The invention relates to a cloth hanging and storing device for fabrics and a temperature-reducing method thereof, which relates to the technical field of textile machinery and solves the technical problems that the production efficiency is low and the product quality is poor. The device comprises a stand, cloth rods, a transmission mechanism and a monitor system, wherein the stand is divided into a cloth-hanging region and a cloth-storing region and is provided with a circular cloth rod rail for guiding the motion of the cloth rods; the transmission mechanism comprises a transmission clutch, a transmission chain and a cloth rod propeller, the transmission clutch is in synchronous transmission with a preceding working procedure, and the monitor system controls the transmission clutch to intermittently output power; the transmission chain is connected with the transmission clutch, at least one fork is arranged at intervals for driving the hollow cloth rods to move the cloth-hanging region along the circular cloth rod rail, and the cloth rod propeller is used for driving the cloth rods in the cloth-hanging region to move to the cloth-storing region along the circular cloth rod rail and enabling the cloth rods in the cloth-storing region to move forwards by a distance of a cloth rod. The device can improve the production efficiency and the product quality.
