An absorbent paper sheet is treated with an aqueous wax dispersion such
that the sheet includes a fused wax and emulsifier residue in an amount
of from about 1 to about 20 weight percent of the sheet based on the
combined weight of the fiber, wax residue and an emulsifier residue in
the sheet. The fused wax emulsion operates to make at least one surface
of the sheet laterally hydrophobic, exhibiting a moisture penetration
delay of at least about 2 seconds and less than about 40 seconds as well
as a typical contact angle with water at one minute of at least about 50
degrees. There is thus provided absorbent products which exhibit both
absorbency and resistance to moisture penetration. The treated sheet
further exhibits microbial barrier properties, impeding transfer of
bacteria, for example, through the sheet. There are produced tissue
products which resist moisture penetration from propelled liquids as well
as sequester sorbed liquids in the interior of the tissue.
