| titleOfInvention | A method of manufacturing dissolving pulp using coniferous wood material |
| abstract | The present invention relates to a method for manufacturing dissolving pulp using wood material, the method comprising the steps of;subjecting the wood material to a hydrothermal treatment using steam and/or water, a) digesting the wood material obtained from step a) to a pulp in a kraft cooking process;b) subjecting the pulp to a cold caustic extraction CCE; andc) dewatering, washing and pressing the pulp to get a pulp product having a carbohydrate content.The wood material is a coniferous wood material, and whereby the mild hydrothermal treatment is performed to reach a P-factor of from 100-300, and whereby the cold caustic extraction is executed to reach a combined concentration of anhydromannose and anhydroxylose of 4.5 weight %, or less, of the carbohydrate content of the pulp product. The method as disclosed herein fills the currently existing gap between a regular kraft cooking process, using additives such as borate in a preceding step, and a process involving a harsh hydrothermal treatment. |
