|A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a sewing material to interlace or stitch one or more layers of sewing material. The sewing machine can sew cotton, linen, silk, wool, rayon and other fabrics and leather, plastic, paper and other products. The stitches are neat and beautiful, flat and firm, and the sewing speed is fast and easy to use. And it is derived from the art form of hand-embroidered computer embroidery.|
In the early days, it was basically a single-needle, hand-operated sewing machine, and later invented an electric-driven sewing machine, which has always been the mainstream in the market. Most of the industrial sewing machines are general sewing machines, including sewing machines, chain stitching machines, quilting machines, overlock machines and stretch sewing machines, and the sewing machine has the highest usage rate.
There are many classification methods for sewing machines, and it is more common to distinguish them by stitches and uses. The stitches of the sewing machine can be classified into two types: lock stitches and chain stitches. Lock stitches are the most common. They consist of two stitches that are intertwined like a reel, with the interlacing point in the middle of the sewing material. From the cross-section of the stitch, the two stitches are like the locks of the two locks, so they are called lock stitches. This type of stitch is used for sewing materials such as cotton, wool fabric or leather with a small shrinkage, and the front and back sides have the same shape as a broken line. The stitches are densely distributed and the sewing fastness generally exceeds that of manual sewing. In addition, the sewing machine can be divided into household, industrial, and service industries according to the use, and can be divided into a hand sewing machine, a foot sewing machine, and an electric sewing machine according to the driving form.
