Problems solved by technology

Both are monochrome anti-counterfeiting threads with only twisting and no weaving, which only produce specific monochromatic light under a special light source. Because the anti-counterfeiting effect of monochrome anti-counterfeiting threads is simple and easy to imitate, it leads to the possibility of forging documents, which cannot meet the requirements The current market needs f

Example Embodiment

[0097] Specific embodiment one

[0098] Granulation

[0099] Infrared excitation light powder, ultraviolet fluorescent powder and nylon 66 particles are 1: 3: 16.

[0100] The infrared excitation light powder is sufficiently mixed with ultraviolet fluorescent powder, and then the mixed powder is dried at 105 ° C for 90 min with a constant temperature drying oven;

[0101] The dry powder material and nylon 66 were mixed, followed by pouring the hopper of the screw extruded granulator, by the rotation of the feed rod, the feedstock speed is 20 to 30 rpm, and the particles are slowly Feed the inside of the machine;

[0102] The coordination of the screw and ten barrels, the temperature set value of ten barrels is: 260 ° C, 275 ° C, 275 ° C, 270 ° C, 260 ° C, 260 ° C, 260 ° C Realize the pulverization, softening, melting and compaction of the mixed particles, and continuously transmits the molding die in the head, the screw speed is 200 to 220 rpm, and the diameter of the head mold is...

Abstract

The invention discloses an electronic passport anti-counterfeiting thread. The electronic passport anti-counterfeiting thread is prepared by fully mixing ultraviolet fluorescent powder, infrared excitation light powder and nylon fibers according to the mass ratio of (1-3): (3-5): (16-25) through the steps of master batch preparation, melt spinning, single-strand fiber twisting, thread weaving and oiling. According to the technical scheme, the anti-counterfeiting effect of the passport is improved, the production loss is small in the production process, the strength of the anti-counterfeiting thread is improved, the anti-counterfeiting thread is not prone to breakage, and meanwhile the anti-counterfeiting thread is smooth through the oiling step and not prone to knotting and breakage on a machine table.

Description

[0001] The invention relates to the technical field of textiles, in particular to an electronic passport anti-counterfeiting thread. Background technique [0002] At present, there are two types of anti-counterfeiting threads for various documents in the prior art: one is a colorless ultraviolet fluorescent anti-counterfeiting thread, which is added with ultraviolet phosphors and then twisted during the production process; there is also a colorless infrared fluorescent anti-counterfeiting thread, which is produced In the process, infrared excitation powder is added and then twisted. Both are monochrome anti-counterfeiting threads with only twisting and no weaving, which only produce specific monochromatic light under a special light source. Because the anti-counterfeiting effect of monochrome anti-counterfeiting threads is simple and easy to imitate, it leads to the possibility of forging documents, which cannot meet the requirements The market currently needs anti-counterfeit...
