Abstract
Absorbent articles, such as diapers, sanitary pads, incontinence products, and similar articles can utilize cellulosic structures as a sustainable replacement for conventional polymers, delivering performance comparable to plastic-based materials. These articles can incorporate a cellulosic top sheet and/or back sheet with a hydrophobic treatment. They may also incorporate cellulosic materials for acquisition and distribution layer, core wrap, and/or core.
Claims20
An absorbent article comprising:
- a layer that comprises a fabric of cellulosic fibers treated with at least one hydrophobic treatment selected from the group of:
- blending with synthetic fibers,
- leaving at least a portion of said cellulosic fibers unbleached so as to leave inherent lignin present, and
- applying a hydrophobic agent to at least one surface of said cellulosic fibers, such agent being applied to at least one of a surface of said cellulosic fibers and a surface of said fabric, and applied at a solid loading percent of 15% or less.

An absorbent article comprising:
- an inner layer that rests against the skin of the user when the article is in use, said inner layer comprising a fabric of cellulosic fibers treated with at least one hydrophobic treatment selected from the group of:
- blending with synthetic fibers;
- leaving at least a portion of said cellulosic fibers unbleached so as to leave inherent lignin present;
- and
- applying a hydrophobic agent to at least one surface of said cellulosic fibers, such agent being applied to at least one of a surface of said cellulosic fibers and a surface of said fabric, and applied at a solid loading percent of 15% or less.

An absorbent article comprising:
- an outer layer that faces outwards from the skin of the user when the article is in use, said outer layer comprising a fabric of cellulosic fibers treated with at least one hydrophobic treatment selected from the group of:
- blending with synthetic fibers;
- leaving at least a portion of said cellulosic fibers unbleached so as to leave inherent lignin present;
- and
- applying a hydrophobic agent to at least one surface of said cellulosic fibers, such agent being applied to at least one of a surface of said cellulosic fibers and a surface of said fabric, and applied at a solid loading percent of 2.75% or less.
