摘要： 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.

摘要： A water-dispersible composite structure, which comprises one or more layers, and a method of producingthe same. At least a part of the layers is formed by a fibrousweb or sheet containing 50–90 partsby weight of wood fibersand10–90partsby weight of annual or perennial plant fibersand/or10–50 partsby weight of synthetic short-cut fibers, and 0.1–20 % by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.

摘要： 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(12) consists mainly of natural fibers and a second, heat-sealing layer (14) located on top of the first layer. The heat- sealing layer (14) consists mainly of synthetic thermoplastic fibers or particles. According to the present method, the heat-sealing layer (14) is brought onto the first layer (12) 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.
