[0002] Zebra blinds are a type of curtain, also known as soft gauze curtains, rainbow curtains, soft silk, dimming roller blinds, or double-layer roller blinds. They are made of a textile fabric woven from small pieces of fabric and gauze of equal width, fixed at one end and rolled along a shaft at the other, to adjust the light. When the gauze overlaps, the light is softened, reducing direct sunlight to a certain extent. When the curtains are staggered, the light is completely blocked, thus achieving the purpose of blocking light. When the curtains need to be fully opened, they can be rolled up completely. They are widely used in office and home window decorations.
