Sewing methods and precautions in the production of ton bags, and how to quickly sew ton bags.
In the process of sewing ton bags, it is necessary to sew according to the operating specifications, and the spacing of the stitches is about 1 cm; the sewing thread used must be a special thread, and the sewing thread must not have leaks, curls, floating threads, cracks, etc. The material of the upper and lower threads must be the same, and the stitches of the ton bags are rectangular, and a dead knot is made about every 10 cm.

If it is a special ton bag that requires high strength, use the reverse needle to sew back and forth 3 times, and align it with the cut edge.
