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.
Why are silk cocoons boiled?
Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.
Can boiling water effectively kill cockroaches?
Yes, boiling water can effectively kill cockroaches by scalding them.
Does boiling water kill spores?
Boiling water does kill spores. This is because spores are like tiny plants in storage so the boiling water harms them.
Can boiling water permanently kill grass?
Boiling water can kill grass temporarily, but it may not permanently kill it as the grass roots can regenerate.
Does boiling water kill grass when poured on it?
Yes, pouring boiling water on grass can kill it by damaging the plant cells and roots.
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?
Boiling water can effectively kill weeds by damaging their cells and roots. It usually takes about 30 seconds to 1 minute of exposure to boiling water to kill weeds effectively.
How long does it take for boiling water to effectively kill bacteria?
Boiling water for at least 1 minute can effectively kill most bacteria.
Can you effectively kill weeds by pouring boiling water on them?
Yes, pouring boiling water on weeds can effectively kill them by damaging their cells and roots.
