Title (EN) PROCESS OF MAKING CELLULOSIC FIBERS INCLUDING PTFE
(FR) PROCEDE DE FABRICATION DE FIBRES CELLULOSIQUES RENFERMANT DU PTFE
Abstract: front page image
(EN)The present invention is directed to a method for making solution spun fibers having decreased coefficient of friction and other improved properties such as wear resistance and the like, when compared to conventional solution spun fibers. In the method of the present invention, polytetrafluoroethylene (PTFE) is incorporated into the fiber-forming substance during the solution spinning process before passing through the spinneret. PTFE that is useful in the present invention includes PTFE powder that is dispersible to low micron or submicron particle size and aqueous or organic dispersions of such highly dispersible PTFE powder. The present invention is also directed to fabrics, textiles, and other articles of manufacture formed from the PTFE-enhanced solution spun fibers of the present invention.
(FR)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.
