A fabric or belt for a papermaking machine including a first layer that defines a web contacting surface and a second layer that supports the first layer. The first layer is made of extruded polymer and includes a plurality of first elements aligned in a first direction, a plurality of second elements aligned in a second direction and extending over the plurality of first elements, and a plurality of open portions defined by the plurality of first and second elements. The second layer is made of woven fabric. The first layer is bonded to the second layer so that the first layer extends only partially through the second layer and an interface formed between the first and second layers includes bonded and unbonded portions and airflow channels that extend in a plane parallel to the first and second layers.

A textured mask comprising a film. The film can have a first substantially continuously flat surface lying in a first plane and a second surface opposite the first surface lying in a second plane substantially parallel to the first plane. The second surface is interrupted by a plurality of cavities, each of the cavities having a first depth defined by a third surface lying in a third plane substantially parallel to the first and second planes. The depth of the cavities can be at a distance of from about 0.1 mm to about 5 mm from the second plane. The textured mask is at least partially coated with an opaque masking agent. The textured mask can make a correspondingly structured three-dimensional papermaking belt, which can make correspondingly structured three-dimensional fibrous structure.

According to an example aspect of the present invention, there is provided a cost-effective method of producing cellulose based films by introducing an intense water removal system to the process, and cellulose based films thereof having improved properties.

A seamed press felt formed from a base fabric having a CD width and an MD length with two opposing MD ends that are joined to form a continuous belt. MD oriented yarns form uniform loops at the two opposing MD ends that are interdigitated to define a pintle channel extending across the CD width. CD oriented yarns are connected to the MD oriented yarns, in a woven or non-woven construction. Loop open spaces are located within the loops on each of the two opposing MD ends in a seam region, with the loop open spaces being defined between a last one of the CD yarns at each of the two opposing MD ends and the pintle channel. At least one CD monofilament support yarn is located in the loop open spaces on each of the two opposing MD ends. The at least one CD monofilament support yarn has a diameter that is at least 1.6 times a diameter of the CD oriented yarns. A pintle extends through the pintle channel to form a seam.

Web material structuring belts that impart structure to a web material during a web material structuring operation and/or structured web material forming operation, method for making same and methods for using same to make structured web materials, for example structured fibrous structures, such as structured sanitary tissue products such as structured toilet tissue, structured paper towels and structured facial tissue are provided.

A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles being positioned along lines that are angled relative to the machine direction of the fabric. The angle of lines relative to the machine direction is between about 10° and about 30°. The method also includes drying the web to form the absorbent cellulosic sheet.

[Task] The object of the present invention is to provide an industrial two-layered fabric with a long durability which exhibits an excellent surface smoothness and excellent marking characteristics, while at the same time improving wear resistance characteristics to balance warps and wefts. [Solution to the Task] An industrial two-layered fabric formed by binding yarns, diameters of all of the upper surface side warps are set to be the same, diameters of all of the lower surface side warps are set to be the same, diameters of the lower surface side warps are set to be larger than diameters of said upper surface side warps, and at least one, or more than one of said upper surface side warps are woven with said lower surface side wefts to constitute binding yarns binding said at least one upper surface side fabric and said at least one lower surface side fabric.

The present invention relates to papermaking fabrics useful in the manufacture of paper products, such as tissue paper. Particularly this invention relates to a woven papermaking fabric that includes a stabilized weave providing a textured contacting surface. The woven papermaking fabric includes a plurality of warp and shute filaments woven together to provide at least one protuberance on the web contacting side of the fabric that extends longitudinally over at least five shute filaments. The at least one protuberance is stabilized by including an offset shute float weave pattern configured such that a majority of the shute filaments forming the at least one protuberance are woven in an anti-nesting configuration.
