Embodiment 2
The present embodiment tells about a kind of preparation containing amorphous fiber but amorphous fiber sightless cheque paper under visible light
Method.
Glass fluxing technique amorphous fiber is prepared using Taylor's spin processes, the external diameter of amorphous fiber is 25 μm, and inner core diameter is 16 μ
M, cut into the chopped fiber that length is 4mm.
After amorphous fiber prepares, the manufacture of cheque paper can be carried out.Its process is followed successively by refining process, tankman
Sequence, process of manufacturing paper with pulp.
Refining process：Paper pulp fiber (such as wood pulp, straw pulp) is prepared into refining in jordan.
Slurrying process：Paper pulp after refining is equipped with the filler with covering effect, such as titanium dioxide, talcum powder, kaolinite
Soil etc., and stir；Paper pulp after refining is pressed into 200m/m2Surface density be equipped with amorphous fiber, and stir.
Manufacture paper with pulp process：Paper pulp is manufactured paper with pulp with paper machine, first layer is from the paper pulp for not containing amorphous fiber, thickness
50μm；The second layer is selected containing the with slurry of amorphous fiber, and thickness is 25 μm；The same first layer of third layer.Prepared cheque paper, it is non-
Crystal fiber exists only in intermediate layer.Because superficial layer contains the fillers such as titanium dioxide, there is good covering effect so that can
See under light, the distribution of amorphous fiber is difficult to distinguish.
But after using magnetic image scanning sensor scanning cheque paper, magnetic fibre distribution map can be obtained, i.e., is believed in magnetic
Under number, paper has texture anti-fake function.
Described in embodiment 1, induced signal of the amorphous fiber under alternating magnetic field is gathered using way of electromagnetic induction, can
Detect due to large Barkhusen effect and caused pulse signal.The code pattern of pulse signal can so be formed.
Because the distribution of amorphous fiber is invisible under visible light so that this cheque paper has very strong disguise,
The modes such as duplicating are prevented to destruction caused by this anti-counterfeiting performance.Due to needing to use magnetic image scanning sensor and special detection
The instrument of large Barkhusen effect is detected, and this cheque paper, which is adapted for use with, false proof requires high field.
Described above is only the exemplary embodiment of the disclosure, not for the protection domain of the limitation disclosure, this public affairs
The protection domain opened is determined by appended claim.
