The stages of production are as follows:
- The silk moth lays thousands of eggs.
- The silk moth eggs hatch, and the larvae feed on the mulberry leaves.
- When the silkworms are about 10,000 times heavier than when they hatched, they are now ready to spin a cocoon.
- The silk is produced in two glands in the silkworm's head and then forced out in liquid form through the spinnerets.
- The silk solidifies when it comes in contact with the air.
- The silkworm spins approximately 1 mile of filament and completely encloses itself in a cocoon in about two or three days but due to quality restrictions, the amount of usable silk in each cocoon is small. As a result, 5500 silkworms are required to produce 1 kg of silk.
- The silk is obtained from the undamaged cocoons by brushing the 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 of silk filament. The silk at this stage is known as raw silk. One thread consists of up to 48 individual silk filaments.
