ABSTRACT:
Individualized, stiffened, twisted cellulosic fibers and absorbent structures made from such fibers. The fibers have an average dry fiber twist count of at least about 4.5 twist nodes per millimeter, an average wet fiber twist count of at least about 0.5 twist nodes per millimeter less than the dry fiber twist count, and a water retention value of between about 28% and about 50%. Preferably the fibers have an average wet fiber twist count of at least about 3.0 twist nodes per millimeter and an isopropyl alcohol retention value of less than about 30%.
