The invention relates to an anti-counterfeiting safety belt with machine-readable performance and/or machine-readable coding function and anti-counterfeiting paper, belonging to the technical field of anti-counterfeiting paper manufacturing.

Background

Since the first application of fully-buried security threads to banknotes in the uk in 1943 and the emergence of windowed security thread technology in 1984, security threads (security belts, security bands) have become an important form of security for banknote paper, which is known in the industry as a polymer film. In order to break through the limitation that the width of a polymer film type safety line is limited by the dehydration effect, the invention adopts a weaving or non-woven fabric form to obtain a novel anti-counterfeiting additive form, the anti-counterfeiting elements of the anti-counterfeiting safety belt adopt the forms of melting, dipping, printing and the like and the combination of woven belts, the anti-counterfeiting form is emphasized on the visual change of the anti-counterfeiting woven belts, and the anti-counterfeiting form is visual and single.

In order to overcome the disadvantages and shortcomings of the above-mentioned cases, it is an object of the present invention to provide an anti-counterfeit seat belt with machine-readable performance and/or machine-readable encoding function. The anti-counterfeiting safety belt provided by the invention has a machine-readable coding function, breaks through simple visual change, and has more enhanced and hidden anti-counterfeiting capability.

Similarly, the anti-counterfeiting paper provided by the invention also has the instrument detectable performance or the instrument detectable coding performance.

In order to achieve the above object, the present invention provides an anti-counterfeit safety belt with machine-readable performance and/or machine-readable coding function, which is a strip fabric formed by respectively arranging and combining a series of signal characteristics including color, quantity and position for warp and weft according to the signal coding requirement to be realized, and then interweaving the warp and weft, wherein the warp comprises at least one anti-counterfeit filament with machine-readable signal, and/or the weft comprises at least one (section of) anti-counterfeit filament with machine-readable signal.

In the above anti-counterfeit safety belt with machine-readable performance and/or machine-readable coding function, preferably, the anti-counterfeit filament with machine-readable signal (anti-counterfeit filament with instrument detection performance) includes one or more of conductive fiber, magnetic fiber, nuclear magnetic material fiber, infrared material fiber and ultraviolet material fiber. The resistance or current signal change of the conductive fiber can be used as a machine-readable detection index, the electromagnetic signal change of the magnetic fiber, the nuclear magnetic signal of the nuclear magnetic material fiber, the emission spectral lines of the infrared material fiber and the ultraviolet material fiber and the like can also be used as a machine-readable detection index.

In the above anti-counterfeit safety belt with machine-readable property and/or machine-readable coding function, the width of the anti-counterfeit safety belt is preferably 1-30mm, more preferably 1.5-25 mm.

In the above anti-counterfeit safety belt with machine-readable performance and/or machine-readable coding function, preferably, the anti-counterfeit safety belt is prepared according to the following steps:

adopting a differential warping mode, taking anti-counterfeiting filaments and/or conventional wires with machine-readable signals as warps, and carrying out arrangement combination on the anti-counterfeiting filaments and/or the conventional wires with the machine-readable signals according to signal codes to be realized, wherein the characteristics comprise colors, quantity and positions;

adopting anti-counterfeiting filaments and/or conventional wires with machine-readable signals as wefts, arranging and combining the anti-counterfeiting filaments and/or the conventional wires with characteristics including color, quantity and position according to signal codes to be realized, and weaving in a weft-changing mode to obtain the anti-counterfeiting safety belt with machine-readable performance and/or machine-readable coding function.

In the anti-counterfeiting safety belt with the machine-readable performance and/or the machine-readable coding function, preferably, the preparation method of the anti-counterfeiting safety belt further comprises a process of selecting warps or wefts with different diameters so that the obtained anti-counterfeiting safety belt has the tactile perception performance.

In the above anti-counterfeit safety belt with machine-readable performance and/or machine-readable coding function, preferably, the conventional thread material includes one or a combination of several of polyester filament, polyethylene filament, nylon filament and aramid filament.

In the above anti-counterfeit safety belt with machine-readable property and/or machine-readable code function, preferably, the signal code includes one or a combination of several of the existence of signal, the strength of signal, the kind of signal and the continuous width of signal.

Wherein, the existence of the signal can be realized by adopting an anti-counterfeiting filament or a conventional wire with a machine-readable signal; the strength of the signal can be realized by selecting anti-counterfeiting filaments with different signal (such as current signal, electromagnetic signal and the like) strengths; the type of the signal can be realized by selecting anti-counterfeiting filaments with different types of machine-readable signals, such as conductive fibers, magnetic fibers, nuclear magnetic material fibers, infrared material fibers or ultraviolet material fibers; the width of the signal duration can be realized by the frequency of the signal repetition in the unit length, such as: the number of the anti-counterfeiting filaments with signals continuously appearing on the warp threads and the number of the round trip times of the continuous weft threads on the weft threads.

