Abstract
L'INVENTION CONCERNE UNE FIBRE DE POLYMERE D'ACRYLONITRILE FILE A L'ETAT FONDU AYANT UNE INTENSITE RELATIVE DE TEINTURE ET UNE STABILITE AU TRAITEMENT AU MOUILLE A CHAUD AMELIOREES ET SON PROCEDE DE FABRICATION. SELON L'INVENTION, ON EXTRUDE A TRAVERS UNE FILIERE UNE MASSE FONDUE EN PHASE UNIQUE HOMOGENE D'EAU ET DE POLYMERE D'ACRYLONITRILE CONTENANT DES GROUPES HYDROPHILES, LA QUANTITE D'EAU DANS LADITE MASSE FONDUE ETANT DANS LA MOITIE INFERIEURE DE LA GAMME DES QUANTITES NECESSAIRES POUR DONNER UNE MASSE FONDUE A PHASE UNIQUE DANS LES CONDITIONS D'EXTRUSION ET LA QUANTITE DE GROUPES HYDROPHILES CONTENUS DANS LEDIT POLYMERE ETANT SUFFISANTE POUR REGLER LA VITESSE D'ELIMINATION DE L'EAU DU PRODUIT EXTRUDE NAISSANTEN CONJONCTION AVEC LE TRAITEMENT ET EVITER LA FORMATION NOTABLE D'UNE PHASE AQUEUSE SEPAREE; ON FAIT PASSER LEDIT PRODUIT EXTRUDE NAISSANT DIRECTEMENT DANS UNE ZONE DE SOLIDIFICATION SOUS PRESSION DE VAPEUR MAINTENUE DANS DES CONDITIONS DE SATURATION ET DE PRESSION POUR DONNER UN PRODUIT EXTRUDE NAISSANT SOLIDIFIE ET EVITER LA FORMATION NOTABLE D'UNE PHASE AQUEUSE SEPAREE DANS LE PRODUIT EXTRUDE SOLIDIFIE PENDANT L'ELIMINATION D'EAU DUDIT PRODUIT EXTRUDE; ON EVACUE LE PRODUIT EXTRUDE SOLIDIFIE DE LADITE ZONE DE SOLIDIFICATION SOUS PRESSION DE VAPEUR DANS L'ATMOSPHERE POUR DONNER UN PRODUIT EXTRUDE SOLIDIFIE CONTENANT DE L'EAU RESIDUELLE DANS UNE PHASE UNIQUE EAU-POLYMERE; ET ON SECHE LE PRODUIT EXTRUDE RESULTANT DANS DES CONDITIONS DE TEMPERATURE ET D'HUMIDITE APPROPRIEES POUR EN ELIMINER L'EAU ET EVITER LA FORMATION NOTABLE D'UNE PHASE AQUEUSE SEPAREE DANS LEDIT PRODUIT EXTRUDE.
