Title
(EN) FINE FIBERS MADE FROM ROOM TEMPERATURE CROSSLINKING
(FR) FIBRES FINES OBTENUES À PARTIR D'UNE RÉTICULATION À TEMPÉRATURE AMBIANTE
Abstract
(EN)
The present disclosure provides a unique method of making a fine fiber that is formed from a composition including an epoxy and a polymer component including a 4-vinyl pyridine- containing polymer. The present disclosure also provides a unique method of coating a fine fiber with a composition including an epoxy and a polymer component including a 4-vinyl pyridine- containing polymer. The present disclosure further provides fine fibers wherein the entirety of the fiber is formed from a composition including an epoxy and a polymer component including a 4-vinyl pyridine-containing polymer. Also provided are filter media and filter substrates including the fine fibers.
(FR)
La présente invention concerne un procédé unique de fabrication d'une fibre fine qui est formée à partir d'une composition comprenant un époxy et un constituant polymère comprenant un polymère contenant de la 4-vinylpyridine. La présente invention concerne également un procédé unique de revêtement d'une fibre fine avec une composition comprenant un époxy et un constituant polymère comprenant un polymère contenant de la 4-vinylpyridine. La présente invention concerne en outre des fibres fines, la fibre entière étant formée à partir d'une composition comprenant un époxy et un constituant polymère comprenant un polymère contenant de la 4-vinylpyridine. L'invention concerne également un milieu filtrant et des substrats filtrants comprenant les fibres fines.
