Description

Diese Erfindung betrifft eine Versteifungseinlage. Diese Erfindung betrifft ebenfalls ein Verfahren zur Herstellung einer derartigen Versteifungseinlage.This invention relates to a stiffening insert. This invention also relates to a method for Manufacture of such Reinforcing insert.

Derartige Einlagen werden seit vielen Jahren zur Verstärkung von Bekleidungsstücken, insbesondere in der Damen- und Herrenkonfektion eingearbeitet. Je nach Verabeitungsmethode können sich diese z.B. über das ganze Vorderteil eines Sakkos erstrecken oder werden nur als sogenannter Chest-Canvas verarbeitet. Die Versteifungseinlagen sollen dem Vorderteil des Bekleidungsstückes eine Formstabilität verleihen, wobei zusätzlich von den jeweils verwendeten Versteifungseinlagen auch ein gutes Rückform- bzw. Rücksprungvermögen erwartet wird.Such deposits have been used as reinforcements for many years of clothing, especially in the women's and Men's clothing incorporated. Depending on the method of application can these e.g. over the whole front part of a jacket stretch or become just a so-called chest canvas processed. The stiffening inserts should be the front part give the garment dimensional stability, wherein additionally from the stiffening inserts used in each case good recovery and recovery capacity is also expected becomes.

Üblicherweise wurden bisher spezielle Gewebe, meist leinwandbindige Gewebe, auf dem Markt verwendet, wobei diese Gewebe einen Gewichtsbereich von etwa 120-260 g/m2 haben. Auch entsprechende Gewirke sind vereinzelt am Markt anzutreffen. Up to now, special fabrics, mostly plain-weave fabrics, have been used on the market, these fabrics having a weight range of approximately 120-260 g / m 2 . Corresponding knitted fabrics can also be found on the market.

Um das gewünschte gute Rückformvermögen, vor allem in Schußrichtung, zu erzielen, werden bei diesen Geweben und Gewirken im Schuß bevorzugt grobe Garne eingesetzt, die hauptsächlich im Halbkammgarnverfahren ausgesponnen werden. Die eingesetzten Faserkomponenten sind in erster Linie nativen Ursprungs. Insbesondere werden im Schuß Tierhaare verwendet, wobei je nach Einlagetyp diese Garne im Schußwechsel mit reinen Viskosegarnen, Wollgarnen oder Mischungen daraus in das Gewebe eingetragen werden. Die Tierhaare können auch in Verbindung mit groben Viskosefasern ausgesponnen werden. Besonders bevorzugt werden Haare von afrikanischen Ziegen oder auch Yakhaare verwendet. Gerne und besonders häufig werden auch Pferdehaare, insbesondere Zwirne aus diesen Haaren, eingesetzt. Nachteilig ist hier jedoch, daß diese Pferdehaare verhältnismäßig teuer sind.To achieve the desired good recovery, especially in Weft direction to achieve these fabrics and Knitted fabrics used in the weft preferred coarse yarns mainly spun using the semi-worsted process. The fiber components used are primarily native origin. In particular, animal hairs are shot used, depending on the type of insert these yarns in Change of weft with pure viscose yarns, wool yarns or Mixtures of these are introduced into the tissue. The Animal hair can also be combined with coarse viscose fibers be spun out. Hairs from African goats or yak hair is used. Happy and horsehair, especially twists, is also particularly common from these hairs. The disadvantage here is that these horse hairs are relatively expensive.

Die Verwendung von Tierhaaren hat weitere erhebliche Nachteile. So müssen Tierhaare erheblichen Reinigungsverfahren unterzogen werden, was dazu führt, daß dieses Verfahren sehr aufwendig und folglich auch teuer ist. Außerdem ist die Verwendung von Tierhaaren nachteilig, weil sie häufig Allergien bei den Arbeitern auslösen können, die die Reinigung dieser Tierhaare vornehmen müssen. Außerdem unterliegen die Garne, die aus Tierhaaren oder Mischungen daraus hergestellt sind, sehr starken Feinheitsschwankungen (Nummernschwankungen), was wiederum Gewichtschwankungen im Fertigprodukt nach sich zieht.The use of animal hair has other significant ones Disadvantage. So animal hair must be substantial Cleaning procedures are subjected, which leads to the fact that this process is very complex and consequently also expensive. In addition, the use of animal hair is disadvantageous because they can often trigger allergies to workers who have to clean these pet hairs. Moreover subject to the yarns that are made from animal hair or blends made from it, very strong fluctuations in fineness (Number fluctuations), which in turn fluctuates in weight Finished product entails.

