Document Type and Number:
Japanese Patent JP2002526687
Kind Code:
A
Abstract:
Method of producing an impulse dried wetlaid fibrous web-shaped material, such as paper or non-woven, having a three-dimensional pattern of alternating raised and recessed portions, which have been provided in connection with impulse drying, at which the wet fibrous web is passed through at least one press nip (12) comprising rotatable roll (13) which is heated and that the fibrous 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 patterned wire (11) and/or by a pattern on the heated roll (13) To the fibrous web there has been added a material that softens or melts in the temperature interval 100-400° C. and that at least the parts of the fibrous web that is located closest to the raised portions of the heated roll (13) are heated to such a high temperature that said material softens or melts and by that provides an increased amount of bonding points in the fibrous web. There is further provided a thermobonded impulse dried material produced by the method.
