Silk is a continuous long fiber which is solidified by the silk secretion secreted by the silkworm. It is also called natural silk fiber,one of the earliest animal fibers by human use. Silk is one of the products of ancient Chinese civilization. Silkworms and silk are also recorded in Oracle. The silk thread drawn from a single cocoon is called silk fiber. When reeling silk, the silk fiber of several silkworm cocoons are extracted, and they are bonded into silk by sericin, collectively referred to as silk yarns,called raw silk. Silk which removes sericin is called refined silk. The largest amount of silk is mulberry silk, followed by tussah silk, and other silks do not form resources due to the limited amount.
