With the popularity of microwave ovens, refrigerators, photocopiers and computers and other electrical appliances, the coverage of electromagnetic radiation has penetrated into all aspects of human life, in the full enjoyment of the electrification of the era of convenience and comfort at the same time, but also increasingly feel the harm of electromagnetic radiation. It is in this context, anti-radiation clothing industry in the late 1990s in the 20th century, originated in China, after more than a decade of development emerged a number of excellent brands, the development of the industry is becoming more mature.
Radiation fabrics are: coated, multi-ion, stainless steel metal fiber, silver fiber. Anti-radiation clothing has experienced four generations: the first generation of copper-nickel and other coated fabrics, airtight, particles easily scattered, harmful to the human body, unwashable, has been eliminated; the second generation of stainless steel fiber fabrics, better protection, breathable, washable, the fabric is too thick, limited protection, the fiber is easy to break, is gradually being eliminated; the third generation for the silver fiber fabrics, strong protection, thin and lightweight fabrics, washable, mulberry Silk Silver Fiber Represented by mulberry silk silver fiber, natural protein and silver fiber blending, not only to maintain a strong electromagnetic radiation protection, but also to increase the health of skin-friendly performance and soft and breathable clothing wearability. The fourth generation of nano-silver ion vacuum high-energy beam plating technology, the use of nanotechnology to the traditional silver particles from 40nm to 0.1nm, reducing the gas in the active molecules and evaporation of the chemical reaction between the source material (eg, oxidation, etc.), so as to strengthen the densification, purity, deposition rate and adhesion. Conductive properties, radiation effects, antioxidant qualitative leap, but also lead to its silver content per square meter than other surface silver-plated fabrics much higher, the technology is currently the world's most advanced silver fiber processing technology, but also radiation effect is the most ideal fabrics.
Early anti-radiation clothing is mainly based on metal fiber blended prevail, this material of radiation clothing on the 10-3000Mhz electromagnetic wave shielding rate of more than 15DB, good in more than 30DB, to the metal fiber content of 30% for the best ratio. Silver fiber radiation clothing appeared in 2002 around the time of the silver fiber fabrics in addition to better radiation protection, but also on the human body has a certain bacteriostatic maintenance effect, silver fiber according to the content of the different silver fibers and half-silver fibers and silver fibers, silver fiber, silver ion ultra-precision quenching and plating of fibers, nano-silver ions, vacuum high-energy beam plating technology fiber, and so on. Early metallized fabrics, because of the airtight, not suitable for maintenance and shielding performance is not stable enough to be widely used, has been eliminated by most companies. Anti-radiation clothing is the use of clothing within the loop composed of metal fibers to generate induced current, by the induced current generated by the reverse electromagnetic field for shielding. Good conductor of metal can reflect electromagnetic waves, that is, when the aperture of the metal mesh is smaller than the wavelength of electromagnetic waves (wavelength = speed of light / frequency) 1/4, then electromagnetic waves can not pass through the metal mesh.
All the pregnant women on the market radiation clothing are made of this principle, the fabric contains conductive metal fibers or conductive silver fibers, which metal fiber refers to stainless steel metal fiber, silver fiber refers to the nano-silver ions penetrate into the nylon fiber to form a composite fiber, the two fibers have a good electrical conductivity, so it can play a role in shielding the role of electromagnetic waves. The first generation of radiation protection clothing products using the spraying process, that is, the metal paint sprayed on the textile fabric to form a sheet shielding layer, the advantage of a good shielding effect, up to 60DB or more, the disadvantage of this anti-radiation clothing is not breathable, can not be bent, bulky, as a piece of thin tin, can only be used as a lining, so that the use of this anti-radiation clothing for a long time, prone to cause skin allergies and other side effects.
The second generation of radiation protection clothing using coated coating process, so that the metal particles attached to the textile raw materials between the intersection of warp and weft, the formation of point shielding layer, this radiation protection clothing shielding value of up to 50DB or more, with a certain degree of permeability, but this radiation clothing metal particles are easy to peel off, can not be washed radiation clothing and rubbing, the use of a long time the shielding value will decline, this radiation clothing is also not suitable for Direct contact with the human body.
