Definitions
- tissue hygiene product e.g. B. kitchen towel, toilet paper, napkins, handkerchiefs, facial tissues and the like, either glue is used, or mechanical tools have been used to produce knurling or embossing, the layers in the area of the knurled seam or the embossing being extremely compressed and thus joined together. These methods are still commonly used today. The tools used for this, however, leave clearly visible imprints on the tissue surfaces. B.
- tissue paper in which at the same time an adhesion between the layers is produced by the embossing, as is the case in the case of edge embossing z. B. is common with handkerchiefs or napkins.
- the object (problem) of the invention is to provide a method and a device with which it is possible in a simpler manner, while largely maintaining the softness, strength and absorbency of the tissue paper, even with a larger number of layers to produce good layer adhesion between the layers of the tissue product produced with it, but without leaving clearly visible impressions on the outwardly facing tissue surfaces of the outer layers of the tissue product which the consumer perceives as negative.
- this object is achieved by the following method steps:
- the method and the device have the advantage that glue can be dispensed with in order to produce the layer adhesion and that the mechanical influence of the roller surface on the tissue surface is hardly or not visible.
- glue can be dispensed with in order to produce the layer adhesion and that the mechanical influence of the roller surface on the tissue surface is hardly or not visible.
- a visible, desired irregular pattern can be generated, which can be used to design new products.
- the paper is given a peach skin-like surface, which makes the paper feel very soft.
- roller pairs can work with different pressure, e.g. B. increasing pressure.
- the roller pairs can also be provided with different patterns. If the product has more than two layers, the layers can be passed through different roller pairs / nips.
- the invention also relates to the use of emery paper for producing layer adhesion between layers of tissue paper by pressing the surface structure of the emery paper into a tissue paper made up of at least two layers in the production of a multilayer tissue product intended for end use.
- each such “roughness tip” must have sufficient height, inherent strength and anchoring strength to penetrate deep enough into the paper can.
- the shape, hardness, intrinsic and anchoring strength of each "roughness tip” must be such that in the area of the end faces of the "roughness tips” acting on the fiber structure of the tissue paper, the highest possible surface pressure is created in a press nip under load, which is capable of to deform the fibers of a tissue paper which is exposed to this surface pressure in at least two layers one above the other in such a way that the surfaces of adjacent fibers come into such intimate contact with one another that punctiform intermediate fiber bonds occur, which in their entirety lead to the layers of the finished tissue product being arrested.
- a simple, not yet followed route to this is, for example, the use of abrasive grain materials made of, for example, aluminum oxide, silicon carbide or industrial diamond in a macro grain range P 40 to P 240 (DIN), anchored, for example, on suitable flexible abrasive pads or directly on the surface of a solid roller Metal or a suitable metal shell that can be mounted on a roller core.
- abrasive grain materials made of, for example, aluminum oxide, silicon carbide or industrial diamond in a macro grain range P 40 to P 240 (DIN), anchored, for example, on suitable flexible abrasive pads or directly on the surface of a solid roller Metal or a suitable metal shell that can be mounted on a roller core.
- training forms are conceivable that appear as a surface structure resembling emery paper on one or in the form of a ceramic shell, which can also be mounted on a roller core and withstand corresponding loads.
- Adequate solid rollers e.g. B. All-ceramic rollers
- the single figure shows, purely schematically, part of a machine for producing a two-layer tissue product.
- Single-ply tissue paper is first produced on a tissue paper machine and then brought together on a special processing machine to form a multi-ply product.
- two single-layer tissue papers 5 are fed to a pair of rollers 3, 4 via deflection rollers 1 and 2.
- the two webs run through a printing nip 6 provided between the printing rollers.
- a two-layer end product 7 runs out behind the printing nip 6.
- the layer adhesion is generated in the pressure gap 6.
- the rollers 3 and 4 are provided with a surface structure 8. This surface structure is like an emery paper with irregular roughness.
- the surface is preferably coated with an emery paper, an emery paper of the DIN Designation P 20 to P 240 comes into question, preferably as dry sandpaper.
- this surface structure can also be generated in some other way, such as. B. in connection with a ceramic roller (sintered grain) or by laser technology or laser engraving technology. It could be
- Sandblasting of the roller surface can be used. However, it should be comparable to that of an emery paper of the type mentioned. There would also be the possibility of having an endless emery paper in the form of a web run through the gap, which is why not all of it
- the pressure rollers 3 and 4 are normally designed as steel rollers.
