| Summary: | This study aims to transform post-consumer textile waste (cellulosic materials) into viscose fiber using a xanthation technique, as well as to develop value-added antibacterial chitosan functionalized viscose (CFV) fiber for biomedical applications (e.g., sanitary pad) through an economic up-cycling wet spinning integrated chitosan coating approach. Surface morphology (SEM), FTIR, XRD, mechanical, thermal, and antibacterial properties (both gram-positive and gram-negative bacteria) were investigated for the CFV fiber. The Degree of Polymerization (DP) of the raw viscose (RV) fiber was approximately 782 ± 35, comparable to the DP of commercial viscose fibers. The surface of CFV fiber is uneven, hazy, and rough, and its average fiber diameter is 15.65 ± 1.75 μm, which is higher than commercial viscose fiber. CFV fibers have stronger strength than RV fibers, as demonstrated by FTIR, the creation of hydrogen bonds with chitosan is the fundamental reason for the strength.. Overall, antibacterial effects (zone of inhibition) against E. c oli, S.Typhi, and S.aureus are 17 ± 1.2 mm, 13 ± 0.8 mm, and 10 ± 1.1 mm, respectively. However, the development process and results confirm the successful formation of CFV fiber and highlight its potential for sustainable biomedical applications compared to other alternatives. |
