It is not known when the domestic silkmoth diverged from its wild relatives, only that the domestic population originated from inland Chinese rather than Japanese or Korean stock (Maekawa et al. Making a single kimono requires the silk from 2100 silkworm moths. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. It is difficult to remove tough stains such as grease because of the fine nature of silk. Silk culture has been practiced for at least 5,000 years in China (Goldsmith et al. In addition to the eyes, almost all arachnids have two other types of sensory organs. How to Remove Fresh Alcohol Stain Moisten a soft cloth or sponge with warm water. Females have about twice to three times the bulk of males (for they are carrying many eggs), but are similarly colored. [citation needed]. Other silk producers include two giant silkworms in the Saturnidae family, Samia cynthia and Antheraea pernyi.

The eggs are covered with gelatinous secretion by which they stick to the leaves. However, for stubborn wrinkles, you have to iron the silk sheets. The nutritional value of carbohydrates According to the nutrition test, The diameter is generally a few micrometers to tens of micrometers, and the length is a hundred times or more than a thousand times larger than the diameter of the elongated substance is called fiber. Silk-fiber is a protein produced from the silk-glands of silkworms. Many other Lepidoptera produce cocoons, but only a fewthe Bombycidae, in particular the genus Bombyx, and the Saturniidae, in particular the genus Antheraeahave been exploited for fabric production. Heres how to get wrinkles out of silk. Naked and cold, she spit out the net and used it as a blanket to sleep.
