Description

[Detailed description of the invention]

The invention comprises a top layer comprising fibers or filaments and a support layer, both layers encapsulating between themselves an inner layer of granular filler material, through which the The present invention relates to the use of rounding flat layered structures in the field where textiles are used as needle-punched and bonded to each other, cushion elements, floor coverings or wall coverings or the like.
In the known layer structure (according to DE 25 44 855) of the type described in Section 1iK, the two covering layers are sutured to one another via a layer of granular filler material. In this case, these filler layers must consist of a material that does not have a defined round shape in itself so that it can be penetrated by a needle when being sutured. In this known Q-layer structure, the advantageous filling material used is a synthetic foam material, which is particularly light in weight. The use of this known layer structure is limited by the nature of the filler material used. The stitching of this layered structure is a very expensive process, which requires expensive sewing threads. If the suture thread is damaged, there is a risk that the seam will tear and the retention of the filler material between the seams is no longer guaranteed. Furthermore, jutans are known in which, between the support layer and the upper layer, a loose fibrous material consisting of a repellent material of manufacture is bonded by needle punching. The problem underlying the present invention is therefore to create a layered structure of the type mentioned at the outset, which can be used in many ways and is not restricted to filler materials. According to the invention, the top layer and the support layer are needle-punched through an inner layer containing granular particles of at least one mineral inert substance. It is solved by Due to the fact that the covering layers are bonded to one another by means of a needle-punching process, the layer present in the middle of the covering layer, which contains granular particles of at least one inert mineral substance, advantageously contains a large number of fibers. Alternatively, the particles may be mixed with threads and the particulate particles are held in place by these fibers or threads. As a result, the layered structure obtains its own retention, in which case, for example, the threads or fibers are damaged and a nine-edge needle punching process is possible in the damaged areas. This is because the needle-punched fibers or yarns are not bonded to each other. This ensures that particles only escape from damaged areas, for example. This is because other needle-punched areas act like closed rods. This makes it possible, for example, to achieve a uniform mixing of the particles with the fibrous material and a good distribution of the particles - which cannot be achieved, for example because of the idea of stitching the covering layer, and (9) by conventional needle-punching methods. It can be done in a cheap way. The flow of the granules within the layered structure is completely prevented, so that a three-dimensional shape is achieved which can be used in many ways as a patterned body made of fiber material of the layered structure. The addition of heavier granules increases the overall weight of the shaped body, which has a very advantageous effect in various applications. The granular particles used according to the invention, especially if the particles are sand or gravel, are brittle and/or have abrasive properties) and have abrasive properties during the needle punching process. &1'l hardness. However, small pieces have properties that are inherently unsuitable for needle punching due to the material they are made of. Surprisingly, however, the surface layer and the support layer can be formed by conventional needle punch processing techniques, i.e. by needle punch needles with barbs, e.g. normal felting needles, without damaging the needles, e.g. It has been found that needle punching can be performed through a layer of granular particles without causing any damage. This is partially due to the fact that the small pieces of granules shift relative to each other during the needle punching process, and the small pieces that are hit by the needle during the needle punching process escape to the side. attributed to. The layered structure according to the invention can advantageously be used as jutan, in which case the sand is present, for example, in an areal weight of 100 to 100 of, A''. This makes it possible to produce heavy jutan at reasonable costs, This jutan has a high noise-improving substance and a high degree of sound absorption compared to the warmer jutan. It can be used as a support as well as a cushioning element.Furthermore, due to its weight, this layered structure is suitable for shaping into strips as a weighted belt.In the field of use for large men, this layered structure is suitable The body insert is applied, for example, as a strip, but it is of course also possible to combine multiple, especially two-layer structures and use them, for example, as cushions, bags or hoses.In its simplest form: The inner layer of the layered structure consists exclusively of granular sand, which makes it possible to create floor coverings that can be used, for example, as self-adhesive heavy dune mats, in which case this du dune floor conforms to the unevenness and adheres tightly. As a self-contacting jutan, the sand layer Sono Seikyusha 2~
7#l/m2. Since such a layered structure has no seams, it can be cut and then used, for example, as strips or as paving stones. If the layered structure is divided into small pieces, such as this paving stone, for example, the pieces will flow out only in the areas directly in contact with the cutting machine. This is because the individual pieces are each held by the holding fibers pierced as described above. child

