Characterization The luminous spun-bonded nonwoven surface was determined using a SEM scanning electron microscope (HITACHI SU-1510, Japan). The excitation and emission spectra of luminous nonwoven were obtained at room temperature using a fluorescence spectrophotometer (HITACHI 650-60, Japan) with an emission wavelength of 520 nm and the excitation wavelength was 365 nm. The mechanics' properties of luminous nonwoven were examined and compared with untreated PP nonwoven using a YG026D type multifunctional electronic fabric strength tester at 20 ºC and 65% RH. The afterglow char acteristics of the samples were assessed using a PR-305 long afterglow phosphors tester. And the samples were exposed at an illumination intensity of 1000 lx for 15 min, and then the afterglow intensity was measured 10 s later. The phase composition of the luminous spun-bonded nonwoven and the luminescent materials were measured by X-ray diffraction (D8 Advance X-ray diffractormeter, Bruker AXS, Germany) by Cu Kα radiation at a voltage of 40 kV, and current of 30 mA. The range of diffraction angle 2θ is from 3° to 90° and the scan speed is 4 (°)/min at room temperature. DSC measurements were per- formed using DSC Q200 instruments (Waters, USA) under a flow of nitrogen at a rate of 50 mL/min to avoid oxidation. The samples of about 5 mg were weighed into the crucible and cover was hermetically sealed using the pierced lid. The samples undergone first heating up from 25 to 300 °C at 10 ºC/min, and each sample was heated to the melt at 200 ºC for 3 min to remove any prior thermal history. Subsequently, they were cooled down to 25 ºC with a scan rate of 10 ºC/min.
