And derived art forms such as hand-push embroidery and computer embroidery. There are many classification methods of sewing machines. The more common ones are distinguished by stitches and uses. Type stitch is the most common. It consists of two sutures, which are intertwined like twisted ropes. The interweaving point is in the middle of the sewing material. From the cross-section of the stitches, the two sutures are like two locks interlocking each other. Therefore, it is called a lock stitch, which is used in sewing materials such as cotton, wool fabric or leather with a small shrinkage rate. The front and back sides have the same shape, just like a dotted line. Sewing, the sewing machine presser foot is an essential part of the feeding mechanism of the sewing machine. The sewing machine presser foot plays a very important role in the production process, such as special sewing machine presser feet for top thread and hidden zippers, and pleated sewing machines Presser foot, etc., the presser foot is mostly controlled manually during use, which is more troublesome