Im Schuß werden außerdem Mehrkomponentengarne, sogenannte Coregarne, eingesetzt, die seit einiger Zeit auch im Drefverfahren hergestellt werden. Diese Garne enthalten als sprunggebende Komponente ebenfalls Tierhaare oder bevorzugt synthetische Monofile bzw. Multifilamente. Charakteristisch ist der Aufbau aus einer oder mehreren sprunggebenden Komponenten, sowie aus Mantelfasern. Multi-component yarns, so-called Coregarne, used for some time in the Drefverfahren be produced. These yarns contain as jumping component also animal hair or preferred synthetic monofilaments or multifilaments. Characteristic is the structure of one or more leaping Components, as well as from sheath fibers.

Vor allem bei den Garnen, die ein synthetisches Monofil enthalten, treten immer wieder Probleme der Art auf, daß das Monofil in diesen Garnen zu Verschiebungen gegenüber den Mantelfasern neigt. An den Schnittkanten der zugeschnittenen Verstärkungseinlage treten dann die Monofile hervor und können am fertig konfektionierten Teil sogar den Oberstoff durchstechen.Especially with the yarns, which are synthetic monofilament contain problems of the kind that the Monofilament in these yarns to shift compared to the Sheath fibers tend. At the cut edges of the cut Reinforcement insert then emerge the monofilament and can even use the outer fabric on the finished part pierce.

Bei allen Versteifungseinlagen dieser Art werden in der Konfektion noch Zusatzeinlagen benötigt, um die gewünschte Versteifungswirkung zu erzielen. Die Verarbeitung dieser Einlagen und der Zusatzeinlagen benötigen aber einen hohen Fertigungs- und Materialaufwand sowie besonders große Sorgfalt bei der Ausarbeitung der Plackeinlagen, ihrer Positionierung und sauberen Pikierung. Die Plackeinlagen und die Zusatzeinlage müssen millimetergenau positioniert und durch aufwendige Nähvorgänge zu einem Gesamtplack verbunden werden.All stiffening inserts of this type are used in the Assembly still requires additional inserts to achieve the desired To achieve stiffening effect. Processing this Deposits and additional deposits, however, require a high level Manufacturing and material costs as well as particularly large Care in the elaboration of the black deposits, their Positioning and clean pricking. The black deposits and the additional insert must be positioned with millimeter precision and connected to an overall patch by complex sewing processes become.

Eine andere Art von Plackeinlage ist in EP 0 514 563 beschrieben. Es handelt sich um ein Kettgewirke, das im Schuß mit sprungkräftigen Fäden aus Coregarnen versehen ist. Dieses Kettgewirke wird auf einer Vliesraschelmaschine mit einem Basisvlies verbunden. Die daraus entstandene Plackeinlage dient als Zusatzverstärkungseinlage für die eigentliche Plackeinlage zur Absicherung von z.B. Schulter-, Achsel- und Armlochbereichen. Bedingt durch die Herstellungsweise ist jedoch die Dicke und das Volumen des Basisvlieses äußerst begrenzt, da bei der Maschenbildung die Kettfäden das Basisvlies stark zusammenschnüren und somit in Kettrichtung entlang der Maschenstäbchen Einschürungen im Basisvlies entstehen, die sich bei empfindlichen Oberstoffen durch den Oberstoff abzeichnen.Another type of plack insert is described in EP 0 514 563 . It is a warp-knitted fabric that has weft-like threads made from core yarns. This warp knitted fabric is connected to a base nonwoven on a nonwoven machine. The resulting plack insert serves as an additional reinforcement insert for the actual plack insert to secure, for example, shoulder, armpit and armhole areas. Due to the manufacturing method, however, the thickness and volume of the base fleece is extremely limited, since when the stitches are formed, the warp threads constrict the base fleece strongly, thus creating constrictions in the base fleece along the wales, which can be seen in sensitive outer fabrics through the outer fabric.

Der vorliegenden Erfindung liegt daher das technische Problem zugrunde, eine Versteifungseinlage zu entwickeln, der zum einen kostengünstig herstellbar ist und zum anderen die Nachteile der oben genannten Plackeinlagen nicht aufweist sowie in der Konfektion einfach zu verarbeiten ist. Insbesondere soll sich die Versteifungseinlage nicht durch den Oberstoff von Bekleidungsstücken abzeichnen.The present invention therefore has the technical problem based on developing a stiffening insert, on the one hand is inexpensive to manufacture and the disadvantages does not have the above-mentioned black deposits as well as in the Assembly is easy to process. In particular, should the stiffening insert is not covered by the outer fabric of Draw off clothing.

