Description

Die vorliegende Erfindung betrifft einen Garniturträger für flexible oder halbstarre Garnituren.
Flexible und halbstarre Garnituren werden in verschiedenen Bereichen der Verarbeitung von textilen Fasern eingesetzt. Eine flexible oder halbstarre Garnitur besteht im Wesentlichen aus einem Garniturträger und den Garniturspitzen. Die Garniturspitzen werden durch Drahthäkchen gebildet, welche U-förmig ausgebildet sind. Die Drahthäkchen werden in einem sogenannten Setzvorgang in bestimmten Abständen und Anordnungen durch den Garniturträger hindurch gestochen, wobei deren Enden aus dem Garniturträger hervorstehen und die Garniturspitzen bilden. Die Anzahl Garniturspitzen pro Flächeneinheit wird als Spitzendichte bezeichnet. Die Drahthäkchen werden im Garniturträger gehalten und weisen abhängig von ihrer Form und Länge sowie der Beschaffenheit des Garniturträgers eine gewisse Flexibilität auf. Halbstarre Garnituren weisen die stärkeren Drahthäkchen auf als die flexiblen Garnituren. Ebenfalls ist der Garniturträger bei halbstarren Garnituren stärker, im Sinne von geringerer Flexibilität, als bei flexiblen Garnituren ausgeführt.The present invention relates to a clothing carrier for flexible or semi-rigid trimmings.
Flexible and semi-rigid trimmings are used in various areas of textile fiber processing. A flexible or semi-rigid set consists essentially of a clothing carrier and the clothing tips. The clothing tips are formed by wire hooks which are U-shaped. The wire tokens are pierced in a so-called setting process at certain intervals and arrangements through the clothing carrier, the ends of which protrude from the clothing carrier and form the clothing tips. The number of clothing tips per unit area is referred to as peak density. The wire tokens are held in the clothing carrier and have a certain flexibility, depending on their shape and length and the nature of the clothing carrier. Semi-rigid trimmings have the stronger wire hooks than the flexible trimmings. Also, the clothing carrier is stronger in semi-rigid sets, designed in terms of lower flexibility, as in flexible sets.

Aus dem Stand der Technik sind verschiedene Ausführungen von Garniturträgern bekannt, wobei diese in der Regel mehrschichtig ausgeführt sind. Die DE 10 2006 016 832 offenbart einen Garniturträger aus mindestens zwei Schichten, einer Unterschicht und einer Deckschicht. In der Unterschicht werden die Drahthäkchen verankert. Die Deckschicht hingegen ermöglicht ein ungestörtes Schwingen der Drahthäkchen, was im Besonderen bei einer Anwendung in der Kardierung wichtig ist. Die Unterschicht wird aus einem Vliesstoff gebildet, wobei sich das Material des Vliesstoffes vom Material der Deckschicht unterscheidet.
Die CH 636 134 offenbart einen Garniturträger bestehend aus einem Grundkörper mit darin eingebetteten Verstärkungseinlagen. Der Grundkörper ist aus einem elastischen Kunststoff und die Verstärkungseinlagen aus Gewebe oder Gewebeschichten hergestellt.Various designs of clothing carriers are known from the prior art, which are usually carried out in multiple layers. The DE 10 2006 016 832 discloses a clothing carrier of at least two layers, a backsheet and a topsheet. In the lower layer the wire hooks are anchored. The cover layer, however, allows undisturbed swinging of the wire hooks, which is particularly important in an application in the carding. The underlayer is formed of a nonwoven fabric, wherein the material of the nonwoven fabric is different from the material of the cover layer.
The CH 636 134 discloses a clothing carrier consisting of a base body with embedded reinforcing inserts. The main body is made of an elastic plastic and the reinforcing inserts made of fabric or fabric layers.

In der DE 74 14 314 wird eine bekannte Ausführung von Garniturträgern, welche aus mehreren Gewebeschichten besteht, dahingehend verbessert, dass mindestens eine Schicht aus einem Vliesstoff eingefügt wird.In the DE 74 14 314 For example, a known embodiment of clothing carriers consisting of a plurality of fabric layers is improved in that at least one layer of a nonwoven fabric is inserted.

Die CH 704 412 offenbart einen Garniturträger, welcher aus einem Vlies besteht, das aus einer bestimmten Mischung von verschiedenen Fasertypen hergestellt wird. Zur Anwendung kommen dabei insbesondere Schrumpffasern, welche bei einer thermischen Behandlung im Herstellungsprozess zu einer Verfestigung des Vlieses führen.The CH 704 412 discloses a clothing carrier which consists of a nonwoven fabric made from a particular blend of different fiber types. In particular, shrink fibers are used, which in the case of a thermal treatment in the production process lead to a solidification of the nonwoven.

