The invention relates to a thread system (1) for installing in drinking water systems and other liquid guiding systems (T), said thread system having a multidimensional structure formed by at least one thread (200) which exhibits a germicidal activity in a damp environment due to oligodynamic metal parts in the thread. According to the invention, the thread system (1) is provided with a first surface structure (10), and a plurality of spacer thread elements (11) extends perpendicularly to the surface structure (10) in such a way that the thread system (1) forms an elastically deformable three-dimensional spacer structure, the thread (200) with the germicidal activity being arranged in the surface structure (10) and/or in the region of the spacer thread elements (11). The elastic properties enable the same thread system (1) to be used for a plurality of different drinking water systems. A volume unit of the thread system (1), which is larger than the spatial volume in the assembly region of the drinking water system, is introduced into the assembly region in a compressed manner. The thread system (1) is then left to expand, and sticks, with the surface structure (10) and the fibrous spacer sections (11), to the wall sections of the drinking water system (T) which define the spatial volume.

Description

THREAD SYSTEM FOR INSTALLING DRINKING WATER ISSUES AND OTHER LIQUID GUIDING SYSTEMS Description The invention relates to a wire system for installing in drinking water systems and other liquid guiding systems, in accordance with the preamble of claim 1. US Directive 98/83 defines drinking or drinking water as all water that: - is used as food; - serves for body cleaning purposes; - it is used to clean articles that are going to be in contact with food, or that, as they are intended, do not remain in contact merely temporarily with the human body. Water systems for drinking, or drinking water, and other liquid generating systems, are understood to mean, within the scope of the present invention, all systems that come into contact with drinking water, in accordance with the definition of US Directive 98/83, or with other liquids, correspondingly. According to the regulations of the German Law on Protection against Infestations (UfsG), drinking water must be such that the use of drinking water does not cause harm to human health, in particular due to pathogens. Water must meet both chemical and microbiological guidelines, or limit values with respect to the quality of drinking water. Thus, in accordance with the Regulations for Drinking Water (TrinkwV), it must not contain pathogens in concentrations that may lead to damage to human health. For example, no colibacteria (Escherichia coli), no enterococci or coliform bacteria should be detected in 1 00 ml_. With regard to legionella (for example, Legionella pneumophila), in Germany, there is an agreement in which hygienizing measures must be taken from a count of 1000 colony forming units (KbE) per 1 00 ml_. Since the observance of the parameters refers to 100 ml of water, some bacteria can occur very well in larger quantities of drinking water, that is, even when microbiologically satisfactory drinking water is fed to the construction facility from the water supplies (water deposits), bacterial pathogens can develop, even legionella, and can multiply under appropriate conditions. Each building or plant manager, therefore, is solely responsible for the quality of the water, to a very large degree. The supply of hot water presents particular problems with respect to the observance of microbiological parameters, since the hot water contains bacteria pathogenic for humans in the temperature scale of ideal conditions for multiplication (from 35 to 45 ° C in the case of legionella). Particularly critical are parts of the pipe system where the water sometimes remains for a relatively long time, such as the extraction points (water faucets, shower or sprinklers), since bio-films can occur There, they greatly promote the development of bacteria. Although all the above-mentioned pathogens lead to the detriment of health, they should be classified as particularly dangerous. Legionnaire's disease (legionellosis), caused by legionella, frequently leads to serious disqualifications (disability) and sometimes ends in death, and has been subject to a medical communication obligation in Germany since January 2001. The symptoms of Legionnaires' disease are very similar to those of a common lung inflammation, which minimizes the likelihood of successful treatment based on early detection, and possible only in the initial stage. Infection by IgGionelas occurs mainly by droplets of fine air (aerosols) that are breathed in, for example, in the shower or in sprinklers; but also by air droplets that occur, for example, in the points of extraction of the water, due to splashes. The most important conventional disinfection methods are: - thermal disinfection (thermal disinfection, on the one hand, is extremely costly and, on the other, the risk of burns at the temperature of hot water above 70 ° C) , at extraction points, it will be too high); - chemical disinfection or electrolytic disinfection with chlorine, hypochlorite or hypochlorous acid (chemical disinfection with chlorine, with hypochlorite or with hypochlorous acid is fundamentally risky when applied and sometimes leaves toxic residues, so that the quality of potable water demanded in the points of extraction would not be insured); and - radiation disinfection (for example, with ultraviolet (UV) light, ultrasound or microwave). Radiation disinfection can be carried