Woven fabric is a common textile fabric formed by shuttling shuttles back and forth through a loom. Its characteristics include clear texture, soft texture and good air permeability, so it is widely used in clothing, home and other fields.   When considering whether a light box can be made with woven fabric, we need to decide according to the specific requirements of the light box. The main function of the light box is to transmit light and display text or images, so its material needs to have the characteristics of portability, good light transmission and strong weather resistance. Although woven fabric has certain light transmission, its weather resistance is relatively poor, and it is susceptible to environmental factors such as ultraviolet light and humidity, resulting in aging, yellowing and other problems.   In addition, the light box also needs to withstand a certain amount of wind pressure and gravity, while the strength and rigidity of woven fabrics are relatively low, and it is difficult to withstand greater pressure and gravity. Based on these factors, in general, woven fabrics are not the ideal choice for making light boxes. However, in some specific cases, if the requirements for the light box are not high, or if it is used in an indoor environment, you can consider using woven fabrics to make a light box. In this case, the selection of good quality fabrics is crucial, and reasonable processing and treatment are required during the production and installation process to ensure the service life and safety of the light box. In short, when making light boxes, we need to fully consider the characteristics of woven fabrics, including factors such as weather resistance, strength and rigidity. Although woven fabric has a certain light transmission, in practical applications, choosing the right fabric and scientific processing are the key to ensure the performance of the light box.
