Radiation protection suits were born in the 1990s and were first used in the aerospace industry. In response to the modern war, the US military has equipped the Marine Corps with radiation protection suits to prevent electromagnetic detection. In addition, radar operators and electronic warfare pilots are also equipped with radiation protection suits. Japan was previously a major exporter of silver fiber, and radiation-proof clothing fabrics experienced four key technological changes during the production process.
Radiation protection fabric process upgrade:
1. Spraying technology radiation protection suit. The spraying process is the first generation of anti-radiation maternity dressing, which is made by directly spraying metal paint on the surface of the garment. The radiation protection suit made by this process mainly utilizes the electrical conductivity of the metal and has a good shielding effect. However, due to the rigid nature of the metal, the metallic paint directly sprayed on the surface of the garment will form a rigid coating. The pregnant mothers will not only have a heavy feeling after wearing, but also make the fabric texture rough and poorly breathable, so this The production process has been eliminated by the market.
2. 踱 film coating process. The enamel film has been attached directly to the intersection of the warp and weft of the textile fiber. The anti-radiation maternity dress made by this process also utilizes the conductive properties of the metal, the anti-radiation effect and the radiation protection made by the coating process. There is not much difference in maternity clothes. However, the breathability and wearing comfort are better than the anti-radiation maternity dressing of the coating process, and are used by most companies in the production of anti-radiation maternity clothes.
The radiation protection suits made by these two processes are not suitable for pregnant women, mainly for industrial production protection. There are two reasons for this:
1. The wearing comfort is poor, and the radiation-proof fabrics produced by the spraying and coating process are generally hard. 2. Poor stability The metal coating of the spray is easy to fall off, and the dust that is shed during the wearing process is also greatly harmed by the pregnant woman. Falling off after cleaning also affects the service life of the radiation protection suit. The radiation protection suits produced by these two processes cannot be cleaned, which is not hygienic, and it is easy to cause bacteria to exceed the standard, and is not suitable as a pregnancy and baby product.

3. Metal fiber blending process. The metal fiber blending process is made by drawing metal into filaments and inlaid into the inner blended cotton fabric of the garment. The principle of radiation prevention is to utilize the annular current formed by the inner wire of the garment to shield the electromagnetic radiation. The radiation protection suit made by this process can not only be washed, but also has stable radiation resistance, and the ventilation performance and comfort are stronger than those of the other two processes. It is the most advanced production process for metal fiber radiation protection clothing on the market. It is used by most well-known enterprises in the field of radiation protection clothing to make radiation protection suits. The first brand of radiation protection clothing is the largest silver fiber producer and seller in China. In the production of metal fiber radiation protection clothing, not only the metal fiber blending process is used, but also the high quality pearl fiber is added in the production of radiation protection clothing. After wearing, the mothers are not only refreshing, breathable, soft, and skin-friendly. They are also suitable for pregnant mothers to wear.

4. Nano silver ion vacuum high energy beam plating technology. Silver fiber has the characteristics of antibacterial, deodorizing, flexible and strong radiation resistance, and is an ideal material for making radiation protection clothing. Because of the high requirements of raw materials and processing technology, an early silver fiber radiation protection suit was used. In recent years, the technology has matured and the cost has decreased. The biggest disadvantage of silver fiber fabrics is that they are easily oxidized. The oxidized silver fiber fabrics exhibit black wadding, which affects the aesthetics of the clothes (the radiation efficiency after oxidation is not affected, and the silver oxides still have strong electrical conductivity). To this end, as the first brand of domestic radiation protection clothing, the fragrant radiation protection, continuous improvement technology, in the production of anti-radiation maternity clothing, using ultra-precision quenching technology, changing the traditional silver ion sputtering process, reducing the traditional silver ions For the traditional 1/10, the traditional silver ion is refined to 0.1 nm, and the laser plating process is used to increase the arrangement density of silver ions and the degree of fiber penetration, and the conductivity, protective effect and oxidation resistance are greatly enhanced.
Metal fiber radiation suits and silver fiber radiation suits can meet the daily protection needs, of which metal fiber cost-effective, metal fibers are often made into aprons, jackets, with bottoming, is the first choice for spring and autumn. The silver fiber radiation suit is soft and breathable, and is often made into a halter top for a cool summer wear. The majority of pregnant mothers can wear according to their own needs and seasons.
