Dust filter bag filter material to go through how to process?
Compared with the general woven twill fleece after is easy to form a layer of dust, dust collection rate is high (generally up to 99.5%); followed by heat setting to ensure the dimensional stability of fiber filter, filter maintenance and reliable work, deal with the media for heat setting; there is a hot rolling process can improve the needle density, the surface smaller pores, villi melt, smooth;
First of all, the fleece will use polyester staple fiber woven twill fleece fleece by machinery, can form a layer of covering fabric pores on the surface of the short-term.
finally is the chemical treatment to improve the media, especially the performance of glassfiber filter filtration performance and strength, heat resistance, flame retardant, corrosion resistance and so on, are of great significance.The pre coating treatment and the surface covering film can well remove the remaining filter material after the dust collector is removed, thereby greatly improving the performance.
