ABSTRACT:
The present invention discloses a process for producing a fibrillated cellulose acetate fiber comprising contacting cellulose acetate fiber with a strong base solution at conditions sufficient to remove greater than about 5% of bulk acetyl groups from said cellulose acetate fiber. Modified cellulose acetate staple fiber comprising an outer layer of regenerated cellulose in which at least about 5% of the acetyl groups are removed on an overall fiber basis are also disclosed. Paper products incorporating said fibers are also disclosed.
