Definitions

  • the present invention concerns a safety yarn that may be applied for preventing counterfeits and falsifications into the seams and decorations of documents, like passports and similar, and of leather goods and clothing, of the kind becoming luminescent if exposed to light sources like ultraviolet Wood lamps, and the realization process thereof.
  • the aim is reached, according to the present invention, by means of a yarn of the synthetic kind like polyamide, polyester and similar, raw or dyed and lubricated with silicone mixtures, or by means of a yarn of a cotton-synthetic mixture, raw or dyed and polished, satined or glazed by means of flours, grease, wax, paraffin-oil, silicon so as to eliminate all down which is always present in cotton, which is passed, according to the process, through a liquid homogeneous mixture of pure pigment with solvents, so as to become luminescent and remarkable in a colour shade, if exposed to the Wood lamp, different from the optical one.
  • the main advantage of the yarn obtained by means of the process according to the present invention consists in that the determined shade may be perfectly seen, under the Wood lamp, without any difference of shade in the chosen colour, so as to prevent any counterfeit to the documents and the goods to which it will be applied.
  • the present invention will be described more in detail hereinbelow referring to the enclosed drawing in which a vertical scheme is shown of the means used for the realization process of the yarn according to the present invention.
  • the figure shows the means and the sequence of the realization phases for obtaining a safety yarn for preventing counterfeits and falsifications of documents and leather goods and clothing, characterized in:
  • a small basin 2 having the shape of a half cylinder, fed with constant quantities of a mixture of ink and solvent by means of a drop proportioning device 3 with adjustable flow, and containing an electrically operated first steel roll 4 under which passes said yarn F in its obliged way, getting completely immersed into said small basin 2;
  • the process will be completed by the electronic precision meter counter 12, by means of which the chosen length, according to the kind and thickness of the yarn F used, may be programmed, and by the controll 13 of the oil level in the operating machine.
