 Full text | Abstract: A method is presented for the preparation of collagen-modified chitosan fibres (Chit/Col) from chitosan-collagen solutions. The fibres may be used in the construction of scaffolds. Chitosan solutions with a concentration of 5.21% in an aqueous 3.0% acetic acid solution with the addition of glycerol were mixed with aqueous solutions of collagen. The applied chitosan was derived from the northern shrimps (Pandalus borealis) and the collagen from calf hide. The usability of chitosan and collagen was determined for the preparation of spinning solutions and Chit/Col fibres. Rheological properties are discussed for the chitosan-collagen solutions used in the spinning of Chit/Col fibres with linear density in the range of 3.30 – 8.36 dtex. The fibres are featured by increased nitrogen content and tenacity when compared to pure chitosan fibres. The performance of the spinning process was good. |
