In the US the Federal Trade Commission has granted Courtaulds Fibers Inc. a temporary designation for use in marketing a new generic manufactured fibre with the proposed name Lyocell. Composed of precipitated cellulose, the fibre is produced by an organic solvent extrusion process. The solvent spun rayon is currently in commercial use in Europe, and Courtaulds is planning to begin production at its Alabama plant in mid 1992 with an initial capacity of 40m lb per year.

The use of Lyocell as a generic label in the USA was delayed by a few years due to the FTC deliberations over whether lyocell was a rayon or a new class of fibre.  In the meantime "CF0001" was the permitted generic and this was used at the launch of Mobile production.
