Preparation and characterization of Taichi masterbatch/polyester functional composite fiber

As a natural ore, Taichi stone brings potential market value and social value due to its health-care functions, such as releasing far-infrared and anti-ultraviolet (anti-UV) and anti-bacterial functions. In this study, Tachi masterbatch (containing 10% Tachi nanoparticles)/polyester (PET) functional composite fiber was prepared by electro-spinning. To study the effect of nanoparticle content on the composite fibers, five spinning solutions with different nanoparticle contents were mixed and electrospun. The spun fibers were then characterized by using scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and far-infrared and UV testing devices, respectively. The result shows that when the Taichi nanoparticle content is 3%, the composite fiber membranes will have a better dispersion, the fiber is more uniform, and smaller fiber diameter can be obtained. Compared with the pure PET fiber, the composite fibers have an improved far-infrared radiation performance and anti-UV performance. The highest nanoparticle content of 7% composite fiber gives the best far-infrared radiation and anti-UV performance. The newly developed Taichi masterbatch/PET functional composite fibers have potential application for the development of multi-functional textiles and apparels in the future.
