Style Terms explains Silk
There are two main types of silk: wild and cultivated. Cultivated silk comes from the Bombyx mori caterpillar and is fine, lustrous, and strong. Wild silk, also called raw silk, tussah, or honan, comes from wild varieties of silkworm. This type of silk is more irregular in appearance, coarser, and not as lustrous as cultivated silk.
Silk originated in China and has been produced for thousands of years, dating back to as early as 3500 BC. It is an expensive fabric, and is valued for its strength, softness, insulating properties, luster, and drape.
