In this study, we investigate the fabrication of far-infrared polyester chips. At first, we research the composition of the milling solution. The result shows the average sizes of far-infrared particles are 400 nm and disperse very well. Furthermore, in order to improve the compatibility of far-infrared particles in polyester, we adjust the quantity of dispersant, which was used to disperse far-infrared particles into the polyester matrix. Consequently, we can produce far-infrared chips which have excellent heat generation ability (raising-temperature (The symbol is abbreviated) 5.5℃, heat generation temperature (The symbol is abbreviated) 4.5℃).
