Dissolving pulps require a high degree of purity used for production of cellulose derivatives such as cellulose acetate, viscose rayon, and carboxy methylcellulose, among many others. The overall fiber line yield for dissolving pulp production rarely exceeds 30 to 35%, the pulps contain a high -cellulose content (95 to 98%) and relatively low hemicelluloses (1 to 10%) and lignin (
