Definitions

  • the invention relates to a method for producing a tissue, as well as a Test method for testing the authenticity of the fabric in accordance with Generic term of the independent claim of the respective category.
  • branded products are usually with a brand label which gives the consumer the origin and authenticity of the product To document the product.
  • brand labels are becoming commonplace falsified, which often causes considerable damage to the brand manufacturer arises.
  • This problem is in particular in textile products, such as Garments but also with other woven products such as tarpaulins for Tents, or for example in safety belts for the automotive or Aerospace industry and many other areas where woven Materials find use, widely used.
  • non-textile Products are often woven for a variety of reasons Label provided, glued, sewn or in another suitable Is attached to the product for identification.
  • the object of the invention is therefore to provide a novel process for the production a fabric with a tamper-proof identification feature to propose, as well as a corresponding procedure for the reliable and simple verification of the authenticity of a method manufactured by the method To provide tissue.
  • a method for producing a fabric is disclosed proposed, wherein in a basic structure of the tissue a predetermined Woven pattern, which is used as an identifying feature for testing the Authenticity of the tissue is used, as well as a test method, with which the authenticity of the inventive method produced fabric is verifiable.
  • the pattern may be a regular structure, such as a geometric pattern or even a woven serial number or similar, or another woven identifier.
  • the pattern is preferred no regular structure, but can for example generated by it be that in the control of the loom in the weaving process certain Parameters, for example control parameters in a computer program to control the loom, set more or less arbitrarily be so that the pattern has no regular structure but rather stochastic character.
  • the pattern in the basic structure of the fabric can be characterized, for example be generated by controlling the strength of the attack of the Batten of a weaving machine the pattern according to a predetermined scheme is woven. That is, the strength with which the batten one Weft strikes can be varied according to a predetermined scheme so that the fabric is a pattern with a characteristic structure which is not reproducible if the given scheme for Control of the strength of the attack in the web process is not known.
  • Another beneficial measure can be the change of one Opening angle in the shedding according to a predetermined scheme.
  • a suitable control of a Breithalters the loom after a given scheme may in the context of the inventive Method advantageous for weaving a predetermined pattern in the Basic structure of the tissue can be used.
  • weft threads and / or warp threads can be made from different ones Materials are used according to a given scheme Weaving the fabric to be woven.
  • the weft threads and / or warp threads can also have different thicknesses, different Have surface finishes or in other properties which are used to generate the predetermined pattern in the Basic structure of the tissue are suitable.
  • the pattern is woven in such a way that it without a technical measuring device can not be detected by eye.
  • the pattern forms a kind of substructure in the basic structure of the tissue, so that the pattern in the tissue with the naked eye, the means without optical aids, is not recognizable.
  • the invention also relates to the tissue that after the inventive method, for example according to one of the above described embodiments of the method, is produced.
  • the Fabric thus includes a basic structure in which a specifiable pattern woven as an indentifying feature to test the authenticity of the product Tissue is suitable. Preference is given to the pattern without technical Measuring device in the tissue with the eye not visible.
  • the fabric is a registered or unregistered brand label, the for example, incorporated in a woven product, or as a sticker, Badge, or as a brand label attached to sew on a product is to demonstrate the authenticity of the product. It can do that Brand label of course in any other way on the Be attached product and the product itself does not need a woven It can be product but it can be any product with one woven brand label trade.
  • a fake tissue from a real tissue that has been prepared according to the inventive method, to differentiate can, will continue a test procedure to test the authenticity of a Test tissue by comparison with a tissue with a predeterminable Sample in a basic structure proposed in which test method the Test fabric detected metrologically with a technical measuring device, and used to create an at least one-dimensional digital test data set which is representative of the test tissue.
  • the digital check record is by a one- or multi-dimensional transformation into a second Test data set transformed to test the authenticity of the test fabric the tissue is used as a reference, the tissue metrologically is captured, and from this an at least one-dimensional digital Reference data set that is representative of the tissue.
  • the digital reference data set is characterized by a one- or multi-dimensional Transform transformed into a second reference data set, so that by comparing the second test data set with the second Reference data set the authenticity of the tissue is checked.
  • both the test fabric, which examines its authenticity is to be, as well as the woven according to the inventive method Tissue is detected by measurement, for example, with an optical Scanner, camera or other suitable metrological Device, allowing a digital test record of the test tissue and a corresponding reference data set of the tissue can be created.
  • the means, the data sets are in the mathematical space of the tissue created and can be used in a suitable coordinate system Place space can also be displayed.
  • the aforementioned records are then loaded, for example, in a suitable data processing system and in each of these is preferred to a transformation into a positional space reciprocal space, for example by a one- or multi-dimensional Fourier transformation, in particular by the well-known fast Subjected to Fourier transformation into a reciprocal wave vector space.
  • a particular advantage of the inventive test method is especially in that even the smallest deviations in the test fabric of original fabric, which is in place, so the structure of a fake Test tissue itself are hardly or not detectable, in reciprocal space be detected in a simple manner and with great precision.
  • the reason for this is that even a small modulation of the basic structure, as the woven pattern can be interpreted in Wave vector space, or generally in a space reciprocal to the physical space, as additional intensities in the spectrum of the associated wave vectors to lead.
  • Test method to be examined pattern prefers no regular Structure, but can be generated, for example, that at the Control of the weaving machine in the weaving process certain parameters, for Example Control parameters in a computer program for control the weaving machine, more or less arbitrarily set, so that the Pattern has no regular structure but rather stochastic Character has.
