Process for making expanded fiber

摘要: A process for making mechanically expanded fiber from fibrous material having a fibrillar ultrastructure. The is made by impacting the with plurality of fine media. Impacting media causes fibers to expand form highly fibrillated form, wherein fibrils separate from, or become substantially disassociated Cellulosic particularly applicable process. preferably impacted at least until cellulose-containing phase an aqueous slurry containing 0.5%, weight, cellulosic will retain fifty percent initial volume such upon unagitated settling period sixty minutes.
