Definitions

  • the present invention is referred to a thread for cloth able to attenuate, and insulate from, electromagnetic waves, preferably and fundamentally applicable in producing wearing apparel, such as civil, military and industrial, as well as for coverings with the purpose of attenuating and insulating electromagnetic waves.
  • the object of the invention is to create a thread to make a cloth allowing attenuating and insulating a person, among others, from the radiation caused by radiofrequency and to which they are subjected daily.
  • the thread for cloth able to attenuate, and insulate from, electromagnetic waves that is referred to, is designed to prepare cloths that may be utilized to prepare wearing apparel or industrial cloths allowing to insulate, partially or totally, the user or object from the radiations to which they are subjected nowadays, as a consequence of the electrical and electronic technologies utilized for multiple purposes in the society.
  • the thread for cloth able to attenuate, and insulate from, electromagnetic waves of the invention is characterized in that it consists of an aluminum core (or another material in the absence of aluminum, having the same characteristics at the level of attenuation and insulation from electromagnetic waves) and a covering made of any of the following matters: cotton, silk, viscose, viscose FR (flame retardant), acrylic, modacrylic, wool, wool Fr melamine, polypropylene, polyethylene, ultra-high molecular weight polyethylene (UHMWPE), low density polyethylene (LDPE), high density polyethylene (HDPE), high density polyethylene (HDPE) polyamide, polyamide HT, fire-resistant polyamide, polyester, polyester HT, fire resistant polyester, polyester copolymers, aromatic polyamides (meta-aramids and para-aramids) and copolymers
  • copolyaramides thereof, polyacrylonitriles, polybenzimidazole (PBI), polyphenylene 2,6-henzobisoxazole (PBO), polyphenylene terephthalamide (PPTA), polyvinyls, polyimide (PI) polyetherimide, polyamide-imide (PAI), poly-meta-phenylene isophthalamide (MPD-I), carbon fiber or thread, and all their combinations and mixtures, wherein the aluminum core (or another material in the absence of aluminum) will have a section according to the covering thickness, said core can even consist of aluminum mixed with other materials, as long as the attenuation and insulation characteristics are maintained with respect to electromagnetic waves.
  • the aluminum can also be totally or partially covered with carbon fiber or thread.
  • the covering of the mentioned matters will be based on plaited and/or twisted sub-threads, being able to utilize as covering any other type of natural or synthetic yarn, commercially available, currently or in the future.
  • the plaited thread end (plaited sub-threads) and/or twisted thread end, making up the covering of the aluminum core (or another material in the absence of aluminum), can be a monofilament or multi-filament, and intervening in numbers of 1, 2, 3, 4 or 5 in order to form the covering in each case, wherein said thread end may be single or multi-stranded; and in case of it being two thread ends, these will be crossed, plaited or twisted.
  • the arrangement of the thread obtained in the cloth will always form a grid with vertical and horizontal segments, thus securing the attenuation of the vertically and horizontally polarized waves.
  • two normal threads can alternate with the threads of the invention, all as a function of the wavelengths to be attenuated, which is a function of the separation between the threads.
  • the thread for cloth able to attenuate and insulate from, electromagnetic waves, object of the invention is based on adhering by any physical or chemical procedure, a covering over an aluminum core (or another material in the absence of aluminum), wherein the covering may be made of any fiber type, including, for example, carbon fiber or thread, allowing the finished spinning to cross or twist, creating weft and warp in order to finally configure a cloth which allows the preparation of wearing apparel or industrial cloths, which can make it possible to partially or totally insulate the user or element from the electromagnetic radiation caused by radiofrequency to which they are subjected constantly, as discussed in the section "background of the invention", and thus solving, or at least largely palliating, the exposition to said electromagnetic waves and thus to the consequences or possible consequences thereof.
  • the thread for cloth able to attenuate, and insulate from, electromagnetic waves, object of the invention, of an aluminum core 1 (or another material in the absence of aluminum), formed by a filament of appropriate section and a covering based on plaited sub-threads 2 made of the aforementioned matters.
  • three plaited sub-threads 2 can be observed Constituting the covering 3 of the aluminum core 1.
  • figure 2 shows an aluminum core 1' (or another material in the absence of aluminum) with a covering 3' formed by four plaited sub-threads 2'.
  • Figure 3 shows an aluminum corc 1" (or another material in the absence of aluminum), with a covering 3" formed by five plaited sub-threads 2".
  • the aluminum core 1 or 1' or I" (or another material in the absence of aluminum), instead of being made of a pure aluminum filament, it can consist of a mixture with other metallic materials, as long as these do not exceed 50% of the total core composition, hallowing to obtain cloths with the maximum performance.
  • the plaited threads 2 or 2' or 2" can be single or multi-stranded, and instead of being made of cotton, silk, viscose, viscose FR (flame retardant), acrylic, modacrylic, wool, wool Fr melamine, polypropylene, polyethylene, ultra-high molecular weight polyethylene (UHMWPE), low density polyethylene (LDPE), high density polyethylene (HDPE), high density polyethylene (HDPE) polyamide, polyamide HT, fire-resistant polyamide, polyester, polyester HT, fire-resistant polyester, polyester copolymers, aromatic polyamides (meta-aramids and para-aramids) and their copolymers (copolyaramides), polyacrylonitriles, polybenzimidazole (PBI), polyphenylene 2,6-benzobisoxazole (PBO), polyphenylene terephthalamide (PPTA), polyvinyls, polyimide (PI) polyetherimide, polyamide-imide (PAI), poly-
  • FIG 4 a thread is shown wherein the corresponding covering 3 " ' of the aluminum core 1 " ' consists of only one thread end or helicoidally rolled sub-thread 2"' which may be single or multi-stranded.
  • FIG 5 a thread is shown wherein the corresponding covering 3"" of the aluminum core 1"" consist of two thread ends or sub-threads 2"", crossed or twisted, made of only one filament or multi-filament.
  • the arrangement of the thread will always form a grid with vertical segments 4 and horizontal segments 4', as shown in figure 6 , such that that grid arrangement ensures the attenuation of the polarized waves vertically and horizontally.
  • the cloth warp it may be formed by normal threads 5-5' alternated with the threads 4-4' of the invention, depending on the wavelengths to attenuate, which depends on the separation between the threads 4-4'.
