Description
Technical field
The present invention relates to a kind of fluorescence colored fibre, said fluorescence colored fibre has been labeled first luminescent substance and has been made up of adhesive at least to a certain extent, relates to the thin slice that includes color fibre and relates to the file with said colored fibre.The invention still further relates to the method for making the fluorescence colored fibre, the method for making the method for the thin slice of being with the fluorescence colored fibre and making the file of band fluorescence colored fibre.
Prior art
From prior art known make the method for luminous colored fibre and introduce them, especially in the manufacture process of paper, they are incorporated into the method in the paper.
From DE 41 33 977 A1 known the method for dyeing organic fiber, its dope dyeing (spin dyeing) that is different from prior art is that it uses the aqueous solution of cationic polymer and uses the water slurry of pigment a spot of fiber that dyes then.The particle size of the particle that in the case of any possible, is used to dye should＜10 μ m.
From DE 37 19 48 A known make the method that the ring of light is produced colored fibre.Be embedded into the paper in it through dry colored fibre, these colored fibres make paper stamp color, thus the ring of light be formed on colored fibre around, can be easy to remove fiber like this.
Have the safety paper of color fibre from EP 1 268 935 B1 cicada, different luminous colored fibres are embedded into, and purpose is in the different sub zone of paper, to encode.Luminescent substance can be introduced in the colored fibre or only be applied on their surface.The characteristics of luminescence for example is the die-away time of emission wavelength or luminous rays.
A shortcoming of this prior art is that the types of patterns of introducing is very limited.Strip pattern is only disclosed in EP 1 268 935 B1.In addition, the method for making this safety paper can not be used to make the file based on plastics, because the colored fibre loosely is arranged on the hard frosting pattern that is therefore distributed arbitrarily and can not replication application.
Have the safety paper of the colored fibre of at least a type from DE 103 24 630 A1 cicada, be used to make the marketable securities of processing by safety paper (valuable document), for example banknote.Colored fibre comprises the luminescent substance with peculiar characteristics of luminescence.These colored fibres can be designed to bicomponent fiber, wherein form core sheath structure.If sheath partly is that low molten material and preferred in from 95 to 150 ℃ temperature range, the fusing will be to have advantage especially.These fibers demonstrate bondingly better in subregion, and wherein colored fibre is added in the manufacture process of paper.The manufacturing of colored fibre for example can be used melt spinning (melt spinning), wet type spinning (wet spinning), or dry spinning (dry spinning) technology and realizing.Colored fibre has special geometric format and information can be coded on this geometric format.Yet shortcoming is that the check needs technology of this fiber is auxiliary and time-consuming.For example, the form of colored fibre can be seen under light microscope.But this process is inappropriate for quick test, for example, and in the point of sale.
Prior art problems and the object of the invention
For the colored fibre of prior art, the problem of existence is that these can be easy to duplicated through being pressed into fluorochrome.For this reason, the adulterator uses fuel on forging document, to print the image of the fiber that arbitrarily distributes.These counterfeits can be detected, but very hard, for example by means of microscope.
Another problem according to the colored fibre of prior art is in the file of introducing based on plastics, especially introduces in the file of making through the laminated plastic thin slice.Use known method, the fiber that closes of layer broadcasted sowing therein on the thin slice and therefore produced pattern at random.Yet, to compare with made of paper making, the problem of doing like this is that fiber does not bond on the thin slice by any way, does not close because they carry out layer.Like this, we can know that a large amount of fibers is distributed by manufactory and therefore possibly make the other products that should not comprise any colored fibre or should comprise different fibers privately.
Based on this, the purpose of this invention is to provide a kind of colored fibre, it is easy to check, easy to implement and structure, and integrated especially be integrated in the plastic document simple.
