Quick Summary

Sericulture is the process of raising silkworms to produce raw silk. The domesticated silkworm (Bombyx mori) spins a cocoon from a continuous filament secreted from glands in its head. This filament, composed of fibroin and cemented by sericin, hardens upon exposure to air. After the larva is killed in the chrysalis stage, the cocoon filament is unwound, or reeled, to form raw silk. Several strands are twisted together to create stronger yarn.1

Silk thread is known for its elasticity and strength, making it suitable for sewing fine fabrics like silks and wools. A specialized, stronger, and lustrous silk thread called buttonhole twist is used for hand-worked buttonholes and decorative effects. Historically, silk production originated in China and spread through trade routes like the Silk Road.23
