In order to meet the increasingly stringent emission standards,the bag-making process and sealing methods are particularly important. The phosphor permeation and filtration properties of filter bags prepared by three-needle sewing process (without sealing treatment),pinhole glue sealing process after three-needle sewing and hot melt sealing process were studied. The results showed that the filter bags prepared by pinhole glue sealing process after three-needle sewing and hot melt sealing process could block dust permeation and the filtration efficiency was relatively higher,no matter they were phosphor permeation test or dynamic dust removal filtration test. Among them,the filter bag prepared by pinhole glue sealing process after three-needle sewing had the best filtration effect with small filtration area loss and suitable air permeability.
