Abstract: A smoking article (10, 30, 40, 50, 70) with variable ventilation comprises a mouthpiece (12) circumscribed by a first wrapper (24) and a second wrapper (25). The first wrapper (24) and the second wrapper (25) are substantially air impermeable and are movable relative to one another between a low ventilation configuration and a high ventilation configuration. The mouthpiece (12) comprises a first airflow pathway (18, 19) through the first wrapper (24) or the second wrapper (25) and a second airflow pathway (26) through the first wrapper (24) or the second wrapper (25). In the low ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) is restricted and airflow into the mouthpiece (12) through the second airflow pathway (26) is substantially unrestricted. In the high ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) and the second airflow pathway (26) is substantially unrestricted.

Abstract: The invention provides methods and compositions for increasing the strength of a paper sheet. The method involves adding to the paper sheet an amine containing polymer. The amine containing polymer interacts with materials such as GPAM or starch to make the paper stronger in terms including tensile strength, surface strength and bulk strength.

Abstract: A method for producing antimicrobial paper pulp is provided. The method includes steps of obtaining paper pulp, reducing water content and temperature of the paper pulp, and refining the paper pulp having reduced water content and temperature to improve properties of the paper pulp. The refining may be performed using a refiner with rotating and stationary cutters. The nanocomposite suspension may be added to the refined paper pulp to produce antimicrobial paper pulp. The antimicrobial paper pulp may be drained and pressed to produce paper by applying oil to reduce moisture content of the paper. The paper may be dried without using vapor.

Abstract: 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.

Abstract: Systems and methods are provided for producing continuous buckypapers. The systems may permit the in-line characterization and crosslinking of the continuous buckypapers. The systems include roll-to-roll systems in which a continuous buckypaper is created and then separated from the filter paper in an automated process.

Abstract: A mineral composition and related methods may include a mineral treated with a styrene-based polymer. The mineral treated with a styrene-based polymer may be used for a coating on a paper product having a first Cobb value that is less than a second Cobb value of the paper product with the coating devoid of the mineral composition.

Abstract: The present invention concerns a process for preparing self-binding pigment particles from an aqueous suspension of calcium carbonate containing material, wherein an anionic binder and at least one cationic polymer are mixed with the suspension.

Abstract: The present invention generally relates to tissue webs and products, which generally have a basis weight less than about 80 grams per square meter (gsm) and a sheet bulk greater than about 5 cubic centimeters per gram (cc/g) comprising a blend of conventional papermaking fibers and high carbohydrate fillers. Surprisingly, the fillers may displace a relatively large amount of conventional papermaking fibers, such as hardwood kraft pulp, without negatively affecting important tissue properties such as caliper, bulk, slough, absorbent capacity and softness. In fact, in certain instances the use of fillers actually improves tissue properties.

Abstract: The present disclosure is directed to a continuous process for preparing cellulose reactive adducts of polyvinylamide.

Abstract: A method of increasing the drainage performance of a pulp slurry during the manufacture of paper products by adding (a) at least one microfibrillated cellulose and (b) at least one associative polymer or at least one branched or crosslinked copolymer to the pulp slurry. This addition occurs before the dewatering step where the pulp slurry is formed into a fibrous mat.

Abstract: A sheet manufacturing apparatus includes a drum unit having a plurality of openings, a housing unit covering the drum unit, a transport unit on which a material containing fibers passing through the openings is accumulated as a web and which transports the accumulated web, a first roller that abuts the web transported by the transport unit, and a first seal unit that is provided on a first side wall of the housing unit and comes into contact with the first roller.

Abstract: Smoking articles including filter elements formed from two or more fibrous inputs with different physical properties are provided. The two or more fibrous inputs are provided in the form of staple fibers, which are at least partially entangled with each other to form a mixed fiber sliver. The mixed fiber sliver includes a first plurality of cellulose acetate staple fibers blended with a second plurality of staple fibers comprising a polymeric material different from the first plurality of staple fibers, such as staple fibers of a degradable polymeric material. The entangled fibers of the mixed fiber sliver may be sufficiently separated from one another such that blooming operations typically required in filter element production may not be necessary prior to incorporating the mixed fiber sliver into a filter element. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

Abstract: The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.

Abstract: An oral tobacco pouch product includes a pouch wrapper formed of a web having a longitudinal integrated fin and lap seal.