Specifically, the key to realizing the change of the braid warp signal is to realize the warping process of different wires, and the main purpose of the process is as follows: according to the anti-counterfeiting requirement, a warping process design is carried out, warp yarns with target number and length are led out from different winding bobbins to form a yarn sheet, the warp yarns have uniform tension and are tightly wound on a warping shaft in parallel, and preliminary preparation is made for forming a loom beam. Different from the conventional textile technology, the purpose of warping here is to ensure that the yarns of different warps are uniformly arranged and the winding density is uniform, and to realize the arrangement of different wires required by the codes according to the design complexity of the anti-counterfeiting codes. That is, different machine-readable signals have different machine-readable feature detection methods, and thus the methods for realizing machine-reading and encoding thereof are different. Such as: to achieve machine-readable and encoding of magnetic signals, combinations of three variables are available, detected, and combinations occur, of which the following are merely three typical examples: 1) presence or absence of a magnetic signal; 2) the strength of the magnetic signal is strong and weak; 3) the frequency with which the magnetic signal repeats per unit length, i.e., its width. Thus, the encoding of the above three variables can be achieved. Such as: a first encoding form: 1) presence or absence; presence or absence; 2) the second encoding form: none, strong and weak; none, strong and weak; 3) none (width signal a), strong (width signal B), weak (width signal C).

Such as: the number of the arranged warps, the arrangement and the circulation mode of the warps, and the like. In the present invention, different warps are specifically characterized by carrying different characteristics, such as: different signal types are combined.

The following steps are repeated: infrared characteristics, conductive fibers, magnetic resonance materials, and the like. Generally, the same material of the wire is used as much as possible to ensure that the mechanical correlation properties such as the breaking elongation and the initial modulus of the wire are consistent, thereby ensuring the overall smoothness of the mesh belt. Under special circumstances, if the process of adding special materials affects the performance of the anti-counterfeiting material, especially the anti-counterfeiting performance, and the process of the wire is limited, the warping process becomes more important, and the strength, elasticity and the like of different yarns can be ensured to be consistent through the process, so that the weaving process can be normally carried out.

Meanwhile, the process itself is a technological process aiming at anti-counterfeiting: in order to improve the anti-counterfeiting effect of the mesh belt, a manufacturer can adopt a certain hidden mode, the wires with the anti-counterfeiting effect and the wires without the anti-counterfeiting effect have consistency in appearance, and the difference between the wires and the wires can be shown only when special and corresponding instruments are used. The security feature thus has a single-blind character, namely: when the counterfeiter does not understand the way of the decoding, the woven tape with the machine-readable code is very difficult to decode, and therefore, the way in which the warping is performed is not known.

The invention also provides a preparation method of the anti-counterfeiting safety belt with the machine-readable performance and/or the machine-readable coding function, which comprises the following steps:

The more the exchangeable types of warps are, the more accurate the exchange controllable degree is, the more various the encoding forms can be formed, and the stronger the anti-counterfeiting capability is.

The more exchangeable types of the weft, the more accurate the exchange controllable degree, the more various the encoding forms which can be formed, and the stronger the anti-counterfeiting capability.

The two modes are combined, so that the anti-counterfeiting effect is better.

In the above preparation method, preferably, the preparation method further comprises a process of selecting warps or wefts with different diameters so that the obtained anti-counterfeiting safety belt has tactile sensation performance.

In the above preparation method, preferably, the signal code includes one or a combination of several of the existence of the signal, the strength of the signal, the kind of the signal, and the width of the signal duration.

In the preparation method, the anti-counterfeiting filament with the machine-readable anti-counterfeiting effect (the anti-counterfeiting filament with the machine-readable signal) can form a signal code through the arrangement of different organizational structures, and thus the machine-readable performance with the code characteristic is generated, so that the anti-counterfeiting hierarchy of the prepared anti-counterfeiting safety belt is further improved.

The invention also provides anti-counterfeiting paper which contains the anti-counterfeiting safety belt with the machine-readable performance and/or the machine-readable coding function.

In the above security paper, preferably, the security belt with machine-readable performance and/or machine-readable coding function is embedded inside the security paper;

more preferably, the anti-counterfeiting safety belt with the machine-readable performance and/or the machine-readable coding function is embedded into the anti-counterfeiting paper in a windowing or full-buried mode.

According to a specific embodiment of the present invention, the security paper for applying the security strip with machine-readable property and/or machine-readable coding function may be prepared by a conventional method in the art. As in the embodiment of the present invention, the security paper can be obtained by combining the security belt with paper by releasing the security thread.

The anti-counterfeiting safety belt is prepared by adopting the fabric weave structure, and the dehydration performance of the anti-counterfeiting belt is improved by adjusting the density (namely the warp density and the weft density) of the fabric weave structure, so that the anti-counterfeiting safety belt has the possibility of unlimited relative width in the production process of combining with paper, and the anti-counterfeiting paper containing the weave structure has stronger visual impact force. And with the increase of the width of the anti-counterfeiting safety belt, the anti-counterfeiting safety belt has the possibility of combining multiple types and multiple layers of anti-counterfeiting forms, such as: signal detection, signal coding detection, visual color and texture change; in the anti-counterfeiting paper applied with the anti-counterfeiting safety belt, the combination of the thickness of the wire rods can be sensed by touch. Therefore, the anti-counterfeiting safety belt provided by the invention has comprehensive functions of one line (vision and touch), two lines (instrument detection), three lines (signal coding) and the like.
