An oil repellent agent including a modified natural product having at least one hydroxyl group, wherein a hydrogen atom of the hydroxyl group is replaced with an R group represented by —Y—Z, wherein Y represents a direct bond, —C(═O)—, —C(═O)—NR′— or —C(═S)—NR′—, where R′ represents a hydrogen atom or a C.sub.1 to C.sub.4 alkyl group); and Z represents a hydrocarbon group having 1 to 40 carbon atoms and optionally having a substituent or a polysiloxane. The natural material is a natural product other than starch and preferably is a monosaccharide, a polysaccharide, glycerin or polyglycerin. Also disclosed is a textile product to which the oil-resistant agent is attached, an oil-resistant paper and a method of treating paper with the oil-resistant agent.

An embodiment of the present disclosure provides a smoking article including a smoking material portion which is wrapped with a smoking material wrapper, a filter portion which has an upstream end combined with the smoking material portion and is wrapped with a filter wrapper, and a tipping paper which wraps around the filter portion and at least a portion of the smoking material portion so that the smoking material portion and the filter portion are combined, wherein a design printing layer, an overprint (OP) coating layer, and a sweetener coating layer are disposed on a surface of the tipping paper.

A system comprising a pulper configured to (i) accept surfactant, a liquid and fiber stock and (ii) generate a foam that suspends the fiber stock, wherein the foam has a half-life; a headbox configured to receive the foam-suspended fiber stock from the pulper and displace the foam-suspended fiber stock onto a forming wire, wherein a time it takes the foam-suspended fiber stock to move from the pulper to the headbox is less than the half-life; and a foam return device that removes at least some of the foam from the forming wire and returns the at least some of the foam to the pulper.

A process is provided for making a fluff pulp sheet, comprising contacting at least one cationic trivalent metal, salt thereof, or combination thereof with a composition comprising fluff pulp fibers and water at a first pH, to form a fluff pulp mixture; forming a web from the fluff pulp mixture; and applying at least one debonder surfactant to the web and raising the pH to a second pH, which is higher than the first pH, to make the fluff pulp sheet. A fluff pulp sheet is also provided, comprising a web comprising fluff pulp fibers; at least one cationic trivalent metal, salt thereof, or combination thereof; at least one debonder surfactant; and a fiberization energy of <145 kJ/kg. Products and uses of the fluff pulp sheet are also provided.

The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.

In a method for making a flexible material, a sheet of graphene oxide-composite paper is subjected to an environment having a relative humidity above a predetermined threshold for a predetermined amount of time. At least one expansion cut is cut in the sheet of graphene oxide-composite paper. A flexible conductive material includes a sheet of graphene oxide-composite paper defining at least one cut passing therethrough and formed it a kirigami structure. A region of the sheet of graphene oxide-composite paper includes reduced graphene oxide.

The present invention is directed to a non-moisturizing high-grade type tissue paper having excellent softness wherein the polyol applied to the two-ply tissue paper is not applied by external addition. In various embodiments, the tissue paper has a basis weight per ply of 14.0 to 17.0 g/m.sup.2, a paper thickness for two plies of 160 to 220 μm, and a water content of 4.0 to 9.0% by mass, contains 0.15 to 0.45% by mass of an oily component to be extracted with diethyl ether, and has a bending rigidity of less than 0.006 gf.Math.cm/cm in CD (cross direction) and a bending recovery force of less than 0.005 gf.Math.cm/cm in CD.
