1. During the process of sewing a ton bag, it must be operated in accordance with the technical specifications, and the spacing of the stitches is about 1CM.
2. Use special ton bag sewing thread. The sewing thread must not have leaks, curls, floating threads, cracks, etc., and the upper and lower threads must be made of the same material.
3. The stitches of the ton bag are at a rectangular angle, with a dead button about every 10 cm.
4. When sewing large bags, pay attention to the alignment of the edges. Repeat the sewing back and forth three times. The end of the thread should be cleaned, and the stitches should be evenly routed.
5. In the sewing process, it is necessary to prevent the phenomenon of thread loss, and not to place high temperature objects near or around it.
6. The air needle on the upper left side of the fabric needs to be reinforced when sewing the bulk bag, and the tread distance is at least 2CM. If it is a special heavy bag with high strength, use the back needle to sew 3 times back and forth, and align with the trimming.
7. At this time, it should be noted that the thread end is not easy to be too long after the sewing is completed, and there should be no sewing errors or leaks.
