The tiny silkworm as you know, however, you may not imagine that they could make great noise when cultivate the silk sheets. If you visited a silkworm producing facility and entered a room where the silkworms were being raised, it would sound like there was heavy rain falling on the roof. But it is really the sound of silkworms munching on those chopped mulberry leaves.
It takes around 30,000 silkworms to produce 12 pounds of raw silk.
The official term for silk production is “sericulture”.
Silk used in silk duvets obtained from wild silkworms, although still good quality, is not of as high a quality as silkworms who are pampered and fed an exclusive diet of mulberry leaves. Wild silkworms have to eat whatever food is available so the filament thread they weave their cocoons of is not as white as the captive raised silkworms nor is it as smooth and round.
