What are the production standards for stitching dust filter bags?

The longitudinal stitches of the dust filter bag must be firm, straight and not less than three. The loop stitches at the mouth of the filter bag dust collector must be firm and not less than two. The loop stitches of the anti-deflation loop of the filter bag must be firm and not less than three on each side. Less than two. The loop stitch at the bottom of the filter bag dust collector allows a single thread, but it must be sewn more than two turns. The length of the filter bag has a deviation of ±10mm, and the stitches around the filter bag must be uniform, and the filter bag must have longitudinal stitches. The size should not be less than 15 stitches/10cm, and the horizontal stitch size should not be less than 12 stitches/10cm; the sewn bag must not have holes or damage defects; the filter bag with a diameter greater than 200mm and a length greater than 5000mm should be subjected to a tensile test, and its extension The amount should meet the requirements.

2. No floating line;

3. Continuous lane drop is not allowed and no more than one lane drop within 1m.

4. The thread used for sewing the filter bag dust collector should be resistant to high temperatures, corrosion, and wear. It is recommended to use PTFE-coated or stainless steel thread;

5. The filter bag dust collector must be properly sized to fit the dust collector equipment and ensure a tight seal to prevent dust leakage;

6. The filter bag material should have good filtration efficiency and high dust holding capacity, and should be compatible with the type of dust being collected;

7. The dust filter bag should be easy to install and remove, and should not require special tools or equipment;

8. Regular maintenance and cleaning of the dust filter bag is necessary to ensure its optimal performance and service life.