  • This will change the pattern by applying the according to the invention, as it were provided with a "fingerprint", without knowing the special parameters for controlling the loom when weaving the pattern is practically not reproducible, so only by Use of the inventive test method, a test tissue, the possibly a fabric forgery is verifiable on authenticity.
  • a brand label 2 is shown schematically in each case as an example for a fabric 2 produced by the process according to the invention shown.
  • the brand label 2 may refer to a product glued, sewn on or in any other suitable manner to one Product be attached.
  • the brand label 2 has a characteristic Identification mark 21 on.
  • the identifier itself is preferred after woven in the inventive method in the brand label 2, can but also be connected in another way with the brand label 2.
  • the brand label 2 comprises a basic structure 3 into which a given pattern 4 is woven, the regular or may have stochastic character.
  • the cutout 22 is exemplary magnified in a coordinate system represented by the KS KS preferably orthogonal directions X and Y is clamped. It should be in the following the direction X, each defining the direction in which weaving the weft threads 5 are introduced while substantially along the Direction Y, the warp threads 6 run. These are for the sake of Clarity in FIGS. 1 to 4 in each case either only the warp threads 6 or the weft threads 5 shown. It is understood that the fabric 2 of course, in principle, both from warp threads 6 and from Weft threads 5 is constructed at the same time.
  • FIG. 1 schematically shows a fabric 2, here by way of example a brand label 2, represented, in which in a basic structure 3 of the fabric 2 thereby a Pattern 4 is woven during the weaving process, the strength of the Stop the sley from one weft 5 to another Weft 5 is slightly varied. This will make the distance between two Weft threads 5 in the fabric 2 varies, as shown in FIG. 1 can be clearly seen. The variation of the distance between two weft threads 5 is so slight that they are visible to the naked eye, ie without complex technical aids, in the Fabric 2 is not visible.
  • FIG. 2 another embodiment is shown schematically, in which the tension of the weft thread 5 when weaving after a given scheme is varied.
  • the middle one Distance between two weft threads 5 though over the entire fabric 2 in the remains substantially constant, but varies over the length of the shot in the direction X is the distance between two adjacent weft threads 5 locally, because the mechanical tension of the weft thread 5 over its length in the tissue 2 varied.
  • Fig. 3 was in analogy to the embodiment shown in Fig. 2 the tension of the warp threads 6 varies, which in the direction Y to a local Variation of the distance between two adjacent warp threads 6 leads.
  • One such Pattern 4 may be, for example, by a change in the opening angle during the shedding process during the weaving process according to a given scheme a technique known per se in weaving.
  • FIG. 4 shows an example of a fabric 2 in which the Control of a broad holder of the loom according to a predetermined Scheme was influenced.
  • a broad holder of the loom usually serves in a loom Wide holder to a constant width of the fabric 2 along the Y direction to ensure the warp threads 6 and thus their parallel course.
  • the width of the fabric 2 by suitable control of the Breithalter along the direction Y of the warp threads 6 to vary, so that again in the tissue 2 a deviation from a basic periodicity arises, which is clearly detectable in the reciprocal space.
  • FIGS. 5 and 6 each show the test method P according to the invention schematically explained in more detail.
  • FIG. 5 schematically shows a flow chart of a test method P and shows, by way of example, a brand label 2 produced according to the method according to the invention and a test fabric 200 which is examined for authenticity.
  • the test fabric 200 can not be distinguished from the genuine brand label 2 without technical aids with the eye.
  • the technical measuring device 7 which may be for example an optical scanner 7 or a camera 7
  • each of the tissue 2 and the test fabric 200 is a recording made, each in a digital test data set PD, which represents the test fabric 200 and in a digital reference data set RD representing the tissue 2 transferred.
  • the digital test data set PD and the digital reference data set RD are transformed by a transformation T, for example with a data processing system not shown here by means of a fast Fourier transform FFT, into the second reference data set RD -1 and the second test data set PD -1 , respectively Test fabric 200 and the tissue 2 in a reciprocal space, here in the wave vector space W represent.
  • a comparison is made between the second test data set PD -1 and the second reference data set RD -1 . This comparison can be made, for example, as shown schematically in Fig. 5 by appropriate subtraction of the two second data sets.
  • test fabric 200 is genuine, ie produced according to the method according to the invention. If the result data set E after a difference formation from the second reference data set RD -1 and the second test data set PD -1 is not empty, that is to say in a graphical representation of the result data set E in the wave vector space W, intensities still occur, as shown schematically in FIG the test fabric 200 is not produced by the process according to the invention and thus a forgery.
  • Fig. 6 is for clarification, the inventive test method P of Fig. 5 explained again with reference to a specific embodiment.
  • a section 22 of a Woven fabric 2 which is woven according to the inventive method was and deviates from an orthogonal regular basic structure Shows 3 different deviations, as shown in part with reference to FIGS. 1 to Fig. 4 have already been described in detail.

  • the Fourier spectrum of the test fabric 200 shows essentially only a single intensity I 0 of the undisturbed basic structure 3 in a narrowly defined wave vector range, as is also expected by the person skilled in the art for a regular structure of this type.
  • the Fourier spectrum of the woven fabric 2 woven according to the method according to the invention shows numerous other, more or less widely distributed intensities in other wave vector pairs. These additional intensities have their cause in the disturbances of the basic structure 3 of the fabric 2, which are clearly visible in FIG.
