Definitions

  • the invention relates to a method for producing a material web, on at least one side of a support a plastic layer made of a mixture of plastic material and particle-like soluble particles is generated and connected to the carrier, wherein the soluble particles can be removed by such a solvent are resistant to which the plastic material and that thereafter the soluble particles are at least partially from the plastic layer with the formation of through-channels be detached.
  • a material web of the type mentioned above for use in a paper machine is described in EP-B- ⁇ 196 ⁇ 45.
  • As a carrier it has a liquid-permeable fabric which is a 1.3 to 5 mm thick layer of an elastomeric polymer resin is applied.
  • the plastic layer has through channels on that of the otherwise smooth and level Go outside to the carrier and in the paper machine serve as drainage channels.
  • the through channels are manufactured in such a way that textile fibers are homogeneously dispersed in the polymer resin, before the mixture of textile fibers and polymer resin on is applied to the carrier.
  • a Non-woven fabric applied to the carrier and then the coating be made with the polymer resin.
  • the textile fibers consist of an organic material that is dissolvable by using a solvent, the Plastic layer resistant to this solvent is.
  • the textile fibers are removed after application the polymer resin by applying the solvent, so that channels arise, the shape and the course correspond to the detached textile fibers.
  • Textile fibers instead of Textile fibers suggested particulate particles that are homogeneous be distributed in the polymer resin. As material for this Particles become inorganic salts or their hydrates or oxides suggested. They can be made using appropriate solvents in the same way as the textile fibers made of the polymer resin are removed and leave pore cavities.
  • the soluble components - are there are fibers or particle-like particles - in the polymer resin distribute evenly and this distribution when applying maintain the mix.
  • the mixture it comes from polymer resin and soluble components to segregation, so that it is not guaranteed that by the detachment of the particles through passageways arise. Out for this reason, no different distributions can be made produce the soluble components across the cross-section.
  • polymer resins tend to harden after curing to form a closed surface that is detaching of the soluble textile fibers contained in the polymer resin or particles.
  • the surface of the plastic layer to grind so that a connection to the soluble Fibers produced and also creates a smooth surface becomes.
  • a grinding process is very time consuming.
  • it must be in an appropriate excess Plastic material can be applied and during the grinding process dust accumulates, which is vacuumed and either disposed of or returned must be processed.
  • a smooth surface arises, which detaches the paper web from the paper machine belt with special needs. Paper webs tend to suck yourself on smooth surfaces.
  • paper machine belts are used This type has a number of advantages over known felts attributed according to the batt-on-base principle, namely enlarged Resistance to permanent deformation and therefore longer Operating times and consequently lower set-up costs, improved abrasion resistance and higher structural strength, lower Affinity for contaminating substances as well as more uniform Pressure distribution and thus improved drainage.
  • the soluble components can fuse together.
  • a conceptually different path is in accordance with the proposal EP-B- ⁇ 187 967.
  • a porous plastic layer on a carrier produces loose particles of a synthetic polymer resin on the order of ⁇ , 15 to 5 mm on the surface a base fabric and then a heat treatment undergo, in which the polymer resin particles over the softening point be heated so that it turns on their contact points with each other and with the carrier fabric merge.
  • a resinous binder is provided his.
  • loose fibers can also be found be distributed to the carrier tissue. After the particles have adhered or fibers remain with each other and on the carrier fabric Clearances that allow the plastic layer to flow through do.
  • the material web initially consists exclusively of polymer particles is produced by exposure to heat from their Contact points are interconnected. If necessary can be a reinforcement structure like a reinforcement be completely stored in the tape thus formed. Here it can be a pure fiber product or a fabric act.
  • the particles can also have different diameters have one increasing from one side to the other To create permeability.
  • a polymer coating is made using a peel-off film under simultaneous exposure to heat and pressure is applied to a support, whereby the polymer film due to the heat on the peel-off film Forms drops with the formation of free spaces the consequence that the plastic layer applied to the carrier is porous.
  • this method too, it is difficult adjust the permeability of the plastic layer reproducibly and adapt to the respective requirements.
  • foils are not available in the width required here Available and would not be with sufficient uniformity producible.
  • the invention has for its object a method for To provide production of a material web of the type mentioned at the outset, with which a desired distribution of the soluble Can achieve particles within the plastic layer. Another task is to design the process so that the soluble particles are made out in a simple manner remove the plastic layer.
  • This object is achieved in that as Plastic material a plastic powder is provided that mixes with the soluble particles and onto the carrier is applied, and that by heat and pressure treatment the mixture of plastic powder and soluble particles Plastic layer with the soluble particles inside is generated before the soluble particles at least partially be detached from the plastic layer.
  • the grain size of the particles of the plastic powder and also the the soluble particles and their mixing ratio can each can be set within wide limits as required so that a desired structure of the plastic layer results, especially what the after removing the soluble particles resulting cavities of the through channels.
