Description

Technical Field

[0002] With the rapid development of modern science and technology, an invisible and intangible pollution source has attracted increasing attention from all walks of life. This is electromagnetic radiation, which is called the "invisible killer". For the human body, which is a good conductor, electromagnetic waves will inevitably cause a certain degree of harm. Generally speaking, radar systems, television and radio transmission systems, radio frequency and microwave medical equipment, communication transmission stations and ultra-high voltage transmission lines, as well as most household appliances, can generate electromagnetic radiation sources of various forms, frequencies and intensities.

[0003] Radiation protection clothing is mainly made of fabric with metal fibers added to form a metal fiber mesh, which is processed into wearable clothes. Clothes made of this kind of fabric have a strong shielding effect on electromagnetic radiation, which not only protects the human body from the harm of electromagnetic radiation, but also does not affect the texture of the clothes. At present, there are many kinds of radiation protection fabrics, and their radiation protection capabilities are different. When conducting radiation protection tests on fabrics, the fabrics are usually flattened to test their ability to isolate radiation. However, some fabrics need to have radiation protection properties on both sides, and the fabric clamping devices used in current testing devices are often very simple and can only be used to flatten and clamp the fabrics. When it is necessary to flip the fabrics to test the radiation protection properties, manual unloading and loading are required, which is inefficient. Utility Model Content
