Definitions

  • the invention relates to a method for producing the products specified in the preamble of claim 1.
  • the finished textile products are intended to cover the various textile surface products formed from such textile intermediate products, which can be produced in any way. These include, for example, woven fabrics, knitted fabrics, nonwovens or nonwovens.
  • the surface products can have any shape, for example as wide goods or as tapes, in particular Label, be formed.
  • white tones are sometimes used in addition to the dyes to increase the Brilliance of very light colors (pastel shades) in dyeing / printing formulations set.
  • Highly fluorescent stains can be made with fluorescent dyes the hues of yellow, orange, red, are generated because they are in the short-wave visible spectrum can absorb excitation energy, which is green, blue, Brown, gray, black is increasingly no longer the case due to self-absorption and so for physical reasons e.g. no fluorescent black exist can.
  • there is interest because e.g. the creation of Barcode markings based on a fluorescent contrast with all colored ones and achromatic colors must be possible if you want a universally applicable Establish marking procedures.
  • the whitener became superficial in one case upset. This attachment was not permanent. So already at textile processing of such yarns, e.g. when weaving, the superficial White tones can be damaged or removed by abrasion. If through that Incorporation of the yarn into the sheet product contained information that should be detected by a reader, this was no longer the case with abrasion possible. The information was damaged or destroyed.
  • the fiber was dyed through when the white toner was applied.
  • the fluorescence generated by UV light excitation in the Fiber has been absorbed, especially if it is fiber in dark colors traded, namely red, blue, green and especially black. A data acquisition a reader was not possible.
  • the invention has for its object a dark in all spectral ranges of visible light absorbing, preferably spun-dyed Yarn or textile surfaces subsequently by forming a fluorescent edge layer following the fiber circumference permanently and genuinely with intensive To provide fluorescent properties, but not the original appearance to change the hue of the color in daylight.
  • This is according to the invention achieved by the measure specified in the characterizing part of claim 1, to whom has the following special meaning.
  • the white toner in the invention is in a ring zone down to a deeper one Layer, it is protected towards the fiber surface and is therefore resistant to abrasion.
  • the White toner preferably takes up only 15% of the available fiber cross section. The The remaining cross section is free of this. Even if the product is in very dark tones trained, e.g. the color is black, the fluorescent radiation not wiped out. It shines through the thin, separated from the fiber surface Layer to the outside with sufficient intensity. This radiation can come from one Data acquisition device can be read.
  • Invisible marking of objects with fluorescent supports serve among other things to identify the authenticity, the origin, the Quality. They should be as long and global as possible with devices for data acquisition be readable. Barcodes, consisting of e.g. textile threads or Printing on textile surfaces with and without fluorescence, combined with everyone any bright and achromatic color that is firmly attached to the object and at the same time with visible signs e.g. Can be an advertising medium. The marketability of the process depends largely on whether the barcode marking also on dark colored articles e.g. Sewn-in labels let it be realized or not. Also differently shaped markings on this principle of contrast formation by using fluorescent Threads in the manufacturing process of textiles are suitable for identification.
  • any existing spin finishes are replaced by a Alkali treatment at 110 ° C removed from the yarn.
  • This treatment continues to be used Roughening and chemical modification of the fiber surface of the polyester yarn due to the fact that it starts from the fiber surface Ester cleavage, which must be controlled so that a weight loss of at most 1% occurs. Rinsing and changing the bath removes the detached one Spin preparation and neutralizes the liquor pH.
  • a commercially available dispersion whitener is used preferably based on a disteryl-biphenyl derivative without Sulfo groups, applied in a concentration of 0.5% of the material weight, the liquor pH is acidic (pH 4.0; methanoic acid) and the Heating rate from 25 ° C to 95 ° C 4 ° / minute and further from 100 ° to 130 ° C 1 ° / minute is.
  • the treatment time at 130 ° C is no longer than 10 minutes.
