Where are the production standards of industrial filter bag manufacturers?


In the actual operation process, due to the pinhole gaps at the stitching of the filter bag, the dust-containing air will escape from these pinhole gaps, and the emission of PM2.5 will also increase after the filter bag is cleaned. Therefore, the filter bag manufacturer can also use the technology of gluing at the filter bag sewing thread interface to reduce the influence of sewing pinholes on the filtration efficiency.


The production standard of the filter bag: the longitudinal seam of the filter bag should be firm, straight and not less than three; The annular stitches at the mouth of the filter bag should be firm and not less than two. The ring stitches of the anti-dented ring of the filter bag should be firm and not less than two on each side; Filter bag bottom of the ring seam allows a single line, but to sew more than two circles; Filter bag cutting length size deviation should be ±10mm, filter bag surrounding sewing needle code should be uniform, filter bag longitudinal needle code should not be less than 15 stitches /10cm, horizontal needle code should not be less than 12 stitches /10cm; The sewn bag shall not have loopholes, damage defects; The filter bag with a diameter greater than 200mm and a length greater than 5000mm should be stretched and its elongation should meet the requirements.
