Additional considerations in the sewing process of the sewing machine

In the sewing process, we must make sure that the needle, the suture, and the specifications of the sewing material match all three to form the correct stitch. Additionally,

The sewing process also considers the torsion of the future, the purpose of torsion of the future is to increase strength and elasticity, but if the torsion is too large will cause the suture spiral and affect the normal formation of the ring, under normal conditions the circumstances require a suture line 1 meter long to hold the two Swiss, to approach the two threads of the natural torsion twist must not be greater than 6, Or prone to eye needle failure.

In sewing, like the thin soft stitching, you should use a thin needle, at the same time, you should increase the amount of needle back, because the suture and friction of the stitching material are small, as collecting the same distance, relative to the width of the loop of the small upper thread, affects the normal hook to take, will have a failure in the jumping needle. If it’s rough cloth, it’s the opposite. This requires adjusting the relative position of the hook yarn and needle.
