Abstract

A method for sewing the glass fibre bag used for industrial dusting is disclosed, which can increase the compression strength of the weft and warp threads at the swed position, so preventing dust leakage.

Description

technical field [0001] The invention discloses a method for sewing a glass fiber dust bag. Background technique [0002] At present, in the sewing process of manufacturing glass fiber filter dust removal bags, the two sides of the glass fiber cloth are overlapped together, and several stitches are sewn by an industrial sewing machine to sew the cloth into a cylindrical shape. Such simply sewn filter bags are particularly undesirable in use. When it is used in the dust removal equipment, because it has to bear the pressure of the wind blown by the blower, there must be a phenomenon of "cracking" at the seam. That is, the pressure of the wind causes the glass fiber cloth fibers around the stitches to tear, causing large gaps in the dust bag. In this way, the dust will overflow from the gap and affect the surrounding environment. Cause damage to on-site operating conditions. Therefore, the filter dust-removing bag that sewing method is made at present is very unsatisfactory...
