    • The invention relates to a method for manufacturing cellulosic material, the method comprising: introducing cellulose fibers as cellulosic raw material (1) to a system, and conveying the cellulose fibers (1) to an extruder (6) comprising a mixing part (6a, 6b) and/or a refining part (6d). The method further comprises dosing at least one chemical to the system before the extruder (6) and/or in the extruder (6) and performing a reaction between the cellulose fibers and the chemical(s) at least partly in the extruder (6), wherein the reaction is performed at a consistency of at least 40%, and/or dosing at least one chemical to the system before the extruder (6) and/or in the extruder (6) and mixing the cellulose fibers and the chemical(s) in the mixing part (6a, 6b) of the extruder (6), wherein the mixing step is performed at a consistency of at least 40%,and/or refining the introduced cellulose fibers at least partly in the refining part (6d) of the extruder (6), wherein the refining step is performed at a consistency of at least 5%. The invention further relates to a system for manufacturing cellulosic material. The invention further relates to use of the produced cellulosic material in the manufacture of fibril cellulose pulp.

    • The invention relates to a method for manufacturing a product (1 ) of natural fibre composite, the method comprising preparing a raw material mixture (4) which comprises at least 60 wt-%, advantageously at least 80 wt-% of natural fibres, and 1 to 40 wt-%, advantageously 10 to 20 wt-% of a binding agent. The method further comprises bringing said raw material mixture (4) in connection with a manufacturing mould (2), the manufacturing mould comprising a first surface (2a) and a second surface (2b). Subsequently, a blank (3) is formed of said raw material mixture (4) onto the first surface (2a) of said manufacturing mould (2), the blank substantially having the shape of the product of natural fibre composite to be formed, the forming of the blank (3) of the raw materials (4) taking place by the effect of a pressure difference across the manufacturing mould (2) in such a way that the pressure is substantially greater on the side of the first surface (2a) of the manufacturing mould than on the side of the second surface (2b) of the manufacturing mould. The method finally comprises finishing the blank (3) as a product (1 ) of natural fibre composite. The invention also relates to a corresponding system and a product of natural fibre composite.
    • 本发明涉及天然纤维复合材料制品(1)的制造方法,该方法包括制备原料混合物(4),其包含至少60重量%,有利地至少80重量%的天然纤维,以及 1至40重量%,有利地10至20重量%的粘合剂。 该方法还包括使所述原料混合物(4)与制造模具(2)相连,所述制造模具包括第一表面(2a)和第二表面(2b)。 随后,将由原料混合物(4)形成的坯料(3)放置在所述制造模具(2)的第一表面(2a)上,坯料基本上具有要形成的天然纤维复合材料的形状, 通过横跨制造模具(2)的压力差的方式形成原料(4)的坯件(3),使得第一表面(2a)侧的压力基本上较大, 比制造模具的第二表面(2b)侧。 该方法最终包括将作为天然纤维复合材料的产品(1)的坯料(3)整理。 本发明还涉及天然纤维复合材料的相应系统和产品。