Diese Probleme werden durch die Versteifungseinlage gemäß Anspruch 1 gelöst. Das Gewebe oder Gewirke kann einseitig oder auch auf der Ober- und der Unterseite jeweils mit einer Schicht aus Vlies verklebt sein.These problems are caused by the stiffening insert solved according to claim 1. The woven or knitted fabric can one-sided or on the top and bottom be glued with a layer of fleece.

Das Rückformvermögen des Vliesverbundes wird durch ein sprunggebendes Gewebe oder Gewirke erzielt. Die Schußgarne des Gewebes oder Gewirkes sind Monofile oder Multifilamente oder eine Kombination daraus. Es ist ebenfalls möglich, daß die Monofile zu einem Multifilamentgarn verzwirnt sind, das dann den sprunggebenden Schußfaden bildet. Das Material, aus dem die Schußgarne hergestellt sind, ist bevorzugt Polyamid-6, Polyamid-6,6, Polyester oder Polypropylen oder auch Mischungen aus Synthesefasern. Die Schußgarne können beispielsweise Monofile mit einem Faserdurchmesser von 0,05-0,40 mm sein.The recovery capacity of the nonwoven composite is determined by a jumping fabric or knitted fabric achieved. The weft yarns of the woven or knitted fabric are monofilaments or multifilaments or a combination of them. It is also possible that the monofilaments are twisted into a multifilament yarn that then forms the jump weft. The material from to which the weft yarns are made is preferably polyamide-6, Polyamide-6,6, polyester or polypropylene or also Mixtures of synthetic fibers. The weft yarns can for example monofilaments with a fiber diameter of 0.05-0.40 mm.

Es ist aber auch möglich, Fadenfolgen mit Monofilen und Multifilamenten sowie mit herkömmlichen, gesponnenen Fäden zu verwenden. Ebenso können als Schußgarne Multifilamente eingesetzt werden, die einen Titer im Bereich von 400 bis 2000 dtex aufweisen.But it is also possible to use thread sequences with monofilaments and Multifilaments as well as with conventional, spun threads use. Multifilaments can also be used as weft yarns be used which have a titer in the range of 400 to Have 2000 dtex.

Erfindungsgemäß ist es ebenfalls möglich, die aus EP-A-0 514 563 bekannten Kettgewirke mit der mindestens einen Schicht aus einem Vlies zu verkleben, unter Erhalt des neuen Vliesverbundes. According to the invention, it is also possible to use EP-A-0 514 563 known warp knitted fabrics with the at least one Glue layer of a fleece, while maintaining the new one Nonwoven composite.

Die Kettgarne des Gewebes oder des Gewirkes sind bevorzugt Baumwolle, Wolle oder andere native Fasern oder Viskose, Polyester, Polyamid, Polyacrylnitril oder Polypropylen oder Mischungen daraus. Bevorzugt haben die Kettgarne Feinheiten im Bereich von 25-400 dtex, bevorzugt im Bereich von 100-400 dtex. Es können auch Filamentketten verwendet werden, wobei diese zusätzlich texturiert sein können. Wenn Monofile als Kettgarne verwendet werden, können diese ebenso wie bei den oben beschriebenen Schußgarnen einen Faserdurchmesser von 0,05 bis 0,40 mm aufweisen. Natürlich ist es auch möglich, eine Verzwirnung mehrerer solcher Monofile zu einem Multifilament durchzuführen, das dann den Kettfaden darstellt.The warp yarns of the woven or knitted fabric are preferred Cotton, wool or other native fibers or viscose, Polyester, polyamide, polyacrylonitrile or polypropylene or Mixtures of these. The warp yarns preferably have delicacies in the range of 25-400 dtex, preferably in the range of 100-400 dtex. Filament chains can also be used, whereby these can also be textured. If monofilament as Warp yarns can be used as well as the weft yarns described above have a fiber diameter of Have 0.05 to 0.40 mm. Of course it is also possible a twisting of several such monofilaments into a multifilament carry out, which then represents the warp thread.

Wird ein Gewirke für den Vliesverbund dieser Erfindung verwendet, so werden in der Kette bevorzugt Multifilamente mit einer Feinheit im Bereich von 25-400 dtex eingesetzt.Becomes a knitted fabric for the nonwoven composite of this invention multifilaments are preferred in the warp used with a fineness in the range of 25-400 dtex.