  • the soluble particles should have an average diameter from 3 ⁇ to 5 ⁇ um.
  • the average grain size of the Plastic powder should be less than that of soluble Particles, expediently only half to a third of the of the soluble particles and in no case more than Be 1 ⁇ ⁇ m. In this way the soluble particles of a plurality or even a plurality of particles of the plastic powder practically encased, and it creates a relatively dense Pakkung.
  • the volume ratio between plastic powder and soluble Particles should expediently be set so that that the soluble particles are not just in the cross-plane direction the plastic layer, but also in the plane of the plastic layer are at least partially in line with each other open pores in the plane of the plastic layer and thus drainage volume provided and thus the water absorption capacity is improved.
  • the volume ratio between plastic powder and soluble Particles are expediently in the range between 1/4: 3/4 and 1/2: 1/2, preferably in the range 2/3: 1/3.
  • the plastic powder and the soluble particles can also applied in layers, with different layers Grain sizes, materials and mixing ratios can be provided to account for the respective requirements to wear. So the soluble particles can become the carrier towards larger layers or continuously. Alternatively or in combination, the number of soluble Increase particles towards the carrier from layer to layer. Both Measures serve to ensure permeability towards the wearer to get bigger, like this especially when using it the material web in the forming and press area of a paper machine is desired.
  • the soluble particles are removable by such a solvent which the plastic material is stable, and that after that these soluble particles are removed.
  • Roughness-enhancing impressions produce what in particular when using the material web as a paper machine belt from Advantage is. This is because the inclination of the paper web, sticking to the paper machine belt too much, counteracted without causing markings.
  • the paper web detaches from the paper machine belt much more easily than the same with known designs Genus as known from EP-B- ⁇ 196 ⁇ 45 and EP-B- ⁇ 273 613 are.
  • the impressions have through their distribution in relation to the openings of the through channels small size so that there is enough contact area with the paper web, for even support and pressure transfer to enable.
  • the passageways and the embossments have also the consequence that the rewetting of the paper web is low.
  • Another advantage of this procedure is that by indenting the soluble particles where the soluble particles Particles are present on the outside near the surface, a connection to these is established. After detaching The solvent has access to the soluble particles soluble soluble initially enclosed in the plastic layer Particles and can therefore also completely dissolve them remove. The impressions then form the openings of the through channels. The procedure thus replaces the Grinding treatment according to EP-B- ⁇ 273 613.
  • the soluble particles should preferably be at a temperature the plastic layer can be pressed into this the plastic layer compared to the condition at room temperature is softened. This can be done in that the soluble Particles following the creation of the plastic layer applied and pressed in at an even higher temperature.
  • the pressing can be done by a calender treatment become.
  • the soluble particles Preferably have an average diameter of 5 to 1 ⁇ ⁇ m.
  • both should be made of the same material so that the removal can be done in one operation using the same solvent.
  • those substances should be selected which remain essentially dimensionally stable under the heat effect of the production of the plastic layer.
  • polymeric particles come into question which have a higher heat resistance than that of the plastic matrix in which the soluble particles are embedded. These conditions should expediently also apply to the soluble particles pressed into the outside of the plastic layer.
  • soluble particles or particles are not adversely affected by the heat treatment necessary for the formation of the plastic layer and are easy to pour and therefore scatterable.
  • Organic substances e.g. B. carbohydrates (sugar), or salts of organic acids, such as citric acid, ascirbic acid etc.
  • An additional antioxidant should be added to the plastic powder.
  • soluble particles of at least two substances are used, each one of the substances by a solvent is removable, against which the other substance (s) is or are stable.
  • This idea is basically that EP-A- ⁇ 3 ⁇ 3 798 and EP-A- ⁇ 32 ⁇ 559 in which the use of soluble fibers within a felt is suggested has been. It is understood that these soluble particles compared to the conditions of use for which the material web is intended is, must be constant, d. H. in case of use as a paper machine belt compared to those coming from the paper web Liquids or vapors. Alternatively, can be provided be that the soluble particles are only delayed and let it gradually separate from the matrix.
  • a second plastic layer with through channels created in the same way as on one side becomes.
  • the number and / or size of the soluble Particles in the second plastic layer directed away from the carrier increase, and it should be the number and / or size of soluble Particles in the areas adjacent to the carrier of both Plastic layer must be the same size. It is understood that other distributions are possible if this is for the intended Use is more appropriate. Of course you can the outside of the second plastic layer also in in the manner already described with impressions be generated by pressing in soluble particles.
  • the carrier of the material web according to the invention has the task the material web essentially only has dimensional and structural strength to give and if necessary absorb longitudinal and transverse forces.
  • the carrier can have one or more layers of strength be constructed. In the case of a base fabric, everyone comes Tissue types in question, especially those from the area the paper machine tapes are known.
