In the sewing process of industrial sewing thread, it must be operated correctly according to the actual situation, and it must also form the correct stitches to achieve the effect of use. There are some problems that need to be paid attention to in the sewing process.
In the process of sewing, the polyester thread manufacturer reminds us to pay attention to the following two problems when using needles and threads. The first is to consider the twist of the suture during the sewing process. The twist of the suture is to increase the strength and elasticity of the thread, but if the twist is too large, the suture will bend and affect the normal formation of the loop, and it is easy to cause skipping stitches.
The second is the selection and adjustment of needles. When the sewing material is thin and soft, fine needles must be used, and the pick-up amount of the needles should also be increased. Because the friction between the sewing thread and the sewing material becomes smaller, if the lifting distance remains unchanged, the width of the loop of the upper thread will be reduced, which will affect the normal hooking and cause skipping failure.
