  • Publication number: 20230212799
    Abstract: A method for consolidating a fibrous material of plant-based fibers, such as cellulose fibers and/or poly-lactic acid fibers, the method including: applying to the fibrous material an aqueous solution including a cellulose derivative, and/or a salt thereof, and an acid, the aqueous solution having a pH within the range of from 3 to 7, optionally within the range of from 3 to 6, optionally within the range of from 3 to 4.5; and drying the bonded fibrous material, optionally at 100° C. or higher. Also, a fibrous material formed by the method, an aqueous binder solution including a cellulose derivative, and/or a salt thereof, and an acid, and a nonwoven material including airlaid plant-based fibers being consolidated by a bio-based binder in the presence of a carboxylic acid, the bio-based binder being a cellulose derivative, and/or a salt thereof.

  • Patent number: 11000162
    Abstract: A multi-ply fibrous product includes at least two fibrous plies, such as a multi-ply nonwoven product, a tissue paper product or a hybrid thereof including at least two tissue paper plies and/or nonwoven plies including cellulosic fibers. At least two fibrous plies are bonded to each other by an aqueous adhesive composition including an adhesive component and a dermatologically acceptable acid, and optionally a salt thereof. A process for the manufacture of this multi-ply fibrous product includes (a) providing at least two fibrous webs, (c) applying an aqueous adhesive composition including an adhesive component and a water-soluble, dermatologically acceptable acid, and optionally the corresponding salt thereof, to at least one side of at least one fibrous web, d) superimposing at least two webs such that the aqueous adhesive composition is located between at least two superimposed webs, and e) bonding at least two webs together.

  • Patent number: 9637868
    Abstract: A bitumen containing composition, comprising bitumen and a phosphate compound, which is obtainable by the esterification of a polyhydric alcohol having at least three hydroxyl groups, with a carboxylic acid having 8-24 carbon atoms, preferably 12-22 carbon atoms, or a derivative thereof, wherein at least one but not all of the hydroxyl groups are esterified, provided that when the polyhydric alcohol has 5 or more hydroxyl groups then at least two but not all of the hydroxyl groups are esterified, followed by reacting the ester obtained with a phosphatising reagent; wherein the said composition is not a bitumen-in-water emulsion.

  • Patent number: 9534146
    Abstract: The present invention relates to a composition comprising bitumen and an alkoxylated amine, to a method for the production of such a composition, and to a method for paving a surface using such a composition. The present invention also relates to an preformulated additive package to be added to bitumen, comprising an alkoxylated amine and an anti-stripping agent.

  • Patent number: 9422453
    Abstract: The invention relates to an additive for a bitumen emulsion, which is a specific mixture of alkoxyiated compounds with low and high amounts of alkylene oxide units, in combination with a polyaluminum compound. Using this additive it is possible to prepare an aqueous slow-setting bitumen emulsion-aggregate mix suitable for cold paving of roads, parking places, sidewalks, and the like.