Third-generation radiation protection clothing using metal fibers and cotton fiber blending process, that is, the metal is drawn into a fine wire, forming a mesh structure inside the fabric, the advantages of this radiation protection clothing is breathable, washable, shielding effect will not be reduced, this radiation protection clothing shielding value of more than 30DB, but the metal fiber radiation protection clothing due to the metal wire weaving, the fibers will inevitably have a small Burrs, close to wear, it will cause discomfort, some people will even cause eczema, itching and other symptoms, in addition, spinning in the metal wire will be due to improper washing care, easy to break, affecting the use of the effect.
The fourth generation of radiation protection clothing products is the silver fiber ion fabric, this radiation protection clothing using the principle of absorption transformation, the harmful electromagnetic waves will be absorbed and converted into heat to be dispersed, to avoid secondary pollution, is the most advanced international electromagnetic shielding technology, at the same time, because of the fabric is rich in a large number of metal cations, which can play a bactericidal deodorant effect, help the human body epidermal microcirculation, this radiation protection clothing also has a Anti-static, anti-X-ray and ultraviolet radiation and other functions. And this anti-radiation clothing fabric is soft and comfortable, washable and wear-resistant, is the most suitable for civilian protection materials.
The fifth generation of radiation clothing is the application of deep-sea precipitation technology, deep-sea precipitation technology is a large number of European military and mechanical application of the technology, the metal block through a special device into the deep sea immersion, in the appropriate deep-sea seawater flow rate, ultra-low temperatures and strong static pressure, and more than elimination of compounds to make the metal block of the internal physical changes in the toughness of the metal, compressive strength and resistance to oxidation is greatly improved, so that the metal made of machinery and military machinery and oxidation, and so on, and so on. Metal made of machinery and military products have been popular around the world, solid European imports of machinery durability is very strong, this technology is applied to the field of radiation protection clothing. Tested, produced by modern technology, effective radiation shielding can reach 60DB, is the best protection technology. The sixth generation of radiation clothing is mulberry silk and silver fiber blending process, known as the "Queen of Fibers" reputation of mulberry silk and silver fiber perfect blending, mulberry silk and silver fiber radiation clothing feel softer and lighter than ordinary radiation clothing.
The seventh generation of anti-radiation clothing is processed through the nano-silver ion vacuum high-energy beam plating technology after the silver fiber and cotton fiber blending process. This radiation fabric from the conductive properties, radiation effects, or antioxidant qualitative leap, but also lead to the amount of silver per square meter than the other surface of the silver-plated fabrics much higher than the fabric is soft and comfortable, breathable, washable, green and environmental protection, the human body does not have any side effects, is the most ideal anti-radiation effect of the fabrics.
The eighth generation of radiation protection clothing is the color silver fiber blending process, is the use of electrolysis. The color silver ferry to the surface of the fabric fiber, so that the fiber like the fabric with silver wire. This radiation protection clothing has a high radiation protection ability. Distinguished from other products can not be worn, can not wash the characteristics of its special processing technology, tested, the degree of antioxidant and washing resistance is much higher than the silver fiber fabrics, effective radiation shielding can reach 70DB. Long-term work and life in the stronger radiation sources closer to the region of the population, should consider wearing electromagnetic radiation protective clothing. In order to reduce the radiation dose received, mainly including the following groups of people:
1, large, medium and small computer computing and operating personnel; 2, computer software design, programming, entry personnel; 3, occupational microcomputer users, including: finance, accounting, savings, securities salesman, commercial cashiers, microcomputer graphic designers, such as advertising design, construction, machinery, artwork, animation design, etc. As well as secretarial (typing and copying); 4, radio and television, communications, navigation, radar and other transmitter room near the field staff; 5, metallurgy, electronics, chemical, paper, wood, food and food processing industries using high-frequency and microwave equipment for smelting, welding, heating, exhausting, sputtering, drying, insecticides, disinfection and other process operators; 6, long-term operation of the use of radio frequency and microwave and other medical equipment personnel; 7, dedicated to microwave heating fast food sales attendant; 8, electronic equipment and instruments in the production of debugging staff; 9, power generation and high-voltage transmission and transformation station staff; 10, the military electronic station equipment laboratory area staff; 11, often long hours on the Internet; 12, anti-static, explosion-proof places staff; 13, heart and kidney function defects in the cell phone users; 14, in the vicinity of the radio, television, communication station People with low immunity; 15, pregnant women. 1. First of all, to determine whether the need for ultra-protective radiation clothing
Generally recommended to choose ultra-protective is working in the computer room or working environment of more than 20 computers pregnant women wear. Super anti-radiation clothing generally refers to the content of more than 50% of the silver fiber radiation clothing, to the full silver fiber knitted fabric radiation clothing the best results. General anti-radiation clothing of the ordinary protective effect of about 25% of the metal fiber, high degree of protection of radiation protection clothing metal fiber is generally more than 30%.
