The relationship between the core sewing thread and the sewing needle: Choose the thickness of the suture. When choosing the thickness of the suture, the use of thin sewing thread should be considered first. Specific considerations from the following aspects
The lock type stitch sewing machine bobbin volume is limited, the use of thinner sewing thread can accommodate longer sewing thread, saving shuttle time can be high work efficiency.
The fine sewing thread is small in size and feels good when sewing in chains
③ The space occupied by fine sewing thread is very small, which causes less fabric deformation and wrinkling.
The fine sewing thread can use small number needle, in order to avoid the fabric to produce needle hole.
⑤ Fine sewing thread can also reduce the prominent seam marks, so that it is trapped in the inner layer of the fabric surface and reduces the impact of wear. In the sewing process, to form the correct stitch, it is necessary to ensure that the stitch, stitching, sewing material three specifications match. In addition, it is also necessary to pay attention to the following two points is to consider the twist of the suture in the sewing process. The purpose of twisting the suture is to increase the strength and elasticity, but if the twist is too large, it will cause the suture roll and affect the normal formation of the thread ring. Under normal circumstances, take a 1-meter-long suture and grab the two ends of the thread to make it close together. The number of natural torsion turns of the two strands should not be greater than 6, otherwise it is easy to cause needle skipping failure.
It is necessary to use a fine needle when sewing core sewing thread if the sewing material is thin and soft, and at the same time, the recovery of the machine needle should be increased, because the friction between the sewing thread and the sewing material is small, if the recovery distance is unchanged, the relative reduction of the loop width of the surface thread will affect the normal hooking, resulting in needle skipping failure. If it is a rough hard fabric is the opposite.
