description | Un método de preparación de fibras basado en un derivado de hialuronano C11-C18 acilado en los grupos hidroxi del ácido hialurónico caracterizado por que se prepara una solución de hilatura que comprende un derivado acilado de hialuronano de la concentración en el intervalo de 0,01% en peso a 15% en peso en una mezcla de agua y 2-propanol, donde el contenido de agua está en un intervalo de 30% en volumen a 90% en volumen, el contenido de 2-propanol de 10% en volumen a 70 % en volumen, después la solución de hilatura se introduce en el baño de coagulación que comprende una solución acuosa de un ácido orgánico o sus sales de metales alcalinos o metales alcalinotérreos, en donde el ácido se selecciona del grupo que comprende el ácido láctico, tartárico, cítrico, málico, ascórbico, oxálico o una combinación de los mismos, para forman fibras que luego se lavan con alcohol y se secan.
The invention relates to the biodegradable fibres which are based on hydrophobic derivatives of hylauronan, specifically on the base of the hyaluronan derivative C11-C18-acylated on hydroxyl groups of hyaluronic acid, and use thereof. Further the invention relates to the preparation of these fibres which is performed with the use of the wet spinning method in a coagulation bath comprising water solution of organic acid, with the production of continuous monofiles which can be thereafter processed to threads and further to textiles, knitted textiles, or nonwoven textiles. These textiles, knitted textiles or nonwoven textiles can be used for example for the production of implantable surgical material for human and veterinary medicine. |
