  • METHOD OF SPINNING FIBRES OR EXTRUSION, AND THE PRODUCTS OBTAINED
    Publication number: 20190032247
    Abstract: The invention relates to a continuous, scalable and parallelizable method for preparing strong and stiff fibres (filaments) or films. The fibre or film is prepared by utilizing hydrodynamically induced alignment of the constituents of a dispersion in combination with surface-charge controlled gel transition to produce fibres with a high degree of alignment of the constituents (polymer(s), fibrils etc.). The invention also relates to the fibres or films so formed.
    Type: Application

  • Single-step method for production of nano pulp by acceleration and disintegration of raw material
    Patent number: 9388529
    Abstract: The invention relates to methods of manufacturing nano pulp, wherein cellulose containing raw material is accelerated in a continuous gas and/or liquid flow, whereby the material is disintegrated and nano pulp is produced. The gas and/or liquid flow may be created by reduction of an elevated pressure in a reactor holding the cellulose containing raw material. The invention also relates to the nano pulp produced.

  • Method of forming a fibrous web
    Patent number: 7429307
    Abstract: In a method of forming a layered fibrous web, the method includes the steps of leading at least two different fiber suspensions through a head box (10), separating the fiber suspensions from each other by a blade device (18, 180), supplying the fiber suspensions to a web forming device (24) and forming a water layer having a transversely uniform flow at an outlet at the end of the blade device (18, 180), such that the water layer constitutes an extension of the blade device and thereby prevents mixing of the fiber suspensions. The blade device (18, 180) can be freely movable in a substantially vertical direction in order to permit an equalization of pressure between the fiber suspension layers separated by the blade device and thereby reducing wake effects downstream the edge of the blade device. A paper machine for carrying out the method is also disclosed.
