To produce rayon the old fashioned way it needs chemically intense processing of wood pulp or plant fibers. The cellulose that’s extracted is treated with caustic soda, carbon disulfide, and sulfuric acid. You’re no doubt familiar with how nasty sulfuric acid can be, but carbon disulfide is usually dangerous stuff, too and it’s exposure can lead to cramps, muscle weakness, and a loss of feeling in the extremities.
