As a light-control blind, Shangri-la blind has a pair of parallel sheets with multiple blades. When the blind is closed, the blades are substantially parallel to the pair of sheets, and when opened, the blades are extended substantially perpendicular to the pair of sheets. Among them, the sheet and the side yarn are integrated into a whole through textile or other processes. When fully open, the two layers of tulle are perpendicular and parallel to each other. At this time, when the height of one side of the yarn passes through, the light will reduce the incidence. When the two layers of tulle are close to each other, the light is completely blocked, and the height of the blind is adjusted. Will roll up along the upper axis, so as to have a good light control effect. The Shangri-la blind has a unique texture and beautiful appearance. The horizontal fabric is connected in two layers of soft fabrics to keep the interior light soft. Turning the blades can adjust the intensity of the light. The blind can be completely hidden in the curtain box when pulled up. The unique texture of the fabric can keep the color consistent for a long time. Strong light-shielding, the simple structure of the track and bracket is more convenient during installation and easy to clean. The fabric can be cleaned with ultrasound to make the fabric as beautiful as new. Shangri-la curtains can be divided into bead chain pull type blind and electric take-up type blind according to the operation mode.
