Abstract

FIBRES OU FILAMENTS HYDROPHILES PRESENTANT UNE STRUCTURE EN NOYAU-ENVELOPPE, FILES A SEC A PARTIR DE POLYMERES SYNTHETIQUES FIBROGENES HYDROPHOBES, CES FIBRES OU FILAMENTS PRESENTANT UNE POROSITE D'AU MOINS 50, UNE CAPACITE DE RETENTION DE L'HUMIDITE D'AU MOINS 100 ET UNE DENSITE AU MERCURE DE 0,7GCM AU MAXIMUM. ON AJOUTE A LA SOLUTION DE FILAGE UNE SUBSTANCE QUI PRESENTE UN POINT D'EBULLITION SUPERIEUR A CELUI DU SOLVANT DE FILAGE, EST BIEN MISCIBLE AVEC CE SOLVANT ET AVEC L'EAU ET CONSTITUE UN NON-SOLVANT A L'EGARD DU POLYMERE SOUMIS AU FILAGE, ET ON INJECTE DANS LE PUITS DE FILAGE QUI EST A UNE TEMPERATURE MAXIMALE DE 140C DE LA VAPEUR D'EAU OU DE LA VAPEUR D'UN AUTRE LIQUIDE COAGULANT LES FILAMENTS, ETANT SPECIFIE QUE LES PROPORTIONS RELATIVES EN POIDS ENTRE LA MATIERE SOLIDE POLYMERE ET LE NON-SOLVANT EST DE 2:1 ENVIRON AU MAXIMUM. LES FIBRES OU FILAMENTS SELON L'INVENTION EXTREMEMENT HYDROPHILES ET LEGERS, ONT DES APPLICATIONS NOMBREUSES EN PARTICULIER EN HYGIENE ET DANS L'HABILLEMENT.
