摘要:
Disclosed are multi-ply embossed tissue products having improved softness, strength, embossment clarity and/or embossment height compared to prior art embossed tissue products. The multi-ply tissue products may comprise an embossed tissue ply having a basis weight less than about 25 grams per square meter (gsm) and relatively deep embossments, such as an embossment height from about 500 to about 1,000 μm and relatively narrow bottom portions compared to top portions. The combination of these elements provides an aesthetically pleasing and well-defined embossment, while improving important tissue product properties such as sheet and roll bulk and softness.

Disclosed are embossed multi-ply tissue products having 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 products further comprise a second ply having 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 sheet of absorbent paper includes at least one first and one second embossed plies of tissue having protuberances on the inward-facing side of the sheet corresponding to cavities on the outer side, with a first type of protuberances on the first ply, the first type of protuberances on the second ply, at least some of the first type of protuberances of the first ply contacting at least some of the first type of protuberances of the second ply, the first ply and the second ply include a second type of protuberances of frustoconical form, the first type of protuberances being partly adjacent to the second type of protuberances, the first type of protuberances of the first ply are aligned in a first direction and the first type of protuberances of the second ply are aligned in a second direction, the two directions forming a non-zero angle alpha between them.

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.

Multi-layer bags may be formed to include first and second sidewalls joined along a first side edge, an opposite second side edge, and a closed bottom edge. The first and second layers may be non-continuously laminated together in discrete sections to include bonded regions in which the layers are bonded and unbonded regions in which the layers are not bonded. Such a bag may be described as a “bag-in-a-bag” type configuration in which the inner bag is non-continuously bonded to the outer bag. The inventors have surprisingly found that such configurations of non-continuous bonding provides increased and unexpected strength properties to the multi-layer films and bags.
摘要:
A method of embossing an absorbent web with a machine direction undulatory structure is described. The web has a plurality of ridges extending in its machine direction occurring at a frequency, F, across the web and the method includes providing the web to an embossing station where the web is embossed between a first and second embossing roll, each of which rolls may be provided with a plurality of embossing elements configured to define a plurality of embossing nips. At least a portion of the embossing nips are substantially oriented in a cross-machine direction with respect to the web and have a cross direction length, L. The product F×L is from about 0.1 to about 5.
摘要:
An embossing system is provided for embossing a web having a first embossing roll having embossing elements and a second embossing roll having embossing elements, wherein at least a portion of the embossing elements of the first and second embossing rolls are substantially oriented in the cross-machine direction. The embossing roll may be crowned, may have alignment means, and may be provided with precision gearing.
摘要:
An embossing system for embossing and perforating at least a portion of a web is provided comprising a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein the elements of the first and second embossing rolls define perforate nips for embossing and perforating the web and wherein at least a predominate number of the perforate nips are substantially oriented in the cross-machine direction. Moreover, substantially all of the nips defined by the embossing elements of the first and second embossing rolls can be substantially oriented in the cross-machine direction. Further, the cross-machine embossing elements are at an angle of about 85null to 95null from the machine direction.

An embossing and laminating machine is described which comprises a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3) disposed with a first pitch in a first direction (Lx3) of alignment and with a second pitch in a second direction (Ly3) of alignment, the said first and the said second direction of alignment forming between them an angle (&agr;) other then zero; a second embossing cylinder (5), with its axis (A5) parallel to the axis (A3) of the first embossing cylinder (3), and with a surface provided with a second set of protuberances (P5) disposed with the said first pitch in a third direction (Lx5) of alignment and with the said second pitch in a fourth direction (Ly5) of alignment; and a first and a second pressure roller (7, 9) interacting with the said first and the said second embossing cylinder (3, 5) respectively. The first and the third direction of alignment (Lx3) are inclined with respect to the axes (A3, A5) of the corresponding embossing cylinders (3, 5) such that, in the lamination nip, there is only partial corresponding between the protuberances of one cylinder and the protuberances of the other cylinder.
摘要:
A method of embossing a sheet of non-woven fibrous web, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.
