In 1891, Three Englishmen, Charles Cross, Edward Bevan and Clayton
Beadle, made an interesting discovery when they treated
cellulose with sodium hydroxide and carbon disulphide, it transformed
into a water-soluble complex.
Also:
In 1846 Christian Friedrich Schönbein added raw cotton to an acid bath (a mixture of sulphuric and nitric acid). He then washed and dried it, the sample looked the same as before but felt much rougher. Schönbein treated his newly found material with different solvents and discovered that it easily dissolved in a mixture of ether and alcohol, producing a sticky and thick solution. Schönbein had thus succeeded in transforming the
normally insoluble cellulose into a soluble form. Note - May explode as nitrites are formed.
