Decorative textile laminate board and method for producing it

The invention concerns laminated material decorated tiles and in particular such, with which the laminated material is a laminate from textilen materials, which likewise exhibits a surface decoration layer from textilem material. Multilevel textile materials, as they are descriptive for example in the US-PS Nr.3, 307.990, became already the production of laminates provided with textilen layers to use, which found to the inner lining of automobiles use. The textilen layers on the laminated material were connected by a span an adhesive it or glue. These well-known laminated material plates could satisfy for different reasons not completely, which are connected with their structural stability and in particular with their firmness in relation to layer replacements. There was the task to create laminated material plates which admitted contrary to that so far of Schiehtstoffplatten a high structural stability and a high firmness in relation to layer replacement exhibit. Additionally these plates should a high measure of impact strength exhibit, however be nevertheless flexible. Further the new laminated material plates an appearance pleasant from the aesthetic point of view on are to exhibit. Further they are to be economically producible, so that they are extremely interesting from the commercial point of view on. Besides the use of glues or adhesives is to be avoided with the production of the new plates, with which with the use of glues or adhesives connected solvents and the problems arising thereby are also omitted. Thus new laminated material decorated tiles are to be created, which exhibit few evaporatable portions relative to the difference from well-known laminated material plates from polymer resins, so that hardly gases develop, which can condense in the proximity of the attachment place of the plates, for example in an automobile, and settle on surfaces. This feature was observed when using different Sehichtstoffplatten from polymer resins as automobile interior equipment components in the last years and represents a substantial disadvantage of these well-known laminated material decorated tiles. The goals stated above are achieved with the new laminated material decorated tiles in accordance with the invention, as well as all disadvantages connected with that well-known laminated material decorated tiles avoided. The textile laminated material decorated tile according to invention consists of a core of ungewebten synthetic textile fibers, an interior situation of warm-merged, thermoplastic, schmelzgesponnenen, synthetic textile fibers in arbitrary form, a second interior situation, which a thermoplastic plastic foil or one the first interior situation appropriate fiber layer enclosure, whereby in each case the first and second interior situation resting against a surface of the nuclear situation sand yield-like and are connected the three layers include the core by needles, from a back layer consisting of plastic foil or a felt layer of ungewebten textile fibers, which is connected by needles also excluding the second interior situation, and from a textilen decoration layer, which is connected with the exterior surface of the first interior situation thereby that the melted fibers first Interior situation in the fund of the textile material of the decoration layer are embodied. The laminated material decorated tiles according to invention can find in particular as inside paneling for automobiles, boats, entertainment vehicles u.dgl. use, as well as completely generally as Ausbzw. Verkleidungsplatten, whereby the application of the laminated material decorated tiles according to invention lies in the knowledge range of the specialist. The invention concerns a far procedure for the production of the Sehichtstoff decorated tile. This procedure is characterized by that on a continuously moved on first layer of schmelzgesponnener fibers a unverfestigte second layer of synthetic textile fibers is applied, as well as applied on this unverfestigte layer again a third layer from a foil or from schmelzgesponnenen fibers that afterwards this multilevel course under formation of a laminated material is ennobled that afterwards a back layer made of foil or a felt layer from ungewobenen textile fibers is applied and ennobled with the third layer that afterwards the multilevel course is turned and led by a furnace, whereby the course up to the softening point of the materials in the layers is warmed up that on the outside surface of the first layer a decoration layer is presented, and that finally the layers in a form under pressure and heat with the decoration layer to be connected and the laminate one solidifies. The invention is more near described in the following on the basis a remark example of a plate according to invention as well as a device to its production with reference to the designs, in those Fig.! the pulled apart opinion of a laminated material decorated tile according to invention is, in which the individual layers are separately represented, Fig.2 a cross section