Problems solved by technology

The paper mill also had three quality accidents in which residual fiber polluted ordinary white paper, which once caused residual fiber to appear in a domestic cigarette paper, resulting in the paper mill being returned by the cigarette factory to more than 180 tons of cigarette paper, resulting in an economic loss of 200 yuan for the paper mill More than ten thousand yuan

Embodiment 1

[0130] Such as Figure 11 As shown, referring to the composite production process of the utility model patent "laser holographic safety thread composite packaging box (CN2399334Y)", the surface layer of the transparent BOPP film is composited with the bottom layer of white PE, and at the same time, a strand of 7 x 0.5D black polyester Napped yarn—fancy yarn, pulled out from the unwinder and buried between its two layers, crushed and deformed (flattened) by a super calender and ensured that all the hairs on it are stuck, clamped, Stationary to create a substrate for fancy yarns with napped yarns inside.

[0131] Such as figure 1 As shown, the above-mentioned brushed yarn-type printing material is used to print printed matter, and a unique sequence code containing a link address—code—is printed on each printed matter with an inkjet printer.

[0132] Prepare an industrial-grade digital camera. After the flat texture string releases the stress and is completely shaped, each cod...

Embodiment 2

[0139] Such as Figure 12 As shown, the 1st and 2nd are loop yarns, and the 3rd is textured yarn, both of which are fancy yarns, pull them out from the pay-off device, place them at a certain distance, and bury them between the two layers of pulp. During this time, it is rolled and deformed (flattened) by a super calender to produce fancy yarn-like printing materials embedded with loop yarn and textured yarn. This printing material can be used to print such as figure 2 Prints shown. Other steps can be the same as in the embodiment.

Embodiment 3

[0141] Such as Figure 13 As shown, bundles of colorful wrapped toothbrush yarns—fancy yarns—are pulled out from the unwinder, spaced at a certain distance, buried between two layers of pulp, and rolled and deformed by a super calender (Squeeze), the thickness of the flat texture string after flattening is preferably 25-35μm, so as to produce a printing material embedded with fancy yarn wrapped with toothbrush yarn. This printing material can be used to print such as image 3 Prints shown. Other steps can be the same as in the embodiment.

Abstract

A hand-tear texture anti-counterfeit method and a product and a material thereof are provided. Fancy yarn is embedded in printed matters and substrates, fancy yarn and its individual element are squeezed and shaped into a flat texture string. Personality information of flat texture strings is collected and stored as texture information files in the database of anti-counterfeit checking system. Themethod overcomes the drawbacks of needle pick fiber (texture), achieves the purpose of manual texture detection, can facilitate the public to discriminate the true and false texture by hand, avoids the trouble of anti-counterfeit application of needle pick texture, simplifies the production of texture paper, and avoids the residual fibers from polluting the production workshop environment of ordinary white paper.

Description

technical field [0001] The invention belongs to the field of information query anti-counterfeiting technology, and specifically relates to an improved application of the Chinese patents "Structural texture anti-counterfeiting method (CN1074563C)" and "Structural texture anti-counterfeiting marker (CN2365711Y)". Background technique [0002] The "structural texture anti-counterfeiting method (CN1074563C)" invented by the inventor of this application (Mr. Chen Mingfa) has obtained Chinese patents, US patents (certificate number US6623041), Russian patents (certificate number 2202127), Korean patents (certificate number 0419436), Vietnam Patent (Certificate No. 3347) and other international patents (PCT / CN99 / 00102). "Structural texture anti-counterfeiting marker (CN2365711Y)" has obtained a Chinese utility model patent. It selects a printing material (2) with a random structure texture (1) (such as the texture formed by black chemical fibers with a length of 2-3 mm and a thick...
