    The invention relates to a spacer fabric having a first and a second flat knitted fabric layer running in a production direction and stitch rows running in the cross direction, and monofilament spacer threads and multifilament spacer threads connecting the two. connect knitted fabric layers together. The invention further relates to a preferred use of the spacer fabric.
    Spacer fabrics are characterized by a light, breathable structure. In order to achieve thickness direction elasticity, monofilament spacer threads are used which, due to their thread structure, provide a significant recovery moment when compressed, so that the whole spacer fabric has very good elastic properties due to the large number of spacer threads.
    Based on these properties, spacer fabrics can be provided as elastic layers in mattresses, upholstered furniture, clothing or shoes that allow air circulation. Spacer fabrics are also used as technical textiles in the automotive sector, for example for child seats and seat covers, because of their cushioning properties and the very good resilience behavior, spacer fabrics also allow a good contour fit in their usual application.
    Compared to other materials in a thickness direction elastic materials, such as layers of latex or foam, the open, airy structure of the spacer fabric results in a lower basis weight with improved air circulation. Against this background, spacer fabrics can be supplied, for example, as functional layers, cover layers or covers for mattresses.
    Another advantage is that, in the case of spacer fabrics, the elasticity results from the provision of the spacer wires, which usually do not themselves have to be formed from an elastic material. Especially with synthetic elastomers, there is a problem that plasticizers can migrate oligomers and other volatile organic components and can therefore, for example, be used as a fragrance by a user.
    - 2 = be observed. In contrast, conventional, relatively simple thermoplastic materials such as polyesters, polyamides and polyolefins can be used for a spacer fabric.
    Because of the materials and the open, airy structure, spacer fabrics used in a mattress construction or as mattress topper can also be hygienically and effectively cleaned.
    A spacer fabric and the use of the spacer fabric as a mattress cover material are known from DE 20 2018 105 647 Ul. Optimized for use as a mattress protector, the spacer fabric is characterized by good stretch both in the production direction and in the transverse direction. The stretch properties are largely homogeneous in the plane, so that a contour adaptation to the mattress core is achieved without creasing or excessive tension. The spacer fabric is particularly light and relatively thin like a mattress cover.
    DE 20 2018 105 647 Ul forms with the documents DE 196 15 187 A1, DE 2 971 787 Ul, DE 2 957 662 Ul, DE 20 2005 013 361 Ul, WO 2006/122614 A1, DE 10 2005 060 931 A1, DE 10 2007 059 274 A1 and DE 199 31 193 A1 further prior art relating to the use of spacer fabrics in mattresses.
    A spacer fabric with the characteristics of the preamble is known from DE 199 10 785 B4. The spacer fabric accordingly has a first and a second flat knitted fabric layer, which have mesh stitches running in a production direction and stitches in a transverse direction, with the two knitted fabric layers on the one hand with monofilament spacer threads and on the other hand with multifile spacer threads. are connected to each other.
    While the monofilament spacer threads are provided to provide the elastic recovery properties, the additional multifilament spacer threads enable improved moisture transport in the thickness direction. In particular, for this purpose, the multifilament spacer threads can be formed from natural fibers which have at least some degree of hydrophilic properties.
    With the spacer fabric, one of the layers has
    - 3 = knitted fabric ribs which run as a sealing surface in the production direction, and which are interrupted by air-guiding channels. The spacer threads between the two knitted layers are omitted between the air guiding channels. Due to the openings of the ribs running in the production direction and the absence of spacer threads, an extremely low strength is created by the channels. The spacer fabric can be pressed in very easily there. In addition, there is also a particularly low stability in the transverse direction. Because of the channels, the material can very easily be pushed together in the transverse direction, whereby at least the knitted layer provided as a surface close to the skin and the spacer threads cut along the channels cannot provide significant resistance.
    Thus, the spacer fabric has a low overall stability and strength. There is even the risk that the ribs running in the production direction tilt laterally in the unsupported air guide channels when loaded with weight, so that the desired liquid transport is then no longer possible. With such a relatively strong deformation, the monofilament spacers are also very strongly bent or kinked. When conventional thermoplastic polymers are used for the spacer threads, a crackling or cracking noise is often perceived, which may be perceived as unpleasant by a user.
