Abstract
Literature Survey
Introduction
The cold soda pulping process was developed by the Forest Products Laboratory, Madison, Wisconsin, around 1950. It is a high yield process in which wood chips are softened by reacting with sodium hydroxide and then defiberized by mechanical refining. The yield is usually between 80%-95%.
Cold soda pulps with the following characteristics were used for this literature survey: The yields were between 80%-95%. The pulping temperatures were less than 40°C. The pulping operations were conducted under atmospheric pressure.
