Abstract

Kapok fiber is natural half-transparent hollow tube whose inner and outer diameters are 18 and 20 mm, respectively. This fiber excels in water repellence and absorbs oil due to the capillary force. In addition, the hollow rate of this fiber is higher than those of conventional synthetic fibers. The focus of this present work is to develop a novel paper sheet which integrating Kapok fibers containing chromic materials. The solvent which contains chromic materials was absorbed into Kapok fibers due to the capillary force. We found that the paper sheet exhibits reversible color change.

使用含铬材料木棉纤维的防伪纸

木棉纤维为天然半透明中空管，内径18毫米，外径20毫米。由于毛细力，这种纤维具有优异的拒水性和吸油性。此外，该纤维的中空率高于常规合成纤维。本文的工作重点是研制一种将木棉纤维与含铬材料相结合的新型纸张。由于毛细力的作用，含铬物质的溶剂被木棉纤维吸收。我们发现纸张的颜色变化是可逆的。
