Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons.The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture).ilk is described in a chapter on mulberry planting by Si Shengzhi of the Western Han (206 BC â 9 AD). There is a surviving calendar for silk production in an Eastern Han (25â220 AD) document. The two other known works on silk from the Han period are lost.
This silk cocoon is made of one single thread of raw silk that ranges from 1,000 to more than 3,000 feet in length. The silk is produced in the salivary glands of the silkworm and it is used for protection during the silkwormâs pupal stage. Because silk is considered one of the worldâs most beautiful fabrics, it is estimated that approximately 75 million pounds of raw silk are produced each year. It takes more than 3,000 cocoons to make one pound of silk and more than 10 billion pounds of mulberry leaves to feed the silkworms that produce the silk.
