Silk has less chemicals then those often found in other textiles like cotton, polyester and rayon.
- Silk is a natural textile woven from the protein chains making up the silk worms cocoon. These silk worms are raised in captivity and feed harvested mulberry leaves to ensure the finest silk fabric can be created. This environment is free predators, meaning less need for harsh pesticides, like those used in cotton production. To separate silk fibers, the cocoon is placed in boiling water to help the single continuous strand to separate into a thread. Compare this to rayon, where the cell walls of various materials are broken down using strong chemicals. From these broken cells, a viscous fiber is spun and the chemicals are washed away (mostly). Polyester is a spun fiber from polymer chains, in other words "oil"; the same stuff that gas is made from and you pump into your car.