Die GB 2 142 572 A offenbart ein mehrlagiger Garniturträger, dessen Oberfläche mit einer PUR Schicht, die zur Verbesserung der dauerelastischen Eigenschaften des Garniturträgers beiträgt, versehen ist.The GB 2 142 572 A discloses a multi-layer clothing carrier whose surface is provided with a PUR layer, which contributes to the improvement of the permanently elastic properties of the clothing carrier.

Alle aus dem Stand der Technik bekannten Garniturträger haben den Nachteil, dass sie aus mehreren Schichten aufgebaut werden oder aus einer bestimmten Mischung von verschiedenen Fasern bestehen, wobei die unterschiedlichen Schichten respektive die verschiedenen Fasern miteinander verbunden werden müssen. Die Notwendigkeit eines schichtweisen Aufbaus oder der Verwendung verschiedener Materialien bei einem Vlies für einen Garniturträger erscheint dadurch zwingend, dass einerseits eine starke Verankerung der Drahthäkchen im Garniturträger und andrerseits eine gewisse Beweglichkeit der Garniturspitzen und auch deren Sitz im Garniturträger gewährleistet sein muss. Nachteilig an Garniturträgern nach dem Stand der Technik sind auch relativ schwache Rückstellkräfte, welche die Garniturspitzen nach einer Auslenkung jeweils in die ursprüngliche Position zurückbringen. Dies ist auch darin begründet, dass bekannte Garniturträger nach kurzer Zeit ausleiern und dadurch die Garniturspitzen im Garniturträger zu viel Spiel aufweisen. Dies führt zum sogenannten Überreissen der Garnitur.All known from the prior art clothing carrier have the disadvantage that they are composed of several layers or consist of a certain mixture of different fibers, wherein the different layers or the different fibers must be connected to each other. The necessity of a layered structure or the use of different materials in a fleece for a clothing carrier appears imperative that on the one hand a strong anchoring of the wire hooks in the clothing carrier and on the other hand a certain mobility of the clothing tips and their seat must be guaranteed in the clothing carrier. A disadvantage of clothing carriers according to the prior art are also relatively weak restoring forces, which bring the clothing tips after a deflection in each case in the original position. This is also due to the fact that known clothing wearer after a short time and thereby have the clothing tips in the clothing carrier too much game. This leads to the so-called tearing of the clothing.

Der Erfindung liegt die Aufgabe zugrunde, einen Garniturträger zu schaffen, welcher einen einfachen Aufbau und eine für die Verankerung von Drahthäkchen notwendige Festigkeit aufweist und trotzdem die notwendige Beweglichkeit der Drahthäkchen zulässt.The invention has for its object to provide a clothing carrier, which has a simple structure and a necessary for the anchoring of wire tokets strength and still allows the necessary mobility of the wire tokens.

Die Aufgabe wird gelöst durch die Merkmale im kennzeichnenden Teil der unabhängigen Ansprüche.The object is solved by the features in the characterizing part of the independent claims.

Zur Lösung der Aufgabe wird ein Garniturträger für flexible oder halbstarre Garnituren vorgeschlagen , welcher ein durch Vernadelung verfestigtes getäfeltes Wirrvlies ist, wobei das Wirrvlies aus Polyester (PES)-Fasern oder Polyamid (PA)-Fasern gebildet ist und mit einem Polymer imprägniert ist.To solve the problem, a clothing carrier for flexible or semi-rigid sets is proposed, which is a screened by needle punched paneled random web, said the random web is formed of polyester (PES) fibers or polyamide (PA) fibers and impregnated with a polymer.

Unter einem Wirrvlies ist ein textiles Flächengebilde aus Fasern oder Filamenten zu verstehen, das durch die lose Aneinanderreihung und Aufeinanderschichtung ungeordneter Fasern oder Filamente entsteht. Es wird bei der vorliegenden Erfindung kein Unterschied gemacht zwischen der Verwendung von Stapelfasern und Endlosfilamenten. Ein Vlies kann aus Längs-, Längs- und Quer-, Querfasern oder -filamenten oder aus einer vollkommenen Wirrlage bestehen, wobei bei einer Wirrlage das Vlies als Wirrvlies bezeichnet wird. Sind die Fasern oder Filamente in einer Richtung ausgelegt, spricht man von einem Unidirektionalen Vlies.A random web is to be understood as meaning a textile fabric made of fibers or filaments which results from the loose juxtaposition and stacking of disordered fibers or filaments. There is no difference in the present invention between the use of staple fibers and continuous filaments. A fleece may consist of longitudinal, longitudinal and transverse, transverse fibers or filaments or of a complete random orientation, wherein in a random orientation the fleece is referred to as a random fleece. If the fibers or filaments are designed in one direction, this is called a unidirectional nonwoven.

