Abstract

Fractionated cellulosic fibers having a length weighted average fiber length of at least 2.4 mm and less than 2% by weight of fines. In another embodiment the fractionated cellulosic fibers have a length weighted average fiber length of at least 3.5 mm. In another embodiment the fractionated cellulosic fibers have a length weighted average fiber length in the range of 2.4 mm to 3.8 mm. The fibers may be used in spunlacing or airlacing.