out directly at the extraction points only with difficulty in practical terms and would also be too costly and would not allow continuous disinfection directly at the extraction points. None of these methods has been able, until now, to ensure the absence of pathogenic bacteria, in sufficient quantity, effectively, and at low maintenance costs. The most up-to-date publication on this was made in the German Federal Construction Document BBB 3-2005, in which four different sample systems for water disinfection were investigated in a long-term trial. The development of Legionella crops is particularly helped, in the case of high residence times in installed pipe systems. Cases of legionella infections, which occur repeatedly, particularly in public institutions (hospitals), show that the methods and safety systems that have been developed so far, and that are in use, do not always meet the requirements. For example, DE 44 1 6 501 A1 describes a yarn system with a multidimensional structure, formed from at least one yarn; having the yarn, in a humid environment, germicidal activity caused by oligodynamic metallic fractions of the yarn. This thread system, for example, in the form of a woven fabric formed of high quality silver steel wires, performs both the function of a mechanical sieve, and the function of a germicidal agent by the discharge of silver ions towards the water that flows through it. The wire system is normally fixed in the drinking water stream, transversely to the direction of flow, in order to effect the filter function. The silver ions discharged in this case are often not sufficient to kill germs located downstream, which are located, in particular, in colonies on bio-films. In addition, the cross-sectional area of the yarn system must be maintained through the cross-sectional area of the total flow. With the large number of different cross-sectional areas that occur in practice, it is necessary, in each case, that the thread system be cut to the proper size. Therefore, the objective on which the present invention is based is to provide a system of yarn to be installed in drinking water systems and other systems that conduct liquid, which guarantees high effectiveness with respect to the germs that occur in the bio -films; and that at the same time it can be used as universally as possible, and can be produced at a convenient cost. This objective is achieved by means of a yarn system having the aspects of claim 1. According to the invention, the yarn system is provided to have a first sheet-like structure, and a multiplicity of separate yarn elements, which extend transversely with respect to the sheet-like structure; in such a way that the yarn system forms a three-dimensional separating structure, elastically deformable; the yarn with the germicidal activity being arranged in the sheet-like structure and / or in the region of the yarn separating elements. The "transverse" aspect with respect to the sheet-like structure includes all the angular positions between the sheet-like structure and the wire-separating elements on the entire scale between 0 ° and 80 °. Furthermore, it is not necessary to say that thread separators do not necessarily run in a straight line, but can also be curved and interwoven. Additionally, it is important that the yarn separating elements run transversely, within the meaning of the above definition, only in portions, and if other portions are arranged in the plane of the sheet-like structure. On the other hand, it is conceivable that the sheet-like structures and the yarn separating elements are formed from one and the same yarn. This variant can be produced by a suitable continuous method. In the same way it is possible to produce the yarn separating elements from yarns other than the yarn forming the sheet-like structure. Therefore, within the scope of the invention, it is provided, on the one hand, the production of the yarn system only from yarn having germicidal activity or, on the other hand, the production of the yarn system as a combination of at least one thread with germicidal activity, with at least one thread that does not have germicidal activity. In this case, the respective threads are arranged in the sheet-like structure and / or in the region of the yarn separating elements that are adjacent to it.; or the sheet-like structure and / or the yarn separating elements are formed at least partially from the respective yarns. It is understood here that the yarn separating elements mean, in the simplest case, portions of yarn having the necessary elasticity so that the yarn system has the desired properties. Alternatively, it is also conceivable that the yarn separating element also forms a specific yarn separating system. That is, the yarn separating element itself is constructed as a knitted, woven, textured or interlaced knit, comprising at least one yarn. Of course, the yarn system according to the invention also comprises the design variants consisting of a plurality of yarns. The yarn separating elements, oriented transversely with respect to the yarn-like structure, form a three-dimensional separating structure of the yarn system. The aspect of elastic deformability should be understood here with the meaning that the yarn system has remarkable compressibility in relation to its dimensions in the transverse direction and, particularly, in a direction perpendicular to the sheet-like structure. After the deformation due to the action of force, the yarn system behaves, taking into account the material properties of the deformed yarn separating elements, largely to assume the non-deformed