Title (EN) CHITOSAN SUPERFINE FIBER SYSTEMS
(FR) SYSTÈMES DE FIBRE SUPERFINE DE CHITOSANE
Abstract:
(EN) The present chitosan-based superfine fiber invention relates to compositions, formulations, and processes that result in numerous significant advantages for the production and use of superfine fiber bioactive matrices in biomedical applications. The present invention relates to superfine, chitosan-based fibers, wherein the chitosan-based fibers have a percentage chitosan content of at least about 20% w/w, and highly conformable and compliant matrices comprising such fibers, processes for their production, and related formulations. The superfine chitosan-based fibers of the invention preferably include microfibers with diameter less than or equal to about 10 microns and micron and submicron fibers that are about 2 microns and less.
(FR) La présente invention concerne une fibre superfine à base de chitosane, qui a trait à des compositions, des formulations et des procédés qui procurent de nombreux avantages considérables permettant la production et l'utilisation de matrices bioactives à fibres superfines dans des applications biomédicales. La présente invention concerne des fibres à base de chitosane, superfines, les fibres à base de chitosane possédant une teneur en chitosane en pourcentage d'au moins environ 20 % en poids, et des matrices très adaptables et souples comprenant de telles fibres, leurs procédés de production et des formulations associées. Les fibres à base de chitosane superfines de l'invention comportent de préférence des microfibres d'un diamètre inférieur ou égal à environ 10 microns et des fibres microniques et submicroniques d'environ 2 microns et moins.
