Title (EN) MODIFIED VISCOSE FIBRES AND METHOD FOR THEIR MANUFACTURE
(FR) FIBRES DE VISCOSE MODIFIEES ET PROCEDE DE FABRICATION DE TELLES FIBRES
Abstract:
(EN) The invention relates to a modified viscose fibres comprising viscose cellulose and containing in their structure microcrystalline chitosan forming after spinning mainly hydrogen bonds with the regenerated cellulose of viscose fibres. The microcrystalline chitosan contains chelated metal ions in order to modify and improve the properties of viscose fibres.
(FR) L'invention se rapporte à des fibres de viscose modifiées qui contiennent de la cellulose de viscose et qui comportent dans leur structure du chitosane microcristallin formant après filage essentiellement des liaisons d'hydrogène avec la cellulose régénérée des fibres de viscose. Le chitosane microcristallin contient des ions métalliques chélatés qui modifient et améliorent les propriétés des fibres de viscose.
