/ MANUFACTURING METHOD FOR CHITIN NANOFIBER HAVING SURFACE MODIFIED WITH CHITOSAN THE CHITIN NANOFIBER HAVING SURFACE MODIFIED WITH CHITOSAN MADE THEREFROM CHITIN-COLLAGEN NANOFIBER MADE THEREFROM AND WOUND DRESSING MATERIALS USING THIS
The present invention relates to a preparation method for chitosan surface-modified chitin nanofibers, in which high-purity chitin is produced by the decalcification and deproteinization of squid cartilages or crab shells, the high-purity chitin is surface-modified with chitosan, and the chitosan surface-modified chitin nanofibers are produced from the chitosan surface-modified chitin； to the chitosan surface-modified chitin nanofibers produced therefrom； to a chitin/collagen nanofiber fabric in which chitin nanofibers are produced from a dispersion solution obtained by mixing and dispersing the chitosan surface-modified chitin nanofibers and collagen produced from fish scales, fish skins, and fish placenta, and the chitin nanofibers are prepared as a fabric by spinning the same； and to a bio-absorbable chitin/collagen nanofiber fabric wound dressing material produced by laminating the chitin/collagen nanofiber fabric onto an adhesive sheet.본 발명은 오징어 연골 또는 게 껍질을 이용하여 탈칼슘 처리, 탈단백을 거쳐 고순도 키틴을 제조하고, 상기 고순도 키틴의 표면을 키토산화한 후, 표면 키토산화 키틴으로부터 제조되는 표면 키토산화 키틴 나노화이버의 제조방법과, 이로부터 제조되는 표면 키토산화 키틴 나노화이버와, 상기 표면 키토산화 키틴 나노화이버와, 생선비늘, 껍질, 어태반으로부터 제조된 콜라겐을 혼합하여 분산시킨 분산용액으로부터 키틴 나노화이버를 제조하고, 상기 키틴 나노화이버를 방사하여 원단으로 제조된 키틴/콜라겐 나노화이버 원단과,상기 키틴/콜라겐 나노화이버 원단을 점착시트에 합지시켜 제조된 생체 흡수성 키틴/콜라겐 나노화이버 원단 창상피복재에 관한 것이다.
