VİSCOSE RAYON FILAMENT

Cellulose, originally from cotton linters but now chiefly from wood pulp, washed, bleached, and pressed into sheets, is dissolved by sodium hydroxide, then forced under pressure through minute holes in a metal cap (spinneret), emerging as filaments that unite to form one continuous strand solidified by passage through a suitable liquid or warm air. These filaments are very bright, in order to attain dullness titanium dioxide is applied before injection.
