Silk Production Life cycleSilk can be produced by wild caterpillars or mulberry silkworm. Compared to the wild silks, the scale of cultivated silks is far bigger and the quality of silks is more controllable. The most popular type of silk is produced from cocoons made by the larvae of the mulberry silkworm. The whole life cycle of silkworm has four stages: egg, larva, cocoon (pupa), and moth. The commercial silk production happens at the third stage: cocoon or pupa before the pupae make damage by the emerging moth. It takes around 30 days to become mature silkworm from larva with enough food - mulberry leaves. It spins and makes cocoons, then turns into pupa. The pupa becomes a moth in about 10 days and a moth comes out the cocoon shell. The female moth dies almost immediately after the egg depositing. The male lives only a short time after. The silkworm contributes one of the most luxurious fabrics within a short time life cycle.UsesSilk has a widely application in a clothing industry such as formal dresses, fashion clothes, bathrobes, pajamas, scarves, cufflinks, and underwear.
