Dissolving pulp is the end-product of acid-bisulphite pulping and bleaching processes, during which almost all non-cellulosic wood components are removed to produce dissolving pulp with final a cellulose purity of up to 96%. Dissolving pulp is subsequently modified chemically to produce derivatives such as microcrystalline cellulose, viscose and acetate. Therefore, reactivity is an important aspect of dissolving pulp. This study describes the ultrastructural changes in CFA measured in dissolving pulp of Eucalyptus dried using contrasting methods. The 92 and 96% cellulose pulps were freeze-dried to avoid conformational changes, or oven-dried at 105 C degrees for 18 hours.