by the finished plate after Fig.1, Fig.3 an increased side view of the surface layers from plate after Fig.2, Fig.4 a spatial opinion of a laminated material decorated tile according to invention in form of a door interior plate for an automobile, Fig.5 a schematisehes diagram of a production road for the production of laminated material decorated tiles according to invention as well as Fig.6 a side view a part of the production road after Fig.5 form-presses is. In Fig.1 one recognizes a spatial opinion of an execution form of a laminated material decorated tile according to invention, whereby the different layers of this laminate are pulled apart represented. The laminated material decorated tile --10-- an outside textile material layer points --12-- up, the one decoration surface forms and to a neighbouring layer --16-- from thermoplastic textile fibers is melted on. The external layer --14-- if a foil from synthetic resin can be, a soft, laminar textile layer is however preferably, those to the layer --20-- is melted on. The layer --20-- can if a plastic a olle be, is however preferably alike as the layer --16-- trained. Between these layers is a core --18-- from ungewobenen textile fibers sand yield-like enclosed. The layers --12, 14, 16, 18 and 20-- by injecting under warmth is laminated and solidified, whereby integrals laminate structure of high firmness develops, which exhibits further high Delaminationsfestigkeit as well as is aesthetically responding. With reference to Fig.5 in the connection one shows, like the layers --12, 14, 16, 18 and 20-- built up and with one another under education of the solidified laminated material - decorated tile --10-- is combined, whereby Fig.5 a schematic descripton of a system for the execution of an execution form of the procedure according to invention for the production of the laminated material decorated tile --10-- is. As initial step becomes with this execution form of the procedure according to invention on a conveyor --3--, that by drive wheels --4, 5-- , a layer is propelled --16-- from thermoplastic, warm-fusible artificial fibers in the form of more gewobener or mesh commodity, or in not gewobenem condition applied. Examples of such fibers are polyolefin pile fibers from PL or polypropylene. Thus for example the layer exists --16-- from a situation of gewobenen pile fibers from polypropylene. Preferably the layer has --16-- a weight from approximately 200 to approximately 700 g/m2 and a thickness from approximately 3 to approximately 12 mm. The layer --16-- becomes under a coating station --7-- led past, where on its upper even surface an even distribution of draw, synthetic resin textile fibers unverfestigten --18-- taken place. Preferably are the synthetic resin fibers --18-- Waste fibers from cut up textile materials. The waste material --18-- from artificial fibers becomes from a shredder --9-- (Schredder), in which waste textiles in textile fiber components --18-- to be broken open and cut up, over a line --8-- the coating station --7-- supplied. When carrying on with the matured fibers --18-- loaded layer --16-- on the conveyor --3-- becomes a second layer --20-- from gewobenen or ungewobenen thermoplastic sehmelzbaren artificial fibers --20-- above the fibers --18-- applied, around these as core between the layers --16 and 20-- to include sand yield-like. The layer --20-- can with the layer --16-- just as trained its or alternatively a foil from a fusible thermoplastic synthetic resin as from PL or polypropylene its. Such foils are preferably inserted with a thickness from approximately 0.0125 to approximately 0.382 mm. From the layers --16, 18 and 20-- existing sand-yield-like structure becomes from the conveyor --3-- resumed and passes a Nadelstuhl --11--, where the situations --16, 18 and 20-- to be solidified and interconnected. The needle techniques for connecting textile layers are well-known, e.g. from the US-PS Nr.2, 059.132, Nr.2, 910.763 and Nr.3, 684.284, and thus not in the detail are described. Preferably single-step is ennobled, whereby needle sizes --32-- with several blows (beards) to be used, which are arranged by between 18 and 74 Nadeln/cm in a density. That after that needles received, from the layers --16, 18 and 20-- received laminate becomes then at its upper surface, i.e. at the exterior surface of the layer --20--, with a felt-laminated --14-- provide from ungewobenen textilen pile fibers. Preferably this felt edition has --14-- a weight per unit area from approximately 200 to approximately 700 g/m2 and a thickness from approximately 3 to approximately 12 mm. Then at its surface the felt edition becomes --14-- exhibiting layer laminate from the layers --16, 18 and 20-- a further ennobling subjected, whereby a two-stage ennobling on the Nadelstuhl --17-- taken place and the felt edition --14-- with the layer --20-- one connects. It is important that with this needle step only the felt edition --14-- and the layer --20-- to be ennobled with one another, in order to receive the indulgence of the received product. Then the received multilevel course becomes --19-- turned and by a furnace --21-- so led that the felt edition down is, whereby the temperature of the course --19-- up to the softening point of the synthetic, fusible fibers or - foils in the layers --16 and 20--, or scarcely over it, one increases. Directly after the heat treated compound course --19-- from the furnace --21-- withdraws, becomes on the surface of the layer --16-- a decor cloth --12-- applied. Each decor cloth, however a gewobene or a mesh commodity can be applied is preferably used. For example gewobene, including-like are applied in accordance with product the US-PS in accordance with Nr.3, 187.782 or Florware the US-PS Nr.2, 110.866. Preferably the applied material has layer --12-- a weight per unit area from 150 to 800 g/m2. The compound course covered with the decor cloth --19-- becomes immediately after it, while it still on a increased temperature is, into a laminating press --23-- brought in, in that the compound course --19-- at the same time into a form pressed and the received molded article in form of a plate --10-- one cuts out. In Fig.2 one recognizes the arrangement of the situations --12, 14, 16, 18 and 20-- before their laminating in the press --23--. In the layers --14, 18 and 20-- drawn in structures in form 'reverse funnel show the fibrous structure in the layers solidified by ennobling and suggest that the individual layers are connected in their structure among themselves. From Fig.2 one recognizes that specific layers are connected by needles, but not all situations. Due to this mode of production different favourable characteristics result in in such a way manufactured laminated plates in accordance with the invention. In Fig.6, in the one side view of the press --23-- , recognizes one is explained the press in the opened condition, after the compound course --19-- injected and from the course the laminated plate --30-- cut out was. The lower, firm pressure plate --24-- can on the fusing temperature of the resin of the fibers in layer --20-- are heated. The upper, mobile Preßplatte --25-- can in the same way on the fusing temperature of the fibers in layer, gesponnenen from the melt --16-- are heated. At the edge is the Preßplatte --25-- with gumption organs --26-- provided, around the plate --30-- to cut out in their desired form. Under the pressure in the press --23-- a further solidification of the interconnected layers finds --14, 16, 18 and 20-- instead of, whereby the laminated material plate --30-- one forms and whereby the fund of the Webstoffes --12-- into the substance of the layer --16-- one in-presses. The heat-melted fibers in the layer become --16-- upward into the textile surface layer --12-- hineingedrüekt, so that the fund of the surface layer --12-- in the layer --16-- by the melted fibers of the layer --16-- one embodies. In the press --23-- to the solidification of the layers --12, 14, 16, 18 and 20-- expenditure-practiced pressure preferably lies within the range of approximately 34 to approximately 2800 kPa. In this way a good combination of the layers becomes --12, 16 and 18-- reached. In Fig.3 is an increased side view of the solidified layers --12, 16 and 18-- after laminating in the press --23-- represented. In particular one recognizes that a Webstoff --12--, that from a fund fabric --24-- and Florfasern --26-- exists, into the layer --16-- one in-pressed. Melted one and afterwards cooled down fusion fibers --28-- from the layer --16-- became thereby under heat and pressure into the layer --12-- pressed in, whereby the fund yarns --24-- and parts of the Florfasern --26-- were fastened. In similar way the melted fibers unite --28-- with the core --18--, and melted material from the layer --20-- one solidifies and with the core --18-- and the layer --14-- integrated. The melted I0 layer --20-- can be wasserundurchlässig, if it contains a melted plastic foil. From the managing it results that with heat and pressure the layers --12, 14, 16, 18 and 20-- to be integrated with one another and solidified, whereby a laminate will receive, which exhibits a very high interlaminate shearing strength. The received laminated material decorated tile--30--, as it is represented in Fig.4, becomes from the press --23-- taken out and at ambient temperature cooled down. With the cooling the laminated material decorated tile keeps --30-- their form and shows resistance to deformation, accuracy to size and firmness. Further the laminated material decorated tile shows --30-- favourable characteristics concerning Schallund thermal insulation. The laminated material decorated tile --30-- thus use can find for the arrangement of the interior, in particular for the lining of the passenger compartment of automobiles. A special advantage according to invention used of the material is the early to the difference to the materials, so e.g. splinter wood pressed by shaped parts from used for the arrangement of passenger compartments, that the individual components can be formed in a simple manner depending upon the needs of the application purpose and be adapted also in very favorable way to the