preparation example Construction

[0044] The flow process of the preparation method of the anti-counterfeiting cloth paper provided by the present invention is as follows: figure 2 As shown, it can be carried out according to the following specific steps:

[0045] To prepare a cloth containing anti-counterfeiting material (which can be called anti-counterfeiting cloth), the following methods can be used:

[0046] 1. Anti-counterfeiting materials are added by printing: use a loom to weave fabrics through ordinary plain weaving; add anti-counterfeiting materials (such as fluorescent materials, temperature-changing materials, magnetic materials, etc.) to ink, and transfer them through a screen printing machine Put it on the above cloth to get the anti-counterfeit cloth, or add the above-mentioned anti-counterfeit material into the ink and transfer it to the above-mentioned cloth through a digital printing machine to get the anti-counterfeit cloth.

[0047] 2. Anti-counterfeiting materials are added in the form ...

Embodiment 1

[0082] This embodiment provides a kind of anti-counterfeiting cloth paper, which has a sandwich structure formed by one layer of cloth 102 (thickness is 100 μm) and two layers of paper 101, such as figure 1 Shown, wherein, above-mentioned cloth contains thermosensitive material.

[0083] The anti-counterfeiting cloth paper is prepared through the following steps:

[0084] (1) Weaving: use viscose silk to weave into cloth, wherein the yarn interweaving density is: warp density 30 threads / cm, weft density 30 threads / cm;

[0085] (2) Composite cloth and anti-counterfeiting material: Add 2% (by ink weight) of inorganic thermochromic substance (when heated, the substance can change from colorless to green, and the discoloration temperature is 60°C) to ordinary ink to obtain heat-sensitive ink, The maple leaf pattern is printed on the cloth by thermal transfer, the maple leaves are evenly distributed on the cloth, the distance between the maple leaves is controlled to 10mm, and the...

Embodiment 2

[0092] This embodiment provides a kind of anti-counterfeit cloth paper, which has a sandwich structure formed by one layer of polyamide filament cloth and two layers of paper, wherein the polyamide filament cloth contains blue ultraviolet fluorescent powder, which is colorless to 50°C. Red temperature-changing powder.

[0093] The anti-counterfeiting cloth paper is prepared through the following steps:

[0094] (1) Combining fibers with anti-counterfeiting materials: In the spinning process of polyamide filaments, blue ultraviolet fluorescent powder and 50°C colorless to red temperature-changing powder are added to the spinning stock solution (addition amount can be adjusted) Controlled to 0.5-9.5% of the quality of the spinning stock solution), a polyamide anti-counterfeit filament with both fluorescent effect and temperature-changing effect is obtained by melt spinning, and the fiber fineness is 50D;

[0095] (2) Weaving: Use polyamide filament anti-counterfeiting fiber as ...

Abstract

The invention relates to an anti-counterfeit cloth paper and a preparation method thereof. The anti-counterfeit cloth paper has a sandwich structure composed of two layers of paper sheets and one layer of cloth. The present invention also provides a method for preparing the above-mentioned anti-counterfeit cloth paper, which includes the following steps: using a cylinder paper machine to form at least two layers of wet paper sheets with double cylinders; compounding at least one layer of cloth between the wet paper sheets on at least two sides , form a sandwich structure, and complete subsequent papermaking to obtain the anti-counterfeit cloth paper. The anti-counterfeit cloth paper of the present invention is compounded with cloth with specific properties in the middle of the paper, realizing the combination of two different technical fields of papermaking and textile, making the performance of cloth and paper complementary, enhancing the physical strength of paper, and greatly improving the physical properties of paper At the same time, it does not affect the performance of paper printing. It can also give a variety of anti-counterfeiting information during the weaving and processing of cloth, greatly improving the anti-counterfeiting performance of cloth and paper, and bringing novel expressions and effects to paper anti-counterfeiting technology.

Description

technical field [0001] The invention relates to an anti-counterfeit paper and a preparation method thereof, in particular to an anti-counterfeit cloth paper and a preparation method thereof, and belongs to the technical field of anti-counterfeit paper preparation. Background technique [0002] Paper anti-counterfeiting is an important component in the field of anti-counterfeiting technology. Now, in order to improve the anti-counterfeiting technology level of paper, anti-counterfeiting paper with novel anti-counterfeiting effect and high anti-counterfeiting function is often obtained by adding anti-counterfeiting materials to paper. [0003] However, while the anti-counterfeiting function of paper is improved, due to the addition of anti-counterfeiting materials, it often leads to the reduction of the strength and other properties of the paper, and paper products, especially banknotes, are often folded or curled during use. If the strength of the paper If the temperature is...