state again. The described elastic properties enable the use of one and the same wire system, in a multiplicity of different drinking water systems and other liquid conducting systems. A volumetric unit of the yarn system, which is larger than the spatial volume present in the mounting region of the drinking water system, is introduced and compressed in the assembly region. The yarn system can be expanded there and immobilized with the sheet-like structure and the separating yarn portions on the wall portions of the drinking water system delimiting the spatial volume. Thus, in particular, regions of stagnation, which are especially hazardous, in drinking water systems and other liquid conducting systems, can be provided along with the yarn system. In this case, it is advantageous in particular that the yarn system is pressed against the wall portions of the stagnation regions, taking into account their elastic properties. Thus, the yarn system is in direct contact by means of the sheet-like structure and / or its yarn separating elements, with the critical bio-films that occur particularly there. In addition, the yarn system according to the invention can be easily formed into different sizes. For this purpose, a plurality of yarn systems can be connected to each other to form a coupled yarn system. This is obtained, for example, by sewing, bonding with adhesive, welding or hooking the individual wire systems. The functionality of the coupled wire system will always correspond to that of the individual wire systems. It goes without saying that the entire wire system must have, in particular, the elastic properties required in the entire temperature range of the drinking water that occurs in drinking water systems and in other liquid conductor systems, from about 0. ° C up to 1 00 ° C. The materials are selected accordingly. Oligodynamic metals are known to people who have relevant experience in the field. These are semiprecious and precious metals, such as, for example, gold, silver and copper. However, zinc and nickel also have corresponding activity. The metal fractions, in this case, may be provided either in metallic form, as particles incorporated in the yarn structure, or as layers arranged on the yarn. Similarly, it is conceivable that metal fractions are provided in suitable ionic form, for example, as salts of said metals, in or on the wire. The germicidal oligodynamic activity of the yarn system is also measured by contact reaction of the bacteria on the surface of the yarn having the germicidal activity. That is, in addition to the action described above, metal ions released in water, metal atoms or metal ions that are not dissolved and are present on the surface of yarn, also contribute, when using low metal salts solubility in water, to the total oligodynamic effect of the yarn system introduced into a drinking water system. In order that the flow rate of drinking water is only slightly impeded, it is advantageous that the distance between the adjacent yarn separating elements of the yarn system, on average, is greater than 1 mm. Depending on the application, the "free" path length between the wire spacing elements can be made variable. The resistance to flow, of course, depends on the flow velocity, so that at very high flow rates, separations between yarn separating elements markedly greater than one millimeter are required. In terms of compressibility, the yarn separating elements are preferably designed in such a way that the yarn system can be compressed by at least 20 percent of its transverse extension, in a direction transverse to the first sheet-like structure. The amount of possible compression depends, on the one hand, on the restoring forces of the compressed spacer thread elements. However, on the other hand, excessive compression may also be undesirable in light of the rise in flow resistance of the compressed yarn system. The yarn-like structures are designed, in a manner known in the prior art, particularly with intertwining, knitting, knitted, or knitted fabric, or as fiber fluff elements. The sheet-like structure, due to its structure, makes it possible to detect a surface, with respect to which the separating thread elements extend transversely, and in this way, together with the sheet-like structure, form a three-dimensional separating structure, elastically deformable. Needless to say, the lamina-like structure has a purely two-dimensional design. This, in fact, would not be true, since a sheet-like textile structure, by virtue of its construction, should always have some extension transversely with respect to its extension area. It should be understood that an interlacing signifies a structure similar to a sheet that occurs due to the interweaving of intertwined thread systems, which run diagonally in opposite directions.; the intertwining yarns cross each other at an angle adjustable with respect to the edge of the fabric. It is understood that a contextu ra means a sheet-like structure consisting of one or more stretched yarn systems, which are laid on top of each other, of various directions of orientation, with or without fixation at the points on which they are placed. that cross each other A woven fabric is a sheet-like structure, in which the stitches are formed individually, and in succession, from a yarn presented horizontally. In addition, yarn systems can be additionally incorporated in the warp direction and / or in the weft direction, for reinforcement. It should be understood that the fiber fluff elements mean sheet-like structures, in which the sheetlike substrate is electrostatically