Silk varieties can be classified as mulberry silk or wild silk. Mulberry silk comes from silkworms raised in captivity, produces bright white cocoons, and results in long, thin, delicate raw silk that is smooth, flexible, and highest quality. Wild silk comes from silkworms raised in the wild, has puce or grey cocoons, and produces shorter, thicker raw silk that is pale yellow, rough but permeable, requiring bleaching before use. The document provides basic knowledge about silk varieties to give an overview and help choose cost-efficient products.
