Revolutionizing Sun Protection: Nanotechnology in Fabric Development

The video discusses the risks of sun exposure, such as sunburn and skin cancer, and introduces a UV absorber developed by the Nanotechnology Center at Hong Kong Polytechnic University. This absorber, which remains effective after multiple washes, offers significant protection against harmful UVB rays. The treatment process involves dipping fabric in a solution, drying, and curing. The cost is minimal, and the treatment does not affect fabric quality. However, UV absorber clothes are not yet available in the market.

How does the UV absorber affect the properties of the fabric?

What is the current availability status of UV absorber clothes according to the text?
