While most curtain kinds are fabric-based and are made from using composite materials like cotton and polyester, there are other kinds of materials too. These other kinds include cellulose (that is a mix of bamboo and wood), or even plastic panels to compress into a curtain.
The color, however, varies from fiber and fabric weave. A tight weave makes any curtain quite resistant to help the light pass through, on the other hand, a lining, backing, or can help add to make the curtained room “darker,” obscuring the interior objects and figures without ambient dimming light.
