The advantages of the bag house are expounded in this paper. The some technical parameters of the filter bag are introduced. The weaving plan of three-dimensional angle-interlock tubular fabric is designed. The key points of weave production are explained. Use of angle-interlock tubular structure can weave seamless and thick the filter bag, and improve the filter efficiency of woven fabric. The development of seamless filter bag save sewing process, and improve the production efficiency, and save cost. The seamless filter bag with three-dimensional angle-interlock structure can be widely used to a lot of areas of flue gas filter. It will play a positive role to protect the environment.
