Patent

CA 2703958

A method of fiber formation by electrical-mechanical spinning is disclosed. A liquid starting material is fed to a rotating annular member such as a spinning cup. The liquid material is directed by centrifugal force to the periphery of the annular member where it is expelled in fibrous form. An electric charge is imposed on the liquid while on the annular member or while immediately being expelled from the annular member.

L'invention concerne un procédé de fabrication de fibre par filage électromécanique. Un élément annulaire rotatif, tel qu'une coupelle de filage, est alimenté en un matériau de départ liquide. Le matériau liquide est dirigé par la force centrifuge vers la périphérie de l'élément annulaire d'où il est expulsé sous forme de fibre. Une charge électrique est imposée sur le liquide pendant qu'il est sur l'élément annulaire ou pendant qu'il est en train d'être expulsé de l'élément annulaire.
