Compared with an aluminum alloy sunshade roller shutter, the curtain fabric type sunshade product is simpler in structure, higher in safety performance and more suitable for the technical field of building sunshade. Such as roll blinds, pleated arm type outer blinds and drop arm type outer blinds. The roll-type sun-shading curtain is mostly arranged indoors, and the performance of blocking radiation from entering the interior of a building is weak. Meanwhile, the curtain cloth is adsorbed on the window due to the pressure difference between the inside and the outside of the window, and the indoor ventilation is blocked.