    Against this background, the present invention is based on the object of specifying a spacer fabric which is on the one hand extremely soft and deformable and on the other hand has good elastic properties. A further object is to provide a particularly preferred use of the spacer fabric.
    The object of the invention and the solution to the problem are a spacer fabric according to claim 1 and a use of the correct fabric according to claim 20.
    Starting from a generic spacer fabric, the invention provides that the spacer threads are arranged in the transverse direction in first groups, each having at least two consecutive monofilament spacer threads and second groups, each having at least two consecutive multifilament.
    - 4 - distance wires.
    According to the invention, there is a functional distribution, where the elastic resilience properties are provided essentially by the monofilament spacer threads, as is conventional per se. Then between the first groups, each having at least two consecutive monofilament spacer threads, there are second groups, each having at least two consecutive multifilament spacer threads. The multifilament spacer threads therefore fill the space between the monofilament spacer threads, so that the multifilament spacer threads of the second group allow for a certain filling and buffering effect. The multifilament spacer threads are relatively soft due to their structure, each with a large number of filaments, but still lead to some stabilization of the material.
    While in the prior art channels running in the production direction are formed and the knitted spacer fabric can tilt there, in accordance with the present invention the areas that run longitudinally along the multifilament spacer yarns are particularly soft, but are lined or filled by the fabric. multifilament spacer wires. Complete compression of the two layers of fabric or a sideways tilt can be avoided. In all cases, a complete collapse of these soft areas can be prevented.
    Although the multifilament spacer threads appear relatively dense to an observer due to their structure, some amount of air circulation can still exist even when exposed to pressure.
    According to a preferred embodiment of the invention, it is provided that a complete coverage with spacer threads is provided in the transverse direction. Thus, in total, at least one, preferably exactly one, multifilament or monofilament spacer thread is provided for each rib. This property refers to the number of spacer threads and mesh threads in general, whereby of course the individual spacer threads can be worked with their knitting pattern across different mesh threads.
    If, according to a preferred embodiment of the invention, the spacer wires are formed with a plurality
    - 5 = shelves, the individual shelves are then effectively covered with spacer wires where the other shelves remain empty.
    At least when there are no transverse channels described in more detail below, there is preferably a spacer thread in the transverse direction on each stitch of the two knitted layers.
    The complete coverage of spacer wires in the transverse direction can also be seen when the spacer fabric is cut in the transverse direction.
    It is expediently provided that the first groups and the second groups alternate in a regular sequence in the transverse direction. Areas with good reset properties and high elasticity therefore alternate regularly with comparatively soft areas. In the case of a regular sequence, a macroscopic approach thus forms a medium homogeneous material that can also be cut to any size.
    In order to achieve good functional properties with regard to the usual dimensions and purposes of use, according to a preferred embodiment of the invention it is provided that the first groups are each between four and three, particularly preferably between six and twenty, for example eight consecutive monofilament spacer threads in the transverse direction.
    In a preferred embodiment, the second groups, on the other hand, have between two and twelve, particularly preferably between three and six, multifilament spacer threads that follow each other in the transverse direction. Where the multifilament spacer threads of the second group are arranged, the spacer fabric can also be bent slightly at fold lines running along the production direction, the soft areas also contributing to a pleasant, particularly smooth feel.
    Usually two to twelve, and particularly preferably three to six multi-filament spacer threads one behind the other in the transverse direction are sufficient to achieve these properties. The four to thirty and preferably six to twenty consecutive monofilament spacer threads of the first group, on the other hand, allow sufficient stability and facilities to be achieved.
    In the usual sizing of a spacer fabric, the different areas formed thereby are so small or so narrow that, for example, the different structure can be seen with one hand, but this is not perceived as unpleasant. Rather, in a user's perception, it is the result of the structure of the ribs, as is also known and familiar with other materials such as latex or rigid foam.
    The numerical ratio of monofilament spacer threads to multifilament spacer threads (including the range limits) is typically between 4: 1 and 1: 1, preferably between 3: 1 and 1.5: 1, for example 2: 1. Taking into account the different structure and the different functional arrangement, according to a preferred embodiment of the invention, it is provided that the monofilament spacer threads of the first group on the one hand and the multifilament spacer threads of the second group on the other hand have a different layer, i.e. another layer pattern.