2. Select style
Preparing for pregnancy can first wear a bib, but once pregnant, you must wear before and after can prevent the style, on the one hand, because to ensure that electromagnetic waves do not invade the baby from behind the harm, on the other hand, should also be to protect the spine.
Radiation protection clothing styles are bibs, suspenders, aprons, vests, maternity dresses, maternity suits. How to choose radiation protection clothing, spring and summer can choose a maternity skirt or bib, fall suit or apron or suspenders can be, winter can suit or vest. In addition, it depends on the nature of the pregnant mom's work and the surrounding radiation environment. This is the strongest protection for themselves and the fetus in the womb; if the radiation around them is very weak (such as no contact with computers and little contact with other electrical appliances), you can choose anti-radiation bibs. Pregnant moms even in the case of radiation sources around them is very weak, more than three months pregnant is also recommended to choose anti-radiation horse clip, so that better protection of the health of the fetus. Fashion, health radiation protection clothing, humane care to the end, so that mothers-to-be to say goodbye to the old single-color, not enough comfort radiation protection clothing, really enjoy the fashion, comfort and health of pregnancy time.
3. Selection of fabric
Metal coated or silver fiber coated fabrics are generally hard to the touch, breathable bad. Not washable. And half silver fiber blended or full silver fiber knitted fabrics are silver ions penetration solid technology, have good breathability and can be washed directly. Then there is the metal fiber blend fabric is also a good choice.
1. The first generation of ionic silver fabrics, this kind of radiation maternity clothing has a better feel and breathability, can be gently washed. Disadvantages: The wire is easy to break, affecting the shielding effect. Because of the metal wire, most of them are stainless steel, which is not suitable for the sensitive stomach of pregnant mothers.
2. The second generation of coated fabrics, its shielding effect is good (cell phone is basically wrapped), but feel hard, breathable bad, can not be washed, the biggest drawback is plated on the surface of the metal is easy to fall off the surface into powder, if the pregnant woman inadvertently inhaled, then it will affect the health of the fetus. 3. The third generation is the fiber silver-plated radiation protection clothing, its shielding value of high efficiency, at the same time with sterilization, breathable function. The disadvantage is that it is easy to oxidize, easy to change color. 4. The fourth generation of metal fiber fabrics, soft, breathable, thin, with antibacterial, antifouling effect, long-lasting effect, and can be washed, even if the long-term wear will not oxidize, discoloration, is a safe and non-toxic green products fabrics, will not have side effects on the human body. Tested by the National Authoritative Testing Center, in the 10HZ-3000HZ ultra-broadband shielding effect of electromagnetic radiation can reach more than 80%. Metal fiber fabric is the main material on the market anti-radiation clothing.
4. Look at the size
Size is not good, fit is the best. All major radiation protection clothing brands have been investigated and experimented with, launched as many as possible to meet the various body types of radiation protection clothing.
5. Look at the price
In order to expectant mothers and babies, we can not choose the price is too low radiation maternity clothing, some radiation maternity clothing prices are very cheap, but there is a saying called wool in the sheep's body, appropriate cheaper is a normal phenomenon. But if the cheap too much nature is the difference in the quality of the product, to first compare the quality and then compare the price.
