The focus of this present work is to develop a novel paper sheet which includes Kapok fibers containing Solid fluorescence particles inside. The Kapok fiber is natural half-transparent hollow tube whose inner and outer diameters are 18 and 20 μm respectively. This fibers exhibit superior water repellent properties and absorb oil due to capillary force. Furthermore, the fibers have a high hollow rate. In general, synthetic fibers have a hollow rate of under 50%, however, those of Kapok fibers are about 90%. In this paper, we made Kapok fibers containing Solid fluorescence particles inside, and a paper sheet containing the composite fibers as described above. We found that the paper sheet exhibits strong luminescent and high solvent resistance. The Kapok fibers including Solid fluorescence particles have a beneficial effect on anti-counterfeit technologies.