    For example, the monofilament spacer threads of the first group may have a layer selected from the categories X layer and I-X layer. In the case of an X layer, the monofilament spacer threads have an offset in the transverse direction in their course in the production direction. The spacer wires are passed over different mesh wires accordingly. In the case of an X layer, the spacer wires are crossed together when a cross-section is viewed in the transverse direction. Such an X-layer can be achieved, for example, by knitting the monofilament spacer threads with two Le-webs, which have opposite movements, i.e. undergo opposite displacement in the transverse direction.
    In the case of a preferred I-X layer in the context of the invention, monofilament spacer yarns incorporated into an X layer may be combined with further monofilament spacer yarns running in an I layer along an associated mesh yarn. The I-X25 arrangement is particularly preferably implemented such that the individual threads are guided alternately laterally offset over at least one mesh yarn and knitted along an associated mesh yarn in the production direction.
    - 7 = In contrast, the multifilament spacer threads of the second group preferably have an I-layer. The multifilament spacer wires then always run along a reversed mesh wire. This results in a shorter thread length compared to an X or I-X layer, whereby the desired damping effect or buffering effect of the multifilament spacer threads can also be achieved in the I layer.
    All spacer wires are preferably formed from thermoplastic polymer.
    The multifilament spacer threads may have a fineness of between 30 dtex and 168 dtex, in particular between 49 dtex and 111 dtex, where the multifilament spacer threads may be formed from a number of between ten and seventy-three, particularly preferably twenty-three and forty-nine. filaments. For example, a textured multifilament yarn with a fineness of 76 dtex is suitable, which is formed from thirty-six filaments.
    When, in a preferred embodiment, textured multifilament yarns are used, the specified value of the fineness refers to the nominal titer, i.e. the fineness of the multifilament yarns in the untextured state. After texturing, the unstretched state of the multifilament yarns typically has about 5% to 20% higher effective titer values.
    In contrast, the monofilament spacer threads preferably have a fineness between 43 dtex and 245 dtex, particularly preferably between 54 dtex and 157 dtex, for example 108 dtex.
    The two knitted layers can be formed in various ways, considering both monofilament yarns and multifilament yarns. However, an embodiment is preferred in which the cover layers are formed from multifilament yarns, the cover layers being the yarn also used for the multifilament spacer threads. The advantage then arises that, at least for the multifilament spacer threads and for the two cover layers, no different threads have to be kept ready.
    According to the invention, regions of different elasticity and hardness are generated by the
    - 8 - alternating first group and second groups in the transverse direction.
    According to a further development of the invention, comparable measures can also be performed by varying the knitted distance in the production direction.
    Thus, according to a preferred embodiment of the invention, at least some of the spacer threads are guided within the associated knitted layer in the production direction to form transverse ribs running in the transverse direction.
    For example, if all monofilament and multifilament spacer threads are guided in a respective assigned knitted layer, channels are formed extending in the transverse direction, as is also known in principle in the art.
    In the context of the invention, however, it may also be sufficient if only the monofilament spacer threads at the transverse ribs are guided in a respective associated knitted layer, whereby a lower strength and a higher flexibility of the material are also achieved along the transverse ribs. .
    It can be provided that the width of the transverse ribs defined along the longitudinal direction is two to twelve, preferably three to eight and, for example, four mesh rows.
    The distance between two consecutive transverse ribs can be between six and twenty-four rows, preferably between eight and sixteen rows and, for example, twelve rows.
    The specific configuration of the two knitted fabric layers is not limited within the scope of the invention.
    At least one of the knitted fabric layers may also have openings formed by a number of meshes, for example, to achieve improved air circulation and / or good in-plane stretchability of the corresponding knitted fabric layer.
    For example, the first knitted layer may each have openings formed by a plurality of stitches.
    A two-wire system with fillet pattern can be provided for this.
    A corresponding configuration is known for a knitted spacer fabric, for example from DE 10 2016 125 881 B3. With regard to general specialist knowledge, reference can also be made to the specialist book "Wirkerei und Strickerei", Markus Oliver Weber / Klaus-Peter Weber, 6th edition 2014, Deutscher Fachbuchverlag GmbH, pages 188 to 189. In the in particular, a body jersey can be provided
    - 9 - with two shelves and a corresponding indentation 1 full, 1 empty.