Zur Erlangung der für einen Garniturträger wesentlichen Eigenschaften haben sich zur Wirrvliesbildung Polyester (PES)-Fasern oder Polyamid (PA)-Fasern als geeignet herausgestellt. Bevorzugterweise werden die Fasern als Stapelfasern mit einer Stapellänge von 30 mm bis 80 mm und einer Faserfeinheit von 1,0 dtex bis 5,0 dtex verwendet. Die spezifische Festigkeit beträgt 25 cN/tex bis 60 cN/tex. Alternativ können auch Endlos-Filamente mit derselben Faserfeinheit und Festigkeit verwendet werden.In order to obtain the characteristics essential for a clothing carrier, polyester (PES) fibers or polyamide (PA) fibers have proven to be suitable for random web formation. Preferably, the fibers are used as staple fibers having a staple length of 30 mm to 80 mm and a fiber fineness of 1.0 dtex to 5.0 dtex. The specific strength is 25 cN / tex to 60 cN / tex. Alternatively, continuous filaments having the same fiber denier and strength can be used.

Bevorzugterweise wird das Wirrvlies aus Polyamid-Fasern hergestellt. Polyamid-Fasern weisen im Vergleich zu Polyester-Fasern ein höheres Feuchteaufnahmevermögen auf, was sich auch in einer höheren Benetzbarkeit ausdrückt. Dadurch wird eine erhöhte Haftung des bei der Imprägnierung verwendeten Polymers an der einzelnen Faser erreicht. Auch zeigt die Polyamid-Faser ein höheres Wiedererholungsvermögen nach einer mechanischen Belastung als die Polyester-Faser. Das heisst nach einer mechanischen Belastung findet die Polyamid-Faser eher in den ursprünglichen Zustand zurück als die Polyester-Faser. Diese mechanischen Rückstellkräfte führen in der vorliegenden Anwendung zu einer erhöhten Standzeit des Garniturträgers.Preferably, the random web is made of polyamide fibers. Polyamide fibers have a higher moisture absorption capacity compared to polyester fibers, which is also expressed in a higher wettability. This achieves increased adhesion of the polymer used in the impregnation to the individual fiber. Also, the polyamide fiber shows a higher recovery after mechanical stress than the polyester fiber. This means that after a mechanical load, the polyamide fiber returns to its original state rather than the polyester fiber. These mechanical restoring forces lead in the present application to an increased service life of the clothing wearer.

Wie aus dem Stand der Technik bekannt, werden die zur Bildung des Wirrvlieses verwendeten Fasern nach dem Krempelprozess auf einem Band als Wirrvliesschicht abgelegt und im Anschluss mit einem Vliesquerleger übereinandergeschichtet. Durch die Quertäfelung mehrerer Wirrvliesschichten wird ein getäfeltes Wirrvlies mit Vorzugsrichtung der Fasern in Querrichtung gebildet. Unter der Querrichtung ist die orthogonal zu einer Laufrichtung des Bandes auf dem die Wirrvliesschicht abgelegt wird zu verstehen. Durch die Täfelung (Doublierung) wird das gewünschte Flächengewicht des Wirrvliesanteils des Garniturträgers erreicht. Erfindungsgemäß ist das Wirrvlies aus mindestens 30 - 60 Täfelungen, bevorzugterweise aus 40 Täfelungen aufgebaut.As known from the prior art, the fibers used to form the random web are laid on a band as a random nonwoven layer after the carding process and are then stacked on top of one another using a nonwoven cross-bar. By the Quertäfelung several random fleece layers is a paneled random web formed with preferential direction of the fibers in the transverse direction. Under the transverse direction is to be understood orthogonal to a running direction of the tape on which the random fleece layer is deposited. By the paneling (doubling), the desired basis weight of the random web portion of the clothing wearer is achieved. According to the invention, the random web is composed of at least 30-60 paneling, preferably of 40 paneling.

