Method of producing a fibrous web containing natural and synthetic fibres

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.
