BIRTH OF RAYON(1855)
Probably the most famous chemist when it comes to the history of rayon fibers is, Georges Audemars. His groundbreaking patent describes the entire process in which to obtain a regenerated cellulose fiber. That fiber will later be known as rayon. I want to give you the basic steps of his process as they are the building blocks to everything to come.
Boil the bark from mulberry trees in water in order to separate the inner bark. The inner bark will become the soon to be fiber.
Create a pulp from the inner bark using carbonate soda, soap and nitric acid.
Soak that pulp in an ammonia-alcohol solution and bleach it with chloride of lime.
A end fiber is created. This fiber can be “hackled, combed or carded and then spun like cotton”.
He mentions the ability to use this end fiber for photographic purposes by converting it to an “explosive compound” and doing some more chemistry. He also recognizes the fiber as a substitute for silk.
