Abstract

The present invention relates to a foam composition comprising cellulose fibres, a water-soluble thickener, and surfactants. The foam composition can be used for preparing a foam that can be dried without constraints to form three-dimensional objects.

Claims (1)

1. A wet foam composition comprising: a) from 71-95 wt% cellulose fibres, as calculated on the total weight of solid content of the composition, b) from 4-24 wt% of a water-soluble thickener, as calculated on the total weight of solid content of the composition, and c) at least two surfactants; wherein the wet foam composition has a total solid content from 12-40 wt% as calculated on the total weight of the wet composition. The wet foam composition according to claim 1, wherein one of the surfactants is an anionic surfactant having an apparent pKa of from 3.2 to 3.8 in a solution having a pH of from 7 to The wet foam composition according to any one of claims 1 to 2, wherein one of the surfactants is a co-surfactant. The wet foam composition according to claim 3, wherein the co-surfactant is selected from surfactants having an apparent pKa of at least 8 in a solution having a pH of from 7 to 9; or amphoteric betaines. The wet foam composition according to claim 3 or 4, wherein the molar ratio between the anionic surfactant to co-surfactant is from O.2:1-3: The wet foam composition according to any one of claims 1 to 5, wherein the total amount of the at least two surfactants is 0.6-5 wt%, as calculated on the total weight of solid content of the composition. The wet foam composition according to any one of claims 1 to 6, wherein the cellulose fibres are selected from wood pulp; regenerated cellulose fibres; and plant fibres; preferably selected from softwood Kraft bleached pulp, chemical- thermomechanical pulp and dissolving pulp or a combination thereof. The wet foam composition according to any one of claims 1 to 7, having a density from 140-500 kg/mg. The wet foam composition according to any one of claims 1 to 8, having a yield stress of from 20 to 200 Pa. A method for the preparation of a wet foam composition according to claim 1, comprising a) disintegrating cellulose fibres in water to obtain a slurry of cellulose fibres; b) adding a water-soluble thickener to the slurry obtained in a) to obtain a mixture of water-solu ble thickener and cellulose fibres in water; c) adding at least two surfactants to the mixture obtained in b) to obtain a fibre suspension; d) aerating the suspension obtained in c) to obtain a wet foam, wherein the wet foam comprises 10-38 wt% cellulose fibres, 0.5-10 wt% of the water-soluble thickener, and 0.1-2 wt% surfactants, as calculated on the total weight of the wet foam, and wherein the wet foam has a density of from 140- 500 kg/m3 and a yield stress of from 20 to 200 Pa. The method according to claim 10, wherein the water-soluble thickener is added to the slurry obtained in step (a) as a solution comprising 4-12 wt% of the thickener. A wet foam obtained with the method according to any one of claims 10 to 24
