Abstract

The invention relates to a wavy anti-counterfeiting fiber and paper and a paperboard containing the same. The wavy anti-counterfeiting fiber is characterized in that: the anti-counterfeiting fiber is wavy, and the fiber at least contains a wave crest point 2 and a wave trough point 3. Compared with the conventional bent fibers and linear fibers, the invention provides a vision distinguishing characteristic, the anti-counterfeiting fiber has more vision characteristic combinations, and the wavy anti-counterfeiting fiber is more difficult to counterfeit.

Description

A kind of wavy anti-false fiber and contain the paper and the cardboard of this anti-false fiber

Technical field

The present invention relates to a kind of anti-false fiber and contain the paper and the cardboard of this anti-false fiber, particularly a kind ofly be shaped as wavy and contain the paper and the cardboard of this wavy anti-false fiber.

Background technology

Anti-false fiber has been widely used in the production of cheque paper as a kind of basic papermaking anti-fake material, one of problem that existing anti-false fiber exists is the personalization of fiber, fluorescent fiber for example, global currency all is red, blue, yellow, green several monochromatic fiber, visual signature is not distinguished, shape or linearity, bending, such consequence has big influence to antifalse effect, the fake producer needs only the arbitrary link at logistics progress, fiber production link for example, obtain this fiber in papermaking link or the printing link or the paper of this fiber is arranged, all can remove to forge the anti-fake product of any one identical fibre feature.

On the other hand, the shape of existing anti-false fiber is the state of nature after the spinning substantially, does not rely on any technology, linearity for example, and therefore the bending fiber with regard to the shape of anti-false fiber, can not produce any antifalse effect.

Summary of the invention

The object of the present invention is to provide and a kind ofly be shaped as wavy and contain the paper and the cardboard of this wavy anti-false fiber, Yi Qian curved fiber and straight line fiber relatively, a kind of vision distinguishing characteristic is provided, make anti-false fiber that more visual signature combination be arranged, and the anti-false fiber of wave-like more is difficult to forge.

The object of the present invention is achieved like this:

A kind of wavy anti-false fiber is characterized in that, described anti-false fiber 1 is wavy, contains a wave crest point 2 and a trough point 3 on the fiber at least.

Further, wave crest point 2 is no less than 3 with the sum of counting of trough point 3.

Can select the sum of counting of wave crest point 2 and trough point 3 to equal 2 is a visual signature, and it is a visual signature that sum equals 3, and it is a visual signature that sum equals 4.The purpose of Xuan Zeing is to allow the personalized more of fiber like this.

Further, have two look sections at least on a fiber.For example: coloured red, coloured blue two look sections on the fiber; Fluorescein, two look sections of fluorescent blue are arranged on the fiber.

Further, the color of described fiber is the iridescent of the irradiation luminous material production of exciting light.Described exciting light comprises ultraviolet light and infrared light.

Further, described anti-false fiber has surface 4 and two surfaces, 5 two surfaces, surface, and the color on surface 4 has tangible vision difference with the color on surface 5.The stereochemical structure of described fiber can guarantee when the fiber freely falling body to parallel with horizontal plane when surperficial fiber surface A parallel with fiber surface B with horizontal plane.

Further, described surperficial 4 are made up of the polychrome section, and surface 5 is made up of monochromatic section.

Described look section can be a fluorescent fiber, for example surface 4 be one section coloured red, one section fluorescent blue, the surface 5 is a fluorescent red.

Further, the surface 4 of described anti-false fiber and surface 5 are the polychrome section.

Further, naked eyes are directly observed under the sunshine, and having a section fibre on the described anti-false fiber at least is colourless section.

A kind of cheque paper that is distributed with above-mentioned anti-false fiber is characterized in that, in the described anti-false fiber distribution pulp layer.

Further, naked eyes are directly observed under the sunshine, have one section colourless section on the anti-false fiber in the paper at least, it is characterized in that, printing opacity is observed, and colourless section in the paper in the anti-false fiber is transparent.For example: have on the fiber one section coloured red, one section colourless section; Described colourless section can be fluorescent fiber, and reason is that the fluorescent fiber perusal also is colourless, and copying pressurizes in the paper can produce transparent effect in the paper.Transparent section can be stopped the described visual signature of printing imitation in the paper.

A kind of anti-fake paper board that is distributed with above-mentioned anti-false fiber is characterized in that, described cheque paper is that anti-false fiber is distributed in the top layer of pulp layer by the compound cardboard of multilayer pulp layer.

Further, described anti-fake paper board is by the compound cardboard of multilayer pulp layer, has one deck dyeing pulp layer in the inner pulp layer at least, and described dyeing pulp layer and adjacent pulp layer have tangible vision difference.

Effect of the present invention is fairly obvious, has not only enriched the vision combination of anti-counterfeiting characteristic, and has also strengthened the anti-system of the difficulty intensity of anti-false fiber, can make different products, different target clients that the visual signature of different anti-false fibers is arranged.