Das erfindungsgemäß für die Herstellung der Versteifungseinlage verwendete Vlies kann ein Nadelvlies, ein wasserstrahlverfestigtes, bindemittelverfestigtes oder punktverschweißtes Vlies, ein Wirkvlies oder ein Schaumstoffvlies sein. Es ist auch möglich, eine Kombination dieser Materialien zu verwenden. Das Gewicht des Vlieses liegt bevorzugt in dem Bereich von 10-180 g/m2.The fleece used according to the invention for the production of the stiffening insert can be a needle fleece, a water jet-bonded, binder-bonded or spot-welded fleece, an active fleece or a foam fleece. It is also possible to use a combination of these materials. The weight of the fleece is preferably in the range of 10-180 g / m 2 .

Durch den Aufbau des Vliesverbundes aus den mehreren Schichten, die miteinander verklebt sind, werden die Nachteile der bisher bekannten Einlagetypen vermieden. Die eingesetzten Monofile, die den Sprung ergeben, sind durch das Verkleben fest fixiert, und die Enden dieser Monofile können im konfektionierten Teil nicht mehr wandern. Damit mit zugleich ein Durchstechen durch den Oberstoff verhindert. Ebenso kann sicher vermieden werden, daß Einschnürungen im Vlies entstehen, die sich durch den Oberstoff hindurch abzeichnen. By building up the fleece composite from the several Layers that are glued together become the Disadvantages of the previously known insert types avoided. The used monofilaments, which result in the jump, are by the Gluing firmly fixed, and the ends of these monofilaments can no longer hike in the assembled part. With that at the same time prevents piercing through the outer fabric. It can also be safely avoided that constrictions in the Fleece are created that extend through the outer fabric emerge.

Außerdem ist es auf einfache und kostengünstige Art und Weise möglich, einen Vliesverbund als Versteifungseinlage mit einer weichen und voluminösen Oberfläche herzustellen, die in der Konfektion sehr einfach zu verarbeiten ist. Das zeit- und kostenintensive Aufbringen von zusätzlichen Versteifungseinlagen in der Konfektion kann somit entfallen.It is also simple and inexpensive possible to use a fleece composite as a stiffening insert with a to produce soft and voluminous surface that in the Confection is very easy to process. That time and costly application of additional Stiffening inserts in the assembly can therefore be omitted.

Die Stärke und das Volumen des auf das Gewebe oder Gewirke aufgebrachten Vlieses ist nahezu beliebig variierbar, ohne daß Einschnürungen im Vlies auftreten, wie dies bei dem bekannten Verbund der Fall war. Weiterhin muß erfindungsgemäß kein Tierhaar mehr eingesetzt werden, so daß die damit verbundenen Nachteile nicht mehr auftreten. Insbesondere entfällt somit die zeitaufwendige Reinigung von Tierhaaren und die allergene Belastung des Personals, die mit diesen Haaren in Berührung gelangen.The strength and volume of the on the woven or knitted fabric applied fleece can be varied almost without any that constrictions occur in the fleece, as is the case with the known association was the case. Furthermore must According to the invention, animal hair is no longer used, so that the associated disadvantages no longer occur. In particular, the time-consuming cleaning of Animal hair and the allergenic burden on staff associated with get in touch with that hair.

Schließlich kann bei dem Einsatz von Monofilen im Schuß auch auf die Verwendung von Coregarnen verzichtet werden, so daß hierdurch der gesamte kostenintensive Prozeß der diesbezüglichen Garnerzeugung für das Schußgarn entfällt.Finally, when using monofilaments in the weft, too to be used without core yarns, so that thereby the entire costly process of related yarn production for the weft yarn is omitted.

Es ist ebenfalls möglich, den erhaltenen Vliesverbund nach bekannten Verfahren mit Schmelzklebern direkt zu beschichten, beispielsweise in Rasterform, um so eine direkte Fixierung auf dem Oberstoff zu ermöglichen. Die Beschichtung mit Schmelzklebern kann nach bisher üblichen Verfahren erfolgen, wobei neben dem Einzelpunktverfahren auch das sogenannte Doppelpunktverfahren in Betracht kommt. Als Schmelzkleber werden hier die üblichen verwendet, wobei insbesondere Schmelzkleber auf Basis von Polyamiden insbesondere bevorzugt sind.It is also possible to replicate the nonwoven composite obtained to coat known processes directly with hot melt adhesives, for example in grid form, so as a direct fixation to allow on the outer fabric. The coating with Hotmelt gluing can be carried out according to conventional methods, in addition to the single-point method, the so-called Colon procedure comes into consideration. As a hot melt adhesive the usual ones are used here, in particular Hot melt adhesive based on polyamides is particularly preferred are.