Ein getäfeltes Wirrvlies wird nur begrenzt durch sich selbst zusammengehalten. Um diesen begrenzten Zusammenhalt zu verbessern wird das Wirrvlies einem Vernadelungsprozess unterzogen und dadurch eine Vliesverfestigung erzielt. Eine Vernadelung kann in einer oder auch mehreren Passagen durchgeführt werden. Weiter ist es durch gezieltes Verziehen (Recken) des Vlieses vor oder nach dem Vernadelungsprozess möglich die Faserorientierung im Vlies zu beeinflussen. Dadurch können definierte Kraft-Dehnungseigenschaften des Vlieses in Längs- und Querrichtung eingestellt werden. Durch die Vernadelung wird eine Erhöhung der Dichte des Wirrvlieses bewirkt, es werden bis zu 0.3 g/cm3 erreicht.A paneled random fleece is held together only to a limited extent by itself. In order to improve this limited cohesion, the random web is subjected to a needling process, thereby achieving a web bonding. A needling can be carried out in one or more passages. Furthermore, it is possible to influence the fiber orientation in the nonwoven by deliberate warping (stretching) of the nonwoven before or after the needling process. As a result, defined force-elongation properties of the fleece can be adjusted in the longitudinal and transverse directions. By needling an increase in the density of the random web is effected, it is achieved up to 0.3 g / cm 3 .

Nach der Vernadelung wird das Wirrvlies ein erstes Mal durch Kalanderwalzen geführt. Dadurch werden Dickenunterschiede ausgeglichen und eine definierte Dicke respektive Dichte eingestellt.After needling, the random mat is passed through calender rolls for the first time. Characterized thickness differences are compensated and set a defined thickness or density.

Eine wichtige Eigenschaft eines Garniturträgers ist die Dauerelastizität. Die später eingesetzten Garniturspitzen werden derart beansprucht, dass sich die Drahthäkchen hin und her bewegen. Damit die Drahthäkchen in ihrer Befestigung nicht ausleiern, muss der Garniturträger eine hohe Dauerelastizität aufweisen. Zur Erhöhung der Dauerelastizität wird der Garniturträger nach der ersten Kalandrierung mit einem Polymer imprägniert.An important feature of a clothing wearer is the permanent elasticity. The clothing tips used later are claimed in such a way that the wire hooks move back and forth. To ensure that the wire hooks do not become loose in their fastening, the clothing carrier must have a high permanent elasticity. To increase the permanent elasticity of the clothing carrier is impregnated after the first calendering with a polymer.

Dabei wird das Polymer, beispielsweise Latex (Acrylnitril), in Form einer wässrigen Dispersion bereitgestellt. Bevorzugterweise beträgt der Wasseranteil 50 bis 70 Prozent, bevorzugterweise weniger als 60 Prozent. Das Wirrvlies wird in dieser Dispersion getaucht, wodurch das Wirrvlies in seinen Hohlräumen die Dispersion aufnimmt. Anschliessend wird das Wirrvlies durch eine zweite Kalandrierung abgepresst zur Abführung überflüssiger Dispersion und in einem weiteren Schritt stabilisiert und getrocknet.In this case, the polymer, for example latex (acrylonitrile), is provided in the form of an aqueous dispersion. Preferably, the proportion of water is 50 to 70 percent, preferably less than 60 percent. The random web is dipped in this dispersion, whereby the random web absorbs the dispersion in its cavities. Subsequently, the random web is pressed by a second calendering for the removal of superfluous dispersion and stabilized and dried in a further step.

Zur Stabilisierung wird üblicherweise ein Infrarot-Feld verwendet, wodurch ein Sedimentieren des Polymers verhindert wird. Die Stabilisierung und Trocknung des Wirrvlieses kann in einem beheizten Raum erfolgen durch den das Wirrvlies transportiert wird. Dabei kann das Wirrvlies auf Bändern, Walzen oder sonstigen geeigneten Mitteln, beispielsweise besaugte Trommeln eines Siebtrommeltrockners, durch den beheizten Raum geführt werden.For stabilization, an infrared field is usually used, thereby preventing sedimentation of the polymer. The stabilization and drying of the random fleece can take place in a heated space through which the random fleece is transported. In this case, the random web can be guided on belts, rollers or other suitable means, for example, evacuated drums of a perforated drum dryer, through the heated space.

In einer weiteren Ausführungsform können zur Stabilisierung und Trocknung des Wirrvlieses auch beheizte Walzen verwendet werden. Die Beheizung ermöglicht die Schaffung glatter Oberflächen, respektive eine Einstellung der Oberflächenbeschaffenheit des Garniturträgers.In a further embodiment, heated rolls can also be used to stabilize and dry the random web. The heating allows the creation of smooth surfaces, respectively, an adjustment of the surface texture of the clothing wearer.

