Spun silk is made by twisting together short lengths of silk retrieved from damaged cocoons or broken off during processing.
The process by which the silkworms are domesticated to obtain silk is known as sericulture.
The initial phase in the production of silk is to care for the silkworm from the egg stage until the cocoon is completed.
Mulberry trees are grown to provide worms with leaves to eat.
The silkworm caterpillar makes its cocoon by spinning a long, continuous strand and wrapping it around itself.
The process of extracting silk thread from boiling cocoons is known as reeling.
After errant strands are cleaned with a revolving brush, free ends from 4-5 cocoons flow through eyelets and are twisted into one thread and spun around a big wheel.
After that, it's distributed to spools.
The silk that has been wound onto a spool is known as reeled silk, sometimes known as raw silk.
Raw silk is boiled, washed, and stretched once more using acids or fermentation.
After that, the thread is rigorously washed several times to get the desired silk sheen.
Damaged cocoons, as well as superficial threads or waste outer layers, are teased, combed, and then spun into filaments.
