Study on Performances of Nano-Antibacterial PET Fiber

The IR spectrum, DSC spectra, physical-mechanism performances, far-infrared radiation, and antibacterial activity of nano-antibacterial PET fiber have been tested, and comparaed with common PET fiber. The results indicate that the nano-particles are equably distributed and there is no large reunite in fiber; the fundamental structure and heat performance of the fiber doesn′t change; compared with common PET fiber, the breaking tenacity of nano-antibacterial PET fiber decreases a little but the breaking extension has increased, the stress-strain curve becomes gradual. Nano-antibacterial PET fiber has excellent antibacterial activity.
