ABSTRACT:
Readily hydratable cellulose products prepared by acid treatment of highly fibrillated filbrillatable cellulose precursor such as wood pulps. Highly flocculent slurries are formed when the products are mixed in water. The slurries exhibit slow settling rates and the material gradually settles, after prolonged standing, into a highly flocculent, uncompacted mass below a layer of crystal clear aqueous medium.
