China's silk line has developed rapidly, silk production ranks first in the world, of which cocoon silk and satin can dominate the international market production and price trends. Industry is mainly distributed in Jiangsu, Zhejiang, the two provinces, Shandong, Anhui, Sichuan, different regional synergies between the industry to be improved.

China is the world's largest silk production and exporting countries, China's raw silk production accounted for more than 70% of the world's total output, exports accounted for more than 80% of the world's total trade volume. Improve the technological content of silk products, the development of new silk products to meet the emerging consumer demand is the inevitable trend of future growth in international silk consumption.

Silk is woven with silk or synthetic fibers, artificial fibers, staple silk.

According to archaeological findings, about 4,700 years ago, China has been using silk to make silk thread, weaving ribbons and simple silk fabrics. During the Shang and Zhou Dynasties, silk was used to weave silk fabrics such as Luo, damask, lace, yarn, crepe, chiffon, brocade and embroidery. Silkworms include the mulberry silkworm, the serpentine silkworm, the castor silkworm, the cassava silkworm, the willow silkworm, and the asparagus silkworm. The silk drawn from a single cocoon is called cocoon silk.

The emergence of reeling technology:

According to expert research, the initial discovery that cocoons can be pumped, there are a variety of possibilities. Silkworm pupa is probably one of the food of the first people, peeling food to tear off the cocoon coat, and then bite through the cocoon shell.

Because of accidental reasons, someone will put the cocoon into the mouth, the cocoon shell in the saliva after a long time of infiltration, the silk glue dissolved, dense entanglement of the cocoon silk separation, and thus inadvertently found entangled in the cocoon on the cocoon silk. In addition, in the process of tearing the cocoon shell, it is also possible to pull out the silk.

After repeated practice, realized that in the right water temperature can be extracted from the cocoon reason, so the cocoon in hot water immersion, remove the silk glue, in the silk thread floating, and then reeling silk thread. This is the earliest reeling technology.
