You will never guess what happened to me today and Silkworm update
Now we have a 'chicken and the eggs' story which came first? Okay, lets start with the eggs which are layed by the moth....

Out of the thousands of eggs laid, the worms breed out. They feed mostly on Mulberry or lettuce leaves.

In a few months, they begin to spin silk cocoons around themselves and there are stunning pictures of it in "Silworm update". There they remain through the winter.......



Fine silk: "With this method a single thread is reeled off the cocoon, which was boiled with the pupae inside, because once the moth exits, the thread will be broken. Using a good quality cocoon this continuous thread can be up to 1,3 km (about half a mile) long. This is the method used for producing the fine silk associated with eastern countries." The method used is all done with expensive machines not available in smaller countried like SA.
Raw/rough silk: "In this method the cocoons are boiled after the moths exit to remove the gum-like substance called Serosin. After drying them off, the silk threads are loose and ready to be spun into threads or stretched into squares for use." This process and its weaveing is done manually or with manual looms. In the picture below, the lady is busy washing the cocoons.


Once enough have been attached to the frame, it is removed and look like this. As you can see, it is kind of lumpy and not the smooth silk one thinks it should be.

Below, a lady takes the sqares of rough silk and spins them into thread.
