Wear straw hat, big sunglasses and sunscreen. On a hot summer day, everyone is thinking about sunscreen without damaging the skin from ultraviolet rays. Recently, Zhejiang Sci-Tech University professor has developed a cloth that can resist ultraviolet radiation and antibacterial skin care.
 

This "nanotechnology is natural." textile The application research in finishing process has been approved recently. Professor Liu Jinqiang, the project leader, said that this technology is to add an inorganic nano finishing agent in the dyeing and finishing process of cotton and linen, and absorb ultraviolet light through nanoparticles, thereby increasing the UV resistance of natural fibers.

At the same time, under the illumination, nanoparticles can activate the water and oxygen in the air and react with bacteria, thus killing the bacteria on the fabric. At present, the fabric has been produced for 200 thousand meters and has been put into the market.

Most people think they wear light colors in summer. clothes The human body will feel cooler, while wearing dark clothes will feel muggy.

It is cool to wear light colored clothes because light coloured clothes are more reflective than dark ones, but the reflection is mainly infrared. Ultraviolet light has a stronger penetrating power to light colored clothes, and brings greater harm to the human body. On the contrary is dark clothes, UV penetration is relatively weak.

"Ordinary fabrics have a small amount of UV protection function. When you buy clothes, you can choose a lighter color, but fibre Be careful and thicker so that it's cool and UV resistant. " Professor Liu said.
