Description

Technical Field

[0001] This invention relates to a method for manufacturing a fiber material web, particularly a method for manufacturing decorative paper, to a fiber material web, particularly a decorative paper, particularly a fiber material web obtainable according to the method, and to the application of the fiber material web as decorative paper. Background Technology

[0002] Specialized paper used for surface decoration of materials such as wood is generally called decorative paper. Known decorative papers are primarily produced from hardwood pulp. This type of paper can be used plain or printed with various designs. It can be used, for example, on furniture surfaces, flooring, and paneling.

[0003] Decorative paper is typically printed using gravure printing. In this method, printing ink is usually transferred from an engraving roller to the paper. Through the combination of paper color and different printing inks, there are virtually no limitations on the diversity of decorative designs. Printed designs cover a range from wood grain and stone textures to fantasy finishes.

[0004] Decorative paper can be manufactured in a variety of colors and areal densities. The surface is either satin / waxed or machine-varnished. Other important properties include high porosity, wet strength, lightfastness, and color stability.

[0005] To bond decorative paper to surfaces, such as wood materials, it can be impregnated with melamine resin, urea-formaldehyde resin, or acrylic resin, depending on the application. Due to its high absorption and penetration capacity, decorative paper can absorb twice its own weight in resin.

[0006] The preferred decorative paper is characterized by high wet strength, which ensures its smooth passage through the impregnation equipment.

[0007] To ensure optimal further processing during impregnation, suitable decorative paper possesses extremely high absorbency. Furthermore, to cover dark-colored carrier materials, such as particleboard or core paper, fillers can be incorporated into the decorative paper. Here, white and colored pigments with extremely high lightfastness and, as far as possible, chemical resistance are suitable.

[0008] Decorative paper is typically bonded to surfaces, especially wood-based panels, using pressing and laminating equipment. The impregnated resin is cured by localized high temperatures and pressures within the press, at which point the decorative paper bonds to the wood material. During lamination, this is usually achieved using hot melt adhesives. Structured pressing sheets can impart a near-realistic surface feel to the wood material.

[0009] The decorative paper described above can be manufactured by known methods. These methods typically include the following steps: first, generating a material stream, then sequentially supplying the secondary material stream to at least one headbox, at least one wire section for forming a web of fibrous material, at least one press section, at least one drying section with drying components, and then supplying it to a winding step.

[0010] Fiber webs, especially decorative papers, obtained using this method typically exhibit the characteristics listed below. Due to the high dry solids content after pressing, particularly when using a boot press, the paper is affected in that it exhibits less "adhesion" on the drying cylinders of the (first) pre-drying assembly in the drying section. Here, "adhesion" specifically refers to the humidified paper web adhering to the surface of the heated drying cylinders.

[0011] Cellulose fibers, typically used in papermaking, swell when they absorb moisture and shrink when they release water. As a result, the fibrous material web shrinks by about 1-5% in the drying section throughout the dewatering and drying process. This shrinkage is hindered by the aforementioned "adhesion."

[0012] Thus, when the fibrous material web is applied to a surface and / or comes into contact with printing inks and / or resins during printing, the paper may again change its dimensions and "elongate." This occurs to a degree similar to the shrinkage during drying. Because the paper web enters the drying section relatively dry when using a shoe press, the paper web adheres less to the drying cylinder and thus shrinks more strongly, which results in higher paper elongation during subsequent reprocessing.

[0013] This type of paper growth, also known as wet elongation, is only applicable to a limited extent, especially for decorative applications with strict dimensional requirements.

[0014] Therefore, the known methods for manufacturing decorative paper need to be improved. Summary of the Invention

[0015] This invention aims to meet this need.

[0016] In particular, a method should be provided for manufacturing high-quality fibrous material webs, characterized primarily by high porosity, wet strength, lightfastness, and color stability. The method should be as simple and economical as possible. Furthermore, the shrinkage of the paper during manufacturing should occur as predictably as possible, so that the subsequent "elongation" of the paper during printing and / or impregnation is as constant and reproducible as possible.

[0017] The objective is achieved by the method according to the invention, namely by a method for manufacturing fibrous material webs, especially decorative paper, the method comprising the following steps:

[0018] - Provides a flow of fiber materials.