environment. Compared to forming hard splinter wooden plates, as they found so far use, according to invention the production rate is substantially increased, and by the suitable selection of the type of artificial fiber it is possible without difficulty to lower the danger of fire within the vehicle substantially. Further one can prevent by suitable selection of the artificial fibers that in case of a fire poisonous gases are formed. With forming out the pressure plates --24 and 25-- the laminating press --23-- can regarding the desired form and training of the final product which can be manufactured --30-- on it consideration to be taken that different surfaces of the manufactured articles in the press in a higher or a smaller measure are pressed together, whereby the hardness, thickness and indulgence of the manufactured plate can be varied concerning different disk ranges between rigid zones, in those screws od.dgl, to be attached to be able, and soft zones with considerable insulating capacity. Thereby that the innene layer --18-- a loose filling contains, is the sandwich layers --16 and 20-- so far apart that the manufactured plate --30-- after laminating sufficient stiffness possesses and as self-supporting bodies to be manufactured can. The invention becomes in the following one on the basis a remark example of a laminated material - decorated tile in not restrictive way more near described: Example: A fünfschichtiges laminate with structural integrity and sound absorption ability were manufactured for the cover of the transmission tunnel. The core of the laminate consists of the layers --16, 18 and 20--, which were manufactured as follows: The situations --16 and 20-- consist of two felt layers with a weight per unit area of 410 g/m2 and consist of 50% polypropylene fibers with 16,5 dtex and a length of 7,63 cm and 50% polypropylene pile fibers with 3,5 dtex and a length of approximately 6.35 cm, whereby the felt courses were manufactured through stuff and needles. By stuff and putting of a felt course with a weight per unit area of 800 g/m2 from 50% Polyesterstapfelfasern with 6,7 dtex and a length of approximately 7.63 cm and 5% polypropylene pile fibers with 3,4 dtex and a length of approximately 6.1 cm the layer becomes --18-- manufactured. The layer --18-- becomes then on the layer --16-- applied and with this ennobles. The two-layered course is then led by a further Nadelstuhl, where the layer --20-- subsequently, to the layer --18-- one applies. In each of the two cases a Nadelstuhl is used, which exhibits Nr.32 needles with nine blows and in a distance from 18 Nadeln/cm, and whereby the needles in-sting about 1.27 cm deeply, so that the thickness of the manufactured Textilschieht in not squeezed together condition about 1 cm amounts to. Layer --14--: A felt layer with a weight per unit area of 350 g/m2 is manufactured through stuff and veins by black polyester yarn with 1,65 dtex and a length of approximately 7.63 cm. The layer becomes so far with layer --20-- vernadert that a mechanical Entlaminierung is prevented. Then the manufactured laminated material is turned and brought into a hot-air rotating furnace, in which about 85% of the air flow become passed through the laminated material I0. The air temperature in the furnace amounts to 185°C and the retention time is in such a way selected that a softening and partial melting of the polypropylene fibers in the situations --16 and 20-- it arises, however not in the measure that melted polypropylene begins to flow. In a separate station the surface decor cloth, a getufteter polypropylene carpet with a thickness in the not squeezed together condition of approximately 0.763 cm, over the laminated material heated up is put and immediately after withdrawing from the furnace in direct contact with the surface --16-- brought. Subsequently, in such a way received fünfschichtige material is brought directly into a laminating press, which remains closed so for a long time, until the interior temperature of the Schichtkörpers sank under for instance 116°C. If the manufactured plate is released from form, before sufficient cooling entered, throwing and a deformation of the manufactured shaped part arise. In the form metallic distance retaining panels are arranged in such a way that after reasoning a distance from approximately 0.51 cm remains to the form between parallel surfaces. The pressure expenditure-practiced in the laminating press amounts to about 276 kPa. At the manufactured plate the following physical characteristic data was determined: With 82°C and a relative air humidity of 95%, rigidity 450 g measured in the Gurley Steifigkeitstestgerät (sin e = 0.817), apparent density 0.40 g/cm3, density 0.82 g/cm3, peeling firmness (laminate shearing strength) protects thick 0.763 cm, weight per unit area 3020 g/m2, bending strength on the average about 17250 kPa, breaking strength in manufacture direction about 700 N/cm, breaking strength transverse to the manufacture direction about 525 N/cm, inherent stability about 1.0% maximum deformation (shrinking or expansion) about 14 N/cm.
