Embodiment 1

[0020] Example 1: see figure 1 , figure 1 Two black infrared fibers 2 and two black magnetic fibers 3 are mixed on the middle anti-counterfeiting paper 1, and the shapes and lengths are similar. Black infrared fiber refers to the chemical fiber that transmits in the near-infrared band of 700-1100nm, is non-magnetic and can be combined with paper; black magnetic fiber refers to the chemical fiber that absorbs in the near-infrared band of 700-1100nm and has magnetic characteristics. Chemical fibers that can be combined with paper. Under the infrared detector (manufactured by Yunnan Zhihai Optoelectronics Technology Co., Ltd.), the black magnetic fiber 3 can be observed, while the black infrared fiber 2 disappears. The magnetic signal of the magnetic fiber 3 can be detected by a magnetic reader.

Embodiment 2

[0021] Example 2: see figure 2 , figure 2 In addition to being mixed with two black infrared fibers 2 and two black magnetic fibers 3, the middle anti-counterfeiting paper 1 is also printed with number 4, barcode 5 and serial number 6 information uniquely corresponding to the characteristics of the two fibers, forming comprehensive information. In the process of making the anti-counterfeit paper, the above-mentioned comprehensive information can be set as an anti-counterfeit information database and stored in the inspection device, so that the anti-counterfeiting of digital information can be realized, and the anti-counterfeiting effect can be further improved. The specific identification process is as follows: use infrared fiber and magnetic fiber sensors to read out the corresponding magnetic information and infrared information; correspond to the printed number to form associated information, and compare the unique features in the inspection device according to the unique...

Embodiment 3

[0022] Embodiment 3: the manufacture method of embodiment 1 fiber anti-counterfeiting paper, comprises the following steps: 1), utilize known methods such as dyeing method, wet spinning, dry spinning, black infrared through material (for example trichromatic pigment The mixture) is combined in the chemical fiber to prepare black infrared fiber, and its near-infrared region passes through: 2), using known methods such as dyeing, wet spinning, dry spinning, etc., black magnetic materials (such as oxidized Iron black) is combined in the chemical fiber, prepares the magnetic fiber identical with described infrared fiber outward appearance color, and it has magnetism, and near-infrared region absorbs; 3) in the process of producing safety paper, join in paper in the same proportion A paper with infrared fibers and magnetic fibers doped with similar hues is formed.

Abstract

The invention is fiber anti-false paper and the manufacturing method, it refers to anti-false paper which has fiber anti-false character and the producingm ethod. The character lies in that there are infrared fibver and magnetism fiber on the anti-false paper. The method is: the two fibers are put into the paper according to proper proportion, forms approximate color paper. It uses the infrared fiber and magnetism fiber sensor to test the signal of the two fibers, and it carries the data information into testing equipment, it is tested with data information of number, bar code or flow number in sensor, so it can realize information anti-false.

Description

Technical field: [0001] The invention relates to an anti-counterfeit paper, in particular to an anti-counterfeit paper with fiber anti-counterfeit features and a method for making the anti-counterfeit paper. Background technique: [0002] The use of anti-counterfeiting fibers on security paper such as securities is an effective anti-counterfeiting feature and means. It has been used for many years and has been widely used in banknotes, passports, trademarks and various securities. Usually, the types of anti-counterfeiting fibers include colored fibers, fluorescent fibers, metal fibers, infrared fibers, magnetic fibers, etc. Some belong to first-line anti-counterfeiting, and some belong to expert anti-counterfeiting. Magnetic fiber anti-counterfeiting can be used for machine-readable anti-counterfeiting due to its magnetic characteristics. However, because copies or counterfeit products are relatively easy to have magnetic characteristics, they are easy to be confused with ge...
