How Is Silk Material Made

Silk moths lay eggs. Eggs hatch and the caterpillars (silkworms) are fed with fresh mulberry leaves. Silkworms spin cocoons. Silk farmers heat the cocoons to kill them, leaving some to metamorphose into moths to breed the next generation of caterpillars. Soaking cocoons in boiling water can soften the sericin holding the silk fibers together in a cocoon shape. 3 to 10 strands are reeled together to form a single thread of silk, for a single thread is to fine and fragile for commercial use.
