Mulberry silk refers to the silk made from the cocoons of the larvae of mulberry silkworms reared in captivity. The entire production process has been carefully monitored. And the environment of the silkworm larvae is also strictly controlled.
These allow for the larvae to spin silk threads that are rounder, more excellent, smoother, lighter, and more uniformly colored than any other type of silk in the world. Mulberry silk fibers are also firm, easily beating steel fibers of the same diameter in strength and durability.
