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.

What is claimed is: 1. A woven or knit fabric comprising: an inside surface comprising cellulosic fibers; and an outside surface comprising cellulosic fibers; wherein: the inside surface has a discontinuous hydrophobicity, the outside surface has a higher absorbent capacity than the inside surface

What is claimed is: 1. A woven or knit fabric comprising: an inside surface comprising cellulosic fibers; and an outside surface comprising cellulosic fibers; wherein: the inside surface has a discontinuous hydrophobicity, the outside surface has a higher absorbent capacity than the inside surface, and the fabric has channels of hydrophilic fibers for wicking liquid contacting the inside surface of the fabric to the outside surface of the fabric; the inside surface comprises a first yarn formed from a blend of cellulosic fibers treated with a hydrophobic treatment and cellulosic fibers not treated with a hydrophobic treatment; and the outside surface comprises a second yarn formed either from cellulosic fibers not treated with a hydrophobic treatment or from a blend of cellulosic fibers treated with a hydrophobic treatment and cellulosic fibers not treated with a hydrophobic treatment, the ratio of treated fibers to untreated fibers in the second yarn being lower than the ratio of treated fibers to untreated fibers in the first yarn. 2. The fabric of claim 1 wherein the ratio of treated fibers to untreated fibers in the first yarn is from 99:1 to 10:90. 3. A woven or knit fabric comprising: an inside surface comprising cellulosic fibers; and an outside surface comprising cellulosic fibers; wherein: the inside surface has a discontinuous hydrophobicity, the outside surface has a higher absorbent capacity than the inside surface, and the fabric has channels of hydrophilic fibers for wicking liquid contacting the inside surface of the fabric to the outside surface of the fabric; the inside surface comprises a first yarn and a second yarn, the first and second yarns being formed from cellulosic fibers, the first yarn being treated with a hydrophobic treatment, the second yarn not being treated with a hydrophobic treatment; and the outside surface comprises the first yarn and the second yarn, the first yarn being present on the outside surface of the fabric in a lower amount than on the inside surface of the fabric. 4. The fabric of claim 3 wherein the first yarn has been subjected to a discontinuous hydrophobic treatment. 5. The fabric of claim 3 wherein the ratio of the second yarn to the first yarn on the outside surface is from 99:1 to 10:90.
