The invention discloses a storage device for microfiber fabrics. The device comprises a box body, wherein the right side of the box body is fixedly connected with a shell, the top of the right side ofthe shell is fixedly connected with a motor, and the output end of the motor is fixedly connected with a first rotating shaft. According to the device, through the cooperative use of the box body, amesh box, a particle drying agent, a second rotating shaft, the first rotating shaft, a ultraviolet sterilization lamp, a winding roller, a humidity sensor, a driving wheel, a motor, the shell, a belt, a driven wheel, a small-sized dehumidifier, an electric telescopic rod, a transverse plate, a pressing plate, a second box door, a first box door and a controller, the problems that when existing storage device for the microfiber fabrics winds and stores the microfiber fabrics, flattening and tightening on the microfiber fabrics is usually inconvenient, so that wrinkles are prone to occur in thewinding process, the moisture-proof effect is usually poor, and the air humidity in the box body can not be automatically controlled, so that the microfiber fabrics are prone to be damaged to some extent in the storage process are solved.
