Total heat exchange element paper having excellent moisture resistance and gas barrier properties, comprising a substrate sheet and a moisture absorbent and colloidal silica both of which are adhered to the substrate sheet, wherein the substrate sheet contains natural pulp which has been beaten to a freeness specified in JIS P 8121-1:2012 of not lower than 80° SR and the colloidal silica is cationic colloidal silica.

The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet-pressed tissue products, having substantially higher per-ply basis weights, such as from about 14.0 grams per square meter or greater. Despite having relatively high per-ply basis weights, the products are generally soft and flexible, such as having a softness value (measured as TS7) less than about 10.0 and a Stiffness Index less than about 20.0. While being soft and flexible, the tissue products are durable enough to withstand use, such as having a geometric mean tensile (GMT) greater than about 1,000 g/3″.

A sealing strip and a sealing device for sealing a negative-pressure zone of a suction roller for a machine for producing or processing a fibrous web, such as a paper, board or tissue machine. The stealing strip has an upper face, which forms a sealing surface of the sealing strip, and the sealing strip includes a sensor unit, which has a first temperature sensor at a first distance from the sealing surface and a second temperature sensor at a second distance from the sealing surface. The first distance is smaller than the second distance. The sealing strip is formed of a base material and a protective material which is different from the base material, and the sensor unit is embedded, in particular cast, into the protective material.

Paper products can comprise a first plurality of fibers that are hardwood fibers and a second plurality of fibers that include softwood fibers and surface enhanced pulp fibers (SEPF). The paper product can include one or more first fiber layers that comprise the first fibers, at least one of the first fiber layer(s) defining one of opposing upper and lower surfaces of the paper product, and one or more second fiber layers that comprise the second fibers. When a tissue, by weight, between 50% and 80% of the tissue's fibers can be the first fibers and at least 20% of the tissue's fibers can be the second fibers. The tissue's basis weight can be less than or equal to 21 gsm per ply.

A power storage material is made by using a fiber material of cellulose molecules obtained from wood, plant fibers (pulp), and the like, and capable of storing electric power of direct current and alternating current, and an ultra power storage body has the power storage material. A power storage material includes a fiber mainly including a fiber derived from at least any one of wood, plant fibers (pulp), animals, algae, microorganisms, and microbial products, and having a large number of recesses and protrusions on a surface. The fiber is preferably crystallized/amorphous fibers, is preferably an amorphous fiber having an atomic vacancy, and preferably has a specific surface area of 10 m.sup.2/g or more. Preferably, the large number of recesses and protrusions have a diameter of 1 nm to 500 nm. Preferably, the electric resistance is 100 MΩ or more, and the electric capacity is 5 mF/cm.sup.2 or more

The present disclosure provides an aerosol-generating article including an aerosol generator including: an aerosol generator comprising an aerosol-generating material configure to vaporize into an aerosol; a tobacco filling part comprising an inner wrapper on which a plurality of folds are formed, and granules of a tobacco material attached to the plurality of folds such that a tobacco component is added to the aerosol passing through the tobacco filling part; and a thermally conductive wrapper wrapped around at least part of outer surfaces of the aerosol generator and the tobacco filling part, and configured to transmit heat to the aerosol-generating material and the tobacco material.

According to an embodiment, a stack-of-sheets package includes: a stack of sheets; a conductive sheet; and a package material. The stack of sheets is obtained by stacking printing sheets, each of the printing sheets having a printable surface and including a wireless tag. The conductive sheet is disposed at an end portion of the stack of sheets in a stacking direction of the printing sheets. The conductive sheet has a conductive region that overlaps with the wireless tag as viewed from the stacking direction. The package material packages the stack of sheets.

Clothing is provided for a machine for producing a fibrous web, in particular a paper, board or tissue web. The clothing has a substrate. The substrate has a top side, an underside, two side edges and a useful region between the two side edges. The useful region has a plurality of through-channels, which connect the top side to the underside of the substrate. An inner surface of at least one through-channel, preferably of the majority of all the through-channels, more preferably of all the through-channels in the useful region of the substrate, has a mean roughness depth that is greater than 4 μm, preferably greater than 6 μm, more preferably greater than 8 μm. The clothing of this type is produced using a laser.

A biodegradable food-grade polyvinyl alcohol (PVA) paper substrate and a method for making the same are provided. The method includes: providing a paper substrate; preparing a first coating material by rendering PVA with a degree of alkalization of 90%-100% and a molecular weight of 100,000-300,000 into an aqueous solution in which the PVA has a weight ratio of 3%-15%; preparing a second coating material by rendering sodium trimetaphosphate into an aqueous solution in which the sodium trimetaphosphate has a molar concentration of 0.05-1 Mol/l; forming a coating layer on a surface of the paper substrate; forming a surface cross-linked layer on the coating layer; and drying. The resulting PVA paper substrate is biodegradable, of food-grade quality, and resistant to water and grease, with a grease resistance higher than or equal to that corresponding to kit No. 6 in a TAPPI T559 pm-96 standard test.
