcing material in hose or in rubber articles subject to a mechanical, dynamic load, such as vehicle tyres.

L'invention concerne un fil continu en cellulose pour des applications industrielles, ayant une ténacité supérieure à 600 mN/tex et contenant plus de 400 filaments, ainsi qu'une corde réalisée avec ce fil, ayant une ténacité supérieure à 450 mN/tex et un coefficient de tordage de 200. Les filaments servant à fabriquer ce fil ont une morphologie qui ne varie pas d'une manière pseudopériodique le long de leur axe. De préférence, le fil contient plus de 1000 filaments et il a un point de rupture supérieur à 850 mN/tex. Le fil et la corde peuvent être utilisés comme matériau de renforcement, par exemple comme matériau de renforcement dans des tuyaux ou dans des articles en caoutchouc soumis à des sollicitations mécaniques et dynamiques, tels que des pneumatiques de voitures.
