Abstract
The invention discloses a method for producing anti-counterfeiting paper. At the stage of preparing pulp, the production of the anti-counterfeiting paper of colored fibers is realized by a dye and dyeing of the fibers; and the method particularly comprises the following steps of: performing step-by-step design on the conventional papermaking system to determine a dye adding point based on the conditions that the temperature of the pulp is controlled to be 20 to 60 DEG C and the concentration of the pulp is controlled to be 0.1 to 10 percent; dyeing the fiber pulp of the conventional papermaking system to obtain colored fiber pulp according to the determined dye adding point, wherein the amount of the added dye is 5 to 150ppm relative to absolute dry pulp, the flow rate of the pulp is 500 to 15,000L/minute, and the stirring rate is 50 to 500r/minute; and mixing the obtained colored fiber pulp and the fiber pulp to obtain mixed pulp and directly applying the mixed pulp to manufacturing of the anti-counterfeiting paper, wherein the proportion of the colored fiber pulp to the fiber pulp is 0.1 to 10 percent. The method has the advantages of simplicity, safety, reliability and capability of realizing continuous manufacturing of the anti-counterfeiting paper with pulp under the condition of not increasing equipment investment.
Description
Technical field
The invention belongs to the pulp and paper technology field, specifically a kind of production method of cheque paper.
Background technology
Along with the increase of continuous progress in science and technology and consumption market, the research and development of cheque paper, produce the great attention that has been subjected to each big paper plant gradually to the anti-fake paper demand.
China's cheque paper product commonly used mainly is divided into four big classes at present: water-mark fake-proof paper, safety line cheque paper, fluorescence falsification preventing paper and antiforge laser holographic paper etc.
Water-mark fake-proof paper is to obtain by the mode of adding dandyprat in the paper manufacture process, the dandyprat operated by rotary motion is between the wet end and splenium of paper machine, the watermark manufacturing effect that is chosen in waterline disappearance place mostly is comparatively desirable, mainly be to utilize the mutually an amount of displacement generation vestige of fiber in the wet web and obtain watermark, watermark has Heisui River seal, plain boiled water seal and black-plain boiled water to print three kinds, font or pattern concaved when net or roller were printed in Heisui River, font or pattern were touched water-mark fake-proof paper by obvious concave-convex sense to evagination with hand when plain boiled water was printed net or roller.As the specification of medicine adopt water-mark fake-proof paper to print mostly to form.
The safety line cheque paper mainly is to utilize special device and method, and safety line (can be the line that metal, plastics or other materials are made) is embedded ad-hoc location in the page.On safety line, can add micro letter, magnetic coating, thermo colour, anti-oxidation metal, fluorescent chemicals etc., general fake producer is difficult to imitate the safety line cheque paper, mainly be because its production technology more complicated, equipment investment is bigger, and the manufacturing of safety line own also has higher technology content.As our the RMB used in everyday safety line anti-counterfeiting technology etc. that then on the false proof basis of watermark, superposeed, improved the anti-counterfeit capability of currency greatly.
Fluorescence falsification preventing paper mainly is to utilize fluorescent fiber to present particular color under the ultraviolet light of different-waveband to carry out false proofly, and fluorescent fiber has two kinds of single wavelength and dual wavelengths, and what China used at present mainly is in the majority with single wavelength fluorescent fiber.
Antiforge laser holographic paper is divided into pad pasting paper and pure paper, and pad pasting paper is to be composited after holographic laser film is fitted in paper surface, directly laser holograph is imprinted on paper surface and pure paper is a stamping technique by the advanced person.
The cheque paper production technology had both been protected the good reputation of high-quality enterprise, had also protected consumer's interests simultaneously.Aforementioned four kinds of anti-counterfeiting technologies are no doubt better, consider but take into account production cost, ease-to-operate etc., and slightly blemish in an otherwise perfect thing still seems.
Disclosed cheque paper production technology need be added extra anti-fake material at present, as false proof coloured fibre, false proof fluorescent fiber, microcapsules technology etc.; Or increase manufacturing facilities, as water-mark fake-proof paper, safety line cheque paper etc., all can increase the production cost of cheque paper greatly.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of production method of cheque paper, this production method by the technology adjustment, is produced the cheque paper that contains color fibre on the basis of conventional paper manufacturing systems.This method is simple, safety, reliable, can need not to increase under the situation of equipment investment, realizes manufacturing paper with pulp continuously of cheque paper.
The objective of the invention is to realize by following technical scheme:
A kind of production method of cheque paper is characterized in that this method in the pulp preparation stage, utilizes the dyeing of dyestuff and fiber, realizes containing the cheque paper production of color fibre, and concrete steps are as follows:
1) is controlled at 20～60 ℃, slurry concentration at slurry temperature and is controlled on 0.1～10% the basis, conventional paper manufacturing systems is carried out segment design, determine that dyestuff adds point; Dyestuff adds that point can be chosen in after the starch dispensing machine, any interpolation point before the pulp storage tank.
2) add point according to the dyestuff of determining, the fibre stuff of conventional paper manufacturing systems is dyeed, the dyestuff addition is with respect to oven dry stock 5～150ppm, slurry flow 500～15000L/min, stir speed (S.S.) 50～500r/min, obtains the color fibre slurry;
3) the color fibre slurry that obtains is mixed with fibre stuff, wherein, the ratio of color fibre slurry and fibre stuff obtains mixed slurry 0.1～10%, mixed slurry is applied directly in the manufacturing of cheque paper.
Among the present invention, described paper pulp contains mechanical pulp, bleaching or not any in the bleach chemical pulp or several mixtures.
Described mechanical pulp is for by softwood, broadleaf or bamboo wood being any or several mixtures in the high yield mechanical pulp that makes of raw material.Mechanical pulp can make with Mechanical Method, chemical method or chemical mechanical pulping.