    The second knitted fabric layer can in principle also be provided with openings. As a rule, however, a uniform active structure without openings, each formed by a number of meshes, is suitable. For example, a body jersey is suitable here, which can also be produced with an overlay. A corresponding body jersey is shown, for example, in the specialist book "Wirkerei und Strickerei", Markus Oliver Weber / Klaus-Peter Weber, 6th edition 2014, Deuter scherbuchverlag GmbH, page 185 (Fig. 7.111), where of course also without limitation other laying patterns can be considered.
    The thickness of the spacer fabric can be adjusted within a wide range. In a preferred application as a cushion layer in a mattress or a mattress cover, the thickness may typically be between 5mm and 30mm, especially between 8mm and 16mm.
    As explained at the outset, the advantage of a spacer fabric is that the elasticity is provided by the wire structure of the spacer wires and in particular the monofilament spacer wires, while the spacer wires are usually formed from a non-elastic thermoplastic polymer. The knitted layers and the spacer threads can be formed, for example, from various materials and in particular polyester such as, for example, polyethylene terephthalate (PET). Of course, other materials such as polyamide or polyolefins can also be used, but it is especially preferred that the entire spacer fabric is made of one type and therefore can also be easily recycled.
    The invention also relates to the use of the spacer fabric as a cushion layer in a mattress or top mattress. This also includes intermediate or covering layers of box-spring beds, futon beds or the like.
    Due to its particularly advantageous properties, the spacer fabric is of course also suitable for other applications. The spacer fabric can also be used for, for example, seats, vehicle seats, textiles or general elastic liner.
    The invention is explained below with reference to a drawing which illustrates only one embodiment. It is shown in Fig. 1 shows a spacer fabric according to the invention in a schematically simplified perspective view, FIG. 2 is a cross-sectional view in transverse direction, FIG. 3 shows the top view of a first knitted layer of the spaced knitted fabric, FIG. 4 shows the top view of a second knitted layer of the spaced knitted fabric, FIG. 5 shows an example of a spacer thread laying pattern of the spacer fabric.
    FIG. 1 shows a schematic and highly simplified illustration of a spacer fabric having a first flat fabric layer 1, a second flat fabric layer 2, the fabric layers 1, 2 running in a production direction P and having mesh rows extending in a transverse direction Q. The fabric layers 1, 2 are interconnected by monofilament spacer threads 3 and multifilament spacer threads 4.
    It should be noted that, according to the figures, the typical structures of the fabric layers 1, 2 and the spacer threads 3, 4 are shown by way of example only, and in particular not all threads and in particular not the intertwining of the wires are shown in detail.
    With regard to the ridges which are substantially parallel to each other in the production direction P, in the example shown in the transverse direction Q, a complete covering with spacer wires 3, 4 is provided, the spacer wires according to the invention in the transversely Q are arranged in first groups 5, each with at least two consecutive monofilament spacer threads 3 and second groups 6 with at least two consecutive multifilament spacer threads
    4.
    The division into the different groups 5, 6 of spacer wires 3, 4 is also clear in Figure 2, where the correct number is not easily readable from the viewpoint of visibility. It should also be taken into account that
    With a corresponding representation in the transverse direction Q, several spacer threads 3, 4 consecutive in the direction of production P may be visible simultaneously.
    Within the scope of the invention, different zones are formed by the first groups 5 and the second groups 6. The first groups 5 made of monofilament spacer threads 3 offer the classic reset properties typical of spacer fabrics, while in the field of the second groups 6 locally reduced compression hardness is provided by the multifilament spacer threads 4 disposed there. In the region of the second groups 6, the spacer fabric can therefore be bent and compressed particularly easily, so that in general a particularly good contour fit for a user results when the spacer fabric is provided, for example, as a covering, coating or cover layer of a mattress. It must also be taken into account that the spacer fabric is not only compressed, but also three-dimensionally deformed and bent at a certain angle. Such an adaptation is possible in particular because of the soft zones formed in the region of the second groups 6.
