Abstract: The present invention relates to multi-layer fiber products and a method of manufacturing these kinds of products. The present product comprises a first layer consists mainly of natural fibers and a second, heat-sealing layer located on top of the first layer. The heat-sealing layer consists mainly of synthetic thermoplastic fibers or particles. According to the present method, the heat-sealing layer is brought onto the first layer already during the web forming process, the first and the second layers being formed and joined together in a foam forming process. With the present invention, it is possible to decrease the amount of plastic materials in packaging materials having heat-sealing properties.

Abstract: A method of producing a fibrous web, according to which method a fibrous web is formed of foamed fibre dispersion, by using foam forming. According to the present invention, the foamed fibre dispersion comprises recycled textile fibres and possibly natural fibres or synthetic fibres, or a mixture thereof, in which case, of the fibres in the fibre layer, at least 30% % by weight, in particular at least 50% by weight, is sourced from recycled textile fibres. The present invention generates a product with which it is possible to replace, for example, plastic in bag and package applications. The present product is also suitable, for example, for various textile and furniture applications.

Abstract: Fiber sheets, structures comprising the fiber sheets and the use of the sheets. The invention further relates to biodegradable and/or recyclable products comprising the fiber sheets, useful in replacing non-biodegradable products.

Abstract: The present invention relates to a method of manufacturing a fibre web which includes a fibre matrix that is comprised of natural fibres and possibly synthetic fibres. According to the present method, an aqueous, planar fibre layer is prepared from the natural fibres and possible synthetic fibres, which layer comprises an aqueous phase and a fibrous phase, and which layer is dried in order to remove the aqueous phase, in which case the natural fibres and possible synthetic fibres together form a fibre matrix. According to the present invention, binder is applied onto the water-containing fibre layer, which binder is allowed to penetrate via the aqueous phase at least partially in between the fibres, before the hydrogen bonds between the fibres form. With the present invention, it is possible to manufacture such cellulose or lignocellulose-based fibre products which have plastic-like properties, such as good fracture toughness, tear resistance and stretching.

Abstract: The present invention relates to a method of forming a molded fibrous product, comprising the steps of foaming an aqueous suspension of natural fibers, optionally in combination with synthetic fibers, to provide a first fibrous foam, a surfactant may be added to aid the foaming, feeding the fibrous foam into a mold, mechanically withdrawing a part of the water contained in the foam to produce a solidified, moist fibrous composition, and evaporating water from the solidified, moist fibrous composition to produce a dry fibrous product.

Abstract: A method for producing printed products, according to which method the surface of a sheet of paper or board is printed by the electrophotography technique or a similar printing method, wherein a dry finely-divided printing ink is transferred onto the printing base by means of an electric field. According to the invention, a paper or board is used the printing surface of which has a pigment-containing coating layer in which at least 20% of the pigment is made up of a hydrous pigment, such as gypsum, or in which at least 20% of the filler is made up of a hydrous filler, such as gypsum. When a gypsum pigment and/or a gypsum filler is used, the quality of the printed image is not sensitive to the control quantities used in the printing press. By means of the invention, a very regular print is indeed obtained, and so the invention is especially well suited for the printing of a sheet of a very matt paper or board.
