Video: How Silk is Extract from Silkworm
This video explains the process of how silk is extracted from the silkworm. Silk is a natural protein fiber that is lightweight, strong, and has a high level of elasticity. It is produced by certain insects, most commonly the silkworm, through a process known as "sericulture". The video starts by showing a silkworm cocoon, which is the stage at which the silk is contained within the insect's body. Then, it demonstrates how the cocoon is opened and the silk is extracted using hot water or an acid solution. The resulting silk is then cleaned, dried, and spun into yarn or thread. The video concludes by showing a finished silk product, such as a scarf or suit, which are made from the extracted silk fibers.
The process of extracting silk from silkworm is a traditional craft that dates back to ancient times. Silk, which is also known as "the queen of fabrics", has been highly valued for its unique texture, appearance, and functionality for thousands of years. In this video, we will explore the fascinating journey of how silk is made from silkworm, from the initial stages of cocoon formation to the final process of silk reeling.
Firstly, to make silk, we need silkworm eggs. These eggs are hatched into larvae, which are then fed on mulberry leaves. As the larvae grow, they secrete a liquid called "silk fluid" from their salivary glands. This fluid is then coagulated to form a thread-like structure, which is then spun into silk fibers.
The next step is for the larvae to create a cocoon. They do this by spinning their silk fibers around themselves to form a small, round shell. The cocoon acts as a protective casing for the larvae as they undergo their final transformation into pupae.
Once the larvae have completed their cocoon formation, they enter the pupal stage. This is when the silkworm transforms from a caterpillar into a moth. The pupae are usually enclosed in their cocoons for several weeks before emerging as moths.
Finally, to extract the silk from the cocoons, we need to boil the cocoons in a pot of water. This process is called "reeling". When the cocoons are boiled, the silk fibers inside are loosened and can be easily pulled out. The silk fibers are then cleaned and dried to form a continuous, strong thread that can be used to make textiles or other products.
In conclusion, the process of extracting silk from silkworm is a labor-intensive and time-consuming task that requires great patience and skill. However, the end result is a beautiful and valuable fabric that has been prized for centuries. Silk not only provides us with a beautiful and comfortable fabric but also has numerous applications in various industries such as automotive, aerospace and even medical fields due to its unique properties such as high tensile strength, flame retardant and hypoallergenic qualities among others..