[The top layer and the covering layer are not sutured to each other by trapping sand-like particles between them, as was conventionally done.
This becomes possible only when they are connected to each other by needle punching. Such a layer density over the entire surface of the layered structure can only be produced by needle punching, and this layer density cannot even be imagined by stitching. This style of Jutan shingles and especially Jietan-like paving stones need not be affixed to the floor. This is because they rest tightly against the floor due to their own weight. Furthermore, when using an inner layer of rock chips, such as sand or the like, it is also possible to add a binder in this layer, for example cement or the like, or a synthetic resin. When cement particles were added and 9-diathane was applied to the wet surface,
Jutan bonds with this surface and hardens. The filling material may be formed by granular cement, barite, or light metals such as, for example, aluminum hydroxide or the like. These materials, including the sand or gravel mentioned above, improve the properties of the layered structure with respect to its behavior in the event of a fire. In particular, such a layered structure is highly regarded as a fat burning material. The layered structure according to the invention can also advantageously be used as wall covering. In this case too, a binder such as cement or synthetic resin is added to the inner layer. To prevent the layered structure from falling prematurely during the hardening with the wall, the layered structure is fastened to the wall with nails, bottles, etc. during installation and hardening. The nail or pin can be driven through the layered structure without destroying it and can be removed again after the hardening process has ended. Since at least the upper layer is elastic, holes caused by nailing etc. will close naturally after the nail is pulled out. Because the layered structure according to the invention can be cut into differently shaped parts, it is particularly suitable for use as a cushion, for example on a sofa or an armrest. In the layered structure according to the present invention, when sand is used as granular pieces, the layered structure has good fire prevention properties because sand has a large heat capacity and poor thermal conductivity. A wall made of fibrous material, conventionally supplied as S-flammable, behaves even better when it is filled with sand. The layered structure according to the invention can therefore be used, for example, as a so-called "iron curtain" and has an optically pleasing appearance due to its fiber material construction. If 0.02
Grains 11 of ~21111 are preferred. These layered structures can be constructed in various weights and resulting full thickness timbers to suit the particular application. For example, if sand is present as granular particles, the area weight of the particle layer KTo is 4#/-, and the total thickness of the wood is approximately 4-5cm, while the area weight of the particle layer is approximately 12 kg/ml. The layer structure has a total thickness of approximately 8 to 10 m II. Depending on the desired total layer thickness of the layer structure, the fibers or threads from which the paving stones are made may be The material extending through the thickness from the top layer to the carrier layer has a length sufficient to allow active needle treatment, especially from 40 to 120 m. Both these layers are then bonded to each other by a needle punching process over the entire surface of the layered structure such that a sufficient needle punch density of, for example, 50 to 200 Pa/te/d is achieved over the entire surface of the layered structure. If necessary or desired, the layered structure can also be treated from the top layer or from the carrier layer (in other configurations), the carrier layer may be coated with fibers. It may also be made of a material, for example a synthetic material sheet, which does not contain a 9-layer structure, making other structural configurations of the nine-layer structure possible, with at least the carrier layer comprising, for example, a reflective layer, For example, it is provided with a metal layer. Textile strips or fleece materials can also be used as carrier layers for passively needle-punched tubes. In a preferred embodiment, the carrier layer is shaped, for example, in the form of a bowl or in the shape of a square. The web can be formed and filled with small pieces and provided with nine recesses.The recesses can therefore be curved and wound in a particularly advantageous manner around the web between the recesses, for example of special flexibility. A layered structure can be obtained in which the covering layers are needle-punched and bonded to one another in the areas where the recesses are not formed, and are not needle-punched in the areas where the recesses are formed. Depending on the particular field of use, the retaining fibers are drawn into the recessed carrier layer at different depths, i.e. the penetration depth is on the one hand > shorter than the height of the recess; The carrier layer is not pierced by the needles.However, if desired on the other hand, a deeper penetration depth can be selected, in which case the retaining fibers may also penetrate the bottom of the recess. An intermediate possibility is that the bottom of the recess is pierced with the needle tip, but the retaining fibers are not drawn downwards to the bottom K, penetrating the sand layer that connects the top layer and the carrier layer to each other. The individual sand bodies between the covering layers are elastically held by the holding fibers, and the layered structure as sand bodies can be spread.
The individual particles do not significantly change their position within the layer structure. As the upper layer, for example, uniform rotsuba published patent publication (Mu1) 0

If 11*9 spherical threads are used in the spheres as described in $428, a particularly dense top layer is obtained during needle punching, in particular from which powdery particles do not flow out. Other details and advantages of the invention are apparent from the appended claims and the nine embodiments described in conjunction with the following drawings. The drawing shows a partial area of the layered structure according to the invention schematically and enlarged in cross section. The layer structure 1 has an upper layer 2 which is positively needleable and consists of a fiber fleece or of a round yarn (FIG. 3) wound into a sphere as a spherical yarn. The at least passively needleable carrier layer 3 is a retaining edge which is ejected from the upper layer 2! It is held against this upper layer 2 by 114. Between the upper layer 2 and the carrier layer S, a layer 5 of granular particles 6 is provided. Both layers 2 and 5 are needle punched through this small layer 5]
and are connected to each other. Needle punch processing is

