To promote the seamless design and sustainable development of air filtration materials,the current research status of air filtration materials and bags at home and abroad was summarized,with a focus on the progress of the preparation of air filtration materials and bags,including the use of PTFE,warp knitting seamless weaving equipment,cylinder needling,and the study of the performance and finite element simulation of air filtration materials.Combining the actual development of air filtration materials,the study deeply explored seamless air filtration materials from three aspects of raw material use,structural design and molding,and performance analysis.It was pointed out that developing high-performance seamless air filtration materials that meet industrial needs will be the future research direction.
