A nanocomposite material with antimicrobial properties, based on cellulose packed with a mineral filler (zeolite) exchanged with silver, characterised in that the mineral filler is made up of Y-type zeolites, while silver occurs in a form bound with the zeolite matrix in the form of cations and, optionally, nanoparticles of reduced silver, as well as a method for preparation of such a material and its application for the wrapping of plants, works of art, archives and antique objects, as well as food, pharmaceuticals and animal fodder.

A composition including a first fiber derived from a first natural source, and a second fiber derived from a fruit, the second fiber being substantially free of surface active components. Surface active components may include oils, fatty acids, or other aliphatic and aromatic moieties that compromise edge wick performance. A process of manufacturing a paperboard product may include removing surface active components from fruit fiber to be included in manufacturing paper products to obtain a paper product with improved edge wicking properties.

The paper-like nanocomposite material can be used as capillary-porous elements of evaporative-type air-cooling units. As mineral fibers, glass fibers with a diameter of 0.4 m are used. These fibers are hydrophilic; they do not swell and have a large specific surface area. As a binder, sodium aluminate and aluminum sulfate are used at a predetermined ratio.

The material is made on traditional papermaking equipment using casting technique with a specified ratio of the above components.

The technical result is the obtainment of a paper-like material having high properties in height and time of water rise, moisture capacity and strength. The material is also characterized by thermic, chemical and biological stability, absence of toxicity and zero emission of substances harmful to the human body into the air, resistance of its properties to the effects of mold, fungi and microorganisms in the aquatic environment.

Provided is an antiviral transfer sheet manufacturing method for increasing the density of an antiviral agent or antibacterial agent in a surface which becomes an upper-most layer after transfer. In particular, a manufacturing method that eliminates the need for a large amount of an antiviral agent and the like, and the opacity of the layer having antiviral function is provided. A functional layer 37 including an inorganic antiviral agent powder and a hard coat agent is formed on one surface of a base material sheet 31 by disposing on the base material sheet the inorganic antiviral agent powder 33, and positioning the hard coat agent 34 in layer shape from over the inorganic antiviral agent powder 33. Then, an adhesive layer 39 is formed on the functional layer 37 in contact with the functional layer 37 or via another layer, thereby manufacturing an antiviral transfer sheet 11.

The present technology is directed to fluff pulps with improved odor control as well as methods of making such fluff pulps. A fluff pulp is provided that includes a bleached kraft fiber and a copper ion content from about 0.2 ppm to about 50 ppm by weight of the bleached kraft fiber. The bleached kraft fiber includes a length-weighted average fiber length of at least about 2 mm, a copper number of less than about 7, a carboxyl content of more than about 3.5 meq/100 grams; an ISO brightness of at least 80; and a viscosity from about 2 cps to about 9 cps.

Process for the surface treatment of a titanium dioxide pigment, characterized in that it comprises the following steps: an aqueous suspension of titanium dioxide pigments is formed, in a first step, a layer of alumina phosphate is precipitated on the surface of the pigment, in a second step, a layer of alumina is precipitated over the first layer of alumina phosphate, and in an optional third step, a layer of magnesium oxide is precipitated on the layer of alumina. Titanium dioxide pigments made by the disclosed process and method using said pigments in paper manufacturing are also disclosed.

Disclosed are: a method capable of preparing, in large-scaled quantity, nonspherical/asymmetric fine particles in which the physical factors (for example, size, shape, structure, etc.) of a fine wire (for example, glass-coated metal microwires) are controlled, through a convergence of nano technology (NT) and laser machining technology; and a use thereof applicable to various fields including bioassay and security.

A coated paper material comprising a paper substrate coated with a composition comprising at least one acrylic binder having a Tg of 3 C. or lower and at least one inorganic filler having a BET specific surface area in the range of 1.0 to 30.0 m.sup.2/g, wherein the dry weight ratio of the at least one acrylic binder to the at least one inorganic filler is between 15:100 and 20:100.
