SHAPED CAPILLARY PRODUCTION OF HOMOFILAMENT CRIMP FIBERS

Robust homofilament fibers are meltspun from specially shaped capillaries to induce differential shear to induce crimping. Crimping may further be aided by directed quenching and drawing of the fibers. L'invention concerne des fibres homofilaments robustes qui sont filés par fusion à partir de...

Beschreibung
Zusammenfassung:	Robust homofilament fibers are meltspun from specially shaped capillaries to induce differential shear to induce crimping. Crimping may further be aided by directed quenching and drawing of the fibers. L'invention concerne des fibres homofilaments robustes qui sont filés par fusion à partir de capillaires spécialement façonnés afin de provoquer un cisaillement différentiel, et par la même le crêpage qui peut être suivi par une trempe de refroidissement dirigée et de l'étirage des fibres.
