You can consider fabric curtains with deep colors. Fabric curtains are affordable and beautiful in color. As long as the knitted lines are thin, it can basically meet the shading needs. When choosing, cover the curtain cloth on your head and look at the direction of the light, so that the texture of the cloth will not penetrate the bright spot.
For daily life, don't blindly pursue too high shading rate, because many shading fabrics with good shading effect adopt coating technology, and the coating and cloth are bonded with glue. Glue may contain harmful chemical components such as benzene, formaldehyde or methanol, which will be released for a long time after the curtain is hung, which is not conducive to health. If you really need to use a shade cloth, don't be greedy and cheap, try to choose a woven shade cloth. This shade cloth is divided into three layers when woven. The upper and lower layers can be woven in various colors like ordinary curtains, and a layer of black fabric is sandwiched between them, giving consideration to shading effect and aesthetic and environmental protection.
