Characteristics of light-absorbing heat-emitting polyester fibers
The surface morphology,characteristic structure and functional groups,thermal properties,crystal structure,mechanical properties and light absorption properties of light-absorbing heat-emitting polyester fibers and ordinary polyester fibers were studied by means of scanning electron microscopy,Fourier infrared spectroscopy,differential scanning calorimetry,X-ray diffraction,fiber strength elongation test and UV-vision-near-infrared spectroscopy,and the performance difference between the two was analyzed. The results showed that the longitudinal morphology of two kinds of fibers was the same,but there were fine particles attached onto the surface of the light-absorbing heat-emitting polyester fibers. Compared with the ordinary polyester fibers,the crystallinity of light-absorbing heat-emitting polyester fibers decreased,the melting temperature,breaking strength and initial modulus were slightly lower,and the elongation at break was slightly higher. The light-absorbing heat-emitting polyester fibers had better absorbent ability in the full spectrum band.
