SUBSTANCE: invention relates to fluff pulp sheets, methods of their manufacturing and application. The method of manufacturing fluff pulp sheet includes a contact of, at least, one cationic trivalent metal or zinc, or their salt, or their combination with a composition, which contains fluff pulp fibres and water with the first value pH<5 in order to form the first mixture. After that, carried out are: contact of, at least, one loosing SAS with the first mixture and increase of pH value to the second value pH≥5 in order to form a fluff pulp mixture. After that, cloth of fluff pulp mixture is formed and dried to produce a fluff pulp sheet. The invention also relates to the fluff pulp sheet, produced by the said method. Also claimed is the fluff pulp sheet, which includes cloth, containing fluff pulp fibres, at least, one cationic trivalent metal, its salt or their combination, at least, one loosing SAS, and has a defibration energy <145 kJ/kg. Also claimed are products and possible applications of the fluff pulp sheet.

EFFECT: obtained sheets and products possess improved physical-mechanical characteristics.

SUBSTANCE: invention relates to the technology of producing surface-active materials capable of forming and stabilising foam and emulsions, and can be used for coating, encapsulating and delivering medicines to places where activity thereof is realised, in household or personal hygiene, in the food industry, oil industry, agriculture, textile industry, construction, emulsion polymerisation, production of leather, plastic, cellulose pulp, paper and pharmaceuticals. The surface-active material contains fibre modified with chemical and physical agents in order to endow them with surface-active properties and provide them with a three-phase contact angle on the fibre/air/water or fibre/oil/water phase boundary between 60 and 120°. The fibre has an insoluble structure in form of solid particles and coefficient of proportionality ranging from more than 10 to 1000.

EFFECT: material has high stability and good biodegradation characteristics.

SUBSTANCE: napkin items, containing additive compositions, relate to cosmetic volume napkins, method of their production and sheet item. Napkin item with bulk of more than 3 cm3/g includes napkin cloth of cellulose fibres and additive composition, available on the first side of napkin cloth, which contains non-fibre olefin polymer, copolymer of ethylene-carbonic acid or their mixtures. In another version of napkin cloth the first side of paper cloth is creped after application of above specified additive composition. Napkin items are made by method including application of above specified additive composition onto the first side of napkin cloth, where napkin cloth comprises cellulose fibres, and creping of the first side of napkin cloth with creped surface, where additive composition helps napkin cloth to stick to creping surface. Sheet item comprises base cloth of cellulose fibre. Base cloth is hydraulically entangled cloth, coform cloth or air-laid cloth. Cloth also includes above-specified additive composition and has bulk of more than around 3 cm3/g.

EFFECT: improved strength of napkin cloth and/or cloth softness by touch without attendant issues of sticking.

Composition // 2347030

FIELD: textiles; paper.

SUBSTANCE: composition is meant for improving the softness of paper products. Composition includes: (i) oil, fat or wax; (ii) at least one non-ionic surfactant; (iii) at least one anion compound, selected from anionic micro-particles and anionic surfactant; (iv) at least one polymer, which is a cation, non-ionic or amphoteric, where the non-ionic surfactant is added to the amount from about 60 to 1000 weight fractions for 100 weight fractions of the polymer. Composition is used in the method of manufacturing paper (versions). Method includes adding the mentioned composition to a cellulose suspension or to a moist or dry paper fabric.

EFFECT: increase in the quality of the paper products due to the increase in its softness, low resistance to tearing and high speed of getting wet and reduction in energy for pulping.
