Description

Die Erfindung betrifft ein textiles Flächengebilde nach dem Oberbegriff von Anspruch 1.The invention relates to a textile fabric according to the preamble of claim 1.

Textile Flächengebilde, insbesondere Flachgestricke, werden zu unterschiedlichsten Anwendungen herangezogen. Insbesondere im Kleidungsbereich aber auch bei Funktionstextilien kommen sie zum Einsatz. Eine Anwendungsmöglichkeit im medizinischtherapeutischen Bereich, sind beispielsweise Kompressionsstrümpfe oder Bandagen, mit denen Körperbereiche stützend umgeben werden. Hierbei finden insbesondere elastisch streckbare textile Flächengebilde Anwendung. Mit modernen Wirk- oder Strickverfahren ist es möglich, derartige textile Flächengebilde speziell an die Körperpartie anzupassen, bei der sie zum Einsatz kommen sollen. So kann beispielsweise bei einer Kniebandage der Bereich, der in Anlage mit der Kniescheibe kommt, hinsichtlich Elastizität, Materialstärke, Lüftungsverhalten etc. andersartig ausgebildet werden, als der Bereich, der mit der Kniekehle in Anlage kommt, oder der Bereich, der am Ober- bzw. Unterschenkel anliegt. Eine derartige bereichsspezifische Ausbildung einer Bandage macht aber nur dann Sinn, wenn gewährleistet ist, dass die Bandage dauerhaft am Patienten richtig positioniert ist. Sollte die Bandage verrutschen, verringert sich der Tragekomfort wesentlich.Textile fabrics, especially flat knits, are used for a wide variety of applications. Especially in the clothing sector but also in functional textiles they are used. One possible application in the field of medical therapy, for example, compression stockings or bandages, with which body areas are surrounded supporting. In particular elastically stretchable textile fabrics are used here. With modern knitting or knitting methods, it is possible to adapt such textile fabrics specifically to the body part in which they are to be used. For example, in the case of a knee bandage, the area that comes into contact with the kneecap may be formed differently in terms of elasticity, material thickness, ventilation behavior, etc. than the area that comes into contact with the popliteal fossa, or the area that is at the upper or Lower leg is present. However, such a region-specific design of a bandage makes sense only if it is ensured that the bandage is permanently positioned correctly on the patient. If the bandage slips, the wearing comfort is reduced significantly.

Aus diesem Grund ist es zwischenzeitlich üblich, rutschhemmende Beschichtungen auf derjenigen Oberfläche anzubringen, die auf der Haut des Patienten zur Anlage kommt. Hierfür werden beispielsweise Gummierungen oder eine Beschichtung mit Silikonpunkten oder -wellen nachträglich auf das textile Flächengebilde aufgetragen. Häufig werden auch Silikonhaftbänder nachträglich aufgenäht. Zwar hat diese Maßnahme den Effekt, dass tatsächlich ein Verrutschen der Bandage zeitweise verhindert werden kann. Sie bringt aber andere Nachteile mit sich, wie erhöhte Schweißbildung im Bereich der Gummierung, was den Tragekomfort ebenfalls beeinträchtigt und auf Dauer die rutschhemmende Wirkung reduziert. Zusätzlich angenähte Silikonhaftränder führen zu Druckstellen und Einschnürungen, da ihr Elastizitätsverhalten selten dem des Bandagengestricks entspricht.For this reason, it has become customary in the meantime to apply anti-slip coatings on the surface that comes to rest on the skin of the patient. For this example, rubber coatings or a coating with silicone dots or waves are subsequently applied to the textile fabric. Frequently, silicone adhesive tapes are also sewn on later. Although this measure has the effect that actually a slipping of the bandage can be temporarily prevented. However, it brings with it other disadvantages, such as increased perspiration in the area of the rubber coating, which also impairs the wearing comfort and permanently reduces the anti-slip effect. Additional sewn-on silicone adhesive edges lead to pressure points and constrictions, since their elasticity behavior rarely corresponds to that of the bandage knit.

Das nachveröffentlichte Dokument WO 2014/098928 A1 offenbart eine medizinische Kompressionsbandage mit einem rundgestrickten schlauchförmigen Körper, wobei ein rutschhemmender Bereich an einer inneren Oberfläche vorgesehen ist, um mit der Haut eines Patienten in Anlage zu gelangen. Der rutschhemmende Bereich umfasst Garne mit hohen und niedrigen Reibungskoeffizienten, wobei die Garne mit hohem Reibungskoeffizient erhöhte Oberflächenabschnitte des rutschhemmenden Bereiches bilden.The post-published document WO 2014/098928 A1 discloses a medical compression bandage having a circular knit tubular body wherein a slip resistant area is provided on an interior surface for engaging the skin of a patient. The non-slip area includes Yarns having high and low coefficients of friction, wherein the high coefficient of friction yarns form increased surface portions of the slip resistant region.

