Abstract

Le problème abordé par la présente invention est de fournir : un tissu hydrofuge qui présente non seulement des propriétés hydrofuges mais présente en outre des propriétés d'étirement supérieures ; et un produit textile obtenu au moyen du tissu hydrofuge. Le moyen de résolution du problème est un tissu hydrofuge obtenu par conduite d'un traitement hydrofuge, le tissu étant amené à comprendre un fil composite qui comprend des fibres étirables et des fibres ultrafines ayant une finesse monofibre de 1 dtex ou moins.