    The preferred configuration of the fabric layers 1, 2 described below allows good stretchability in the production direction and transverse direction Q and thus contributes to a good adaptation of the shape.
    The multifilament spacer threads 4 provide a certain buffering and cushioning function despite the generally low compression hardness. Because of the multifilament spacer threads 4, the spacer fabric cannot be fully compressed (and block) there either. It is also possible to prevent sideways tilting of the monofilament spacers to a certain extent.
    A comparative consideration of Figures 1 and 2 also shows that the first groups 5 and the second groups 6 alternate alternately in a regular sequence in the transverse direction Q. For example, the first groups 5 may contain between four and thirty, in particular between six and twenty, consecutive monofilament spacer threads 3 in the transverse direction.
    - 12 - have ting Q.
    The second groups 6 can each have between two and twelve, in particular between three and six, multifilament spacer threads 4 that succeed each other in the transverse direction Q. The ratio of monofilament spacer threads 3 to multifunctional spacer threads 4 can be, for example, between 4: 1 and 1: 1, in particular between 3: 1 and 1.5: 1, for example 2: 1.
    The exemplary embodiment is based on a configuration with eight monofilament spacer threads 3 of each first group 5 and four multifilament spacer threads 4 of each second group 6, even if not shown in terms of their number in Figure 2 based on the schematic. display are identified.
    Already from the schematic representation of FIG. 2, it can be recognized that the monofilament spacers 3 on the one hand and the multifilament spacers 4 on the other hand are arranged differently. While the multifilament spacer threads 4 have an I-ply, the monofilament spacer threads 3 are provided with an intersection with two ply webs, hence the characteristic X shape is marked in Figure 2. A particularly good kink stability is achieved by crossing the spacer threads, so that the two fabric layers 1, 2 cannot slide sideways against each other.
    Against this background, the typical X structure in Figure 2 emerges even when the monofilament spacer wires 3 are arranged in an I-X position in the illustrated embodiment (see below for Figure 5).
    Figure 3 indicates that the first fabric layer 1 may have openings 7, each of which is formed by a number of stitches. The openings 7 can be created, for example, by filleting with two layers. It should also be noted with regard to Figure 3 that the proportions are not to scale and the openings 7 are shown relatively large for better visibility.
    Figure 4 shows a view of the second fabric layer 2, which is formed with a laying web like a body sweater and which has no openings formed by a plurality of stitches.
    FIG. 3 and 4 indicate that in the production direction P transverse ribs 8 are formed at a recurring distance of
    13 = for example six to twenty-four and especially twelve webs, on which at least some of the spacer threads 3, 4 and in particular all of the monofilament spacer threads 3 are formed in a respective fabric layer 1, 2. In particular, according to the As an example, all spacer threads 3, 4 are guided in an associated fabric layer 1, 2, so that the transverse rib 8 then forms a channel extending in transverse direction Q.
    In a manner similar to that along the second groups 6 of multifilament spacer wires 4, weakened areas of low strength are also formed in the transverse direction Q, which, however, according to the exemplary embodiment, are completely free of spacer wires 3, 4. With such a configuration, also a particularly good unwinding is achieved along the thus formed transverse ribs 8, so that the described material can also be deformed well in all directions in three dimensions.
    The width of the transverse ribs 8 defined in the direction of production P can be, for example, between two and twelve, and in particular four tracks.
    FIG. 5 shows a cross-sectional view of a laying pattern only for the spacer threads 3, 4. Accordingly, the monofilament spacer threads 3 have an IX lay, this IX lay being formed with two opposite lay paths, for each first group 5 with eight monofilament spacer threads 3, each of the two layways is covered with four monofilament spacer threads 3. The monofilament spacer threads 3 assigned to the different layouts are solid on the one hand and dotted on the other hand.
    In contrast, the multifilament spacer threads 4 are knitted in an I-ply. To form the transverse ribs 8 described above, all spacer threads 3, 4 are guided in a corresponding fabric layer 1, 2. In principle, in order to produce the desired weakening, it may also be sufficient if only the monofilament spacer threads 3 are guided in an associated fabric layer 1, 2, while the multifilament spacer threads 4 remain as pile threads between the knitted layers 1, 2 walk.
