  • Patent number: 7422660
    Abstract: Method of producing a nonwoven material, includes forming a web of continuous filaments on a forming member (12) and applying a wet- or foam formed fiber dispersion containing natural fibers and/or synthetic staple fibers on top of the continuous filaments. A fibrous web is thus formed containing continuous filaments and natural fibers and/or synthetic staple fibers, this web subsequently being hydroentangled to form a nonwoven material. Moisture is applied to the web of continuous filaments under a low pressure before laying the wet- or foam formed fiber dispersion on the web of continuous filaments, avoiding any substantial bonding between the filaments in the web.
    Type: Grant

  • Publication number: 20050091811
    Abstract: Method of producing a nonwoven material, wherein a fibrous web containing continuous filaments and natural fibers and/or staple fibers is formed on a forming member (12) and subsequently hydroentangled to form the nonwoven material. The fibrous web is transferred to an entangling member (16) while subjecting the fibrous web to foreshortening and subsequently hydroentangling the foreshortened fibrous web, thus forming a composite material (19) wherein the continuous filaments are well integrated with the rest of the fibers.

  • Patent number: 6596127
    Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which has been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web during the passage through the press nip is given a three-dimensional pattern of alternating raised and recessed portions either by means of a pattern wire, band or belt and/or by a pattern on the heated roll (13) and where the paper web (10) after said press nip (12) is led around an essential part of the periphery of the heated roll (13) in order to provide an additional drying of the paper web while this is still in contact with said three-dimensional pattern.

  • Patent number: 6503370
    Abstract: Method of producing paper having a three-dimensional pattern of alternating raised and recessed portions which is given the paper in connection with impulse drying, at which the wet paper web is passed through at least one press nip (12) comprising a rotatable roll (13) which is heated and that the paper web when passing through the press nip is given a three-dimensional pattern either by means of a pattern wire (11) and/or by the fact that the heated roll (13) is provided with a three-dimensional pattern, and where the wet paper web (10) before entering said press nip (12) is given a basis weight variation in a non-random pattern.

  • Patent number: 6454905
    Abstract: Method of producing an impulse dried paper having a three-dimensional pattern of alternating raised and recessed portions, which have been provided in connection with impulse drying, at which the wet paper web (10) is passed through at least two press nips (12a,b), each comprising a rotatable heated roll (13a,b) which is heated and that the paper web during the passage through the press nips is given a three-dimensional pattern of alternating raised and recessed portions either by means of a patterned wire (11′), -band or belt and/or by a pattern on the heated roll (13a,b).

  • Patent number: 6444089
    Abstract: Method of producing a paper having a three-dimensional pattern of alternating raised and recessed portions which is given the paper in connection with impulse drying. The paper web has a varying material composition as seen in its thickness direction, so that it at least in an outer layer contains an amount of a material that softens, melts or hardens in the temperature interval 100-400° C. or in some other way contributes in stabilizing the pattern structure that has been given the paper. It is further referred to an impulse dried paper produced according to the method.
