Abstract
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.
