Embodiment 1

[0020] Example 1: anti-counterfeiting fiber, 0.05 kg of characteristic fluorescent powder as anti-counterfeiting identification material is added to 1 kg of fiber. The characteristic fluorescent powder is a complex of terbium acetate, which is green fluorescence under short-wave ultraviolet irradiation. The said fiber is polycaprolactam, and its manufacturing method is to mix characteristic fluorescent powder with polycaprolactam slices and auxiliary materials, granulate, and prepare it on a synthetic fiber spinning machine according to the melt spinning process.

Embodiment 2

[0021] Example 2: anti-counterfeit fiber, add 0.02kg of characteristic fluorescent powder as anti-counterfeit identification material to 1kg of fiber, the characteristic fluorescent powder is the complex of europium oxalate, which is red fluorescence under short-wave ultraviolet irradiation. The fiber is polyethylene terephthalate, and its manufacture method is to mix characteristic fluorescent powder with polyethylene terephthalate slices and auxiliary materials, granulate, and spin on a synthetic fiber spinning machine according to melt silk spinning. Process preparation.

Embodiment 3

[0022] Example 3: anti-counterfeit fiber, add 0.01kg characteristic fluorescent powder as anti-counterfeit identification material to 1kg fiber, described characteristic fluorescent powder is the complex of hexadecanoate of terbium, it is green fluorescence under short-wave ultraviolet irradiation. The said fiber is polycaprolactam, and its manufacturing method is to mix characteristic fluorescent powder with polycaprolactam slices and auxiliary materials, granulate, and prepare it on a synthetic fiber spinning machine according to the melt spinning process.

Abstract

The present invention relates to an anti-false fibre which can be identified by utilizing short-wave UV ray. Its technical scheme is characterized by that the characteristic fluorescent powder which can be organic acid salt compound of terbium or organic acid salt compound of europium or their mixture as anti-false identification material can be added in the fibre. Said invention also discloses an anti-false obliteration-resisting paper containing the above-mentioned anti-false fibre, and its technical scheme is characterized by that in the paper-making pulp the above-mentioned anti-false fibre and obliteration-resisting agent which can be fluorane compound, phenolic compound and guanidine compound are added. Besides, said invention also provides the method for making said paper.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting fiber and anti-alteration paper using the anti-counterfeiting fiber, in particular to an anti-counterfeiting fiber, an anti-counterfeiting and anti-alteration paper using the anti-counterfeiting fiber and a manufacturing method thereof. Background technique [0002] Criminal activities such as forging passports, ID cards and other documents, credit cards, securities, bank vouchers, value-added tax invoices, customs documents, diplomas, lottery tickets, trademarks and other criminal activities are becoming more and more serious, causing extremely bad political influence and bringing State, collective and individual bring serious economic losses. In order to prevent and combat this kind of criminal activities, the research and development of anti-counterfeiting technology and its products have been widely carried out at home and abroad. In the cases of forgery and alteration, the cases of alterin...
