Abstract

L'invention se rapporte à des fibres creuses microporeuses asymétriques améliorées comportant un tensioactif de faible masse moléculaire et au procédé de production de ces fibres creuses. Les fibres creuses possédent des caractéristiques largement améliorées de flux et de réhumectage. Le processus consiste à faire passer une solution polymère par un anneau externe de la matrice afin de créer un courant annulaire ainsi qu'un fluide de précipitation par l'orifice interne de la matrice produisant un courant dans le courant annulaire entraînant la formation de fibres creuses. Le procédé consiste également à incorporer un tensioactif de faible masse moléculaire dans les fibres creuses à n'importe laquelle des différentes étapes du procédé.
