The silkworms and mulberry leaves are placed on trays.
-
Twig frames for the silkworms are prepared.
-
The cocoons are weighed.
-
The cocoons are boiled and the silk is wound on spools.
-
The silk is woven using a loom.

Peace silk
The most popular substitute for traditional silk is peace silk, also known as ahimsa silk. The primary factor that makes this form of silk more ethical is that moths are permitted to emerge from their cocoons and fly away prior to boiling. It denotes that no pupa is ever cooked alive during manufacture. However, there is a big disadvantage to be aware of. Domesticated silkworms used to make silk have undergone thousands of years of selective breeding, yet they are not "manufactured" to emerge from their cocoons. They are unable to defend themselves against predators since they cannot fly or see clearly. They typically die very rapidly after emerging from their cocoons as a result.[10]
Wild silk
The cocoons of Tussar silkworms, which are found in open woodlands, are used to produce wild silk, also known as Tussar silk. Compared to conventional silk, their cocoons are typically picked after the moths have emerged, making it a more ethical option. Because wild silkworms consume a variety of plants, their fabric is less uniform but more robust. The fabric is made with fewer chemicals as well. The pupae are still inside the cocoons when they are harvested by certain enterprises that employ "wild silk", though.[11]
Stages of production
The stages of production are as follows:
- The female silkmoth lays 300 to 500 eggs.
- The silkmoth eggs hatch to form larvae or caterpillars, known as silkworms.
- The larvae feed on mulberry leaves.
- Having grown and moulted several times, the silkworm extrudes a silk fibre and forms a net to hold itself.
- It swings itself from side to side in a figure '8', distributing the saliva that will form silk.
- The silk solidifies when it contacts the air.
- The silkworm spins approximately one mile of filament and completely encloses itself in a cocoon in about two or three days. The amount of usable quality silk in each cocoon is small. As a result, about 2,500 silkworms are required to produce a pound of raw silk.[12]
- The intact cocoons are boiled, killing the silkworm pupa.
- The silk is obtained by brushing the undamaged cocoon to find the outside end of the filament.
- The silk filaments are then wound on a reel. One cocoon contains approximately 1,000 yards (910 m) of silk filament. The silk at this stage is known as raw silk. One thread comprises up to 48 individual silk filaments.
Pupae as food
The conventional method of silk production results in ~8 kg of wet silkworm pupae and ~2 kg of dry pupae per kilogram of raw silk.[16] This byproduct has historically been consumed by people in silk-producing areas.[16][17]
