Silk is natural, not a man-made polymer. The silk is mainly obtained from the cocoons of the Mulberry Silkworm (Bombyx mori). When the caterpillar forms a pupae, it encases itself in a cocoon of fine silk thread. Before the adult moth emerges, the cocoon is steeped in hot water to kill the developing moth inside. The cocoon is then unravelled and is combined with several other silk threads to produce a strong silk thread that can be used to produce silk fabric.
The polymer of protein is protein .
Silk is actually a polymer made by protein complexes in the repeating fashion.
Silk, a protein.
A silk worm produces silk, which is made up of proteins and amino acids that form polymers when they are joined together.
Since, according to Wikipedia's definition, "Polyacrylonitrile (PAN) is a synthetic, semicrystalline organic polymer resin, with the linear formula (C3H3N)n," and since silk is produced by silk worms, the answer must be no.
Yes, Lycra is a synthetic fabric that was made in 1958 as an alternative to making corsets with rubber. Oftentimes it is blended in with natural fabrics such as cotton or silk. It's made of polymer.
Yes, it is a polymer of Cellulose, Cellulose is a polysaccharide of Glucose and Glucose is a true organic compound.
it is nylon because nylon is a chemical

Nylon, invented by a chemist at the DuPont Chemical Company in 1935, and first used in women's stockings in 1940.
Silk would conform to this need. usually the silk from the silkworm. But some challenging items have been woven from spider silk. [In Madaskar a cloth measuring 11' by 4' was woven by 82 people over a period of 4 years, and used the silk from over a million Golden Orb web spiders. Spiders have been taken into space (a student project!) and successfully wove webs. ]
