Abstract

L'invention concerne une fibre hydrophobe qui, obtenue par modification d'un matériau fibreux contenant des fibres naturelles sans avoir recours à des composés fluorés, présente une amélioration des propriétés de séchage rapide, de durabilité, des propriétés de tissu infroissable et non salissant tout en conservant suffisamment l'absorption et la désorption d'humidité des fibres naturelles. L'invention concerne également un procédé de fabrication de ladite fibre. En fixant un film élastomère de silicone sur au moins une partie de la surface d'un matériau fibreux qui contient des fibres de cellulose et/ou des fibres animales, la fibre est transformée en une fibre hydrophobe ayant une tension superficielle inférieure à 72 mN/m. Le film élastomère de silicone comprend du méthylhydrogénopolysiloxane réticulé avec du stéarate de zinc en tant qu'agent de réticulation.
