Recently, things about radiation suits have been very lively. Things started on December 18th. CCTV broadcasts the "Truth Investigation" program. An engineer Chen Feng made an experiment. The results showed that pregnant women Radiation suits can not only reflect the electromagnetic radiation passing through the collar of the maternity dress, cuffs and clothing pendulums, but will continue to refract, but it may cause the body to receive more radiation than not wearing radiation suits. The statement that “wearing radiation suits can be harmful†immediately triggered a great uproar. In response to the experimental results and the queries of consumers, the Shanghai Anti-electromagnetic Radiation Association's UN Standardization Technical Committee on Clothing Industry held a media briefing in Beijing for the first time on 22 December to issue a statement in response to the incident. The statement stated that the anti-electromagnetic radiation suit is effective for shielding electromagnetic waves. Yes, anti-electromagnetic radiation suits may not become collectors of electromagnetic waves. Consumers do not need to have any panic and fear because they have been or are wearing anti-electromagnetic radiation. In its public statement to the media, the Shanghai Anti-electromagnetic Radiation Association mentioned that Chen Feng's laboratory had conducted an experiment on anti-electromagnetic radiation garments and concluded that the anti-electromagnetic radiation clothing not only failed to protect the human body but instead It will become a collector of electromagnetic radiation and aggravate the harm of radiation on the human body. The result of such a non-standard experiment is not scientific. For the metal fiber and silver fiber fabric mentioned in the test, the reporter found that the radiation protection brand on Taobao Mall is basically the two materials. However, during the search process, another type of fabric with pearl fibers was found. At the Taobao Mall, pearl fiber fabrics are currently used only by Tianxiang and Iberian. After further investigation by the reporter, it was learned that the pearl fiber fabric was a new type of research and development. With stronger anti-radiation fabrics, Iberian brand has established a strategic partnership with Tianxiang, and they also use this kind of fabric. Is this pearl fiber fabric a better radiation protection fabric? Mr. Bai, who is in charge of Iberian market, said that the pearl fiber fabric has better radiation protection effect than the metal fiber on the market. The fabric is softer, and the radiation protection effect is stronger. It is currently a new type of fabric and is also very popular. Consumers are welcome. The reporter found that pearl fiber occupied a large number of pages in Tianxiang Taobao Mall. According to the person in charge of Tianxiang, Pearl Fiber was indeed a newly developed radiation protection fabric. This pearl fiber fabric has better protection than metal fibers. The radiation effect is more cost-effective than silver fiber, and Tianxiang is very confident in the fabric of pearl fiber.
