A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material together. It can sew cotton, linen, silk, wool, artificial fiber and other fabrics as well as leather, plastic, paper and other products. The stitches produced are neat, beautiful, flat and firm, and the sewing speed is fast and easy to use. And derived from it, hand-push embroidery, computer embroidery and other art forms. It consists of four parts: machine head, machine base, transmission and accessories. Sewing machine accessories include needles, bobbins, screwdrivers, oil cans, etc. There are many ways to classify sewing machines, and the most common ones are based on stitches and uses. The stitches of sewing machines can be classified into two categories: lock stitch and chain stitch. Lock stitch is the most common. It consists of two sutures that are intertwined like a rope, and the interweaving point is in the middle of the sewing material. From the cross-section of the stitch, the two sutures look like two locks interlocking each other, so they are called lock stitches. This kind of stitch is used in sewing materials such as cotton, woolen fabrics or leather with small shrinkage. The front and back have the same shape, like a dotted line. The stitches are densely distributed and the sewing fastness is generally better than manual sewing. Chain stitch is made up of self-connected or interconnected stitch loops. Commonly used are single-thread chain stitch, double-thread chain stitch and three-thread overlock stitch. The characteristic of this kind of stitching is that the stitching is elastic and can expand and contract with the sewing material without breaking the seam. It is suitable for garments made of threaded elastic fabrics or products and garment blanks that are easily loosened during overlocking. In addition, sewing machines can be divided into household, industrial, and service industry machines according to their uses. They can also be divided into hand-operated sewing machines, pedal sewing machines, and electric sewing machines according to their driving modes. Faced with an industry market with such great development potential, it is important to establish a brand and fight against The market starts with brand and trademark registration.
