Abstract: The invention relates to the method of the preparation of polysaccharide fibers based on hyaluronic acid, a compound comprising hyaluronic acid and metal ions, schizophylan, chitin/chitosan-glucan complex, a compound comprising chitin/chitosan-glucan complex and metal ions, internal mixture of chitin and chitosan, a compound comprising internal mixture of chitin and metal ions, sodium alginate, potassium alginate, ammonium alginate, xanthane, xanthane sodium salt, xanthane potassium salt, oxycellulose, oxycellulose sodium salt, oxycellulose potassium salt, carboxymethyl cellulose, carboxymethyl cellulose sodium salt, and carboxymethyl cellulose potassium salt, or a mixture of polysaccharides, in a non-stationary coagulation bath. Further the invention relates to covers of internal and external wounds and skin defects based on these fibers, and a method of production thereof, and the apparatus for the preparation of polysaccharide fibers.

Abstract: The invention relates to the method of preparation of hyaluronic acid-based fibres, where first the spinning solution of hyaluronic acid and/or a metal compound thereof, optionally containing a metal salt or a hyaluronic acid compound and metal ions, is prepared, then the spinning solution is introduced into the coagulation bath comprising an acid, an alcohol and not more than 10% wt. of water, and optionally a metal salt, resulting in forming a fibre which is preferably left in the coagulation bath and/or is drawn, then the fibre is washed with alcohol and dried. After washing of the fibre, metal ions may be introduced in the fibre by means of the metalization bath. Further, the invention relates to the fibres based on hyaluronic acid and/or a metal compound thereof, having the fibre (monofilament) diameter 4 ?m to 1 mm, linear weight 0.1 to 30 g/1000 m (0.1 to 30 tex), tensile strength 0.5 to 3 cN·dtex?1 and loop strength 20 to 80% of the tensile strength.
