Study on Perfomances of Nano-Far-Infrared PET Fibers

The IR spectrum,DSC spectra,physical-mechanism performances,far-infrared radiation,heat retaining power,and antibacterial activity of nano-far-infared 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 fibers;the fundamental structure and heat performance of the fiber doesn't change;compared with common PET fiber,both the breaking tenacity and breaking extension of nano-far-infared PET fiber decrease a little.Nano-far-infared PET fiber had excellent far-infrared radiation power,heat retaining power and antibacterial activity.
