FIELD: textile, paper.
SUBSTANCE: method for production of sulfate cellulose from larch wood includes two stages of wood chips extraction using water at the first stage as the extractant and at the second stage - black lye, and subsequent boiling in a boiler of periodic action.
EFFECT: higher mechanical properties of cellulose and reduced value of Kappa number - when producing viscose cellulose.
