Viscose pulp is produced from spruce wood by an acidic magnesium bisulphite production process.

Cooking the chipped wood in cooking acid with magnesium base causes removal of components (lignin, hemicellulose), which are dissolved into the liquor. Insoluble part of wood is crude unbleached pulp.

This pulp is then washed and screened in order to remove remaining cooking liquor, knots and majority of impurities.

Further, deeper removal of lignin and hemicellulose is performed by alkali extraction and oxygen beaching process. Final brightness is reached by usage of ozone and hydrogen peroxide.

After final fine screening the pulp is dried and in the form of units, containing 60 x 80 cm sheets in eight bales with 200 kg each, is dispatched.
