Par un procédé de filage par fusion de fibres conjuguées utilisant le polyéthylène téréphtalate comme composant central et le polyéthylène comme composant de gaine, un fil multifilament dans lequel des fibres longues conjuguées cœur-gaine ayant un rapport de masse entre le composant central et le composant de gaine de 1 à 4:1 sont collectées est obtenu. Un produit textile est obtenu par tissage, tricotage, tressage ou enroulement utilisant le fil multifilament. Le thermoformage de ce produit textile est effectué en chauffant le produit textile pour faire fondre le polyéthylène et simultanément pour lier par fusion les fibres longues conjuguées cœur-gaine les unes aux autres, le polyéthylène téréphtalate conservant sa forme de fibre initiale.
