Title (EN) PRODUCTION OF NON-WOVEN MATERIALS FROM POLYHYDROXYALKANOATE
(FR) PRODUCTION DE MATÉRIAUX NON TISSÉS À PARTIR DE POLYHYDROXYALCANOATE
Abstract:
(EN) Methods and compositions for making non-woven materials from polyhydroxyalkanoate polymers are provided. In certain aspects, the invention pertains to an extruded fiber comprising a polyhydroxyalkanoate polymer, a wet milled nucleating agent and a plasticizer, wherein the average particle size of the wet-milled nucleating agent is about 20 microns and is dispersed in the polymer.
(FR) La présente invention concerne des procédés et des compositions destinés à la fabrication de matériaux non tissés à partir de polymères de polyhydroxyalcanoate. Sous certains aspects, l'invention concerne une fibre extrudée comprenant un polymère de polyhydroxyalcanoate, un agent de nucléation broyé humide et un plastifiant, la taille moyenne des particules de l'agent de nucléation étant d'environ 20 µm, et ces particules étant dispersées dans le polymère.
