Uv protection fabric

In recent years, due to containing halogen compounds such as freon a large amount of emissions, stranded over the earth, is broken down by ultraviolet (uv) formation of active chlorine and ozone chain chemical reactions occur, ruined the ozone in the air is hollow, the ultraviolet radiation to the ground, ultraviolet rays will cause harm to people's skin. According to scientists, predicts that by 2050 the stratosphere ozone would be reduced about 20%, then uv will bring greater harm to human health. As a result, people have developed which has the function of u.v fabric and textiles.

The principle of textile ultraviolet resistance

uv protection fabric, the mechanism has two kinds: absorption and reflection. Ultraviolet screening agent have accordingly absorption agent and reflection agent (or scattering jing) two kinds. Absorption agent and reflection agent can be used alone, also can be a mixture of both.

Uv reflection agent mainly using the reflection and scattering effect of inorganic particles, can have the effect of uv light through. Uv absorber mainly use organic material to absorb ultraviolet light, and energy transformation, in the form of heat or harmless low radiation will release or consume energy. Uv protection textiles with appropriate method processing, whatever the fiber material, can achieve good uv protection effect, and the thickness of the fabric, color and so on factors affect the performance of uv is no longer important.
