How was the needle used to sew clothes in ancient times made?

The earliest time was bones, which were made from the bones of wild animals that came back from hunting.

In ancient times, our ancestors learned to sew simple clothes such as hides and leaves with fishbone needles and stone needles. Later, with the development of iron and metal manufacturing technology, people gradually learned to sew clothes with metal needles, and their shapes have been greatly improved, which has been used ever since.

The earliest sewing machine is a machine that sews cloth or leather with single thread, double thread or multi-thread, or sews decorative stitches on sewing materials. Used in family, industry and service enterprises.

/kloc-after the industrial revolution in the middle of the 0/8th century, the large-scale production of textile industry promoted the invention and development of sewing machines. 1790, Britain first invented the world's first single-thread chain stitch manual sewing machine, which was used to drill holes first and then thread them to sew leather shoes. 184 1 year, the French invented the chain stitch sewing machine with hook. 185 1 year, American worker Katsuya invented the lock sewing machine and established Katsuya company. Sewing machines in this period are basically manual.

1859, Shengjia Company invented the pedal sewing machine. After Thomas and Edison invented the motor, 1889, Shengjia Company invented the electric sewing machine. Since then, a new era of sewing machine industry has been created.

1940, Elna Company of Switzerland invented a portable household sewing machine, which adopted a cylindrical aluminum shell with a built-in motor. After 1950, the household multifunctional sewing machine was further developed.

Shengjia Company was founded in 185 1, and is the first sewing machine company in the United States. At that time, the output of sewing machines was second only to clocks and watches. 1870, there were 69 sewing machine companies in America. 187 1 year The annual output of sewing machines in the United States is 700,000 sets. By 189 1 year, Shengjia Company has produced100000 sewing machines. It can be said that Shengjia Company basically monopolized the production of sewing machines in the world for a long time.

After World War II, the sewing machine industry in former West Germany, Italy and Japan developed rapidly. Except those enterprises that are still producing high-grade traditional household sewing machines, most enterprises in Europe have started to produce industrial sewing machines. During this period, Japanese sewing machine enterprises began to produce cheap sewing machines with the support of the government and sold them to the United States and all over the world.

In the early 1970s, the domestic sewing machine market in industrialized countries was saturated, and Japanese enterprises had to turn to the production of industrial sewing machines in the case of rising labor costs. South Korea, especially Taiwan Province Province, seized the opportunity to make the sewing machine industry rise, produce middle and low-grade sewing machines and put them into the international market.

1975, Shengjia Company invented a computer-controlled multifunctional household sewing machine, which was gradually used in industrial sewing machines. In the early 1980s, there were more than 3,000 kinds of sewing machines in the world, and about 600 kinds were commonly used in production.
