The present invention relates to a fiber coated with a water blocking material that includes an essentially water free dispersion comprising a superabsorbent polymer and a dispersing medium. The fibers made according to this invention may be used, for example, as fiber reinforcing material used in the manufacture of cables, and in particular in yarns for fiber optical cables that use optical light wave guides for optical communication transmissions.
L'invention concerne une fibre revêtue de matériau imperméable comprenant une dispersion essentiellement dépourvue d'eau à base de polymère ultra-absorbant et de produit dispersant. Une fibre ainsi revêtue peut être utilisée, entre autres, comme matériau de renforcement dans la fabrication des câbles, et en particulier dans les fils destinés aux câbles à fibres optiques utilisant des guides d'ondes optiques pour les transmissions optiques.
