Also known as the soft gauze blind, zebra blind, soft silk, dimming rolling blind, rainbow blind. It is made of small pieces of fabric of equal width and gauze interwoven into a kind of textile fabric, by one end fixed, the other end with the axis to achieve the goal of regulating the light. When gauze and gauze coincide, the light is softer, thus reduces the direct light to some extent. When the blind cloth and the blind cloth coincide, the light completely covers, thus achieves the goal that covers the light eventually. When need to open the blind completely, just rolls up the blind completely. Double roller blind combines the warmth of fabric, the simplicity of the roller blind, and the dimming function of the venetian blind. The blind is easy to operate and has various types of shading, which does not obstruct the view at all. It is an ideal choice for office and home window decoration.
