Silk
Silk is a long continuous yarn produced by worms that feed on leaves of mulberry trees.
Worms weave cocoons with their saliva when they turn in Chrysalis Larva in their life cycle.
The fibre they produce can be derived from cocoons and ground in a long thin wire, which is then woven in silk clothing.
Cultivation of Silkworm and Silk-weaving techniques development began in China around 2700 A.v. JC.
Silk was a product of great value at this time and a trade route from China to the Mediterranean was opened and called the Silk Road.
In Thailand, traces of the excavations of Ban Chiang suggest that the independent production of silk existed already at that time.
