A process for the production of composite materials comprising nano-fibrillar cellulose gels, by providing cellulose fibres and at least one filler and/or pigment, combining the cellulose fibres and the at least one filler and/or pigment, fibrillating the cellulose fibres in the presence of the at least one filler and/or pigment until a gel is formed, subsequently providing at least one further filler and/or pigment and combining the gel with the at least one further filler and/or pigment.

Methods are provided for defoaming water used in processing of various products such as cellulose or wood-based products or in food processing which is formed by reacting a fatty acid with a compound selected from the group consisting of ammonia, sodium, potassium and combinations thereof so as to form a water soluble soap, dispersing the water soluble soap in water, and homogenizing the dispersed water soluble soap with hydrophobic oil or hydrocarbon oil to produce the emulsion. Methods for preparing an emulsion used in this process are also provided. The emulsion is advantageous in that it can improve water resistance and/or reduce the use of water resistant additives during processing of cellulose or wood-based products or food-grade products.

A method for producing a microbial cellulose pulp for the production of viscose dope, the method comprising the step of: exposing a microbial cellulose to a volume of water to form the microbial cellulose pulp for the production of viscose dope, wherein the cellulose concentration in the microbial cellulose pulp is less than 0.040 g of cellulose per mL of pulp.

The invention relates to transfer paper for sublimation printing, having one or more alkaline earth salts on at least one face thereof.

A board including a plurality of layers having a different composition. At least one of the layers is based on MgO and MgChloride and/or at least one of said layers is based on MgO and MgSulphate. Methods for manufacturing such boards, and methods for manufacturing coated panels include such board.