  • the criterion for the end of treatment is the time of disappearance the fluorescence in the treatment bath, which is indicated by ongoing assessment of time-proportional fleet samples under UV light is determined.
  • polyester filament yarn e.g. black spun-dyed yarn, fineness 76/24 dtex
  • perforated dye tubes optimal tension spooled and in the laboratory cross-dyeing machine (Celtex-Colorstar CS-2 with date program control, flow rate 1 L / minute, Differential pressure 0.4 bar, flow direction change every 2 minutes)
  • any existing spin finishes are replaced by a Alkali treatment at 110 ° C removed from the yarn.
  • This treatment continues to be used Roughening and chemical modification of the fiber surface of the polyester yarn due to the fact that it starts from the fiber surface Ester cleavage, which must be controlled so that a weight loss of at most 1% occurs.
  • Rinsing and changing the bath removes the detached one Spin finish and restores the liquors - pH neutral.
  • a commercially available dispersion whitener is used preferably based on a disteryl-biphenyl derivative without Sulfo groups, in a concentration of 0.5% of the material weight and one fluorescent dispersion yellow dye based on naphthalimide derivatives applied, the liquor pH slightly acidic (pH 4.5 to 5; methanoic acid) is set and 1 g / L dyeing accelerator based on methyl cresotate is added.
  • the heating rate is from 25 ° C to 95 ° C 4 ° / min and from 100 ° to 106 ° C 1 ° / min.
  • the treatment time at 106 ° C is generally no longer than 10 to 15 minutes, the criterion for the end of treatment being the time of the Disappearance of the fluorescence in the treatment bath through ongoing assessment of time-proportional fleet samples under UV light. Execution of the Avoid cross-section of fibers. After cooling and rinsing the material If necessary, a finishing agent is applied, the type and amount of which must be chosen that no fluorescence reduction and a flawless Weaving process is enabled.
  • Woven textile surfaces with basis weights of 50 to 120 g / m 2 made of polyester material are pretreated alkaline, analogously to Examples 1 and 2, then dyed with disperse dyes in dark colors according to a conventional block thermosol process, the dyeing liquor having a stiffening effect, if necessary washable agent, for example based on carboxymethyl cellulose, is added.
  • the surface coloring is initially not fixed, only dried.
  • the stiffened textile surface is printed with a pattern generated by the software using an ink jet printer (eg PC-Jet printer HP690).
  • the ink cartridge is filled with a special preparation consisting of a white toner and a solvent, such as polyamine alcohol.
  • the coloring and printing are fixed together by heat treatment with hot air at a maximum of 150 ° C for 1 minute.
  • Fig. 1 of the drawings shows, in large enlargement, a cross section through some capillary fibers 10 of a multifilament made of polyester. It deals a spun-dyed, preferably black fiber. How through that Hatching clarifies, the fiber has a dark color 11.
  • FIG. 3 shows the graphic representation of the dispersion whitener used according to example 1.
  • On the abscissa is the wavelength of the visible Light given in nanometers (nm).
  • On the ordinate is the light reflections black dyes applied, each with a white tint or additional added to the white toner with fluorescent dyes, with UV radiation Retroreflect visible light enriched with fluorescent light at different intensities.
  • Four curves 20 to 23 are shown by different symbols illustrate different behavior of the fluorescent materials.
  • the curve 20 shows the fluorescent light of a white toner without its own color on one black base color in a concentration of 0.5%, based on the Fiber weight.
  • Curves 21, 22 and 23 show the corresponding ratios when looking at the Substance according to curve 20 still fluorescent dyes in a concentration of 0.1%.
  • Curve 21 shows a red fluorescent dye.
  • the Curve 22 also shows a red dye with a slight difference compared to FIG. 21 lower intensity.
  • Curve 23 illustrates the relationships when to the substance from curve 20 a yellow fluorescent dye is added. The areas below the curves show the strength of the fluorescence.
