Definitions

  • the invention relates to a coding for the purpose of textile, such as knit fabrics and woven fabrics, and non wovens, wherein the coding comprises a number of dots of ink, wherein the presence or absence of any of the ink dots indicates a particular code.
  • the invention also relates to a method for applying and detecting such coding.
  • EP-A-0 328 226 discloses a coding for the purpose of textile, and a method and apparatus for applying such coding.
  • the coding is detectable by means of electromagnetic induction resulting from the fact that the coding is built up from dots of iron-containing dye or adhesive.
  • iron-containing dye or adhesive has the particularly great drawback that during a bleaching treatment of the textile, the iron brings about a catalytic reaction causing damage to the material. This damage can consist of weakening of the fibers and can even lead to the formation of holes in the material. This drawback is also inherent in other substances to be detected on the basis of induction, such as copper, nickel, cobalt, manganese and aluminum.
  • the textile web is provided with a sticker provided with an optically readable code.
  • coding itself is damaged when the textile web is bleached, as a consequence of which, after bleaching, the ceding is no longer readable.
  • dying or printing the textile web is not possible, because this results in the coding becoming unreadable.
  • the sticker causes a local thickening, which complicates processing operations such as calendering.
  • the object of the invention is to provide a coding for textile and/or non wovens of the type mentioned in the opening paragraph, without the above-described drawbacks.
  • the coding of the type mentioned in the opening paragraph is characterized in that the ink is of a highly quick-drying type, and is detectable even when the code is no longer visible due to the fact that the material has undergone a dying treatment or has been printed, with the ink or substances contained in that ink not entering into a catalytic reaction during the different treatments which the material undergoes during the production process.
  • the major advantage of the coding according to the invention is that ink does not enter into a catalytic reaction during the different treatments which the material undergoes during the production process. Hence, the material retains the same quality everywhere, also at the location of the coding.
  • precious metals are incorporated into the ink for the detectability thereof.
  • Some precious metals such as for instance silver, are electrically conductive and can hence influence an electromagnetic field, so that they are detectable by means of electromagnetic induction.
  • Other precious metals that are not electrically conductive can in fact reflect or block microwaves, so that they are detectable by means of a microwave source/detector assembly.
  • Suitable precious metals are for instance silver, platinum and gold.
  • metal ions can be incorporated into the ink for 4
  • the detectability which metal ions by themselves have catalytic action during the treatment processes, wherein the catalytic action is however undone due to the fact that the metal ions are bonded in metal complexes or alloys or in a crystalline structure, so that no ions can be released during chemical reactions .
  • the particles present in the ink for the purpose of detection can be closed off with a protective layer of, for instance, synthetic material.
  • a protective layer of, for instance, synthetic material for instance, synthetic material.
  • toner for copiers wherein the carbon particles are enclosed by a binder material.
  • enclosed particles cannot enter into a catalytic reaction either during the treatment process.
  • Inks of the above-mentioned type are indeed detectable without being visible, while the substances contained in the ink do not result in catalytic reactions during, in particular, the bleaching treatment of the material.
  • the invention also relates to a method for applying the coding according to the invention to a material web of textile and/or non wovens .
  • the method is characterized in that a roll moves over a matrix of a number of inking pins movable into a first and a second position, so that a desired pattern of ink dots is transferred onto the roll, wherein the roll is then rolled along the material web, so that the ink dot pattern is transferred onto the material web.
  • the invention also relates to a method for detecting a coding according to the invention applied to a material web, wherein a microwave source transmits microwaves to the material web at a position where the coding is applied, wherein the material web is moved along a number of microwave detectors in such a manner that the coding passes these microwave sensors, so that the microwaves reflected by the applied ink dots are detected by the microwave detectors, wherein a processing unit processes the signals provided by the microwave detectors and determines the coding.
  • microwave sensors can also be arranged on the side of the material web facing away from the microwave source. In that case, the detection takes place in that the blocking of microwaves is detected rather than the reflection of microwaves.
  • the invention also relates to an ink intended for applying a coding according to invention and to the use of such ink as coding.
  • Fig. 1 shows an exemplary embodiment of a possible coding
  • Fig. 2 schematically shows an apparatus by means of which the method for applying the coding can be carried out, wherein in particular at step two, the textile web is shown on a reduced scale relative to the application roll.
  • the exemplary embodiment shown in Fig. 1 of a coding for the purpose of textile or non wovens comprises a number of ink dots P, with the presence and/or absence of any of the ink dots P indicating a specific cede.
  • the ink is of a highly quick-drying type and is detectable even when the code is no longer visible on account to the fact that the material has undergone a dying treatment or has been printed, because the ink contains a substance that reflects or blocks microwaves. Moreover, the ink or substances contained in that ink do not enter into a catalytic reaction during the different treatments which the material undergoes during the production process.
