Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2021 / V.33,no.3,Sept Title Manufacturing and Material Analysis of Collagen/Chitosan Conjugated Fibers for Medical Application Authors Hyeon Jung Gwak1,2, Hyunchul Ahn1, Won Jun Lee2, and Sang Young Yeo1 Institution/Affiliations 1Korea Institute of Industrial Technology, 2Dankook University Pages/Total page pp.131 ~ 140 / 10 Language Korean Abstract Collagen and chitosan are used in medical and cosmetic materials as natural polymers. In order to utilize the advantages of the materials, collagen/chitosan conjugated wet-spun fibers were prepared. The analysis of surface, optical, thermal and mechanical properties was carried out on the various composition of collagen and chitosan. As a result of images analysis, it was verified that the collagen/chitosan conjugated fibers were stably spun. In addition, the optical and thermal properties of fibers were observed to be changed by hydrogen bond. As a result, an optimized composition could be found at an appropriate content. Moreover, the optimized fibers have mechanical properties similar to chitosan fibers, while improving the structural and thermal stability by its hydrogen bond. In addition, the wet-spun collagen/chitosan conjugated fibers can be applied to medical and various fields through mechanical properties according to content control.
