    • 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.
    • 本发明涉及一种制造纤维网的方法,该纤维网包括由天然纤维和可能的合成纤维组成的纤维基质。 根据本方法,由天然纤维和可能的合成纤维制备水性平面纤维层,所述层包含水相和纤维相,并干燥该层以除去水相,在这种情况下 天然纤维和可能的合成纤维一起形成纤维基质。 根据本发明,将粘合剂施加到含水纤维层上,在形成纤维之间的氢键之前,允许粘合剂至少部分地在纤维之间经由水相渗透。 通过本发明,可以制造这样的具有塑性特性(例如良好的断裂韧性,抗撕裂性和拉伸性)的纤维素或木质纤维素基纤维产品。