0, 1915-202, by needle punching methods known in the needle punching felt art. In this technique, a nine felt needle with a triangular needle shank and a nine inverted barb oriented toward the lateral tip is often used to perform the needle punch process. Other shapes of needles can also be used, such as fork needles or loop needles. The knitting needles described in the above-mentioned publications can also be used correspondingly for needle punching the layered structure 1. As the seven-elt needle penetrates into the upper layer 2, it picks up individual fibers 4 or bundles of fibers 40 from this upper layer and braids these fibers with the carrier layer 3. The upper layer 2 is positively needleable for this purpose. That is, the fibers can be drawn out of this layer, in which case the fibers 4 remain partially fixed within the layer 2. Not only are both layers 2 and 5 bonded to each other (by the needle-punching process), but also the layers 50 and granules 6 form the layered structure 1.
Lateral sliding is prevented by the retaining fibers 4 which are distributed over the entire surface of the retaining fibers 4 and are drawn through them. This makes it possible to cut the layered structure in any desired shape, in particular as strips or as paving stones, with a significant amount of small pieces (on the cut edges).
It won't fall down. In this embodiment, the layer 5 of granular particles 6 consists of rock particles having a small particle size, for example 0.05 mm, depending on the desired purpose of use.
It consists of sand with a particle size of 0.02 to 2.0 mm. However, it is also possible to use large pieces 6 (depending on the intended use). The advantages of this rock fragment are its relatively large weight for a given layer thickness, its relatively high heat capacity, and its inert behavior towards other materials. In this embodiment, the layer 5 of granular particles 4 consists of small rock particles with a grain size of, for example, J) 0.02 to 2.
It consists of sand with a particle size of 11 g. However, according to an embodiment not shown, coarse sand and gravel and even fine-grained stone chips can be used, as long as they do not interfere in any way with the felting needle. In addition to sand, there is also 9 in this layer 5, particularly in the form of powder instead of binder particles (and which have not been bothered to be shown in the drawing 1 for clarity).
Substances such as cement, gypsum, lime, etc. may also be included in powder form. As is clear from the drawing, the carrier layer S can consist of various materials. This support layer 5 is pushed open at the nine ends through which a needle is inserted, and holds the holding fibers 4 that have been inserted therethrough, for example, elastically and, for example, by tightening and knitting. That is, the support layer S
can be passively needle punched. This includes 11 e.g. synthetic materials made of soft elastic materials.
The seed door (see, for example, FIG. 2), during the needle-punching process of sufficient deformation, is itself further densely packed or packed with fiber layers - these hold the particles 6 - as well as the fiber agglomeration which is viscously bonded. Materials such as fleece material or spunbond materials are suitable. The carrier layer 5 can itself be actively needle-punched, so that the layer structure 1
As shown in the right half of FIG. 4, needle punching can additionally be performed from the opposite side. It is also possible for the layer structure 1 to be needle-punched from both sides, with a further actively punchable fiber layer below the synthetic material sheet or the like as support layer 3. The carrier layer 3 can furthermore be formed as an elastic backing itself or can be provided with an elastic backing on the side facing the upper layer 2 (not shown diagrammatically). The fibrous layer, whether as the upper layer 2 or as the carrier layer 5, can be pre-compressed by needle punching separately, for example by needle punching KJI fiber composite material on the carrier layer such as a synthetic fiber sheet. to facilitate handling during manufacturing and/or to place fine sand particles 6, especially binder particles 1.
3 (see FIG. 5) can be prevented from flowing out of the layered structure 1 prior to needle punching. There are various fiber materials for the fiber fleece and the spherical yarn (see FIG. S). Textured fibers wrinkle.I
! Natural or synthetic fibers such as cotton, wool, animal hair fibres, etc. or mixtures thereof are suitable for this purpose. The layered structure of the embodiment according to Figure #11 only has distributed, fine, sand-like rock particles. In this case, the rock fragments are present with an areal weight of about 100 to 1000 y/m2. For example, according to the embodiment of the present invention, it can be improved. Conventionally, nine diethanes formed in this way have approximately 700 ~
It has an areal weight of 1 lo 011/m", but its weight increases by about 50% by adding about 4007 m2 of fine sand. By loading the sand particles 4 into this jutan, the relative The hardening effect/softening effect can be obtained by any method, thereby improving the degree of improvement of walking noise and increasing the sound absorption.Sand with an area weight of 2 to 71□l112 is added to the jutan, and within this jutan, When needle-punched, this jutan can be used as a strip, in particular as a jutan-like slab (self-corrosive), and it has to be glued to 1% A0 layered structure according to the embodiment according to FIG. 4 can be used as a curtain, in which case the layered structure behaves particularly well in a fire due to the addition of sand particles, for example 1 to 2 II
