Silk damage


Silk is a natural fiber produced by the larvae to build cocoons. The silkworm secretes the sticky liquid protein and pushes it out through its mouth to make its cocoon. Unfortunately, the hatching of the silkworm destroys the thread. So the thread must be unraveled before the silkworm emerges as a moth. Heat in the form of boiling water, steam, or hot air is applied to soften the binder and unwind the cocoon. Unfortunately, the heat also kills the silkworm. To produce one pound of raw silk, about 2,500 silkworms sacrifice their lives.
