In this study, polyethylene terephthalate (PET) nanofiber membrane fabricated by electrospinning was newly applied to needle‐felt filters. The PET nanofiber membrane was electrospun in an optimal condition. Nanoparticles (SiO 2 ) were used to reduce the fiber diameter. Polyphenylene sulfide needle felt (PPS NF), hot melt adhesive film, and PET nanofiber membrane were compounded into sandwich‐structured composite needle felt (PET/SiO 2 NNF) by heat treatment. The dynamic filtration performance of PET/SiO 2 NNF was compared with that of PPS NF and polytetrafluoroethylene‐coated needle felt (PTFE CNF). The results showed that PET/SiO 2 NNF had a lower rate of increase of pressure drop and a higher dust removal rate. The completion cycle of PET/SiO 2 NNF was longer than PPS NF and PTFE CNF, which extended its service life in real applications. The successful synthesis of PET/SiO 2 NNF suggested a new method to synthesize an innovative high‐performance needle‐felt filter. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
