Origin And Production Principle Of Radiation Protection Maternity Dress

The radiation protection clothing is made of metal fiber mixed fabric and has the function of reducing or shielding electromagnetic radiation and radio wave radiation.

The manufacturing process is more complicated.

The civil radiation protection clothing industry originated in China in the late 90s of last century. After more than ten years of development, a number of excellent brands such as high child radiation protection clothing have emerged, and the development of the industry has matured.

Many people think that radiation protection clothing can be used to encase the cell phone signal. Actually, this is not the case. For example, the metal coated radiant clothing can encase the cell phone signal, but there are many side effects such as the coating fabric can not be washed, the skin can not touch the skin and the airtight. It can be eliminated by most enterprises, and the test results in different environments will also be different, so the packet phone detection method is actually not scientific.

The origin of

With the popularity of electric appliances such as microwave oven, refrigerator, duplicator and computer, the coverage of electromagnetic radiation has penetrated into all aspects of human life, while fully enjoying the convenience and comfort of electrification, and also increasingly felt the danger of electromagnetic radiation.

80-120 of the 50 million newborns in China are deficient children every year. Electromagnetic radiation is proved to be one of the main inducements leading to infant defects. It is also considered by WHO International Cancer Institute (WHO/IARC) to be associated with the increasing incidence of childhood leukemia and brain cancer in recent years.

According to the internal research data of the radiation protection mothers group, electromagnetic radiation can also cause fetal gene mutations in the abdomen, resulting in stillbirth or mental retardation after birth.

It is against this background that the radiation protection clothing industry originated in China in the late twentieth Century and 90s. After more than ten years of development, a number of excellent brands emerged, and the development of the industry matured day by day.

Early

Mainly based on the blending of metal fibers, the shielding rate of this material's radiation shielding for 10-3000Mhz electromagnetic wave is above 15DB. The best is over 30DB, and the best proportion is metal fiber content above 25%.

Silver fiber radiation protection clothing appeared before and after 2002. The silver fiber fabric has a good anti radiation effect, but also has a certain antibacterial and maintenance effect on human body. Silver fiber is divided into half silver fiber and whole silver fiber according to the different content.

In addition, there are metal plated and multi ion fabrics, but they are not widely used because of airtight, improper maintenance and shielding performance, and have been eliminated by most enterprises.

Production principle of radiation protection maternity dress

Radiation protection clothing is the use of clothing metal fiber loop generated induced current, induced by the current generated by reverse electromagnetic field shielding.

A good metal conductor can reflect electromagnetic waves, that is, when the aperture of the metal mesh is smaller than that of the electromagnetic wave length (wavelength = light speed / frequency) 1/4, the electromagnetic wave can not penetrate the metal net.

All the pregnant women's radiation protection clothing on the market is made of this principle. The fabric contains conductive metal fiber or conductive silver fiber, in which metal fiber refers to stainless steel metal fiber, and silver fiber refers to infiltrating nano silver ions into nylon.

A composite fiber formed in the two kinds of fibers has good conductivity, so it can play a role in shielding electromagnetic waves.