Since the sand present with a grain size of II and an area weight of 0.5 to 2°5 #/311' has poor thermal conductivity and high heat capacity, the layered structure of the keratin layer can be used as a fire protection-isolation curtain, e.g. the so-called 6 As shown in FIG. 2, a sheet of synthetic material 7 with a recess 8 obtained, for example, by deep drawing in a thermoplastic state, can be used as an iron curtain, for example in a theater or as a spark protection curtain. The recesses 8 are shaped like small bowls (according to FIG. For example, the recesses are arranged so as to be offset from each other.In this case, the recesses are open in the two directions of the upper layer, and the particles 6 can be inserted into this I!1 position. (In the embodiment according to FIG. 2, the layers 5 of the strips 4 are flush with each other)
It has no structure and is divided into many parts. The needle penetrations are uniformly and densely distributed over the entire surface of the layered structure 1. This is indicated by the S small bowls on the left side of FIG. In this case, the retaining fiber 4 passes centrally through the bottom of the bowl-shaped section. The holding fiber 4 is
Corresponding to an embodiment not shown in ζζ, this retaining fiber ends at the bottom of the bowl in the area of the recess 8, but - The blade retaining fibers penetrate the synthetic sheet 70 into the unprocessed recesses 9, thereby forming the top layer 2 of the synthetic material 7 and bonding it with the support layer. In this case, during needle punching of the layer structure, the needle tip nevertheless punctures the bottom of the recess, so that liquid can flow from the side of the carrier layer 5 into the recess 8. be. As shown in the right half of FIG. 2, the top layer 2 comprises a synthetic sheet 7.
It is bonded to the holding fiber 4 only at the position 9 where no recess is formed. Although the bowl-shaped recess 8 itself is actually rigid, the layered structure 1 has a relatively large flexibility. Because working as a web,
This is because the position 9 where no recess is formed acts like a hinge. In the embodiment shown in FIG. 3 of the layered structure 1, sand particles 6 and relatively small particles, such as cement powder, which can be activated with water, are deposited on a support layer 5 formed as a fiber fleece. A spherical yarn 14 consisting of nine fibers wound into a spherical shape is placed as an upper layer on this layer. These S layers 2, 5 and 5 are needle-punched from above, in which case the retaining fibers 4 are removed from the spherical thread 14. This spherical thread-top layer 2 is particularly dense, so that no particles 6 or 1s are thrown off from the layer structure, and dirt particles falling onto the layer structure from the outside also fall onto this top layer 2.
It does not pass through. The layer structure according to the HS diagram is suitable for q# and for jutan due to its surface structure. By moistening the base on which this jutan is placed, in particular the retaining fibers 4 absorb moisture and bind the retaining fibers directly with the binder and to the binder 4 base. In the embodiment of the layer structure 1 according to FIG. 4, 60 rows 11 or strips of sand-like particles are placed as a carrier layer S on the actively needle-punched fiber layer. ing. These rows or strips are interrupted to form a dead intermediate layer 5, through which the needle punching process takes place. On this row of strips 6 an actively needlepunched fiber layer is placed as covering layer 2, and the layer structure 1 is needlepunched from above. On the right hand side of this figure 4,
This layer structure 1 can additionally be needle-punched from below, i.e. the retaining fibers 4 can also be removed from the upper layer 2.
It is also shown that it is removed from the carrier layer S. What these image configurations have in common is that they form a kind of hinge at the position 12 in which the particles are not held, so that the layer structure has a large number of particles 6 in the direction transverse to the extension of the layer particles.
As shown in the left half of Figure 4, even when a Particle size range of 60! From the table below, arranged in rows according to The thickness and layer density can be seen. If synthetic seeds are used as carrier layer 5, the sheet thickness is sO2, as in the embodiment according to FIG.

Example of Preparation of the Layer Structure 1 According to FIG. 1 Both the upper layer 2 and the carrier layer S#i were made from the same material in the following manner. A carrier sheet consisting of polyethylene with a thickness of 0.11) (not shown in the Is1 diagram) with a fineness of 5.5

The fibers, together with the sheet, are pre-needle punched with a conventional felting needle at a penetration density of 45 punches per d. The nine fibrous layers pre-needle-punched in this manner are placed on a supply table of needle-punched materials with the fiber tufts facing upwards, and then the particles @O, S ~ 0. 75m of washing nine quartz sand 7#/in
This layer is then covered in the same manner with a pre-needle-punched and well-edged layer, which is laid down with the fiber tufts facing downwards. Needle punch with a 25 gauge felting needle at the penetration rate of the punch. A layered structure with an area weight of about 7.4 #/ll2m is obtained. Layered structure according to FIG.
