  • Luminescent cellulosic regenerated fiber and process for its preparation
  • the invention relates to a luminescent cellulosic Regeneratmaschine with at least one spun pigment, a process for their preparation and the use of this luminescent cellulosic Regeneratmaschine.
  • HiVis textiles are primarily made from synthetic fibers, with spun-dyed polyester yarns playing a dominant role in the market.
  • the extremely low moisture absorption of polyester ( ⁇ 0.5%) usually leads to a low wearing comfort.
  • a complex textile construction comprising a plurality of fibers having a synergistic effect is developed. Since synthetic fibers generally have the latent danger of electrostatic charging, and thus a high safety risk can arise for the wearer, alternatives to HiVis polyesters have also been sought.
  • HiVis cotton to call based on the natural fiber cotton, which can be prepared by conventional dyeing methods with suitable fluorescent dyes.
  • This fiber has almost no electrostatic properties and is also characterized by good wearing comfort.
  • the production process of HiVis cotton is not only very cost-intensive, but, like any bath dyeing process, it is extremely polluting.
  • the color fastness is very difficult to achieve and the mechanical strength of 100% cotton yarns, and in particular the resistance to friction and tear, is not all that high.
  • a hitherto available possibility to obtain a fluorescent cellulosic regenerated fiber meeting the EN 471 standard is a two-stage process described in WO2011 / 032191, which represents a serial combination of spinning and bath dyeing.
  • a cellulosic regenerated fiber is spin-dyed with a color pigment (yellow).
  • the fiber is over-dyed with a fluorescent dye in order to comply with the requirement of standard EN 471 and in particular the light fastness according to ISO 105-B02.
  • Light fastness describes the constancy of paints and varnishes and takes account of the fact that sunlight with high UV content can have a "decomposing" effect on materials
  • the standard EN 471 stipulates a test procedure with xenon irradiation for the light fastness of yellow materials , where "the exposure shall be made until the change of the comparison scale number 4 of the blue scale corresponds to level 4 of the gray scale". Furthermore, the standard requires that after this irradiation z. B. the minimum luminance factor of the yellow material must be greater than or equal to 0.7 and the color value components are within the range specified for the color.
  • luminance factor the skilled person understands the ratio of the luminance of a screen sample to the luminance of a completely scattering and reflecting surface. Such a surface is also called white standard.
  • the object of the invention is to provide a luminescent cellulosic regenerated fiber which is improved in terms of its suitability for protective equipment and its manufacturability.
  • the invention is also based on the object of specifying a method for producing this cellulosic regenerated fiber, in particular of a multifilament yarn, and to indicate its use.
  • this object is achieved in terms of Regeneratfaser characterized in that the spun pigment is a luminescent pigment and the fiber additionally contains a spun matting pigment.
  • the task solution consists in that the admixed pigment is a luminescent pigment and, in addition, a matting pigment is admixed.
  • the regenerated fiber according to the invention can thus be obtained in a single process step of spin-dyeing a suitable viscose with a dispersion of the luminescent pigment and the matting pigment.
  • the luminescent pigment may be an organic luminescent pigment.
  • the z. B. is a white pigment, it can each be commercially available products.
  • the regenerated fiber according to the invention it is possible to meet the standards applicable to protective and warning clothing, in particular the requirements according to EN 471. It is a tensile strength of at least 3 cN / tex, preferably at least 0cN / tex, achievable.

  • textile fabrics with abrasion resistance according to Martindale (9 kPa) of at least 20,000 turns, preferably of 45,000 turns and more preferably of 70,000 turns can be achieved.
  • the regenerated fiber according to the invention may contain further additives, but the total pigment content of the fiber should be at most 28%, preferably at most 25%.
  • the regenerated fiber is flame retardant and meets the applicable standards for protective clothing.
  • the LOI value is at least 24, in particular at least 26.
  • the luminescent pigment is preferably a fluorescent pigment.
  • phosphorescent pigments differ in that the latter luminesce after exposure to radiation in the dark. In particular, in product protection, this property can be used by the afterglow after irradiation with z.
  • UV light is used as a test criterion / authenticity criterion.
  • the cellulosic regenerated fiber is hydrophobing-equipped.
  • the hydrophobing can be achieved by substances known to the person skilled in the art, in particular fluorohydrocarbons, and processes. As a result, not only a water but also a dirt-repellent effect can be achieved. The latter is particularly desirable for applications in the upper area.

  • aqueous dispersion of a commercially available luminescent pigment and a matting agent, for example titanium dioxide is previously stirred in a suitable container in order to achieve a uniform distribution of the water-insoluble pigments.
  • the quality of the pigment dispersion which is determined by the average and maximum particle size, has a significant influence on the fiber properties.
  • the maximum particle size with suitable dispersants is preferably below 10 ⁇ m, in particular below 5 ⁇ m.
  • This dispersion is subjected to a filtering operation prior to addition to the dissolved cellulose in which particles larger than 25 ⁇ m in size are retained.
  • concentration of the cellulose is preferably 5 to 8% with an ⁇ -cellulose content of at least 98%, preferably of at least 97.5%.
  • a flow of the dispersion is added to a flow of cellulose in a fixed ratio.
  • Static or dynamic mixers in the total stream ensure the required homogenization of the dispersion in the viscose matrix, whereby the contact time of the pigments with the basic viscose is to be adjusted until the chemical resistance of the pigment is sintered.
  • the strength of the yarn can still be influenced, for example by the withdrawal speed, the stretching and the composition and temperature of the spinning bath.
  • a 2-bathiges spinning process is used, wherein the acid concentration in the drawing bath compared to the coagulation bath is in particular 28 to 30% lower.
  • the EN 471 standard is only fulfilled if its solids content in the finished fiber is at least 0.6% and a matting agent is added. Preferably, this solids content is adjusted to values between 0.8 and 2%, in particular between • 1.0 and 8%.