Das Dokument US 6 871 516 B2 offenbart eine rundgestrickte medizinische Kompressionsbandage mit einem integral eingestrickten rutschhemmenden Bereich, der je nach vorgesehenem Anwendungsfall verschiedenartig innerhalb der Bandage positioniert ist.The document US Pat. No. 6,871,516 B2 discloses a circular-knit medical compression bandage having an integrally-knit slip-resistant area which is variously positioned within the bandage depending on the intended application.

Das Dokument WO 03/008685 A1 offenbart als nächstkommender Stand der Technik ein Verfahren zum Herstellen von rundgestrickten Strumpfwaren, bei dem ein oberer Bund durch Verstricken eines Elastomerfadens ausgebildet wird, der in einem der Haut des Patienten zugewandten Bereich teilweise exponiert ist.The document WO 03/008685 A1 discloses, as the closest prior art, a method for making circular knit hosiery in which an upper waistband is formed by entangling an elastomeric thread partially exposed in an area facing the skin of the patient.

Das Dokument US 2013/295812 A1 offenbart ein Strickmaterial, bei dem zwei gegenüberliegende Schichten eines Jersey-Strickmaterials miteinander vernäht werden. Die ersten und zweiten Schichten umfassen jeweils Gummifäden.The document US 2013/295812 A1 discloses a knit material in which two opposing layers of jersey knit material are sewn together. The first and second layers each comprise rubber threads.

Das Dokument US 2012/0324961 A1 offenbart eine rundgestrickte Strickware mit einem Bundbereich, der eine Anti-Rutsch-Zone aufweist, die durch Verstricken mehrerer rutschhemmender Fäden hergestellt wird.The document US 2012/0324961 A1 discloses a circular knit fabric having a waistband region having an anti-slip zone made by entangling a plurality of slip resistant yarns.

Es ist daher Aufgabe der vorliegenden Erfindung, ein textiles Flächengebilde bereitzustellen, dass zumindest abschnittsweise eine rutschhemmende Wirkung unter Vermeidung der vorstehenden Nachteile herkömmlicher Lösungen vorsieht.It is therefore an object of the present invention to provide a textile fabric that at least partially provides a slip-resistant effect while avoiding the above disadvantages of conventional solutions.

Diese Aufgabe wird durch ein textiles Flächengebilde mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a textile fabric having the features of claim 1.

Die Erfindung sieht also zunächst vor, dass bei der Herstellung des textilen Flächengebildes als ein Fadensystem ein Silikonfaden verwendet wird. Derartige Silikonfäden sind seit kurzem beispielsweise von der Firma Massebeuf Textiles® verfügbar. Sie zeichnen sich dadurch aus, dass sie vollständig mit Silikon beschichtet sind. Das Material hat einen Fadenkern aus Polyamid 35% und einen Mantel aus Silikon 65%. Es gibt auch Silikonfäden, die zu 100% aus Silikon bestehen. Diese haben eine hohe Elastizität und sind daher schwerer zu verarbeiten. Daher wird die Variante mit unelastischem Fadenkern bevorzugt. Die Erfindung sieht vor, einen derartigen Silikonfaden im Rahmen eines textilen Flächengebildes zu verarbeiten.Thus, the invention initially provides that a silicone thread is used as a thread system in the production of the textile fabric. Such silicone threads have recently become available, for example, from Massebeuf Textiles®. They are characterized by the fact that they are completely coated with silicone. The material has a thread core of polyamide 35% and a jacket of silicone 65%. There are also silicone threads made of 100% silicone. These have a high elasticity and are therefore harder to process. Therefore, the variant with inelastic thread core is preferred. The invention provides to process such a silicone thread in the context of a textile fabric.