Die Imprägnierung hat ebenfalls eine Erhöhung der Dichte zur Folge. Mit Hilfe der Veränderung des Polymeranteils in der wässrigen Dispersion kann die eingelagerte Polymermenge im Garniturträger bestimmt werden. Dies wirkt sich aus auf die Elastizität und die Dichte des Garniturträgers, es werden Dichten von 0,4 g/cm3 bis 0,5 g/cm3 erreicht. Dabei hat das Polymer einen Anteil von 20 bis 60 Prozent am Gewicht des imprägnierten Wirrvlieses.The impregnation also results in an increase in density. With the help of the change of the polymer content in the aqueous dispersion, the stored amount of polymer in the clothing carrier can be determined. This has an effect on the elasticity and the density of the clothing carrier, densities of from 0.4 g / cm 3 to 0.5 g / cm 3 are achieved. The polymer has a proportion of 20 to 60 percent of the weight of the impregnated random web.

Vorteilhafterweise erreicht das imprägnierte Wirrvlies ein spezifisches Flächengewicht von mehr als 1'400 g/m2. Es hat sich gezeigt, dass imprägnierte Wirrvliese mit einem geringeren spezifischen Flächengewicht eine Verringerung der Haltekräfte der darin eingestochenen Drahthäkchen zur Folge haben und dadurch ein rascheres Ausleiern der Drahthäkchen fördern. Bevorzugterweise beträgt das spezifische Flächengewicht des imprägnierten Wirrvlieses mehr als 1'600 g/m2.Advantageously, the impregnated random nonwoven reaches a specific basis weight of more than 1,400 g / m 2 . It has been found that impregnated random webs having a lower specific basis weight result in a reduction of the holding forces of the wire hooks pierced therein and thereby promote a more rapid emptying of the wire hooks. Preferably, the specific basis weight of the impregnated random mat is more than 1,600 g / m 2 .

Erfindungsgemäß ist durch Kaschieren mit einer Polyurethan (PUR)-Folie ein Strukturausgleich zumindest einer Oberfläche des Wirrvlieses vorgesehen. Durch das Kaschieren wird die PUR-Folie mit dem Wirrvlies verbunden. Im Besonderen eignet sich das Thermokaschieren, bei welchem unter Wärmeeinfluss und unter Druck die PUR-Folie auf den Garniturträger aufgebracht wird, beispielsweise mit Hilfe von beheizten Walzen. Die dabei zur Anwendung kommende PUR-Folie weist eine Stärke von 0,1 mm bis 0,5 mm auf, bevorzugterweise werden PUR-Folien mit einer Stärke von 0,1 mm bis 0,3 mm verwendet. Dieser durch die Folie geschaffene Überzug hat den Vorteil, dass die Oberfläche des Garniturträgers einfach zu reinigen ist und im Einsatz die am Garniturträger vorbeigeführten Fasern zu weniger Anhaftungen führen. Zudem trägt die PUR-Folie zur Verbesserung der dauerelastischen Eigenschaften des Garniturträgers bei. Die auf das Wirrvlies aufgebrachte PUR-Folie erhöht die Rückhaltekraft des Wirrvlieses bezüglich der später eingesetzten Drahthäkchen.According to the invention, by means of lamination with a polyurethane (PUR) film, a structure compensation of at least one surface of the random fleece is provided. By laminating the PUR film is connected to the random web. In particular is the thermal lamination, in which under heat influence and under pressure, the PUR film is applied to the clothing carrier, for example by means of heated rollers. The PUR film used in this case has a thickness of 0.1 mm to 0.5 mm, preferably PUR films are used with a thickness of 0.1 mm to 0.3 mm. This created by the film coating has the advantage that the surface of the clothing wearer is easy to clean and in use lead the lead past the clothing carrier fibers to less clinging. In addition, the PUR film contributes to the improvement of the permanently elastic properties of the clothing carrier. The applied to the random web PUR film increases the retention force of the random web with respect to the later used wire hooks.

Durch die Verwendung von beheizten Walzen oder Bändern bei der Thermokaschierung wird die PUR-Folie mit einer Oberflächenstruktur versehen. Durch den Druck welche die Walzen resp. Bänder auf die PUR-Folie ausüben wird eine auf den Walzen resp. Bändern vorhandene Struktur auf die Folie übertragen.By using heated rollers or belts in the thermal lamination, the PUR film is provided with a surface structure. By the pressure which the rollers resp. Bands on the PUR film exercise one on the rollers resp. Tapes existing structure transferred to the film.

