The improvements relate to a thread (1) with an aluminium core (2) and a textile covering (3), the aluminium core (2) having a diameter of 51 to 1000 micrometres. Another improvement consists of said thread (1) being used as a covering for a textile fibre (4), of any length, for forming a rope (5) which can be used in the formation of fabrics for forming screened meshes for the insulation from electromagnetic waves in buildings.
The present invention, as it is stated in the title of this specification, relates to improvements made to the object of the patent of invention no.
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.
As it is known, due to technological developments, 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.
Thus, the Patent of Invention No.
Specifically, 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, polymethaphenilene isophthalamide and all their combinations and mixtures of them, where the aluminum core will have a section in line with the thickness of the coating, and said core can even be constituted through a mixture of aluminum with other materials, provided that the characteristics of attenuation and isolation from electromagnetic waves are maintained.
For its part, 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.
Likewise, it is worth highlighting that 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.
Ultimately, 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.
It has been shown that the aluminum core referred to can break in the coating phase, when being subjected to tension by the respective machine.
The improvements introduced in the main Patent of Invention referred to in the preceding paragraph, focuses on two fundamental aspects:
Based on the range of thickness or diameter referred to for the aluminum core of the thread, a certain mechanical strength according to the different applications is ensured.
Finally, say that the frequency range to be attenuated will be preferably comprised between 800 Hz and 12 GHz.
To complement the description that will be carried out in the following and with the object of helping to a better understanding of the features of the invention, the present specification is accompanied by a set of drawings based on which the innovations and advantages of the improvements object of the invention will be more easily understood.
As it can be seen in the figures referred to above, and specifically in
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
As it has been said, 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.
For its part, 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.