[0019] - The fiber material stream is supplied in the following order to at least one fiber material box, at least one web section for forming the fiber material web, at least one press section, and at least one drying section with a drying assembly.

[0020] Its features are,

[0021] In the pressing section, the dry solids content of the fiber material web is set in the range of 45 wt% to 60 wt%, and after or during the drying section, the fiber material web is partially or completely humidified by means of an aqueous medium, wherein 2% to 30%, especially 4% to 20%, preferably 6% to 15% of the areal density of the fiber material web is applied to the fiber material web.

[0022] "Regarding the areal density of the fiber material web" refers to the areal density of the fiber material web manufactured according to the method, and not the areal density of the fiber material web at the humidified location.

[0023] That is to say, for the areal density of 100 g / m² manufactured according to the method of the present invention 2 The fiber material width will be a total of 2g / m 2 Up to 30 g / m 2 Water is applied (humidified) onto the fiber material web.

[0024] The feature “partial or complete humidification by means of an aqueous medium” means that the fiber web is humidified transversely or longitudinally in a predetermined area (partially) or over the entire width, so that, in particular, by two measures, namely targeted strong drying and targeted rehumidification of the fiber web, the Mütek wet elongation of the fiber web can be set to be 2.0% to 4.0% transversely to the machine running direction and 0.5% to 1.5% longitudinally along the machine running direction, and this is preferably carried out at a high speed of up to 1100 m / min for the fiber web.

[0025] In conventional pressing processes, the dry solids content is preferably adjusted in the range of 46 wt% to 53 wt%, while in shoe presses it is preferably adjusted in the range of 52 wt% to 58 wt%.

[0026] Next, if necessary, the fiber material can be flattened first and then supplied to the rolls for easier storage and / or easier transport.

[0027] The fiber material manufactured in this way is especially a type of decorative paper.

[0028] In this article, the expression "including" may also mean "consisting of".

[0029] All specifications and standards mentioned herein and in the examples refer to those in force as of the priority date. If no priority is claimed, the specifications and standards mentioned herein and in the examples refer to those in force as of the application date.

[0030] The method according to the invention is characterized in particular by regenerating the aforementioned "adhesion" by applying water / humidity after or during the drying section, which reduces subsequent elongation when in contact with liquids, such as during printing or immersion.

[0031] Furthermore, the method remains relatively simple, and its high speed allows for economical implementation. Additionally, the resulting fiber material exhibits superior porosity, wet strength, lightfastness, and color stability.

[0032] In the method of the present invention, a fiber material stream is first provided. This fiber material stream is preferably characterized in that it comprises cellulose fibers (pulp fibers) of hardwood / broadleaf or softwood / coniferous wood, or a mixture thereof, or is composed of said cellulose fibers or a mixture thereof, wherein the fiber length of said cellulose fibers is preferably from 0.6 mm to 3 mm, particularly in the range of 0.8 mm to 2 mm. Furthermore, the fiber material stream may contain various fillers, such as titanium dioxide, kaolin, etc., and / or pigments and / or other additives and / or various functional chemicals, such as wet strengthening agents, etc., and / or production aids, such as retention agents and defoamers. Here, the material consistency commonly found in the headbox is typically from 0.5 wt% to 2 wt%, particularly from 0.8 wt% to 1.5 wt%.

[0033] In the method of the present invention, the fiber material stream is then introduced into at least one headbox and at least one screening section for forming the fiber material web.

[0034] A headbox is typically a nozzle through which fibrous material is applied uniformly in quantity and concentration across the width of a circulating filter screen, through which solids are separated from moisture. During the dewatering process, a uniform fiber mat is formed on the filter screen, which forms the basis of the subsequent paper. At the end of the wire section, the solids content is preferably 15 wt% to 25 wt%, particularly in the range of 18 wt% to 22 wt%.

[0035] In the method of the present invention, the fibrous material is then introduced into at least one pressing section.

[0036] In the pressing section, it is preferable to further dehydrate the fiber mat that can be produced in the web section. For this purpose, the fiber mat is usually pressed with the assistance of felt. This can be done, for example, between two rollers that press against each other. Here, the felt used has the function of conveying the web through the pressing section without damage and absorbing the water squeezed out in the pressing gap.

