Raw silk is harvested from cocoons of silk worms. The cocoons are lowered into hot water, which terminates the worm's use of the cocoon. Then the cocoon is carefully unwound to produce strands of raw silk. Additional processing may take place, depending on the type of raw silk being produced. The worm is disposed of.
It takes about 2,000 to 3,000 cocoons to produce 1 kg of raw silk. Each cocoon is made up of a single continuous thread of silk spun by the silkworm larvae.

The raw materials for silk come from the tiny creature known as the silk worm, which is the caterpillar of the silk moth Bombyx mori.
The raw material for processing silk is silk worm cocoons, which when unraveled can measure more than 3,000 feet in length.

From silkworms.
If a single cocoon were taken apart, you would end up with 300 to 900 meters of raw silk thread about 10 micrometers in diameter. Thus, any of the common length units would apply to raw silk thread. If these silk threads are woven into fabric. the fabric may be specified in yards or meters (of a standard width.) Silk is often dyed. Dyers would typically use weight measure for silk. To make a pound of silk, typically about 3000 cocoons are boiled in water. Boy, it sounds like silk takes a lot of work to produce! It's no wonder that silk sheets cost so much!
In 1995, over 30 countries were reported as producing silk, the two largest silk producers were China producing 54% and India producing 14%.
