    c) tirer ce fil bouclé à deux composants primaire sous tension de manière à stabiliser mécaniquement ledit filé primaire avec réduction de la taille des boucles ;
    d) chauffer le filé primaire stabilisé afin de fixer la structure du fil ; et
    e) le titre total des écheveaux de mèche, la différence des vitesses d'alimentation des écheveaux de mèche, les conditions du tourbillonnement, de la stabilisation mécanique et du fixage étant choisis de manière à obtenir un fil bouclé à deux composants dont la teneur en filaments fantaisie est de 25 % en poids au moins.
  13. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que l'on utilise comme écheveau de mèche pour le composant fantaisie un fil FOY qui a été filé à une vitesse de tirage supérieure à 2000 m/min en passant par les étapes de procédé suivantes :
    f) des multifilaments sont filés à chaud dans un dispositif de filage en soi usuel dans lequel un élément chauffant se trouve entre les buses de filage et l'élément de tirage ;
    g) les multifilaments filés sont refroidis à la température de solidification ou à une température inférieure en amont de l'élément chauffant ; et
    h) les multifilaments sont ensuite portés à des températures supérieures au point de solidification avec application simultanée d'une force de tirage du fil créée par le frottement sur le milieu gazeux environnant et qui peut être égale à la tension d'étirage nécessaire.
  14. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que l'on introduit dans la buse de texturation deux écheveaux de mèches se déplaçant à des vitesses différentes.
  15. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que les écheveaux de mèches présentent des titres totaux et en filaments isolés différents et en ce que la mèche pour le filament fixe se compose de filaments présentant une force de traction maximale, ramenée au titre final, au moins égale à 60 cN/tex, un retrait à chaud à 200 °C de 4 à 9 % et un allongement maximal à la traction de 8 à 15 %.
  16. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que l'écheveau de mèche introduit dans la buse de texturation pour préparer le fil fixe peut être obtenu directement, avant introduction dans la buse de texturation, par étirage d'un filé partiellement orienté immédiatement suivi d'un traitement thermique essentiellement exempt de retrait.
  17. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 15, caractérisé en ce que l'étirage de l'écheveau de mèche destiné à préparer le fil fixe se fait à une température de 70 à 100 °C et avec une tension d'étirage de 10 à 30 cN/tex, ramenée au titre étiré.
  18. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 16, caractérisé en ce que le traitement thermique essentiellement exempt de retrait immédiatement consécutif à l'étirage se fait à une température de 180 à 250 °C.
  19. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que le tirage du fil bouclé à deux composants primaire après l'opération de tourbillonnement se fait sous une tension de 0,05 à 1,0 cN/tex.
  20. Procédé de fabrication d'un fil bouclé à deux composants selon la revendication 12, caractérisé en ce que le fixage se fait selon un procédé comprenant les mesures suivantes :
    j) préchauffage d'un gaz de transfert thermique à une température supérieure à la température souhaitée pour le fil ; et
    k) acheminement du gaz de transfert thermique préchauffé vers un canal guide-fil de telle sorte que ledit gaz s'écoule sensiblement verticalement sur le fil passant dans le canal guide-fil sur une longueur telle que le fil est chauffé à la température supérieure souhaitée dans le dispositif de chauffage, la longueur de la zone de soufflage étant choisie de manière à ce que le fil soit en contact direct avec le gaz de transfert thermique du fait de l'enlèvement continuel de la couche limite par l'écoulement dudit gaz, permettant ainsi un échauffement rapide du fil.
  21. Utilisation des fils bouclés à deux composants composés de filaments fixes et de filaments fantaisie selon la revendication 1 comme fils à coudre et/ou comme fils à broder.