charged, in order to permanently fix and fix fibers of a defined, uniform short length, or in a structure of systematic or random grid. The separating yarn elements can be woven, knitted fabrics, adhesively bonded or stitched together with the sheet-like structures mentioned above. In this case, the yarn separating elements may be in the form of a separate yarn or they may be designed as a yarn that is also arranged in the sheet-like structure. In a preferred embodiment of the yarn system, the yarn system has a second sheet-like structure, oriented essentially parallel to the first sheet-like structure; while the separating wire elements separate the first and the second sheet-like structures from each other. There are technologies in use for the production of fabrics and knit articles, by means of which the total spatial structure of a yarn system having two adjacent sheet-like structures can be efficiently produced in a single work process; for example, as a separate woven or knitted fabric. In this case, both a single wire and a combination of different wires can be used. It is within the scope of the invention that at least one thread must have the required germicidal activity. As noted above, the second sheet-like structure can be designed in a particular way, in particular, as an interlacing, a texture, a knitted or woven fabric, or a fiber fluff element. The coupling of the yarn separating elements to the second sheet-like structure can be implemented correspondingly to the coupling described above for the first sheet-like structure. In a variant to the yarn system, the complete yarn system of one and the same yarn is produced. However, this presupposes that the single yarn has the elastic properties necessary to separate the two sheet-like structures, and suitable germicidal activity. It is also conceivable that the two sheet-like structures are produced from an identical first thread, and the thread spacing elements, from a second thread. In this case, the first yarn and / or the second yarn with germicidal activity can be equipped. It applies to all variants of the yarn system that were described above, that at least one yarn or one of the yarns has a metallized, multifilament or monofilament textile yarn. Alternatively, or additionally, it is possible for a yarn or one of the yarns to be designed as a metallic yarn. Thin wires, preferably made of high quality steel, such as metal wires, are considered here; that is, a metallic wire consists entirely of metal. However, in the same way, it is conceivable to use a fiberglass, basalt or carbon fiber, with adequate properties in terms of elasticity or its germicidal activity. Additionally, it is advantageous to design the yarn system with fixing means for holding the yarn system in a drinking water system. Fixing means, within the context of this embodiment, are all systems, known from the prior art, which are suitable for fixing: immobilizers, adhesive bonding, latching, touch and lock fasteners, pins, screws, etc. Finally, it can be emphasized, with respect to the scope of the protection claimed, that a yarn system having the aspects of claim 1 is claimed, which is suitable for considerations related simply to the design, to install in drinking water systems and other liquid conducting systems, according to the definition given in the introduction to the description. A restriction of the scope of protection should not be assumed here because of the requirement of the appropriateness of the license from a legal point of view, in light of the many different national regulations for drinking water. Other advantages and aspects of the invention will be made clear in conjunction with the design variants, illustrated and described in the accompanying drawings, in which: Figure 1a shows a diagrammatic section, taken through a first embodiment of the yarn system, as a separating structure of two sheet-like structures, with straight wire spacing elements, oriented vertically. FIG. 1 b shows a sectional view of the mode according to FIG. 1 a, with the variant of having the yarn separating elements oriented obliquely. Figure 1 c shows a sectional view of the embodiment according to Figure 1 a, with the variant of having the yarn separating elements oriented obliquely in the crossed direction. Figure 1 d is a diagrammatic section, taken through a second embodiment of the yarn system, as a separating structure comprising a sheet-like structure and separating yarn elements, similar to stitches, oriented transversely with respect to the similar structure a sheet. Figure 1 e shows a sectional view of the embodiment according to Figure 1 d, with the variant of the bristle-like wire separator elements, arranged essentially perpendicular to the sheet-like structure. Figure 1 f shows a diagramatic cross-section, taken through a drinking water system in the form of a shower chive, with a thread system according to Figure 1 e, arranged therein. Figure 1 g shows a diagrammatic section taken through a shower chive with a thread system according to figure 1 e, arranged therein; the yarn system being attached to the chive of the shower by fixing means in the form of mechanical immobilizing devices; and Figure 2 shows a third embodiment of the yarn system, as a separating structure of two sheet-like structures, of modular construction. Figure 1 a shows a diagrammatic section, taken through a first embodiment of the yarn system 1, as a spacing structure of a first sheet-like structure 1 0 and of a second sheet-like structure 12. The first sheet-like structure 1 0 is illustrated diagrammatically in the form of