Question

Why do we need to boil the cocoons for extraction of silk

Answer 1

Cocoons are set in boiling water to disintegrate the glue that passes one strand of silk to the layers beneath. This permits a single silk strand to be unrolled from the case (for the most part around 20 strands are loosened up together and this fiber package is then spun into a string that is utilized and hence woven).

Grouping 20 or so strands together considers a few to break and be replaced amid the loosening up process without negative diminishing of the fiber package. Each cocoon has around 3000 meters of the single fiber.
