Why are all the hotel curtains shaded?

In order to give guests a better accommodation experience, the hotel curtains are shaded. Curtains are made of cloth, hemp, yarn, aluminum, sawdust and metal materials, and have the functions of shading, heat insulation and adjusting indoor light. Curtains are divided into cotton gauze, polyester cloth, polyester-cotton blended fabric, cotton-linen blended fabric and non-woven fabric. Different materials, textures, colors and patterns are combined into different styles of curtains, which are matched with different styles of interior design curtains.
