China's silk industry is developing rapidly, and its silk output ranks first in the world, among which cocoon silk and satin can dominate the output and price trend in the international market. Industries are mainly distributed in Jiangsu, Zhejiang, Guangdong, Guangxi, Shandong, Anhui and Sichuan, and the synergy between industries in different regions needs to be improved.
China is the largest silk producer and exporter in the world. China's raw silk production accounts for more than 70% of the world's total output, and its export volume accounts for more than 80% of the world's total trade. It is an inevitable trend of international silk consumption growth in the future to improve the scientific and technological content of silk products and develop new silk products to meet the consumption needs of emerging consumers.
The extended data filament is made of silk or synthetic fiber, artificial fiber, short silk, etc.
According to archaeological findings, about 4,700 years ago, China made silk thread, ribbon and simple silk fabrics from silk. During the Shang and Zhou Dynasties, silk fabrics such as Luo, Ling, Wan, Yarn, Crepe, Qi, Brocade and Embroidery were all made of silk. Silkworms include silkworm, tussah, castor silkworm, cassava silkworm, willow silkworm and wild silkworm. Silk strips extracted from a single cocoon are called cocoon filaments.
The emergence of reeling technology;
According to experts' research, it is found that cocoon can spin silk, and there are many possibilities. Silkworm pupa is probably one of the foods of our ancestors. When peeling, you should tear off the cocoon skin before biting the cocoon shell.
Due to accidental reasons, some people put cocoons in their mouths, and after the cocoons were soaked in saliva for a long time, sericin dissolved and the tightly wrapped cocoons separated, thus inadvertently discovering the cocoons wrapped around the cocoons. In addition, during the process of biting the cocoon shell, the silk may also be pulled out.
After repeated practice, I realized that cocoon can spin silk and peel at a suitable water temperature, so I soaked the cocoon in hot water, removed sericin, and twisted the silk thread after it floated. This is the earliest silk reeling technology.