- the surface structure preferably has this Steel rollers have an irregularity in the grain size, the grain distribution density and / or the grain shape, whereby pointed and also angular grains may be present.
- both printing rollers 3 and 4 are provided with this surface structure.
- absolute synchronization of the rollers is of particular importance. It is also possible to use a counter-roller with a screen structure on the surface.
- the rubber counter roller can be used with different hardness, for example 25 to 95 Shore A.
- the plastic sieves can be so-called simple to z. B. Four-shaft twill plastic sieves. Up to eight tissue layers can be combined to achieve satisfactory results. Preferably the
- tissue paper The residual moisture of the tissue paper is 3 to 10% and in particular 5 to 8%.
- raw tissue papers can be used. These are primarily made from natural fibers that come from wood. Both softwood (long fiber) and hardwood (short fiber) are used. The fibers are broken down by conventional chemical pulping processes, e.g. B. the sulfite or sulfate process, or mechanical, chemomechanical or chemothermomechanical digestion processes, such as. B. wood pulp, CTMP, HTCTMP. If necessary, chemical pulping processes, e.g. B. the sulfite or sulfate process, or mechanical, chemomechanical or chemothermomechanical digestion processes, such as. B. wood pulp, CTMP, HTCTMP. If necessary, chemical pulping processes, e.g. B. the sulfite or sulfate process, or mechanical, chemomechanical or chemothermomechanical digestion processes, such as. B. wood pulp, CTMP, HTCTMP. If necessary, chemical pulp
- Auxiliaries e.g. B. added to increase dry or wet strength and / or absorbency and / or to increase softness.
- the pulp can be used both as a pumping material and as a drying agent.
- the processing speed in the tissue paper machine is from 30 to 1000 m / minute, preferably 50 to 800 m / minute, more preferably 150 to 600 m / minute and in particular 300 to 500 m / minute.
- the method is suitable for raw tissue basis weights in the range between 12 and 40 g / m 2 , preferably between 13 and 25 g / m 2 , more preferably between 13.5 and 22 g / m 2 , in particular between 14 and 19 g / m 2 .
- a device of semi-technical size similar to that in the drawing was used, with two or more material webs being passed through the nip of two rollers that have a rough or roughened surface.
- the rough roller surfaces were produced by pasting the rollers with commercially available emery paper.
- Cotton was passed through a pair of rollers, the surfaces of both rollers being coated with P 100 grit.
- the pneumatic contact pressure was 4.0 to 5.0 bar, which corresponds to a line pressure between the rollers of 22 to 26 kN / m.
- Cotton wool was passed through a pair of rollers, the surfaces of the two steel rollers being coated with P 100 grit, and then through an embossing unit (steel / rubber embossing with a "gauze” embossing pattern).
- the pneumatic contact pressure was 4.0 to 5.0 bar, which corresponds to a line pressure between the rolls of 22 to 26 kN / m, and in the embossing press, the pneumatic contact pressure was 1.0 to 2.0 bar, which corresponds to a gap pressure of 6.5 to 10 kN / m.
- Thickness 10x 1.0 mm
- Softness 73 handfeel points
- Cotton was covered by a pair of rollers, the surface of one roller being coated with P 100 grit and the surface of the other roller being coated with a Kufferath Simplex 4-shaft twill polyester sieve monofilament 24.5 / 18 (contact pressure of both rollers approx. 4.0 to 5.0 bar, which corresponds to a line pressure between the rollers of 22 to 26 kN / m) and then by an embossing unit (steel / rubber embossing, contact pressure 1.0 to 2.0 bar, what corresponds to a gap pressure of 6.5 to 10 kN / m).
- Experiment 1 used. A very good layer adhesion was found in two layers, and a very good layer adhesion was also found in three layers. With four layers, the layer adhesion between the first and second and the third and fourth layers was very good, but only good between the second and third layers. Up to six layers, the layer adhesion decreased from the outside to the inside and was still present on the inside, but just sufficient. With eight layers there was no longer any layer adhesion between the innermost layers.
- roller diameters are suitable for the rollers for generating layer adhesion with applied emery cloth: 100 to 1000 mm, preferably 150 to 400 mm and particularly preferably 180 to 350 mm.
