I will list some interesting facts of Assam Silk. But, first, we will provide some basic knowledge of silk, history, types, process of making, uses, etc. of Assam Silk. Now let us dive into the post.



Silk is natural fabric made up of protein. It has many inherent characteristics. To list, some of them are.

  • Lusture,
  • Softness,
  • Elegance,
  • Versatility,
  • Wearability,
  • Yarn strength, etc

Due to the above property, it is woven into textiles. Silk fiber is obtained from the cocoons produced by silkworm larvae

Chemical Composition of Silk(Silk Protein)

Fibroin and Sericin are two important proteins which silk is made of. Fibroin(C15H23N5O6) makes up 73.5% of silk and Sericin (C15H25N5O8) 22.28% of silk. 

Since silk is a fibrous protein it is composed of a heavy chain, light Chain and glycoprotein linked by disulphide bond. Sericin acts as adhesive or gum to bond fibron for making cocoons.

Physical Properties of Silk

Silk is popular because of its unique physical properties. To list some are.

  • It is the only fibre that can be woven into fabric in its raw state.
  • A single yarn has high strength.
  • It has high elongation.
  • It is soft & Lustrous.
  • High Hairiness Value -total length of all the hairs protruding from the silk yarn (in cm)
  • Good Abrasion Resistance.
  • High Area Shrinkage.

All the physical properties are available in Assam Silk and are of high quality.


Sericulture is the process of rearing silkworms to produce raw silk. It involves 3  steps. To list, they are.

  • Growing Silkworm Foodplant.
  • Silkworm Rearing.
  • Reeling & Spinning of Raw Silk

Generally, I will discuss sericulture from two focus points- The rearing of Silkworm and Processing silk from cocoons.

Rearing of Silkworm

Assam Silkworm

Female Silk moths lay eggs. Farmers of Assam Silk Industry buy these eggs fromAssam silkworm production centres (grainages). Then, these eggs are hatched under a clean enviroment with the required temperature and humidity. From the egg, silkworm larvae or caterpillar hatches. 

These silkworm larvae feed on leaves of plants like mulberry, castor plant, oak, etc. The larvae eat these leaves and grow in size. Each variety of silkworm feed only on a particular leaves of plant.

After 30-40 days, the silkworm larvae stop eating leaves and start spinning cocoons around them. These cocoons are the main source of silk. Then, the silkworm develop into silk moth inside the cocoons.

Processing Silk from cocoons.

Sericin gums or stick together the silk fiber in cocoons. So, we need to degum the cocoon to get silk fiber. This process is called degumming. In this process, the cocoon is exposed to the sun or steamed or boiled.

Then, the silk fiber is unwinded from the cocoon. This process is called reeling. The silk fiber is then converted to silk threads to make different kinds of silk fabrics. Silk thread obtained from silkworm cocoons by reeling process is made into different types of silk fabrics.

History of Assam Silk

Assam Silk industry is the oldest and one of the largest industries in Assam. Not only this, it has become the home of the largest cluster of wavers and handlooms in India.