Es hat sich aber gezeigt, dass der Silikonfaden an der mit der Haut eines Patienten in Kontakt tretenden ersten Oberfläche des textilen Flächengebildes nicht allzu exponiert und flächig verlaufen darf. Andernfalls würde der Silikonfaden, der keine Flüssigkeit aufnehmen kann, zu verstärkter Schweißbildung führen. Aus diesem Grund sieht die Erfindung vor, dass der hydrophobe Silikonfaden an der ersten Oberfläche des textilen Flächengebildes zwar in Kontakt mit der Haut eines Patienten kommen soll, um die rutschhemmende Wirkung zu gewährleisten, dieser Kontakt aber nur in eingeschränktem Umfang erfolgen sollte. Dies kann dadurch erreicht werden, dass die Maschen aus dem Silikonfaden derart in dem textilen Flächengebilde verlaufen, dass nur deren Maschenschenkel abschnittsweise auf der ersten Oberfläche exponiert sind und in Kontakt mit der Haut des Patienten treten. Die Maschenköpfe hingegen sind in das textile Flächengebilde derart eingebunden, dass sie von der ersten Oberfläche abgewandt sind. Dadurch lässt sich einerseits eine rutschhemmende Wirkung erreichen, andererseits eine zu starke Exposition des Silikonfadens an der mit der Haut des Patienten in Kontakt tretenden ersten Oberfläche unterbinden.It has been found, however, that the silicone thread may not be exposed on the first surface of the textile fabric which comes into contact with the skin of a patient, and may not extend over a wide area. Otherwise, the silicone thread, which can not absorb liquid, would lead to increased perspiration. For this reason, the invention provides that the hydrophobic silicone thread on the first surface of the textile fabric, although it should come into contact with the skin of a patient, to ensure the anti-slip effect, but this contact should be made only to a limited extent. This can be achieved in that the stitches of the silicone thread run in such a way in the textile fabric that only the mesh legs are exposed in sections on the first surface and come into contact with the skin of the patient. By contrast, the mesh heads are integrated into the textile fabric in such a way that they are remote from the first surface. On the one hand, this makes it possible to achieve an anti-slip effect and, on the other hand, to prevent excessive exposure of the silicone filament to the first surface which comes into contact with the patient's skin.

Eine Weiterbildung der Erfindung sieht vor, dass zwei zueinander gehörende Maschenschenkel der Masche, die mit dem Silikonfaden des zweiten Fadensystems im Bereich der ersten Oberfläche gebildet ist, im Wesentlichen V-förmig zueinander verlaufen. Dieses Merkmal der Erfindung erhöht die rutschhemmende Wirkung des in das textile Flächengebilde eingebunden Silikonfadens. Die beiden nicht parallel zueinander sondern geneigt zueinander, im Wesentlichen V-förmig geneigt zueinander, verlaufenden Maschenschenkel wirken nicht nur wegen der materialbedingt rutschhemmenden Wirkung des Silikonfadens, sondern auch aufgrund ihres Verlaufs rutschhemmend.A further development of the invention provides that two mutually belonging mesh legs of the mesh, which is formed with the silicone thread of the second thread system in the region of the first surface, extend substantially V-shaped relative to one another. This feature of the invention enhances the anti-slip effect of the silicone thread incorporated into the fabric. The two not parallel to each other but inclined to each other, substantially V-shaped inclined to each other, extending mesh legs act not only because of the material-related slip-resistant effect of the silicone yarn, but also slip-resistant due to their course.

Eine Weiterbildung der Erfindung sieht vor, dass das zweite Fadensystem im textilen Flächengebilde an der ersten Oberfläche als Fangbindung eingelegt ist. Dadurch kann erreicht werden, dass keine Maschenköpfe des Silikonfadens des zweiten Fadensystems an der Oberfläche des textilen Flächengebildes exponiert sind.A development of the invention provides that the second thread system is inserted in the fabric on the first surface as a capture bond. It can thereby be achieved that no mesh heads of the silicone thread of the second thread system are exposed on the surface of the textile fabric.

