Problems solved by technology

At the same time, for the security thread made of polymer material, if it is embedded in the paper, it will block the hydrogen bonding of the fibers in the paper. As the line width increases, this blocking effect will become more obvious, resulting in a decrease in the bond fastness of the thread to paper. bad question
With the improvement of security thread application technology, paper with wide security thread with a width greater than 3mm has appeared. However, during the application of wide security thread, problems such as uneven paper surface and partial exposed lines will also occur due to the above reasons.
[0004] Anti-counterfeiting staple fiber is also one of the important anti-counterfeiting measures widely used in banknote paper and securities in various countries. The conventional adding method is to add anti-counterfeiting staple fiber into the pulp by mixing in the pulp, and then make the fiber random during the papermaking process. Distributed in different areas and layers of paper, so it cannot be detected by instruments

Embodiment 1

[0101] This embodiment provides a kind of anti-counterfeiting paper, which mainly includes the following steps:

[0102] 1. Prepare anti-counterfeiting long fibers: immerse the adhesive filament (white) spindle in a carbon tetrachloride solution that is dissolved with quantum dot materials, and the concentration of quantum dot materials in the solution is 1-200ppm (preferably 2-100ppm), Prepared adhesive filaments loaded with quantum dots, which emit green light when excited by ultraviolet light with a wavelength of 417nm;

[0103] 2. Warp the above-mentioned anti-counterfeit long fibers and the adhesive long fibers without quantum dot material treatment through a warping machine;

[0104] 3. Wefting hot-melt fiber filaments with a hot-melt temperature of 80°C;

[0105] 4. Use a narrow-width loom to obtain a webbing (i.e., an anti-counterfeit safety belt) through a weaving process. The width of the webbing is 10 mm. The side warp of the webbing is an adhesive filament with qu...

Embodiment 2

[0110] This embodiment provides a kind of anti-counterfeiting paper, which mainly includes the following steps:

[0111] 1. Use polyester filaments to warp, weft and weave to obtain ribbons. The width of the ribbon is 4mm. The weaving density of the ribbon is: warp density 60 / cm, weft density 60 / cm;

[0112] 2. Mix red fluorescent powder into the red ink, the particle size of the fluorescent powder is 100 μm, and the added amount accounts for 10% of the weight of the red ink to obtain a red fluorescent ink, which appears red under 365nm ultraviolet excitation light;

[0113] Mix the blue heat-sensitive material into the white ink, the particle size of the blue heat-sensitive material powder is 80 μm, and the added amount accounts for 5% of the weight of the white ink to obtain the blue temperature-changing ink;

[0114] 3. The above two kinds of inks are printed on the webbing as stems and branches of snowflakes by screen printing to obtain anti-counterfeit safety belts;

Embodiment 3

[0120] Example 3 anti-counterfeiting paper

[0121] The present embodiment provides a kind of anti-counterfeit paper, and it is applied with the webbing (anti-counterfeit safety belt) that embodiment 1 prepares, and it obtains through the following steps:

[0122] According to the conventional papermaking process, two cylinders are used for papermaking. During the papermaking process, the webbing is compounded into the wet paper sheet, and then through the subsequent papermaking steps, the anti-counterfeiting paper with the anti-counterfeiting safety belt is prepared;

[0123] Among them, the release of the webbing is as follows: Figure 7 Shown:

[0124] First, the cylinder wire 3 forms a wet paper sheet 5 and is transferred to the fourdrinier wire 4 by contacting with the fourdrinier wire 4;

[0125] Then, the ribbon 1 enters the slurry liquid 9 driven by another cylinder 3 (cage 2), and then contacts the cylinder 3, and forms another layer of wet paper with an anti-counte...

Abstract

The invention relates to an anti-counterfeiting safety belt and an anti-counterfeiting paper applied to the anti-counterfeiting safety belt. An anti-counterfeiting safety belt, which is a belt-shaped fabric with anti-counterfeiting information in at least part of the area, wherein the anti-counterfeiting information is formed by anti-counterfeiting materials, and the anti-counterfeiting materials include photoluminescent materials, magnetic materials, pressure-sensitive materials and bio-anti-counterfeiting materials; preferably, the photoluminescent material includes a combination of one or more of quantum dot materials, fluorescent materials, temperature-changing materials and infrared materials, the Biological anti-counterfeiting materials include antigens, antibodies and / or DNA. The present invention also provides an anti-counterfeit paper with the above-mentioned anti-counterfeit safety belt. The invention solves the problem of dehydration of the polymer security thread in the process of spreading the wide thread by adopting the water-permeable and air-permeable properties of the webbing and the non-woven fabric, and at the same time, it can bring multiple anti-counterfeiting effects to the paper through compounding with the anti-counterfeiting material.

Description

technical field [0001] The invention relates to an anti-counterfeit safety belt and a preparation method thereof, as well as anti-counterfeit paper applied to the anti-counterfeit safety belt and a preparation method thereof, belonging to the technical field of anti-counterfeit paper manufacture. Background technique [0002] Security threads and anti-counterfeit short fibers are commonly used anti-counterfeiting measures for anti-counterfeit paper. Among them, the security thread is embedded in the paper in the form of strips, and the anti-counterfeit short fibers are randomly scattered on all layers of the paper. [0003] Since Britain firstly applied full-buried security thread on banknotes in 1943, and since the window-opening security thread technology appeared in 1984, security thread (safety belt, anti-counterfeiting belt) has become an important form of anti-counterfeiting banknote paper. This method and its release method It is well known in the industry. But prese...
