Boiling & Reeling : After sorting the cocoons, the initial step in the harvesting of silk
fibre is to kill the insect inside the cocoon.
For killing, the cocoons are boiled in water. The boiling hot water not only kills the
insects within the cocoon, but dissolves the gummy substance that holds the cocoon
filament in place. The cocoons are then dried and brushed to remove coarse outer
portion which consists of coarse filaments. After brushing, filaments from four to eight
cocoons are joined and twisted. They are then combined with a number of other
similarly twisted filaments, to make a thread that is wound on a reel.
