Abstract
L'invention concerne un procédé de production de fibres filées en solution, présentant un moindre coefficient de frottement et d'autres propriétés améliorées, telles que la résistance à l'usure et analogues, comparativement aux fibres filées en solution conventionnelles. Selon le procédé de l'invention, du polytétrafluoroéthylène (PTFE) est incorporé dans la substance formant les fibres durant le processus de filage en solution, avant le passage à la filière. Le PTFE utilisé dans l'invention comprend de la poudre de PTFE dispersible en une faible granulométrie, de l'ordre du micron ou du sous-micron, et des dispersions aqueuses ou organiques d'une telle poudre de PTFE hautement dispersible. L'invention concerne également des tissus, des produits textiles et autres articles manufacturés fabriqués à partir de fibres filées en solution, améliorées au PTFE selon l'invention.
