Cuprammonium rayon, which is the variety that most closely resembles silk, was invented in 1890. The fiber is made through a process that involves dissolving the cellulose from wood pulp or cotton linters in a solution of copper oxide and ammonia, and then forcing the substance through a spinneret so that it is extruded...

Native cellulose dissolves in cuprammonium hydroxide solution, but, when it is crosslinked, it becomes a space polymer and is insoluble in this reagent. ... In all cases the cellulosic derivatives made from cellulose and compounds that could crosslink it were partially insoluble in cuprammonium hydroxide.

Cuprammonium rayon is made by converting the cellulose into a soluble compound by combining it with copper and ammonia. The solution of this material in caustic soda is passed through the spinneret and the cellulose is regenerated in the hardening baths that remove the copper and ammonia and neutralize the caustic soda.
