Abstract

PROCEDE DE PREPARATION DE FILAMENTS OU FIBRES HYDROPHILES POSSEDANT D'EXCELLENTES PROPRIETES TEXTILES PAR FILAGE AU MOUILLE DE POLYMERES OU COPOLYMERES DE L'ACRYLONITRILE DANS UN SOLVANT NON AQUEUX, PRECIPITATION DANS UN BAIN AQUEUX ET EVENTUELLEMENT ETIRAGE ET LAVAGE. ON AJOUTE A LA SOLUTION DE FILAGE, PAR RAPPORT AU POLYMERE, DE 10 A 100 , DE PREFERENCE DE 50 A 100 , D'UN COMPOSE ORGANIQUE LIQUIDE NON POLAIRE QUI EST SOLUBLE DANS LA SOLUTION DE FILAGE, INSOLUBLE DANS L'EAU ET LES SOLUTIONS AQUEUSES DU SOLVANT DE FILAGE, ET NE CONSTITUE PAS UN SOLVANT A L'EGARD DU POLYMERE. LE PROCEDE SELON L'INVENTION DONNE DES FIBRES A STRUCTURE POREUSE FINE ET REGULIERE ET QUI PRESENTENT PAR CONSEQUENT D'EXCELLENTES PROPRIETES MECANIQUES.PROCESS FOR PREPARING HYDROPHILIC FILAMENTS OR FIBERS POSSING EXCELLENT TEXTILE PROPERTIES BY WET SPINNING OF POLYMERS OR COPOLYMERS OF ACRYLONITRILE IN A NON-AQUEOUS SOLVENT, PRECIPITATION IN A WATER BASED BATH AND EVENTUALLY LAYING. A NON-POLAR LIQUID ORGANIC COMPOUND WHICH IS SOLUBLE IN THE SPINNING SOLUTION, INSOLUBLE IN WATER AND SOLUTIONS, IS ADDED TO THE SPINNING SOLUTION, WITH RESPECT TO THE POLYMER, FROM 10 TO 100, PREFERENCE FROM 50 TO 100. AQUEOUS SPINNING SOLVENT, AND DOES NOT CONSTITUTE A SOLVENT TO THE POLYMER. THE PROCESS ACCORDING TO THE INVENTION GIVES FIBERS WITH A FINE AND REGULAR POROUS STRUCTURE AND WHICH THEREFORE HAVE EXCELLENT MECHANICAL PROPERTIES.
