Description

The focus of this present work is to develop a novel security paper sheet which includes Kapok fibers containing solid fluorescence particles inside. The Kapok fibers are natural half transparent hollow tubes whose inner and outer diameters are 18 and 20µm respectively. The fibers exhibit superior water repellent properties and absorb oil due to capillary force. Furthermore, the fibers have high hollow rate. In general, synthetic fibers have hollow rate of about 50%, however, those of Kapok fibers are over 80%. In this paper, we tried to make Kapok fibers containing solid fluorescence particles inside, and a paper sheet containing the composite fibers as described above. We found the paper sheet exhibits strong luminescent. The Kapok fibers including solid fluorescence particles have a beneficial effect on anti-counterfeit technologies.
