1 Hand-spun silkworm cocoons are poured into boiling water for soaking. After a while, there will be a lot of silk heads in it with a brush. Then put the silk heads on the wooden wheel, and then roll the wooden wheel, so that the silk will come out. But the thickness of the silk is uneven and there are many broken ends.

2. At present, the processing plant has a special wire drawing machine, which has a good drawing level, is not easy to break and has high efficiency. It's much faster and more convenient than the traditional method that some people flatten the cocoon and reel off silk.

The automatic reeling machine has different sensing types, which can be divided into two types: fixed particle sensing reeling and fixed fiber sensing reeling. Fixed-grain sensing is to keep a certain number of cocoons in each raw silk during reeling, and to add and connect threads if there is no grain; Fixed fiber sensing reeling uses a size sensor, and when raw silk is thin to a certain limit (called fine size), threads are added and connected. Thread represents the cocoon silk head of each cocoon.

According to the different winding forms of raw silk, it can be divided into two types: small coil reeling and bobbin reeling.

Reeling in small rolls is to wind raw silk on small rolls, then return it to large rolls with a circumference of 1.5 meters, and then make it into a hank.

The specific method of extracting from silkworm cocoons is to pluck messy silk-make solution-soak-pick silk head-extract silk.

Extended data:

Cocoon refers to the cocoon of silkworm. The capsule-shaped protective layer of silkworm pupa contains pupa. Cocoon layer can be used for reeling, and cocoon coat and waste silk after reeling can be used as raw materials for silk cotton and silk spinning.