Eine Weiterbildung der Erfindung kann ferner vorsehen, dass der Silikonfaden des zweiten Fadensystems nur bereichsweise in das textile Flächengebilde eingebunden ist. Dies bedeutet, dass der den Tragekomfort aufgrund seiner mangelnden Feuchtigkeitsaufnahmefähigkeit beeinträchtigende Silikonfaden in das textile Flächengebilde nur dort eingebunden wird, wo tatsächlich eine rutschhemmende Wirkung erforderlich ist. In solchen Bereichen des textilen Flächengebildes, in denen keine rutschhemmende Wirkung benötigt wird, wird das textile Flächengebilde ohne Einbindung des Silikonfadens hergestellt. In diesem Zusammenhang kann gemäß einer Ausführungsform der Erfindung vorgesehen sein, dass der Silikonfaden des zweiten Fadensystems in schmalen Streifen in das textile Flächengebilde eingebunden ist. Alternativ zu Streifen sind auch andere Geometrien der Bereiche möglich, in dem der Silikonfaden eingebunden ist, wie beispielsweise punktuelle Bereiche, geschlossene Formen, wie Kreise, Ringe, Wellen oder dergleichen.A development of the invention may further provide that the silicone thread of the second thread system is only partially integrated into the textile fabric. This means that the silicone yarn, which impairs the wearing comfort due to its lack of moisture absorption capacity, is only incorporated into the textile fabric where a slip-resistant effect is actually required. In those areas of the textile fabric in which no slip-resistant Effect is needed, the fabric is produced without the involvement of the silicone thread. In this context, according to one embodiment of the invention, provision may be made for the silicone thread of the second thread system to be bound in narrow strips in the textile fabric. As an alternative to strips, other geometries of the regions in which the silicone thread is incorporated, such as punctiform regions, closed shapes such as circles, rings, waves or the like, are also possible.

Eine Weiterbildung der Erfindung sieht vor, dass der Silikonfaden des zweiten Fadensystems mit einem Strickgarn eines dritten Fadensystems abgebunden ist. Als Strickgarn zum Abbinden wird herkömmliches Material verwendet, wie beispielsweise ein Garn aus Nylon oder Baumwolle. Dadurch ist es möglich, die Größe der Maschen und das Maschenbild aktiv zu beeinflussen. Es ist nämlich festzustellen, dass Silikonfäden im Rahmen von herkömmlichen Strickverfahren oder Wirkverfahren nur schwer verarbeitbar sind. Das Abbinden mit einem herkömmlichen Garn erleichtert die Verarbeitung.A development of the invention provides that the silicone thread of the second thread system is tied with a knitting yarn of a third thread system. As a knitting yarn for setting, conventional material is used, such as a yarn of nylon or cotton. This makes it possible to actively influence the size of the stitches and the stitch pattern. It can be stated that silicone threads are difficult to process in the context of conventional knitting methods or knitting methods. Bonding with a conventional yarn facilitates processing.

Gemäß einer Ausführungsform der Erfindung kann vorgesehen sein, dass es das erste Fadensystem mit einem Strickfaden, das zweite Fadensystem mit dem Silikonfaden, das dritte Fadensystem mit einem weiteren Strickfaden sowie wenigstens einen Schussfaden aufweist.According to one embodiment of the invention, it can be provided that it has the first thread system with a knitting thread, the second thread system with the silicone thread, the third thread system with a further knitting thread and at least one weft thread.

Die Erfindung betrifft ferner ein Verfahren zum Herstellen eines textilen Flächengebildes nach einem der vorangehenden Ansprüche, wobei das textile Flächengebilde aus wenigstens zwei Fadensystemen hergestellt ist, die durch Ausbildung von Maschen mit einem Maschenkopf und zwei zu dem Maschenkopf führenden Maschenschenkeln miteinander verbunden sind, umfassend eine erste Oberfläche und eine von der ersten Oberfläche abgewandte zweite Oberfläche, wobei ein erstes Fadensystem mit einem Garn hergestellt wird und wobei ein zweites Fadensystem mit einem Silikonfaden hergestellt wird, wobei das textile Flächengebilde derart ausgebildet wird, dass der Silikonfaden des zweiten Fadensystems an der ersten Oberfläche im Wesentlichen nur im Bereich seiner Maschenschenkel exponiert ist.The invention further relates to a method of producing a fabric according to any one of the preceding claims, wherein the fabric is made of at least two thread systems joined together by forming stitches with a stitch head and two stitch loops leading to the stitch head, comprising a first one Surface and a second surface facing away from the first surface, wherein a first thread system is made with a yarn and wherein a second thread system is made with a silicone thread, wherein the fabric is formed such that the silicone thread of the second thread system at the first surface in the Essentially exposed only in the area of its mesh legs.

Die Erfindung wird im Folgenden beispielhaft anhand der folgenden Figuren erläutert. Es stellen dar:

In Figur 1 ist ein erfindungsgemäßes textiles Flächengebilde schematisch dargestellt und allgemein mit 10 bezeichnet. Dieses umfasst eine erste in der Darstellung obere Oberfläche 12 sowie eine zweite in der Darstellung untere Oberfläche 14. Das gezeigte Flächengebilde 10 ist Teil einer medizinischen Bandage. Es kommt mit der ersten Oberfläche 12 in Kontakt mit der Haut eines Patienten und soll auf dieser nicht verrutschen.In FIG. 1 an inventive textile fabric is shown schematically and generally designated 10. This includes a first upper surface 12 as shown and a second lower surface 14 in the illustration. The fabric 10 shown is part of a medical bandage. It comes with the first surface 12 in contact with the skin of a patient and should not slip on this.

