Title
(EN) Modified viscose fibres and method for their manufacture
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.
