Boiling cocoons in water is necessary to kill the pupa inside and prevent them from emerging as moths. This process ensures that the silk fibers can be harvested without damage, as emerging moths would break the silk strands. Additionally, it helps maintain the quality and integrity of the silk for commercial production. Overall, this step is crucial for maximizing silk yield and ensuring efficient processing.

Why it is necessary to kill silkmoth pupae by boiling cocoons in water?
Silkmoth pupae are typically killed by boiling cocoons to prevent them from emerging as moths and breaking the silk fibers. This process helps to maintain the quality, length, and strength of the silk threads for textile production. Additionally, it simplifies the extraction of silk fibers from the cocoon.

What is the process for making silk fabric?
first you raise silk "worms" they are really caterpillars and turn into moths. Then you kill them all by boiling the cocoons which they weave. The substance the cocoons are made of is raw silk which is later cleaned and woven into threads in a similar way cotton is.
How long does it take for boiling water to effectively kill weeds?