[0037] In the method of the present invention, the pressed fiber material is then guided to at least one drying section having a drying component.

[0038] The drying section typically consists mainly of steam-heated drying cylinders that come into contact with the paper web to heat it to a degree that evaporates the water still present in the paper web until the desired final humidity is achieved. These preceding and following drying cylinders preferably form a so-called drying assembly. The drying assembly can be loaded with steam differently to allow for control of the drying process.

[0039] In the method of the present invention, the dry solids content of the fiber material web is set in the range of about 45 wt% to 60 wt% in the pressing section.

[0040] From an energy perspective, it is generally desirable to obtain the highest possible dry solids content. However, there are limitations from a technical standpoint. In conventional roller / press mills, depending on the specific material input, a dry solids content of 46 wt% to 53 wt% can be achieved.

[0041] When using one or more shoe presses, dry solids contents of up to 60 wt% can be achieved, particularly in the range of 52 wt% to 58 wt%. Excessive pressure can damage the paper web, while insufficient dry solids content can lead to operational problems or higher steam consumption in subsequent drying sections, resulting in higher drying costs.

[0042] According to the method of the present invention, the fiber material web is humidified in the drying section. Here, the humidification rate is 0.8 g / m². 2 Up to 45g / m 2 or 1 ml / m 2 Up to 30 ml / m 2 The amount of water applied is preferred. A preferred range particularly includes: 1 ml / m³. 2 Up to 15 ml / m 2 2 ml / m 2 Up to 15 ml / m 2 1 ml / m 2 Up to 10 ml / m 2 or 2 ml / m 2 Up to 6 ml / m 2 .

[0043] Thus, the amount of water to be applied relative to the areal density of the fiber material web, and consequently the water content of the medium, can be set in the range of 2% to 30%, particularly in the range of 4% to 20%, and preferably in the range of 6% to 15%.

[0044] Furthermore, a preferred feature of the method according to the invention is that the pressing section includes a positive press, particularly a boot press.

[0045] After the fiber web is formed in the web section, it must be further dehydrated. This is typically done by applying mechanical pressure perpendicular to the surface of the fiber web to increase the dry solids content. This is carried out in the so-called press section. Here, the fiber web is typically processed between rollers at a specific pressure. The water pressed out of the fiber web is periodically absorbed by felt applied to the respective rollers.

[0046] Therefore, it is preferable to use a press with a traditional roller-roller or shoe-roller design.

[0047] Shoe presses are known in papermaking and typically include a shoe that presses against a rotating corresponding roll. Here, a flexible plastic shell can float on the shoe with the aid of an oil film. The rotating corresponding roll is usually covered with felt to drain the pressed water.

[0048] When pressing the fiber web, a dry solids content of 45 wt% to 60 wt% can be achieved. After pressing, residual moisture in the fiber web must be further removed. This is typically achieved through evaporation and / or vacuum action. The most common method here is contact drying on a steam-heated drum. Here, heat energy is transferred from the outer wall of the drying cylinder to the surface of the fiber web through direct contact. The drying section consists of multiple drying cylinders, which typically guide the fiber web alternately through the upper and lower sides.

[0049] For this purpose, both single-row and traditional double-row drying units can be used.

[0050] Furthermore, a preferred feature of the method according to the invention is that humidification with an aqueous medium is carried out via nozzle humidification, particularly via spraying a water-air mixture, especially via a two-component nozzle.

[0051] In practical implementations, a nozzle humidifier with a two-component nozzle and / or a pneumatic atomizing nozzle is used as the non-contact application device. The throughput of the water-air mixture is preferably segmented and / or adjustable in the direction of travel of the fiber material and / or in the transverse direction. Preferably, each nozzle is individually adjustable and / or set. For good atomization, the water temperature is suitably between 20°C and 95°C, preferably between 40°C and 90°C.

[0052] The aqueous medium is preferably free of pigments, so that the color of the fiber material will not change.

[0053] Furthermore, a preferred feature of the method according to the invention is that the humidification can be adjusted laterally to the width of the fiber material.

[0054] This has the advantage that the width of the attachment can be controlled.

[0055] According to the present invention, the fiber material is rehumidified after or during the drying process.

[0056] Furthermore, a preferred feature of the method according to the invention is that humidification is performed at the starting point of the first drying component.

