Your question is a bit difficult!
First of all, are you asking about hand-drawn silk at home or machine-made silk reeling in a factory?
If it is a family, it is very simple. Put the cocoon in hot water of about 50 degrees, soak it for a while, and then start spinning by pulling it manually, using a rotating stick. , such as a pen, you can slowly wind the silk around the pen until the cocoon finally emerges.
If it is factory reeling, it is divided into two types: standing reeling and automatic reeling. Standing reeling is a mechanical method that has been used for nearly a hundred years, and automatic reeling is a new type of mechanical reeling that has only become popular in the past 20 years. The principle is similar to that of hand reeling. The hot water first dissolves the sericin and loosens the bonding force between the loose silk and the silk, and then winds it up.
