1800 rayon is a shiny and lustrous thread, here is a little bit of information sourced from Wikipedia for your information:
Rayon is a manufactured regenerated cellulose fiber.
It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound. It is then dissolved and forced through a spinneret to produce filaments which are chemically solidified, resulting in synthetic fibers of nearly pure cellulose.[1]
Because rayon is manufactured from naturally occurring polymers, it is considered a semi-synthetic fibre. Specific types of rayon include viscose, modal and lyocell, each of which differs in manufacturing process and properties of the finished product.