Man erkennt in Figur 1, dass das Flächengebilde 10 drei Streifen 16, 18, 20 aufweist. In diesen Bereichen 16, 18, 20 ist das textile Flächengebilde 10 rutschhemmend ausgebildet. Ferner weist es Bereiche 22, 24, 26, 28 auf, in denen es nicht rutschhemmend ausgebildet ist. Die Rutschhemmung wird bei dem erfindungsgemäßen textilen Flächengebilde 10 durch Einbinden eines Silikonfadens einerseits und durch einen bestimmten Fadenverlauf andererseits erreicht. Hierauf wird im Folgenden eingegangen. Beim Gebrauch der Bandage wird die rutschhemmende Wirkung des Silikonfadengestricks 10 noch verstärkt, indem die Bandage sich mit ihrem Kompressionsdruck an das Bein "krallt".One recognizes in FIG. 1 in that the sheet 10 has three strips 16, 18, 20. In these areas 16, 18, 20, the textile fabric 10 is formed slip-resistant. Furthermore, it has areas 22, 24, 26, 28, in which it is not designed to be slip-resistant. The slip resistance is achieved in the textile fabric 10 according to the invention by incorporating a silicone thread on the one hand and by a specific thread course on the other. This will be discussed below. When using the bandage, the anti-slip effect of the silicone thread mesh 10 is further enhanced by the bandage "clawing" with its compression pressure on the leg.

Figur 2 zeigt zur Erläuterung zwei Maschen 30, 32 eines herkömmlichen Gestricks in vergrößerter Darstellung. Man erkennt dass ein Maschenkopf 34 der Masche 32 den Maschenfuß 36 der Masche 30 umschlingt. Ferner erkennt man, dass die Maschenschenkel 38, 40 der Masche 32 nicht zu einander parallel laufen, sondern im Wesentlichen V-förmig zueinander geneigt sind. FIG. 2 for explanation, two stitches 30, 32 of a conventional knitted fabric in an enlarged view. It can be seen that a mesh head 34 of the stitch 32 wraps around the stitch foot 36 of the stitch 30. Furthermore, it can be seen that the mesh legs 38, 40 of the mesh 32 do not run parallel to each other, but are substantially V-shaped inclined to each other.

Figuren 3a bis 3c zeigen im Hinblick auf die schematische Darstellung gemäß Figur 1 die einzelnen Fadensystemen zur Herstellung der Bereiche 16, 18, 20 mit eingebundenem Silikonfaden, wobei sich in den Figuren jeweils unten die erste Oberfläche 12 und oben die zweite Oberfläche 14 ausbildet. Figur 3a zeigt in durchgezogener Linie das Fadensystem eines ersten Strickfadens 42, beispielsweise aus dem Material Polyamid 6.6 (Nylon) oder einem Polyamid- /Polyester-Mischgarn. Es kann aber auch jegliches Baumwolle-Mischgarn sein. Der erste Strickfaden 42ist über einzelne Nadeln 44 einer herkömmlichen Strickmaschine geführt. FIGS. 3a to 3c show with regard to the schematic representation according to FIG FIG. 1 the individual thread systems for the production of the areas 16, 18, 20 with integrated Silicone thread, wherein in the figures in each case below the first surface 12 and above the second surface 14 is formed. FIG. 3a shows in a solid line the thread system of a first knitting yarn 42, for example made of the material polyamide 6.6 (nylon) or a polyamide / polyester blended yarn. But it can also be any cotton blended yarn. The first knitting yarn 42 is passed over individual needles 44 of a conventional knitting machine.

Figur 3b zeigt in Strichlinie das Fadensystem eines Silikonfadens 46. Man erkennt, dass der mit Strichlinien eingezeichnete Silikonfaden 46 auf der ersten Oberfläche 12 (in Figur 3b unten) nur als Fangbindung eingelegt ist. Er bildet an der ersten Oberfläche 12 keine volle Masche aus. FIG. 3b shows in phantom the thread system of a silicone thread 46. It can be seen that the drawn with dashed lines silicone thread 46 on the first surface 12 (in FIG. 3b below) is inserted only as a capture bond. It does not form a full mesh on the first surface 12.

