Description
One, technical field
The present invention relates to a kind of positioning distributed fiber anti-counterfeiting paper and manufacture method thereof, belong to pulp technology for making paper.
Two, background technology
Anti-false fiber paper extensive use on the anti-forge papers such as marketable securities and product description, and adding and the distribution mode of false proof silk in paper production is similar, it mostly is random distribution in paper, also have and see the production that indivedual reports have the fibre strip cheque paper, do not locate patent and the report that is distributed in the specific geometrical pattern but also see anti-false fiber.Such as the positioning anti-fake wire production method that publication number CN1763312A patent is mentioned, product is certain the ad-hoc location location continuous distributed anti-false fiber silk at the paper banner, and mostly other patent is random and is distributed in the paper.Random distribution anti-false fiber yarn production method is simple, does not need special equipment and flow process, and no matter fourdrinier or cylinder machine can be produced very smoothly, copys easily, and antifalse effect is poor.
Three, summary of the invention
The object of the invention is to solve the deficiency that above-mentioned prior art exists, a kind of positioning distributed fiber anti-counterfeiting paper and manufacture method thereof are provided, false proof silk location is distributed in the discontinuous geometrical pattern special on the paper in this cheque paper, and geometrical pattern does not have anti-false fiber to distribute outward.
The present invention is achieved through the following technical solutions:
Filametntary location distributes and finishes at two cylinders or multivat machine.At first make the geometrical pattern of hollow out at a net dehydration wire side, place beyond the geometrical pattern is processed into the zone of not dewatering with curable filler or overcover, one net is added the false proof silk that needs with slurry, stir, when start is produced behind the online slurry, dehydration forms pulp layer in the geometrical pattern, and do not dewater in the zone beyond the pattern, with regard to not all right pulping layer, such net has just formed the little slurry synusia of one by one geometry that needs, and the slurry layer contains one or more anti-false fibers, and the slurry layer is taken away by the felt under the couch roll, taken away by felt smoothly in order to solve how much little scraps of paper, increased suction flat box in the exit of couch roll.It is compound to move forward the slurry layer that forms with two nets and many nets with the felt of geometrical pattern slurry layer, further pass through press dewatering, oven dry, top sizing, again oven dry, press polish, batch, cut, finish the production of finished product location anti-false fiber paper, thereby reach the purpose of producing positioning distributed fiber anti-counterfeiting paper.
A kind of positioning distributed fiber anti-counterfeiting paper, its special feature are that rule is furnished with anti-false fiber 2 on paper 1 plane;

The manufacture method of above-mentioned a kind of positioning distributed fiber anti-counterfeiting paper:
A, selection anti-false fiber silk, make location distributed fibers net:
At first determine false proof silk kind, length, quantity according to customer requirement, the geometrical pattern of distributed areas, location and arrangement mode on the net, then paint or the single face adhesive tape covers the extra-regional position of geometrical pattern at papermaking wire-cloth, reach the purpose of not dewatering.
The production of b, body paper:
1), pulping: adopt hydrabrusher that paper pulp is smashed decomposition, become the paper pulp of concentration 3-4%, be extracted into pulp storage tank with pump;
2), making beating furnishing: through the mill beating degree 30-50 ° SR that pulls an oar, be put into the furnishing pond, add various auxiliary materials by formulation weight part and carry out furnishing;
3), minute slurry: the furnishing disposed slurry divides and adds false proof silk slurry and do not add two kinds in false proof silk slurry, adds slurry pumping to the first net material well of false proof silk, does not add slurry pumping to the second net material well and other net material well of false proof silk;
4), paper moulding: adopt cylinder paper machine to finish the paper moulding, minimum two of starching net, the slurry of fibre-bearing silk forms the geometry pulp layer in a net (location fiber web) dehydration, then taken away by felt and net the pulp layer that does not contain false proof silk that forms with two nets and back more and be combined and form paper l Water Paper page or leaf, finish the moulding of location anti-false fiber paper, Substance 30-200 g/m, 20-100 m/min of the paper machine production speed of a motor vehicle;
5), press dewatering: through 2 to 3 road press dewaterings, squeeze pressure position 50-100KN/m;
6), drying: adopt steam dryer, baking temperature 60-120 ℃;
7), top sizing: adopt two roller applying glues, resin added is 1-4 g/m.
8), press polish: 5-7 roll calendar machine, pressure 20-100KN/m are adopted in press polish.
Advantage of the present invention is that product appearance has the two-layer false proof measure that the location distributed fibers is false proof and geometrical pattern is false proof, and popular discriminating is easy, and security pattern variation kind is many, and production difficulty is large, and antifalse effect is good.
