Definitions

  • the present invention relates to improvements made to the object of the patent of invention no. 200702449 , which describes a thread for fabric with attenuation and insulation capabilities against electromagnetic waves, applicable preferentially and mainly in the construction of apparel items, civil, military and industrial, as well as for coatings that have as an objective to attenuate and isolate electromagnetic waves.
  • the object of the invention is to achieve an optimal resistance of the thread and to be able to use it to make a fabric that allows, not only attenuating and isolating the human being from radio frequency radiation that is undergoing daily, but also to make fabrics capable of forming an electromagnetic waves insulating element in buildings.
  • the human being is daily undergoing constant electromagnetic radiation due to the radio frequency waves that are created by mobile phones, appliances, scanners, radars, relays of all types of signals, safety devices, frequency inhibitors, alarms, satellites, aerial and underground electric wiring, etc., i.e. any emitter of radio waves, either by its own motivation, either by emissions that accompany its functioning, causing as primary effect a warming of the elements they cross due to the dispersal of its energy, as it is the case of the human body, and that has caused social alarm because of the possible diseases of all kinds, as well as psychical and physical alterations these can produce.
  • Patent of Invention No. 200702449 describes a thread for fabrics with attenuation and insulation capabilities against electromagnetic waves, where the fabrics are likely to be used for manufacture of apparel items or industrial fabrics that allow to isolate, partially or totally, the user or objects from the radiation to which they are subjected nowadays, as a result of the electric and electronic technologies used for multiple purposes in society.
  • the thread for fabric with attenuation and insulation capabilities against electromagnetic waves described in this main Patent of Invention is comprised of an aluminum core or any material that has the same features at the level of attenuation and insulation of electromagnetic waves, and a textile coating which can be made of: cotton, silk, viscose, viscose FR (flame retardant), acrylic, methacrylic, wool, wool FR, melamine, polypropylene, polyethylene, ultra high molecular weight polyethylene, low density polyethylene, high density polyethylene, high density polyethylene polyamide, polyamide HT, fire retardant polyamide, polyester, polyester HT, fire-retardant polyester, polyester copolymers, aromatic polyamides (meta-aramid and para-aramid) and their copolymers (copolyaramid), polyacrylonitrile, polybenzimidazole, polyphenylene 2,6-benzobisoxazole, polyphenylene terathalamid, polyvinyl, polyamide, polyetherimide, polyamideimide
  • the coating of the materials listed above will be based on braided or even twisted sub-threads, being able to use as a coating any other type of natural or synthetic thread, as present in the market, current or future.
  • the rope formed by the braided or twisted sub-threads, constituting the coating of the aluminum core can be monofilament or multifilament, and intervenes in a number of three, four or five to form the coating in each case.
  • the thread for fabric with attenuation and insulation capabilities against electromagnetic waves envisaged in that main Patent of Invention is based on adhering, by any physical or chemical process, a coating on an aluminum core or mixture of it with other appropriate materials, where the coating can be of any type of fiber, allowing the finished spinning to cross creating weft and warp to ultimately configure a fabric that allows the manufacture of apparel items or industrial fabrics, which will enable to partially or totally isolate the user or element from radio frequency electromagnetic radiation to which it is constantly subjected, and solving with it, or at least alleviating in good part, the exposure to said electromagnetic waves and thereby the consequences or possible consequences thereof.
  • the frequency range to be attenuated will be preferably comprised between 800 Hz and 12 GHz.
  • the aluminum core 2 will be constituted by a filament the section of which shall be comprised between 51 and 1000 microns, while the textile coating 3 of said core 2 shall consist of sub-threads which can be braided or twisted in a surrounding manner on the core 2.
  • the textile fiber 4 on which the thread 1 is applied in a surrounding manner may be short or long, and the implementation of such thread can be single spiral-shaped as shown in figure 1 , to obtain a rope 5, or else using two threads 1 arranged braided as depicted in figure 2 , to obtain a rope 5'.
  • the aluminum core 2 of the thread 1 rather than a strand of pure aluminum, can be made up of a mixture with other metallic materials, provided that these do not exceed 50% of the total of the composition of the aluminum core 2, allowing obtaining fabrics with the maximum performance.
  • the coating 3 can be formed by braided or twisted threads, with simple or multiple fibers, and rather than being made of any of the materials referred to in the "background of the invention section" they may be or also be constituted on the basis of other textile materials, i.e., any other type of spinning, both natural and synthetic.
