The Silk-worm eats the leaves of the mulberry tree.
When they are still very young, they eat the smaller and tender leaves of the tree.
Once they get older, they take the bigger leaves and even the twigs and stems.
Their lifespan is about 35 days, depending on the species, when it has eaten about 7000 times its original weight.
Actually, it produces two threads at the same time with a kind of glue, called sericin, from its body, in order to make the cocoon stick together.
The silk-worm produces about 2000 meters of silk for one cocoon, of which the first 500 meters are of inferior quality,(the story goes that the worm is still practising in producing) the next 1000 meters is of excellent quality,(here it becomes an "expert") and the last 500 meters is again of lesser quality, ( the worm is getting tired...)
The two parts of the lesser quality of the silk-thread are used to make the Bourette silk which looks almost like linnen, but is 100% pure silk.
Recently they have found a way to process the silk-thread without killing the silkworm.
(Have a look on the Silknews page.)
By the way, did you know that it takes 350 cocoons to make one men's silk tie?
Silk is warm in winter, cool in summer, and very light to wear.
is easy to (hand)wash in luke warm water (105F) 40C. and after light
ironing the luster and colour come back in all its glory.
