Silk
Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is composed mainly of fibroin and produced by certain insect larvae to form cocoons. The best-known type of silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.

Famous quotes containing the word silk:
“O bid me mount and sail up there
Amid the cloudy wrack,
For Peg and Meg and Paris’ love
That had so straight a back,
Are gone away, and some that stay
Have changed their silk for sack.”
—William Butler Yeats (1865–1939)
“Come, let me sing into your ear;
Those dancing days are gone,
All that silk and satin gear;
Crouch upon a stone,
Wrapping that foul body up
In as foul a rag....”

“All-destroying sword-blade still
Carried by the wandering fool.
Gold-sewn silk on the sword-blade,
Beauty and fool together laid.”
