METHODS OF PREPARING POLYSACCHARIDE SHEETS FOR ESTERIFICATION |
摘要 |
Processing of cellulose, and more particularly, fiber opening and downstream processing and chemistry are provided. A process includes moistening a cellulose sheet stock to a water content in a range from about 20% to about 50%, attriting the moistened cellulose sheet to a wet pulp, flash drying the wet pulp to a floccule of cellulose having a moisture content from about 4% to about 8%, and esterifying the floccule of cellulose to provide a cellulose ester product. |