[0057] Preferably, the humidification is performed when the paper web moisture content is between 30 wt% and 50 wt%, more preferably between 42 and 52 wt%. Humidification is preferably performed on a vacuum roller.

[0058] Furthermore, the method according to the invention is preferably characterized in that the humidification is carried out in the range of 50 wt% to 70%, preferably 48 wt% to 68 wt%, of the dry solids content of the paper web.

[0059] Furthermore, the method according to the invention is preferably characterized by guiding the fiber material at a speed between 500 m / min and 1100 m / min, particularly in the range of 700 m / min to 900 m / min.

[0060] In particular, the use of a boot press allows for high-speed fabrication of fiber materials.

[0061] The method according to the invention results in a fiber orientation that is preferably longitudinal rather than transverse, influencing elongation. Preferably, this fiber orientation can be adjusted via a V-shaped jet through a headbox. A V-shaped jet refers to the velocity difference between the material ejected from the headbox and the filter screen velocity.

[0062] Here, the preferred ratio of the longitudinal to the transverse fiber orientation is 1.0 to 2.2, and more preferably 1.2 to 2.0.

[0063] Furthermore, the method according to the invention is preferably characterized in that the headbox is achieved by a V-shaped jetting within the range of +50 m / min to -50 m / min, preferably within the range of +40 m / min to -40 m / min.

[0064] Furthermore, the method according to the invention is preferably characterized in that the paper web has a breaking force ratio of 1.0 to 2.2, preferably 1.2 to 2.0 (ISO 1924-2).

[0065] Furthermore, the method according to the invention is preferably characterized in that the fibrous material stream mainly comprises the following types of cellulose: long-fiber cellulose, such as spruce and pine, and short-fiber cellulose, such as birch, beech, poplar, oak, eucalyptus, or mixtures thereof. In particular, eucalyptus cellulose or mixtures thereof from Eucalyptus grandis, Eucalyptus stenoptera, and Eucalyptus globulus are used.

[0066] Furthermore, a preferred feature of the method according to the invention is that the fibrous material is milled to a Schopper grind of 16° to 40°. This can be done with fillers or with cellulose only. The advantage of milling only pure cellulose is that the lifespan of the milling equipment is significantly longer.

[0067] Furthermore, the method according to the invention is preferably characterized in that the fibrous material stream includes cellulose, in particular, certified according to FSC and PFSC.

[0068] The present invention also relates to a fiber material web manufactured according to the method described above.

[0069] The present invention also relates to a decorative paper manufactured according to the method described above.

[0070] The preferred embodiments of the method according to the invention described above are similarly applicable to fibrous material webs or decorative paper obtained by the method.

[0071] The present invention also relates to a preferred fiber material web that can be obtained by the method according to the invention, particularly a decorative paper, said fiber material web having at least one of the following characteristics.

[0072] - Wet elongation according to Mütek, which is 2.0% to 4.0% transversely to the machine running direction, especially 2.2% to 3.3% and 0.5% to 1.5% along the machine running direction, especially 0.7% to 1.3%.

[0073] Here, the wet elongation is determined using a Mütek WSD02 (Emtec) measuring instrument based on Mütek's wet elongation rate. Measurement parameters include a lateral tensile force of 4 N / 60 mm and a longitudinal tensile force of 1 N / 60 mm after water is applied to one side for 25 seconds. The measurement results are obtained by averaging along the lateral direction at measurement positions 10 cm from the edge, the center, the outer edge, and the center-to-center measurement.

[0074] Here, the wet elongation is calculated based on Mütek's formula as follows:

[0075] Transverse Mütek wet elongation = (((FS + TS) / 2)) + center - center + TS) / 3.

[0076] The longitudinal Mütek wet elongation is derived from the “center-to-center” position.

[0077] Here, FS, TS, and center-center represent the operator side and drive side, and center-center is the position between the amplitude center and FS.

[0078] - The actual elongation due to impregnation is 0.8% to 1.8%, especially 0.9% to 1.7%, in the transverse direction of machine running and 0.2% to 1.2%, especially 0.3% to 1%, along the direction of machine running.

