A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100° C. to 200° C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

A method of making a natural fiber composite panel includes extracting bamboo fibers from bamboo and embedding the extracted bamboo fibers in a polymer matrix material. The bamboo includes bamboo fibers and lignin, and the step of extracting includes mechanically scraping the bamboo fibers to remove at least some of the lignin. In some cases, the bamboo is steamed, soaked in water, soaked in an acidic solution and/or soaked in an alkaline solution before mechanical scraping.

The invention relates to a former head of the kind which is used for forming, such as dry forming, of a fibrous web, where fibres are supplied to the former head mixed with air via at least one injection inlet. The former head comprising: a) a roller being rotatable in a rotation direction around a rotation axis and comprising: a roller surface surrounding the rotation axis, and a plurality of projections extending outwardly, such as radially outwardly, from the roller surface, b) a screen extending along at least part of the roller surface above the rotation axis, the roller surface and the screen defining therebetween a peripheral gap, and c) the injection inlet, wherein the injection inlet is positioned to conduct the mixture of the fibres and air into the peripheral gap in a delivery direction opposite or substantial opposite to the rotation direction of the roller.

A method of preparing fungal mycelium fiberboards is provided. First, 1-2 year-old fungal mycelium with a water content of 50-70% is cut into 2-3 cm lengths to obtain cut fungal mycelium. The cut fungal mycelium is then high-pressure steamed to soften it, resulting in the steamed fungal mycelium. The steamed fungal mycelium is mechanically defiberized into fibers and adhesive is added to obtain adhesive-applied fungal mycelium fibers. The adhesive-applied fungal mycelium fibers are then dried at 120-160° C., resulting in dried fungal mycelium fibers. The dried fungal mycelium fibers are then spread, leveled, and pre-pressed to obtain fungal mycelium fiberboard blanks, which are hot-pressed to form the final fungal mycelium fiberboard. This method uses low-cost, fast-growing fungal mycelium as a raw material, which replaces wood chips. The preparation process is simple and easy to promote. The resulting fungal mycelium fiberboard exhibits excellent performance in various indicators and is also environmentally friendly.