a texture consisting of a multiplicity of fibers. The stitches shown of the second sheet-like structure 1 2 are to illustrate diagrammatically a second sheet-like structure 12, designed as a knitted fabric. In principle, in each case, knitted or woven fabrics and fabrics, in all their known variants of the prior art, can be contemplated to form the sheet-like structures 1 0, 1 2. In order to simplify the diagrammatic illustrations, the sheet-like structures 1 0, 1 2 of the variants and the embodiments in the remaining figures are illustrated merely in diagrammatic form, without the details of the wires disposed therein. The two sheet-like structures 1 0, 12 are spaced apart by the spacer thread elements 1 1. These, in this variant of the yarn system 1, extend at right angles to the extension plane of the two sheet-like structures 10, 12. The first sheet-like structure 1 0 is illustrated diagrammatically in the form of a texture consisting of a multiplicity of fibers. The stitches shown of the second sheet-like structure 12 are to illustrate diagonally a second sheet-like structure 12, designed as a knitted fabric. In principle, in each case, the knitted or woven fabrics and fabrics, in all their variants of the prior art, can be contemplated to form the sheet-like structures 1 0, 1 2. In order to simplify the diagrammatic illustrations, the lamellar-like structures 1, 12 are illustrated, the variants and the modalities in the remaining figures are illustrated merely in diagrammatic form, without the details of the threads disposed therein. The two sheet-like structures 1, 12 are spaced apart by means of wire separators 1 1. These, in this variant of the yarn system 1, extend at right angles with respect to the extension plane of the two sheet-like structures 1, 12. It goes without saying that at least the material properties of the yarn separating elements 1 1 must be such that a shear stress or compression of the separating structure is possible. In this case, the yarn separators 1 1 are folded essentially parallel to each other, to the right or to the left, or the yarn separators 1 1, originally stretched, are brought to a curved shape by deformation. In this case, the first sheet-like structure 1 0 approaches the second sheet-like structure 1 2. The deformation energy is ideally stored completely as potential energy of the folded wire separators 1 1 in the separating structure, and can be recovered from the new one. Of course, a multiplicity of other angular positions, not shown here, between 0o and 1 80 °, with respect to the arrangement of the yarn separating elements and the sheet-like structures, is possible. The multidimensional structure of the yarn system 1 is formed of a multiplicity of yarns. At least one is provided as a thread 200, with germicidal activity. In the variant of the yarn system, as shown in FIG. 1 a, the thread 200 with germicidal activity is arranged in the region of the yarn separators 1 1. On one side, this can be implemented in such a way that the germicidal thread 200, in addition to its oligodynamic activity, assumes at the same time the function of a thread separating element. It is also possible for the germicidal thread 200 to be arranged adjacent to a yarn separating element 1, which has the desired elastic properties for the separating structure. This arrangement can be implemented, spaced, or the thread separator element 1 and the germicidal thread 200 are processed together in the form of a thread or a twine. Of course, it is also possible, alternatively or additionally, to arrange the yarns with germicidal properties in the region of the sheet-like structures 1 0, 1 2. These variants are described in conjunction with the following figures. It is understood that the geometric orientation of the yarn separating elements 1 can have a multiplicity of different variants, Figs. 1 b and 1 c illustrate two additional variants in a sectional view, corresponding to Fig. 1 a. Figure 1 b shows an arrangement in which the elements 1 1 thread separators run between the first sheet-like structure 1 0 and the second sheet-like structure 1 2, different from a perpendicular orientation, slightly oblique at an angle greater than 80 °. Here, the germicidal thread 200 is provided only in the two sheet-like structures 1, 12.

Furthermore, it is conceivable that the spacer thread elements 1 1 are curved, as shown in FIG. 1 c, crossed with respect to each other. It is essential, in each case, that only the desired elasticity of the yarn system 1 be implemented, taking into account the weight force of the sheet-like structures 1, 12, and the material properties of the separator elements 1 1. thread. Furthermore, the orientation of the wire separator elements 1 1, between the first sheet-like structure 1 0 and the second sheet-like structure 12, depends on how the connection between the sheet-like structures and the elements 1 1 has been made. thread separators. This can take place, in particular, by knotting, by adhesive bonding, welding, knitting or hooking. Figure 1 d shows a second embodiment of the yarn system. A single structure 1 0 similar to a sheet is provided, for whose formation the signals made in relation to Figure 1 a apply correspondingly. The wire separator elements 1 1, in a stitch-like manner, run transversely, in this case perpendicularly or virtually perpendicularly, with respect to the plane or extension of the sheet-like structure 1 0. These stitches have the corresponding elastic properties, so that the three-dimensional separating structure can be compressed as a result of the deformation of the seams.