Auch ist die Faserreibung auf einer strukturierten Oberfläche wesentlich geringer als auf einer glatten Oberfläche, dies ist darin zu begründen, dass die tatsächliche Berührungsfläche zwischen einer Faser und der Oberfläche des Garniturträgers durch die Strukturierung der Oberfläche verkleinert wird. Bevorzugterweise weist die Oberfläche der PUR-Folie eine wellenartige Struktur auf. Die wellenartige Struktur wird durch die beheizten Walzen resp. Bänder während des Kaschierens auf die Oberfläche der PUR-Folie übertragen.Also, the fiber friction on a structured surface is much lower than on a smooth surface, this being because the actual contact area between a fiber and the surface of the clothing carrier is reduced by the structuring of the surface. Preferably, the surface of the PUR film has a wave-like structure. The wave-like structure is due to the heated rollers resp. Transfer tapes to the surface of the PUR film during lamination.

Die Oberfläche der PUR-Folie weist bevorzugterweise eine Oberflächenrauheit Ra von 5 µm bis 30 µm, besonders bevorzugt 7 µm bis 20 µm auf. Die grösste Höhendifferenz Rz beträgt mehr als 30 µm. Die Kennzahlen zur Oberflächenrauheit Ra und Rz sind dabei mit dem Tastschnittverfahren nach der Norm DIN EN ISO 4287 (Ausgabe 1998) zu bestimmen. Das dabei zur Verwendung kommende Tastschnittgerät ist durch die Norm EN ISO 3274 (Ausgabe 1997) in seinen Nenneigenschaften bestimmt.The surface of the PUR film preferably has a surface roughness Ra of 5 μm to 30 μm, more preferably 7 μm to 20 μm. The largest height difference Rz is more than 30 μm. The surface roughness Ra and Rz are to be determined using the stylus method according to the standard DIN EN ISO 4287 (Edition 1998). The stylus used for this purpose is determined by the standard EN ISO 3274 (Edition 1997) in its nominal properties.

Es hat sich gezeigt, dass eine strukturierte Oberfläche oder auch eine erhöhte Rauhigkeit der Oberfläche gegenüber einer glatten Oberfläche der PUR-Folie zu einem besseren Abgleiten der Fasern auf der Oberfläche sowie zu einer Verminderung der Anhaftung von Schmutz führt. Dies trägt auch zu einer Verbesserung der Reinigung der Garniturträger bei.It has been found that a structured surface or even an increased roughness of the surface compared to a smooth surface of the PUR film leads to a better sliding of the fibers on the surface and to a reduction of the adhesion of dirt. This also contributes to an improvement in the cleaning of the clothing carrier.

Erfindungsgemäß ist vor dem Kaschieren eine Pulverbeschichtung für den Strukturausgleich und zur Haftungserhöhung vorgesehen. Bei dem dabei verwendeten Pulver handelt es sich ebenfalls um Polyester (Co-PES). Das in kleinsten Mengen aufgebrachte Pulver ermöglicht eine Egalisierung von herstellungsbedingten Unebenheiten im Wirrvlies und führt zu einer Verbesserung des durch das Kaschieren zu erreichenden Strukturausgleichs. Dabei hat sich das Auftragen von 25 g/m2 bis 30 g/m2 Pulver aus Co-PES als besonders geeignet herausgestellt. Das aufgebrachte Pulver dient auch als Haftvermittler und trägt zu einer besseren Verbindung zwischen dem Wirrvlies und der PUR-Folie bei. Das Pulver weist bevorzugterweise eine Feinheit von 200 µm bis 500 µm auf.According to the invention, a powder coating for the structure compensation and adhesion increase is provided before laminating. The powder used is likewise polyester (Co-PES). The powder applied in very small amounts makes it possible to level out production-related unevennesses in the random web and leads to an improvement in the structure compensation to be achieved by laminating. In this case, the application of 25 g / m 2 to 30 g / m 2 powder of Co-PES has been found to be particularly suitable. The applied powder also serves as a bonding agent and contributes to a better connection between the random web and the PUR film. The powder preferably has a fineness of 200 μm to 500 μm.

