摘要:
The invention relates to a method for forming a film-forming hydrophobic layer on a substrate, which method includes: fanning an aqueous suspension of cellulose nanofibers, CNF; forming, in water and with a water-immiscible solvent having an evaporation temperature below that of water, a cationic nanoemulsion of a substance forming covalent bonds with the cellulose; mixing the suspension and the nanoemulsion such as to produce a mixture resulting from an adsorption of said substance by the CNF; coating a substrate with said mixture; and proceeding to an annealing suitable for grafting said substance to the CNF.

摘要:
A planar support with two faces on which hand writing and hand drawing may take place includes an assembly of two fibrous layers having the respective faces, and a thermoplastic polymer preparation between the two fibrous layers. The thermoplastic polymer preparation makes the support opaque to direct transmission of light. The thermoplastic polymer preparation is filled with carbon black, chalk, and/or titanium dioxide to scatter and attenuate light in the thermoplastic polymer preparation.

The disclosure provides tissue webs, and products incorporating the same, where the webs comprise wood and bamboo fibers. More specifically the disclosure provides soft and durable through-air dried tissue webs comprising at least about 10 percent bamboo fiber by weight of the web. In the through-air dried tissue webs of the present disclosure, bamboo typically replaces high average fiber length wood fibers, which increases the bulk of the through-air dried web without negatively effecting softness or durability.

摘要:
A method for producing a fiber web (W) in which method the fiber web (W) is calendered in at least one nip (NA) of a calender (20A). The fiber web (W) is cooled at least partially by moisturizing evaporating cooling by a moisturizing evaporating cooling unit (10) before the fiber web is calendered and moisture is absorbed during 10-500 ms. A production line for producing fiber webs (W) has a calender (20A) with a calendering nip (NA). The production line for fiber webs, in particular board webs, has a fiber web machine (50), in particular a board machine, with a head box, a wire section, a press section and a drying section, and at least one moisturizing evaporating cooling module (10), and a hard nip calender (20A) with a thermo roll, which has a surface temperature at least 120° C., and a reel-up (40).
