Mulberry Silk
Mulberry silk is cultivated silk produced by silkworms that feed on the leaves of mulberry trees. Compare with wild silk - produced by silkworms in wild feed on mixture of other tree leaves, a single thread of mulberry silk is much longer than a single thread of wild silk, so that the character of 100% mulberry silk is softer and smoother with natural silky lustre. The manufacturers of mulberry silk are mostly based in the South of Yangtze River in China, where is internationally famous for the quality of mulberry silk. The quantity of mulberry silk is very limited because of the nature production, labour input, climate change, and other nature influences. This is the reason why the price of mulberry silk is more expensive than other man-made fibres, and even more than wild silk. ',1,2,2),(4,'How is it Produced?','','
The finest silk fibers, and most of what we use today are produced by "cultivated" silkworms grown in a controlled environment. The worms are fed a diet of mulberry leaves and increase their body size 10,000 times in their short life span. Once the cocoon is spun and before the worm hatches through the silk into a moth, the cocoon is soaked in hot water then unraveled, producing filaments that can be up to a mile long in size.
The raw silk is then processed to remove the sericin - the natural "gum" that protects the fibers and causes them to stick to each other as the cocoon was spun.
Silk is a protein fiber, similar to wool or to human hair. It is only natural for silks to have some irregularities -- sometimes called "slubs". This is the nature of the 100% silk fabric.
Silk that has been processed can be woven or knit into a variety of fabrics. Silk will shrink, so if you are using it to construct clothing, be sure to preshrink it. Silk often has a wonderful feel and an almost iridescent sheen that makes us think of luxury.
The weight of silk is shown as "mm" (pronounced "mommy") and varies within the different types of silk.