In einer weiteren Ausführungsform wird zur Beeinflussung der Flexibilität eine oder mehrere Vliesschichten in den Garniturträger eingebracht, welche als unidirektionale Vliese ausgeführt sind. Durch das Einbringen einer unidirektionalen Schicht wird der Garniturträger starrer gegen mechanische Belastungen in Richtungen parallel zu der unidirektionalen Richtung. Durch eine entsprechende Anordnung der unidirektionalen Schicht kann beispielsweise die Flexibilität der Garniturspitzen in Schwingungsrichtung der Garniturspitzen beeinflusst werden.In another embodiment, one or more nonwoven layers is introduced into the clothing carrier, which are designed as unidirectional nonwovens for influencing the flexibility. By incorporating a unidirectional layer, the clothing carrier becomes more rigid against mechanical stresses in directions parallel to the unidirectional direction. By an appropriate arrangement of the unidirectional layer, for example, the flexibility of the clothing tips in the direction of oscillation of the clothing tips can be influenced.

Das Verfahren zur Herstellung eines Garniturträgers für flexible oder halbstarre Garnituren umfasst unter anderem die folgenden Schritte:

  • Bildung eines getäfelten Wirrvlieses aus Polyester (PES)-Fasern oder Polyamid (PA)-Fasern
  • Vernadelung des getäfelten Wirrvlieses
  • Erste Kalandrierung nach der Vernadelung zur Einstellung der Dicke und Dichte des Wirrvlieses
  • Imprägnierung des erstmalig kalandrierten Wirrvlieses
  • Zweite Kalandrierung des imprägnierten Wirrvlieses zur Einstellung der Soll-Dicke des Wirrvlieses
The method for producing a clothing carrier for flexible or semi-rigid trimmings comprises, inter alia, the following steps:
  • Formation of a paneled random mat of polyester (PES) fibers or polyamide (PA) fibers
  • Needling of the paneled random fleece
  • First calendering after needling to adjust the thickness and density of the random mat
  • Impregnation of the first calendered random fleece
  • Second calendering of the impregnated random fleece for setting the desired thickness of the random fleece

Für das Imprägnieren wird das Wirrvlies in eine wässrige Lösung von Latex getaucht, wobei sich das Wirrvlies mit dem Imprägniermittel vollsaugt. Die überschüssige Menge der wässerigen Lösung wird durch eine anschliessende zweite Kalandrierung abgequetscht und die endgültige Dicke des Wirrvlieses eingestellt.For impregnation, the random fleece is immersed in an aqueous solution of latex, whereby the random fleece is soaked with the impregnating agent. The excess amount of the aqueous solution is squeezed off by a subsequent second calendering and adjusted the final thickness of the random web.

Die heute gebräuchlichen Garniturträger weisen eine Dicke von 3 mm bis 4 mm auf. Es sind jedoch auch andere Dicken von Garniturträgern möglich.
Der Garniturträger wird zur Herstellung einer flexiblen oder halbstarren Garnitur für die Bearbeitung von textilen Fasern verwendet. Bei der Herstellung der Garnitur werden in einem Setzvorgang Drahthäkchen durch den Garniturträger hindurch gestochen. Die Drahthäkchen bilden auf der Oberseite der Garnitur die Garniturspitzen. Beim Setzvorgang werden die Drahthäkchen in einem den späteren Anforderungen an die Garnitur entsprechenden Abstand voneinander angeordnet. Die Anzahl der dadurch vorhandenen Garniturspitzen pro Fläche wird als Spitzendichte bezeichnet. Aufgrund mechanischer Gegebenheiten der verwendeten Maschinen in der Herstellung der Garnituren ist die in einem Setzvorgang maximal zu erreichende Spitzendichte begrenzt. Ein minimaler Abstand zwischen den Drahthäkchen kann nicht unterschritten werden aufgrund der Drahtgeometrie und der Konstruktion der Setzwerkzeuge.The currently used clothing carrier have a thickness of 3 mm to 4 mm. However, other thicknesses of clothing carriers are possible.
The clothing carrier is used to make a flexible or semi-rigid garnish for processing textile fibers. In the manufacture of the clothing wire hooks are pricked through the clothing carrier in a setting process. The wire hooks form on the top of the clothing the clothing tips. During the setting process, the wire hooks are arranged in a distance corresponding to the later requirements of the clothing. The number of clothing peaks per surface is referred to as peak density. Due to mechanical conditions of the machines used in the production of trimmings the maximum achievable in a setting operation peak density is limited. A minimum distance between the wire hooks can not be undershot due to the wire geometry and the construction of the setting tools.

Im Folgenden wird die Erfindung anhand einer beispielhaften Ausführungsform erklärt und durch Zeichnungen näher erläutert.

