Abstract
The present invention relates to cellulosic substrates with reduced absorbent capacity having the capability to wick liquids, as well as to methods of manufacturing such cellulosic substrates. The cellulosic substrates provided by the present invention comprise an inside and an outside connected to the inside. The inside comprises cellulosic fibers and has a reduced absorbent capacity, and the outside comprises cellulosic fibers. The outside may have a reduced absorbent capacity and may have an absorbent capacity higher than the inside. The cellulosic substrate is capable of wicking liquid contacting the inside of the substrate to the outside of the substrate.