The same applies correspondingly to the variant shown in Figure 1 e, of the second embodiment of the yarn system. In contrast to the first variant of Figure 1 d, the yarn separator elements 1 1 are provided in the form of individual stretched yarn portions. These portions of yarn run essentially perpendicular to the plane of extension of the sheet-like structure 1 0, so that the yarn system 1 has a brush-like design. For both variants of the second embodiment of the thread system, it is applicable, correspondingly, what is indicated in relation to figure 1 a, that the germicidal thread 200 can be provided in the structure 1 0 similar to sheet and / or in the region of the elements 1 1 thread separators. The other indications related to the arrangement and processing of the germicidal thread 200, together with the illustrations of FIGS. 1 a to 1 c, are correspondingly applied here. As an application of the yarn system to Figure 1 e, which should be understood purely as an example, the cross section of a drinking water system T, in the form of a shower chive is illustrated diagrammatically in Figures 1 f and 1 g. You can see how the thread system 1 is arranged inside the shower chive. The cavity of the shower chive extending between the walls T1 and the water outlet plate T2 has elements 1 1 thread separators of a system 1 of yarn passing therethrough. The sheet-like structure 1 0 of the yarn system 1, in this case, remains on the water outlet plate T2 and has a correspondingly stout design, in order to resist sufficient resistance to low flow to the passing water. through it. The distance between the plane of the sheet-like structure 1 0 and the opposite wall T1 is less than the length of the individual wire-separating elements. As a result, the yarn system 1 can be introduced into the shower chive only under certain compression of the yarn separating elements 1 1. This ensures that the elastically deformed yarn separating elements 1 1 press against the wall T1 of the shower chive. Since the elements 1 1 shower dividers are equipped with a germicidal thread 200, this ensures the microbicidal interaction between the yarn system and a bio-film that is formed, in particular, on the wall T1. If the three-dimensional volume of the compressed wire system 1 is not sufficient to fill a cavity of a drinking water system T, through which water flows, or if the fixing of the yarn system 1 is to be ensured in this cavity, then It can be secured by fixing means. These fastening means may be designed, for example, as shown in Figure 1 g, in the form of mechanical moving devices 1 3. As shown by way of example, these are designed as compression springs which ensure the desired adjustment of the yarn system 1 in the drinking water system T. The separating yarn elements 1 1 of the modalities described up to and including their variants, in the simplest case, can be designed as portions of a yarn It consists of a strand or twine, which has the required elastic properties. However, it is also conceivable to design the wire separators 1 1, themselves, as specific hyl separator systems. They can be provided as woven, knitted, textured or interlaced elements with one or more threads, and conform in their construction, for example, to the variants shown in FIGS. 1 a to 1 e. Said exemplary embodiment is illustrated diagrammatically in Figure 2, as a third embodiment of the yarn system 1. The first sheet-like structure 1 and the second sheet-like structure 1 2 are spaced apart from each other, in this case, by means of 1 1 thread separators that run in a trapezoidal manner and in the shape of the system. thread separator mentioned above. The connection or connection of the yarn separating systems with the two sheet-like structures 1 0, 12 takes place here by means of separate stitches, by means of a sewing thread 1 1 0. Alternatively to the sewing stitches, it can be It is also possible to contemplate bonding with adhesive or welding For any of the variants described above, the germicidal yarn may be arranged in the sheet-like structures and / or in the region of the yarn separating elements. For this purpose, it is possible for the germicidal yarn to be at least partially integral to the structure in the sheet-like structure and / or in the yarn separating elements. For that purpose, the germicidal thread may be in the form of a strand or a twine, having the necessary mechanical and elastic properties for the respective structure. Similarly, it is conceivable that the germicidal yarn is incorporated in the sheet-like structure and / or in the yarn separating elements, as a yarn structure independent of the structures in the sheet-like structure and in the yarn separating elements. . Of course, the object of the present invention also comprises mixed forms of the variants mentioned hereinabove.

A volumetric unit of the yarn system (1), which is larger than the spatial volume of the assembly region of the drinking water system, is introduced into the assembly region, in a compressed manner. Then the yarn system (1) is allowed to expand and stick with the surface structure (10) and the fibrous spacer sections (11) to the wall sections of the drinking water system (1) that define the spatial volume.
