This project aims to provide a solution for spinning process of chitosan and its blends, which meet antibacterial requirement. The key of this study is the application of static theories on blending technology, and antistatic in chitosan spinning process. Besides, 100% chitosan yarns with sufficient length, strength, evenness and hairiness will be produced, which was never realized before the research. Also, an instruction will be given to manufacturers indicating properties of chitosan yarns with full-range blending ratios, so that they will be able to choose proper blending ratio, balancing performance and cost.
