The development history of sewing machine:The sewing machine industry has experienced the transfer from Europe, the United States to Japan, South Korea, Taiwan, Singapore, since the early 1990s began to China's full transfer to the beginning of the 21st century the world has been more than 70% of the production of sewing machines in China.
However, 70%-90% of the domestic high-end machine market is occupied by Japanese and German enterprises. And in the middle and low-end sewing machine products, the world sewing machine industry has completed the transfer to China, industrial transfer gradually to the middle and high-end products.
With the continuous intensification of competition in the sewing machinery manufacturing industry, large-scale sewing machinery manufacturing enterprises mergers and acquisitions between the integration and capital operation is more and more frequent, the domestic outstanding sewing machinery manufacturing enterprises pay more and more attention to the study of the industry market, especially on the industrial development environment and the in-depth study of the buyers of products. Because of this, a large number of domestic excellent sewing machinery brands quickly rise, and gradually become the leading sewing machinery manufacturing industry.
In 1869, Li Hongzhang, a representative of the foreign affairs faction, visited Britain and brought back a gold-plated Shengjia sewing machine as a gift to the Empress Dowager Cixi when he returned home. At that time, the British media also reported the incident.
Around 1880, Shengjia set up Shanghai Fung Company in Shanghai's Nanjing Road (now 446 Nanjing Road East). In order to promote its products, the company hired Chinese female workers at a higher pay, and after training, they were allowed to bring their sewing machines to perform along the streets to introduce the operation of the sewing machines to the public, and soon the Shengjia sewing machines became well known in Shanghai as advanced garment-making machines.
For a long time, Shengjia was almost synonymous with sewing machines, and it was one of the earliest Western industrial products to enter China. In the earliest days, sewing machines were called "iron carts", "foreign machines" and "needle carts" in China. The last emperor Puyi gave the empress Wanrong a Shengjia sewing machine, which was still a rare thing in China.
In 1905, Shanghai first began to manufacture sewing machine parts and accessories, and established a number of small workshops for the production of parts and accessories.
In 1928, the first 44-13 industrial sewing machine was produced by Shanghai Xiechang Sewing Machine Factory. In the same year, Shanghai Shengmei Sewing Machine Factory also produced the first sewing machine for home use.
Sewing Machine Sewing and Principle:
When the tip of the needle passes through the fabric, it pulls a small loop from one side to the other. A device underneath the fabric catches this loop and wraps it around another thread or another loop of the same thread. In the next two sections, we'll see exactly how this system works.
The simplest coil stitch is the chain stitch. To sew a chain stitch, the sewing machine makes a loop with the same length of thread behind the thread. The fabric sits on a metal plate under the needle and is held in place with a presser foot. At the beginning of each stitch, the needle pulls a loop through the fabric. A device that makes the loop catches the loop before the needle pulls it out, and the device moves in sync with the needle. Once the needle pulls out of the fabric, the fabric feed tooth device (described later) pulls the fabric forward.
When the needle goes through the fabric again, the new loop will go right through the center of the previous loop. The device that makes the loops will grab the thread again and make loops around the next loop. In this way, each loop will hold the next loop in place.