[0079] - Preferably 40g / m 2 Up to 150 g / m 2 Especially for 45 g / m 2 Up to 90 g / m 2 The areal density (ISO 536).

[0080] - Gurley porosity from 10 s to 28 s, especially from 14 s to 26 s (ISO 5636-5).

[0081] - 15 wt% to 42 wt%, especially 20 wt% to 38 wt% of filler content (ISO 2144).

[0082] - Buick smoothness (ISO5627) on trim surfaces, ranging from 80 s to 220 s, especially from 140 s to 210 s.

[0083] - The longitudinal / transverse ratio of fracture force MD / fracture force CD from 1.0 to 2.2, especially from 1.2 to 2.0 (ISO 1924-2).

[0084] - Preferably a width of 300 cm or 227 cm.

[0085] Therefore, all the properties described above are explicitly disclosed separately, and all possible combinations of the properties described above are also disclosed.

[0086] The preferred embodiments of the method described above according to the invention are similarly applicable to the fiber material web or decorative paper itself, and especially to the fiber material web or decorative paper obtained by the method according to the invention.

[0087] The fiber material web, especially decorative paper, according to the invention is preferably characterized in that the fiber material web exists in shades of white, cream, beige, brown, gray, and / or black.

[0088] The present invention also relates to the application of the fiber material web as decorative paper, particularly the use of the fiber material web as decorative paper, especially for interior decoration and / or furniture industry decorative paper, preferably for surface treatment of wood materials, such as coated boards, tables, floors, kitchen countertops, windowsills, and / or for outdoor applications, such as decorative paper for building facades.

[0089] The preferred embodiments of the method according to the invention described above are similarly applicable to applications according to the invention. Attached Figure Description

[0090] Figure 1 A schematic diagram shows a possible apparatus suitable for implementing the method according to the invention or suitable for manufacturing fiber material webs according to the invention. Detailed Implementation

[0091] This diagram illustrates the rotary guidance of the fiber web via a drying cylinder and vacuum rollers. This rotary guidance is particularly advantageous because the nozzle humidifier can be positioned in the lower region of the vacuum rollers, especially between the "3 and 9 o'clock positions." This allows excess water to easily drip downwards without contacting the fiber web.

[0092] Alternatively, the nozzle humidifier can be positioned on vacuum roller 1 or 3. For this purpose, a single-row drying section is particularly suitable because it has free access to the paper web, and the nozzle humidifier can draw in the water-gas mixture by means of the vacuum roller penetrating into the paper web.

[0093] The invention will now be described in detail with reference to non-limiting examples.

[0094] In order to manufacture a fiber material web having an actual elongation of 1.1% in the transverse direction and 0.45% in the longitudinal direction in the impregnation channel, which is used as decorative paper according to the present invention, the following setting parameters are selected.

[0095] Eucalyptus cellulose is used, which has a grind size of 21°SR and a filler content of 32.5 wt% consisting of titanium dioxide, a V-shaped jet speed of -18 m / min, and a shaking index of 2900 [1000 / min] at a machine speed of 850 m / min and a line load of 850 KN / m on the boot press. Here, the water flow rate of the nozzle humidifier is set to 360 l / h. The fiber material web used as decorative paper is manufactured as follows:

[0096] - Provides fiber slurry flow,

[0097] - The fiber material flow is supplied to the fiber material box, the web section for forming the fiber material web, the pressing section, and the drying section with drying components in the following order.

[0098] In the pressing section (shoe press), the dry solids content of the fiber web is adjusted to 55 wt%. The fiber web is then humidified again in the drying section, with the areal density of the fiber web (72 g / m²) adjusted accordingly. 2 Apply 4.75% water to the fiber material web.

[0099] These settings produce a product with an areal density of 72 g / m². 2 The fiber material web, used as decorative paper for finished paper rolls with a width of 206 cm, has an elongation of 2.25% transversely and 0.65% longitudinally according to Mütek (as described above) at a Gurley porosity of 14 s (ISO 5636-5). The breaking strength ratio (ISO 1924-2) is 1.25. After further conventional impregnation of the decorative paper, the fiber material web exhibits excellent very low actual elongation, which is consistently in the range of 0.8% to 1.8% transversely in the machine running direction and consistently in the range of 0.2% to 1.2% longitudinally in the machine running direction.
