Controlling the duration of dissolving sulfite substances for high-yield fibers involves terminating solubilizing on reaching predefined correlation between quantity of raw material to be solubilized and sulfite content of sulfite solution

摘要

The method involves detecting the quantity of the material to be solubilized, determining the sulfite content of the sulfite solution, correlating the quantity of the raw material to be solubilize and the sulfite content of the sulfite solution, terminating the solubilizing when reaching a predefined correlation between the quantity of the raw material to be solubilized and the sulfite content of the sulfite solution.
