摘要： 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.

摘要翻译： 用水性蜡分散体处理吸收性纸张，使得片材包含熔融蜡和乳化剂残余物，其量为纸的约1至约20重量％，基于纤维，蜡残余物和 乳化剂残留在片材中。 熔融蜡乳液操作以使片材的至少一个表面横向疏水，表现出至少约2秒且小于约40秒的水分渗透延迟，以及与一分钟至少约一分钟的水的典型接触角 50度。 因此，提供了吸收性产品，其具有吸湿性和耐潮湿渗透性。 经处理的片材还具有微生物阻挡性能，阻止例如通过片材的细菌转移。 产生的组织产品抵抗来自推进液体的水分渗透以及组织内部的螯合吸附液体。

摘要： An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
