TECHNICAL ASSISTANCE AND EXPLANATIONS.

This protective clothing against electromagnetic waves for people who are sensitive to electricity or electrosensitive is made from different fabrics. There are no good or bad fabrics, only fabrics that are suited to specific needs. The global market distinguishes between two main categories: - EXPOSED METAL FABRIC: All types of fabric in which the metal (silver/copper/stainless steel/nickel/etc.) is said to be "exposed", meaning that it is in direct contact with the air or its surrounding environment. Oxidation can occur at varying speeds depending on the level of humidity (breathing in a canopy, for example), and above all on the quality of the metal used and the manufacturing processes it has undergone. As their meshes are conductive, they have the advantage of being able to be earthed (via a conductive wire) to allow direct discharge of the electronic charges received. Some people misleadingly and falsely claim that they protect against low frequencies. Unfortunately, this is not the case and depends EXCLUSIVELY on how they are used and installed. Please consult us for more information. Under no circumstances will a fabric that is too often advertised as "protecting against low frequencies" protect against low-frequency magnetic fields from electricity... We certify this technical statement as legally binding. And in many cases, depending on how they are used and installed, they do not protect against low-frequency electric fields either... even if an electric field meter (such as the ME3030B GIGAHERTZ or a higher-end model, for example) reads 0 volts... Please consult us for the physical explanation behind this reality of physics, which we certify as legally enforceable. - METAL FABRIC COATED in PLASTIC SHEATHING or sometimes referred to as BIOCOMPATIBLE Fabrics manufactured in SWITZERLAND under the SWISS SHIELD or SWISS brand... which have their metal threads coated in plastic referred to as "biocompatible" by people who are chemically sensitive / MCS Multiple Chemical Sensitive in polyurethane or polyester or conductive carbon polyester. This category has many advantages, first and foremost its very long life, particularly in terms of metal oxidation (except for stainless steel), and secondly the "elimination" of possible metal particles pressed against the fabric fibres (known as BARE METAL FABRIC) which could become detached over time, particularly after washing. Furthermore, it is accepted by the scientific and medical community that oxidised fabrics can be toxic if volatile particles that may detach from the fabric are inhaled or come into contact with the skin (undesirable metals present in organs being a primary AND major cause of Electromagnetic Hypersensitivity (EHS) / Microwave Syndrome and Chemical Sensitivity (MCS)). Metal fabrics encased in a plastic sheath will therefore not have these disadvantages. o Swiss-made fabrics with a carbon polyester sheath will have conductive meshes, allowing (like BARE METAL FABRICS) electronic charges to be discharged immediately to earth by conductivity via an earthing wire. This allows for zero electric field measurement in such cases. Field protection o SWISS-made fabrics with a polyester or polyurethane (non-carbon) sheath will have non-conductive meshes, allowing (like BARE METAL FABRICS) electronic charges to be immediately discharged to earth by conductivity via an earth wire. They are falsely advertised as not protecting Important notes: 1. The higher the attenuation in dB (decibels) for a given frequency, the more the fabric attenuates high frequencies. Example: -70dB at 1 GHz attenuates much more than a fabric rated at -40dB at 1 GHz (exponential scale). 2. No fabric protects against low-frequency fields, because behind this often-used commercial misnomer lie low-frequency electric and magnetic fields. Fabrics of any kind may protect against low-frequency electric fields DEPENDING on how they are used. Otherwise, they will only discharge the electronic charges accumulated during grounding. 3. Machine washing is obviously not recommended in order to avoid twisting the fibres and causing various possible breaks, even for Swiss-made fabrics. 4. All metal mesh fabrics will be able to attenuate 99% of high-frequency fields when measured in WATTS (power measurement). However, this scale is not representative enough of the expected attenuation. Attenuation in WATTS can be correlated with attenuation in decibels. There is a logarithmic correspondence scale. The decibel (dB) measurement scale is much more precise! For example, a fabric that attenuates frequencies around 1 GHz by 20dB will attenuate the wave power by 99% in Watts. However, a fabric that attenuates 70 dB at 1 GHz will attenuate 99.99% in Watts. Therefore, the indication of 99% attenuation in Watts is not sufficiently representative of the fabric's attenuation in terms of high frequencies.
