Abstract
The present invention relates to a safe fiber added to anti-counterfeiting paper used for various kinds of securities, tickets, papers, trademarks, paper money credit cards, etc. The safe fiber is made from polyvinyl alcohol and contains anti-counterfeiting materials. The anti-counterfeiting materials are one or several kinds of paint, dye and luminescent materials. The safe fiber can be added to various kinds of paper with anti-counterfeiting requirements, and has an anti-counterfeiting performance. The weight percentage of the anti-counterfeiting materials in the safe fiber is from 0.3% to 6.0%. The bonding force of the safe fiber and the paper is good. After the fiber is added to the anti-counterfeiting paper, the paper is easy to produce and print and is easy to distinguish under simple light tools.
Description
The present invention relates to a kind of safety fibre that adds in the used anti-forge paper such as various marketable securities, ticket, certificate, trade mark, banknote, credit card.
U.S. Pat 4921280 disclosed utilizes polyester fiber, dyed its material of catching the energy fluorescence excitation that makes of polyamide fiber, makes safety fibre with the method.European patent NO66,854 also proposed to make some chelates itself and polyester be squeezed into silk with whirligig and make safety fibre, and above-mentioned safety fibre all is by polyester, and polyamide and similar polymer are formed.There are a lot of shortcomings in actual applications significantly in these safety fibres: (1) causes difficulty to production in the production of safety paper, for example in the paper process, used various slag removal equipments all have its certain technological requirement, especially the minor diameter sieve aperture can be easy to be stopped up by the bad safety fibre of performance, the safety fibre of forming by polyester, polyamide and similar polymer be easy to the to result in blockage production difficulty of sieve aperture, increase the workman intensity, influence product quality and increase cost.(2) safety fibre with polyester, polyamide one class material production combines not firm with paper material, it comes off on paper easily, this will bring very big difficulty to the default free securities printing, can occur such as the problem of falling in the print production such as hair, broken string, heap China ink, not only influence quality and anti-counterfeiting performance thereof that print production also directly influences default free securities.Therefore in the marketable securities field, be sought after a kind of safety fibre that can overcome above-mentioned shortcoming.
The purpose of this invention is to provide a kind of fluorescence and colored safety fibre, this safety fibre functional, and combine firmly with anti-forge paper, be easy to produce, print after being added in anti-forge paper, and it is the characteristics of user's identification easily that the marketable securities that add this safety fibre possess, and also possesses the characteristics with the simple and easy light fixture differentiation true and false.
To achieve these goals, fluorescence provided by the present invention and colored safety fibre are with the safety fibre polyvinyl alcohol manufacturing and that contain anti-fake material, described anti-fake material is one or more in pigment, the dye well luminescent material, described safety fibre can be used for adding in the false proof paper of various needs, has anti-counterfeiting performance.
Fluorescence of the present invention and colored safety fibre adopt the general chemical fiber machinery and the manufacture method of ordinary chemical fiber to make, and in fiber manufacture process, add anti-fake material, make the fiber itself of making just possess anti-counterfeiting performance, and need not reprocessing or carry out after-treatment.
The weight percent content of anti-fake material in safety fibre is 0.3%-6.0%.
Pigment in the anti-fake material, dye well luminescent material also are anti-fake material general in the marketable securities industry.These anti-fake materials comprise dyestuff, pigment and the various material such as the inorganic fluorescent chemicals with luminescence feature of various tones, organic fluorescent compounds, various compounds with security feature such as rare earth chelate all are suitable for using when making the safety fiber.Vat orange for example
Adding that fiber is manifested is orange.Permanent bordeaux
Make fiber manifest redness.Witter gram ERN
Adding make fiber under UV illumination, send blue-fluorescence, and under visible light, present white or the like.These anti-fake materials are that the fiber with the polyvinyl alcohol manufacturing is that carrier is added in the anti-forge paper, finally show with fiber colored, fluorescence in anti-forge paper, to reach false proof effect.The colour of safety fibre, the manifestation mode of fluorescence can be under visible light, present the observed versicolor colored fiber of naked eyes energy; Also can be under infrared, ultraviolet or X-ray, can make safety fibre inspire various coloured light; Or under visible light, can observe colourless or coloured fluorescent fiber.Above-mentioned these manifestation modes can be selected according to purposes, user's demand, more various anti-fake materials are prepared and are produced the different safety fibre of various uses.Because the purposes of marketable securities is different, comprise object-oriented, security classification, security type, issuing amount or the like, user's request is also had nothing in common with each other, comprise cost height, various artistic index, result of use or the like, safety fibre of the present invention can both satisfy above-mentioned different purposes and user's demand.
Safety fibre of the present invention can also satisfy various marketable securities, banknote etc. various very special quality index requests in the use, such as characteristics such as fast light, acid and alkali-resistance, anti-solvents.Safety fibre of the present invention possesses these performances can guarantee applied security of products, can increase its false proof reliability for its anti-counterfeiting performance increases multiple identification approach again.
The fiber number of safety fibre of the present invention is 0.8 -12 .Length is generally 1mm-10mm (neat sample), also can make longer any length.
Safety fibre of the present invention made by polyvinyl alcohol, and this safety fibre has overcome the shortcoming of polyesters, safety fibre such as polyamide-based.It has distinct security feature, also has the performance of index requests such as every technology that can satisfy security paper plant and security printing factory and require, quality, equipment, benefit.The adhesion of safety fibre especially of the present invention and anti-forge paper material and polyesters, safety fibre such as polyamide-based compare will be good many, through test determination, the paper intensity of anti-forge paper that is added with safety fibre of the present invention is greater than the paper intensity of the anti-forge paper that does not add safety fibre.In addition, because good with the adhesion of paper material, therefore safety fibre of the present invention can not cause any printing obstacle in high precision seal machine printing process, can not occur such as falling print production such as hair, broken string, heap China ink and print quality problem.
Safety fibre of the present invention can add various marketable securities, ticket, certificate, trade mark, banknote, credit card, stamp, reach in the anti-forge paper of highly confidential file, plays the safety anti-fake effect.
