Silk is one of the world’s most enduring symbols of beauty, fulfilling a human love of luxury that no other fabric could satisfy so completely and in so many forms. Traditionally silk was reserved for royalty, but is now available to all lovers of fine quality fabrics.
This highly desirable fabric, is composed of yarn that are triangular in cross-section, which explains the way light dances across the woven fabric giving it that characteristic lustre. Silk has the strength of a strand of steel the same size, and is far stronger than cotton, wool or linen.
Silk is a natural fiber generated from silk worm, with mulberry tree leaves as their food, so silk is ecologically natural organic fiber, renowned as "queen of fibers", "source of beauty", "healthy fiber" and "health protection fiber". It's unique function to enhance human body's health is incomparable and none-substitutable by any other fibers. Silk cloth can prevent ultraviolet ray from penetrating, pushing away harmful air or germ from human skin, acting like a natural guardian to us.
As the queen of all fabrics, silk is the most elegant and noble fabric ever known to mankind and below are some interesting facts:
1.Silk culture has been practiced for at least 5000 years in China
2. The Silkworm (Bombyx mori, Latin for "silkworm of the mulberry tree") is, technically, not a worm. It is the larva or caterpillar of a moth in the family Bombycidae
3. A silkworm's diet consists solely of mulberry leaves
4. The silkworm (Bombyx mori) is entirely dependent on humans for its reproduction and no longer occurs in the wild. It is native to northern China. Its nearest wild relative is Bombyx mandarina with which it is able to hybridize
5. The silkworm female deposits around 400 eggs at a time. In an area the size of your monitor screen, about 100 moths would deposit more than 40,000 eggs, each about the size of a pinhead
6. The female dies almost immediately after depositing the eggs; the male lives only a short time after. The adult does not eat during the short period of its mature existence
7. The shimmering appearance for which silk is prized comes from the fiber's triangular prism-like structure which allows silk cloth to refract incoming light at different angles
8. Silk fibers are very fine, about 10 nanometers (1/2500th of an inch) in diameter
9. Strong as steel in tensile strength, silk is the strongest natural fiber known to man
10. Silk is much lower in density compared to cotton, wool or nylon.It is highly moisture absorbent, able to absorb as much as a third of its own weight in moisture without feeling damp.
11. Current world silk production is estimated to be around 125,000 metric tons. China produces about 80% of the world's silk; and India over 10%
12. Japan, Korea, Thailand, Vietnam, and Uzbekistan also have a significant production of raw silk and silk yarn. Brazil is the only non-Asian country that is a significant producer of raw silk or silk yarn .
13. United States is the largest silk importer in the world
