Viscose is a fabric made from cellulose or wood pulp. Also called rayon in the United States, viscose is made using a process involving caustic soda and a spinneret.
First produced in 1905, viscose is a biodegradable material that accepts dyes well and resists shrinkage. The wood pulp is mashed and mixed with caustic soda. The manufacturer waits until the pulp goes through depolymerization, then adds carbon disulphide. Once the solution becomes syrupy, it is pumped into a spinneret, which is a nozzle with many small holes that form fiber filaments. Rayon is popular in the manufacture of apparel such as blouses and dresses because of its silk-like appearance. It is also used in manufacturing of vehicle tires and airline seats.
