Another object is to provide a thread which comprises a composition as above and is particularly adapted to produce articles characterized by high visibility in conditions of poor or no lighting and in the absence of external light sources. Another object is to provide a thread as described above which is also characterized by combustion-retardant properties, antibacterial or antiodorant properties, is inalterable over time, is environmentally compatible and is easy and cheap to manufacture and work.
  • a further object is to provide a method for preparing a thread starting from a composition as described above.
  • compositions particularly for manufacturing threads, which comprises polypropylene and at least one luminescent material.
  • the aim and objects of the invention are also achieved by a thread which can be obtained from a composition as described above.
  • the aim and objects of the invention are also achieved by a method for manufacturing a thread which comprises a composition defined as above, wherein the method comprises the step of incorporating at least one luminescent material within polymeric cells of polypropylene.
  • the invention relates to a composition which comprises polypropylene and at least one luminescent substance, such luminescent substance being advantageously in a quantity comprised between 1% and 40%, preferably between 10% and 20%, even more preferably equal to 15% by weight on the total weight of the composition.
  • luminescence is used here to designate the phenomena of phosphorescence, fluorescence or chemiluminescence, preferably phosphorescence.
  • the expression "luminescent substance” is used to designate any substance characterized by an electron structure such that the absorption of photons by said substance leads to an emission of radiation in the visible spectrum which lasts over time, preferably as a consequence of a phosphorescence phenomena.
  • said at least one luminescent material is selected from the group that consists of phosphorus and compounds which belong to the family of aluminate oxides of alkaline earth metals doped with europium. These compounds are per se known.
  • aluminate oxides of alkaline earth metals doped with europium is used to designate luminescent compounds which substantially comprise oxides of alkaline earth metals and alumina (Al 2 O 3 ), doped with europium.
  • the luminescent compounds used also comprise boron oxide (B 2 O 3 ).
  • doping occurs with a combination of europium and dysprosium.
  • composition can comprise advantageously also one or more optional ingredients selected from the group which comprises colors, pigments, fire-resistant substances, such as for example antimony trioxide, antibacterial substances, and mixtures thereof.

  • a second aspect of the invention is constituted by a thread characterized by great visibility even in complete darkness, which can be manufactured for example by extruding a composition as defined above.
  • the luminescence entails the necessary exposure of the composition, of the thread or, more advantageously, of the article manufactured with the thread to an external light source during the period in which they are not used, and can last up to three hours after the end of the exposure.
  • the luminescence is due to the presence of the at least one luminescent substance, which is capable of absorbing photons in a broad range of wavelengths and of reemitting the energy in the form of a radiation in the visible range for a period which follows the end of the exposure to the external light source. Accordingly, the high- visibility effect is obtained even in the absence of a light source.
  • the solution constituted by the invention differs distinctly from the threads used up to now for similar purposes, which do not emit, but are exclusively capable of reflecting, light that arrives from an external source (headlights of a vehicle or others).
  • the thread according to the invention is employed usefully wherever it is desirable or advantageous to have luminescent articles, such as for example in the manufacture of items of clothing, preferably for safety workers. However, it is also possible to use the thread according to the invention to manufacture fabrics for curtains, fabrics for interior decoration, for producing night-time special effects, fishing nets, ropes and others.
  • the thread of the invention can also be usefully employed in the manufacture of unique-identifiers for instance for clothing or other goods.
  • a manufacturer of items of clothing could for example insert a length of the thread of the invention within the fabric so as to identify its items and distinguish them from similar items manufactured by others.
  • This use can also be advantageous for the identification of commercial counterfeitings as products lacking the unique-identifier made with the luminescent thread of the invention would be immediately and unambiguously identified.
  • the thread according to the invention has many other advantages, including the inalterability of its characteristics over time, the property of being slow-burning or flame retardant, and of being workable by means of the most widespread technologies for the ordinary working of threads. It is further possible to give the thread the most desired coloring by simply embedding inside it pigments and colors or to give it antibacterial and antiodorant characteristics.
  • the polypropylene thread according to the present invention is perfectly environmentally compatible, since it does not lose into the environment any luminescent substance and does not entail the emission of harmful or polluting radiation.
  • the invention relates to the production of a thread starting from a composition as defined above which is based on polypropylene and at least one luminescent substance, said method comprising substantially the step of incorporating the at least one luminescent substance within polymeric cells of polypropylene.
  • the method according to the present invention can be performed with conventional machines for manufacturing polypropylene threads.
  • Such machines provided with extruders and spinners, allow to manufacture a thread with the required characteristics. It is particularly preferable for extrusion through a spinneret to occur with a denier-filament value which is higher than conventional values and in particular is comprised between 10 and 30.
  • a denier-filament value which is higher than conventional values and in particular is comprised between 10 and 30.
  • the number of holes of the spinnerets used within the method is comprised between 1 and 40.

  • master advantageously comprises granules (or cells) of one or more materials selected from the group which comprises neutral propylene, polyethylene, preferably low-density polyethylene, granules of polypropylene incorporating various elements (color, pigments, fire-retardant material, antibacterial products) and mixtures thereof.
  • the master receives the addition, in a step which follows feeding to the machines but before extrusion, of the at least one luminescent substance in the quantities described above. As a consequence of the extrusion, the luminescent material is incorporated within the polypropylene cells.
  • the invention relates to an article which comprises a thread as defined above.
  • a fabric manufactured with luminescent thread can be used to produce bands to be applied to items of sports clothing, in order to make the athlete visible even with poor ambient lighting.
  • a luminescent white thread can be used to produce deep-sea fishing nets; the fish is attracted by the luminescence of the article and is trapped by it.
  • a luminescent white thread can be used to produce cables for mooring watercraft in ports; in this manner, in case of night-time mooring it is always possible to find the ropes even if they are immersed in the water.
  • Shoelaces or items of clothing manufactured or woven with said thread can produce interesting effects in discos or in the presence of black light.

Abstract

L'invention concerne une composition luminescente contenant du polypropylène, un procédé permettant de produire un fil ou un monofilaments à partir de cette composition, et un article comprenant ce fil et convenant particulièrement pour la fabrication de tissus destinés à la confection de vêtements et d'uniformes ainsi que de rideaux et de tissus de décoration d'intérieur, de filets et de cordages. La composition décrite est capable de se charger de lumière pendant la journée, ou chaque fois qu'elle est exposée à une source lumineuse adéquate, et de libérer cette luminescence dans l'obscurité pendant une durée considérable.
