    • The present invention relates to a functional fiber for preventing forgery, more particularly functional fiber for preventing forgery which exerts functionality by mixing special pigments to composite fibers of side by side shape on which two components are attached.The functional fibers of two components structure according to the present invention are consisted of synthetic high molecules, and have functionality which fibers display color by colored pigments with visual or fluorescence by light of ultraviolet ray or absorbing property of infrared pigments by being produced by mixing colored pigments, fluorescent pigments, infrared pigments and the like to each resin, and then melt-spinning the said mixture, or post treating it.While such fibers according to the present invention are hard to have a property of fibers since those contain pigments above a specific concentration, the fibers have functionality for preventing forgery by mixing a monofilament which is obtained by cutting the said fibers to papers, resins of high molecules, or coating agents so that it can be used as a functional element for preventing forgery and identifying authenticity of particular product demanded security such as a bank bill, a bond, a passport, an identity card.
    • 本发明涉及防止伪造的功能性纤维,更具体地说,涉及防止伪造的功能性纤维,其特征在于,通过将特殊颜料与并置有两种成分的复合纤维混合而发挥功能。 根据本发明的两种组分结构的功能性纤维由合成的高分子组成,并且具有通过紫外线光或视觉或荧光的颜色通过彩色颜料显示颜色的功能,或者通过混合着色的 颜料,荧光颜料,红外线颜料等,然后将所述混合物熔融纺丝或后处理。 虽然根据本发明的这种纤维难以具有纤维的性质,因为它们含有高于特定浓度的颜料,但是纤维具有通过将通过将所述纤维切割成纸而获得的单丝混合成纸,防止伪造的功能, 分子或涂层剂,使得其可以用作防止伪造和识别特定产品所需安全性的真实性的功能元件,例如银行票据,债券,护照,身份证。
