Abstract
The embossed multi-ply tissue products have improved bulk, softness, strength, embossment clarity and/or embossment height. The multi-ply tissue products comprise a first tissue ply having a plurality of embossments arranged in an open first pattern such as open, continuous line elements, which may be substantially oriented in the cross-machine direction (CD). The second ply of the multi-ply tissue product have a plurality of micro-embossments disposed in a second pattern. The first and second embossing patterns are such that when the first and second plies are joined to form the product the first and second patterns are not in registration with one another.

A multi-ply tissue product comprising a first tissue ply and a second tissue ply arranged in facing relation with one another, the first tissue ply having an outer surface and a plurality of first embossments disposed thereon in a first open embossing pattern consisting of a plurality of dot embossments arranged to form a plurality of continuous, substantially CD-oriented, wave-like line elements the second tissue ply having an outer surface and a plurality of second micro dot embossments disposed thereon at a density of at least about 25 embossments per square centimeter of ply surface area (embossments/cm2) in a second embossing pattern covering from 6 to 15 percent of the second ply outer surface, wherein the first and second embossing patterns are not in registration with one another when the plies are brought into facing arrangement with one another and wherein the tissue product has a basis weight from about 35 to about 65 grams per square meter (gsm).
A multi-ply tissue product comprising:
- a) a first ply having an outer surface and a first embossing pattern disposed thereon, the first embossing pattern consisting of a plurality of dot embossments arranged to form a plurality of continuous, substantially CD-oriented, wave-like line elements, each of the plurality of CD-oriented, wave-like line elements spaced apart from one another in the MD;
- and
- b) a second ply having an outer surface and a second embossing pattern disposed thereon, the second embossing pattern comprising a plurality of micro-embossments having a density of at least about 50 embossments/cm2 and covering at least about 6 percent of the second ply outer surface,
- wherein the first and second embossing patterns are not in registration with one another when the plies are brought into facing arrangement with one another.
A method of producing a tissue product comprising the steps of:
- a) providing a first embossing station with a first embossing roll having a first embossing pattern comprising a plurality of dot protuberances disposed in a first open embossing pattern consisting of a plurality of substantially CD-oriented wave-like line elements and a first counter roll, the first embossing roll and first counter roll defining a first nip there between;
- b) providing a second embossing station with a second embossing roll comprising a plurality of protuberances having a height from about 0.8 to about 1.2 mm and disposed in a second embossing pattern having a density of at least about 50 protuberances/cm2 and covering from 6 to 15 percent of the embossing roll surface and a second counter roll, the second embossing roll and second counter roll defining a second nip there between;
- c) directing a first tissue ply into the first nip to emboss the first tissue ply with the first open embossing pattern;
- d) directing a second tissue ply into the second nip to emboss the second tissue ply with the second embossing pattern;
- and
- e) joining the first and second tissue plies together in facing arrangement to one another to form a multi-ply tissue product, wherein the first and second embossing patterns are not in registration with one another.