FIG. 2
Schematic representation of a clothing carrier according to the invention

In Figur 1 ist ein bekannter Garniturträger 1 mit eingesetzter flexibler Garnitur 2 dargestellt. Der Garniturträger 1 ist aus mehreren gewobenen Textilschichten 3 zusammengesetzt, die durch Bindemittel oder durch Vulkanisieren mit Kautschuk oder synthetischem Kautschuk zusammengehalten werden. Zusätzlich zu den Textilschichten 3 ist eine Kautschukschicht 5 als Deckschicht 5 vorhanden. Die durch den Garniturträger 1 durchgestochenen Drahthäkchen 4 werden im mehrlagigen Gewebe 3 gehalten. Die Drahthäkchen 4 werden im Betrieb stark beansprucht und sind entsprechend im mehrlagigen Garniturträger 1 verankert. Flexible Garnituren 2, wie auch halbstarre Garnituren, werden meist in Streifen mit einer bestimmten Breite b und einer Dicke d gefertigt und anschliessend in so genannten Deckeln eingesetzt oder auf Walzen aufgezogen.In FIG. 1 a known clothing carrier 1 is shown with inserted flexible clothing 2. The clothing carrier 1 is composed of several woven textile layers 3, which are held together by binders or by vulcanization with rubber or synthetic rubber. In addition to the textile layers 3, a rubber layer 5 is present as a cover layer 5. The pierced through the clothing carrier 1 wire hook 4 are held in the multi-layer fabric 3. The wire hooks 4 are heavily stressed during operation and are anchored accordingly in the multi-layered clothing carrier 1. Flexible sets 2, as well as semi-rigid sets are usually made in strips with a certain width b and a thickness d and then used in so-called lids or mounted on rollers.

In Figur 2 ist eine Ausführungsform des Garniturträgers nach der Erfindung schematisch dargestellt. Der Garniturträger 1 ist in der Darstellung einschichtig mit einem Überzug 12 gezeigt. Der Garniturträger 1 ist ein getäfeltes Wirrvlies aus PES-Fasern (10). Das getäfelte Wirrvlies wurde durch Vernadelung verfestigt und durch eine erste Kalandrierung auf eine bestimmte Dicke gebracht. Durch ein anschliessendes Imprägnieren des Garniturträgers 1 wurde ein Polymer 11 in den Garniturträger 1 eingebracht. Durch eine abschliessende zweite Kalandrierung wird die Dicke d erreicht. Auf der Oberseite des Garniturträgers 1 ist über die gesamte Breite b ein Überzug 12 durch Kaschieren mit einer PUR-Folie aufgebracht. Die Oberseite entspricht der Seite, auf welcher später die Drahthäkchen herausstehen und die Garnitur bilden. Der aufgebrachte Überzug 12 dient nicht nur einer Verbesserung der Oberflächenbeschaffenheit des Garniturträgers 1, sodass die Anhaftung von Staub und Schmutz vermindert werden kann, sondern auch der Verbesserung der dauerelastischen Eigenschaften des Garniturträgers.In FIG. 2 an embodiment of the clothing carrier according to the invention is shown schematically. The clothing carrier 1 is shown in the illustration as a single layer with a coating 12. The clothing carrier 1 is a paneled random web of PES fibers (10). The paneled random fleece was consolidated by needling and brought to a certain thickness by a first calendering. By a subsequent impregnation of the clothing carrier 1, a polymer 11 was introduced into the clothing carrier 1. By a final second calendering the thickness d is achieved. On the upper side of the clothing carrier 1, a coating 12 is applied over the entire width b by laminating with a PUR film. The upper side corresponds to the side on which later the wire hooks protrude and form the clothing. The applied coating 12 serves not only to improve the surface finish of the clothing carrier 1, so that the adhesion of dust and dirt can be reduced, but also to improve the permanently elastic properties of the clothing wearer.

Die Garniturträger werden in der Regel als endlose Bahnen mit einer bestimmten Länge hergestellt und durch den Setzvorgang mit Drahthäkchen zur Bildung der Garniturspitzen bestückt. Nach Abschluss des gesamten Herstellungsprozesses werden die mit Drahthäkchen bestücken Garniturträger in verwendungsfertige Streifen mit der Breite b geschnitten. Dabei beträgt die Breite b abhängig vom Verwendungszweck zwischen 15 mm und 150 mm.The clothing carrier are usually produced as endless webs with a certain length and equipped by the setting process with wire hooks to form the clothing tips. After completion of the entire production process, the clothing carriers equipped with wire hooks are cut into ready-to-use strips of width b. The width b depends on the intended use between 15 mm and 150 mm.
