The cocoons are then kept in a warm place for several days. Great care is taken to ensure the silkworms do not hatch into moths because that would damage the cocoon and break the silk filament it has woven. To harvest the silk from the cocoons, they are placed in water to soften the filament. The softened filament is then unwound from the cocoon. One filament can be up to 1,600 yards long. It takes 4-8 of the silk filaments woven together to create one mulberry silk thread.
The silkworms may have a short life with their only purpose to be providing silk, but those short lives are pampered ones. In addition to the constant fresh supply of mulberry leaves available to them, their environment is strictly controlled to prevent them from being subjected to loud noises and strong odors such as those from fish and the human odor of sweat.
Such complicated and cautious care for the silkworms, then the great mulberry silk comes into being. It is a process the Chinese developed thousands of years ago and has perfected, making them the world’s experts in producing the finest silk, so If you would like to purchase some silk bedding or silk blankets for your baby, China will be your first choice,
