    • 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 μm 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. The invention also relates to a silk tow that contains 2 to 50 primary fibres. Moreover, the invention relates to the use of the fibres for the production of woven and non- swoven fabrics.
    • 本发明涉及透明质酸类纤维的制备方法,其中首先制备透明质酸和/或其金属化合物的纺丝溶液,任选地含有金属盐或透明质酸化合物和金属离子,然后 将纺丝溶液引入包含酸,醇的不超过10重量%的凝固浴中。 的水和任选的金属盐,导致形成优选留在凝固浴中和/或拉伸的纤维,然后用醇洗涤纤维并干燥。 洗涤纤维后,可以通过金属化浴将金属离子引入纤维中。 此外,本发明涉及基于透明质酸和/或其金属化合物的纤维,其纤维(单丝)直径为4μm至1mm,线形重量为0.1至30g / 1000m(0.1至30tex),拉伸强度 强度为0.5〜3cN.dtex-1,回弹强度为拉伸强度的20〜80%。 本发明还涉及含有2至50个初级纤维的丝束。 而且,本发明涉及纤维用于生产机织和非织造织物的用途。
