Development History Of Radiation Protection Clothing

　　 Development history

First generation Radiation-proof clothes The product is sprayed with metal paint. Spin cloth On the top, the sheet shielding layer is formed. The advantage is that the shielding effect is good and can reach more than 60DB. The disadvantage of this radiation protection clothing is that it is airtight, not bent and bulky. Like a thin iron sheet, it can only be used when the inner lining is used. This kind of radiation protective clothing is used for a long time, and it is easy to make skin allergies and other side effects.

The second generation of radiation protection clothing is coated with metal particles to form a punctate shielding layer between the longitude and latitude intersections of textile materials. The shielding clothing can reach more than 50DB and has a certain permeability. However, this kind of anti radiation clothing is easy to peel off, and can not be washed and rubbed. The shielding value will decrease after a long time, and this kind of radiation protective clothing is not suitable for direct contact with human body.

The third generation of radiation protection clothing adopts metal fiber and pure cotton fiber blending process, that is to draw metal into thin wires and form a netted structure inside the fabric. The advantages of this radiation proof clothing are good air permeability, washability, no shielding effect and no side effects on the human body. The shielding value of this radiation proof clothing is above 30DB, which is suitable for long time wear.

The fourth generation of radiation protection clothing is a multi ion fabric. The radiation protection clothing adopts absorption and transformation principle to absorb harmful electromagnetic waves and transform them into heat energy, so as to avoid the two pollution. It is the most advanced electromagnetic shielding technology in the world. At the same time, because the fabric contains a large number of metal cations, it can play the role of sterilization and deodorization, and helps the human skin microcirculation. This kind of radiation protection clothing also has the functions of anti-static, X ray and ultraviolet radiation. Moreover, this kind of radiation protection clothing is soft and comfortable, washable and wear-resistant. It is the most suitable protective material for civil use, but the price is higher at present.

The fifth generation of such protective clothing is metal fabric, which is electrolyzed. Ferry copper and silver to fabric fibre The surface of the fabric is made of fibrous metal wire. This kind of radiation protection clothing has higher radiation protection ability. But it can't be washed. It can only be dry cleaned. It can reach 80DB.

　　 Mainstream fabrics

One Metal fiber blended fabric 。 Generally, the stainless steel metal fiber with diameter of about 0.008 millimeters and cotton and polyester fiber blended into fabric, good fabric shielding value is above 30DB. Parameters: breathable, washable, stable shielding performance.

2. all silver fiber knitted fabric. The silver fiber here is not pure silver, but a new type of composite fiber made of silver ion and nylon. In addition to having good air permeability, it also has the function of bacteriostasis and maintenance to human body, and the shielding value of all silver knitted fabric is more than 70DB. This fabric is easy to oxidize, but oxidation does not affect the effect of radiation protection. clothes Use. Parameters: breathable, washable, bacteriostatic maintenance, stable shielding performance.

3. half silver fiber blended fabric. Semi silver fiber fabric refers to the fabric made of silver fiber and polyester fiber. The shielding value of this fabric is between the metal fiber and the whole silver fiber fabric. At about 50-60DB, the fabric usually has higher antioxidant capacity than all silver fiber, and it also has bacteriostatic maintenance. Parameters: breathable, washable, bacteriostatic maintenance, stable shielding performance.
