Definitions
- Tissue paper machine tissue paper produced therewith and method for producing such tissue paper
- the invention relates to the production of tissue paper, as is used, for example, as kitchen towels, handkerchiefs, facials, toilet paper, napkins and the like.
- the invention is based on the technical problem (object) of creating a machine and a method with which tissue paper with improved optical and haptic properties can be achieved.
- the solution according to the invention can be used to produce tissue paper which, by producing textile-like structures, gives a better visual and “haptic impression”.
- haptic impression is meant the subjective, sensory impression obtained with the hands, the “grip feeling”.
- a good combination of surface softness and knotty softness is appreciated. This is achieved by forming a tissue paper with a texture consisting of small zones of increased and reduced basis weight in the macro area. The areas with a lower basis weight oppose a deforming force with a lower resistance than the zones with a higher basis weight and thus shorten the length of the folded edges which arise during the curling. This means an improvement in softness, physically and sensorially.
- the drainage through the sheet forming screen in the Z direction is prevented or severely restricted.
- the fibers are concentrated in the zones of unhindered drainage.
- the zones with different grammages are essentially the only structural feature.
- the fibers show an orientation in the machine direction in the tissue paper. All conventional materials for the screens can be used, e.g. B. metal wire or plastic sieves. It is an object of the invention to produce flat paper. The paper should not adopt the structure of the screen in contact with the paper.
- the underlying texture sieve naturally lowers the overall drainage performance and should therefore be roughly patterned in order to keep the impairment of the drainage performance by the underlying texture sieve as low as possible.
- Areas of different basis weight are limited to the extent that the blocking of the drainage (by the texture of the second screen) in the Z direction is avoided by the water transport within the sheet forming screen in the X-Y direction. For the finest possible texture in tissue paper, this is
- the sieves have a wire diameter of 0.1 to 0.4 mm. A long one To avoid water transport in the X and Y directions, a wire diameter of less than 0.3 mm should be used. Less than 0.2 mm would be better. The best would be to use a wire diameter of less than 0.1 mm.
- the zones of increased basis weight in the tissue product are connected to one another in a network.
- the resulting influence on the strength is comparatively small or non-existent.
- the texture screens which produce paper with network-like zones of increased basis weight, can also be so-called "belts", in which a material is applied to a supporting fabric, which has a structure on the side in contact with the paper. Examples result from EP 0 135 231 B (production of pillows with a higher basis weight) and WO 93/00474 A (production of a continuous network with a higher basis weight).
- a tissue paper is created with linked zones of lower basis weight and resulting losses in strength.
- z. B. a film, belt, etc. can be used with a perforated pattern. Due to the comparatively small drainage zones in the connected zones of lower basis weight, a lot of material is concentrated. The result is a "pillow effect", which has a positive effect on the thickness and water absorption of multi-layer products (e.g. with a three-layer kitchen towel as the middle layer, with two-layer products as the bottom layer, with the side with the pillow facing inwards).

- Embodiment of a headbox area and a main drainage area of a tissue paper machine Embodiment of a headbox area and a main drainage area of a tissue paper machine
- Fig. Lb is a schematic representation of another
- Fig. Lc is a schematic representation of another
- 2a and 2b show an area of a texture screen with interconnected drainage zones
- 3a and 3b each show an area of a texture screen, in which the zones of blocked drainage are connected to one another.
- a sheet formation area of a paper machine is shown schematically in FIG.
- a material inlet nip 11 is formed by an inner dewatering and sheet forming screen 13 and an outer dewatering and sheet forming screen 14, which extend around various deflecting rollers 15 with different dimensions are and are guided around a portion of the circumference of the dewatering and forming roller 12.
- Leaf formation occurs between these two screens.
- the drainage and sheet formation screen 14 is a textured screen 16 provided with a texture and the inner drainage and sheet forming screen 13 is a texture screen provided with a texture 17 deposited.
- texture sieves among themselves preferably have different dimensions when they are guided over deflection rollers 18.
- the texture screens also have a different expansion compared to the respectively associated drainage and sheet forming screen and are guided over their own deflection rollers, as can be seen in FIG. This makes it possible to carry out a lifting, preferably a hydraulic lifting of the texture screen from the drainage and sheet forming screen, without major conversion measures. Most of the water passes through the dewatering and sheet forming screen 14 and the texture screen 16, so that such a lifting off would not be an advantage with the texture screen 16.
- FIG. 1b contains the same with the modified embodiment shown there
- a headbox 9 is provided, from which the material is deposited in the direction of arrow 10 on a horizontally oriented drainage and sheet forming screen 13 '.
- a texture screen 17 ' is underlaid over this drainage and sheet forming screen 13' over a certain distance.
- the texture sieve has drainage sieve zones 19 and sieve zones 20 of blocked drainage, these zones being able to form a very wide variety of patterns, depending on the need and intended use.
- the drainage zones 19 are connected to one another in a network.
- the zones 20 of blocked drainage are connected to one another in a network.
- Via the closed screen zones of the texture screens drainage through the sheet forming screen in the Z direction is prevented or severely restricted.
- the fibers are concentrated in the zones 19 of unimpeded drainage.
- the drainage and sheet forming screen should be as thin as possible so that there is little water transport in the X and Y directions.
- Texture screen in the area of the main drainage zone d. H. in the transition area from fiber suspension to fiber fleece with approx.> 10% consistency.