Figur 3c zeigt das dritte Fadensystem eines zweiten Strickfadens 48, beispielsweise aus dem Material Polyamid 6.6 (Nylon) oder einem Polyamid-/Polyester-Mischgarn. Es kann aber auch jegliches Baumwolle-Mischgarn sein. Der zweite Strickfaden 48 dient dazu, den Silikonfaden 46 abzubinden. Figure 3c shows the third thread system of a second knitting thread 48, for example made of the material polyamide 6.6 (nylon) or a polyamide / polyester blended yarn. But it can also be any cotton blended yarn. The second knitting thread 48 serves to bind the silicone thread 46.

Figur 3d zeigt das Gesamtsystem mit allen drei Fadensystemen 42, 46, 48. 3d figure shows the overall system with all three thread systems 42, 46, 48.

Figuren 4a bis 4d zeigen im Hinblick auf die schematische Darstellung gemäß Figur 1 die einzelnen Fadensysteme zur Herstellung der Bereiche 24, 26, 28 ohne eingebundenen Silikonfaden 46. Die Fadenverläufe des ersten Strickfadens 42 und des zweiten Strickfadens 48 sind identisch, wie in den Figuren 3a und 3c. Figur 4d zeigt wiederum das Gesamtsystem mit den Fadensystemen 42, 48. FIGS. 4a to 4d show with regard to the schematic representation according to FIG FIG. 1 the individual thread systems for producing the regions 24, 26, 28 without integrated silicone thread 46. The yarn courses of the first knitting yarn 42 and the second knitting yarn 48 are identical, as in FIGS FIGS. 3a and 3c , FIG. 4d again shows the overall system with the thread systems 42, 48.

Durch diese Fadenverläufe lässt sich das textile Flächengebilde 10 in Form eines Gestricks herstellen, das in den Bereichen 22, 24, 26, 28 ohne Silikonfaden in üblicher Weise ausgebildet ist, beispielsweise elastisch zum Erzielen eines Kompressionseffekts mit guten Flüssigkeitsaufnahme- bzw. Flüssigkeitsabtransporteigenschaften von der Haut eines Patienten. In den Bereichen 16, 18 und 20 ist das textile Flächengebilde 10 jedoch rutschhemmend ausgebildet, weil in diesen Bereichen der Silikonfaden 46 eingebunden ist. Die Einbindung erfolgt, wie in Fig. 3a bis 3d dargestellt, jedoch in einer Weise, dass nur kurze Abschnitte, nämlich Abschnitte der Maschenschenkel 38, 40 auf der ersten Oberfläche 12 exponiert sind und so in Kontakt mit der Haut eines Patienten gelangen. Diese kurzen Abschnitte der Silikonfäden 46 sorgen für eine hinreichende rutschhemmende Wirkung aufgrund der Materialeigenschaften des Silikons und aufgrund der nicht-parallelen Verläufe der Maschenschenkel. Andererseits sind diese mit der Haut des Patienten in Kontakt tretenden Abschnitte der Silikonfäden 46 kurz genug, um erhöhte Schweißbildung oder Ablagerungen von Hautschuppen in den Bereichen 16, 18, 20 zu vermeiden.As a result of these thread courses, the textile fabric 10 can be produced in the form of a knit fabric which is formed in the usual manner in the regions 22, 24, 26, 28, for example elastically for achieving a compression effect with good liquid absorption or liquid removal properties from the skin a patient. In the areas 16, 18 and 20, however, the textile fabric 10 is designed to be slip-resistant, because in these areas the silicone yarn 46 is integrated. The integration takes place as in Fig. 3a to 3d but in a manner that only short portions, namely portions of the mesh legs 38, 40 are exposed on the first surface 12 and thus come into contact with the skin of a patient. These short portions of the silicone filaments 46 provide a sufficient slip-resistant effect due to the material properties of the silicone and due to the non-parallel courses of the mesh legs. On the other hand, these are in contact with the skin of the patient Sections of the silicone filaments 46 are short enough to avoid increased perspiration or deposits of dander in the areas 16, 18, 20.

Mit der Erfindung lässt sich einerseits eine hervorragende rutschhemmende Wirkung erzielen, andererseits die bei herkömmlichen Gummierungen damit einhergehenden Nachteile, insbesondere die erhöhte Schweißbildung unterbinden.On the one hand, the invention makes it possible to achieve an outstanding anti-slip effect, on the other hand, it prevents the disadvantages associated with conventional rubber coatings, in particular the increased formation of perspiration.
