Description
Die Erfindung befaßt sich mit einem aufbügelbaren Einlagevliesstoff. Ferner wird ein Verfahren zur Herstellung des Einlagevliesstoffs angegeben.The invention is concerned with an iron-on interlining nonwoven. Furthermore, a method for Manufacture of the interlining nonwoven specified.
EP 0 390 579 B1 beschreibt ein steppgebundenes textiles Flächengebilde, welches eine Faservlieslage und im Abstand angeordnete Reiben von Stichen mit einem Reihenabstand von 2 bis 10/cm besitzt. Das Steppgarn macht 2 bis 20% des Gesamtgewichts des textilen Flächengebildes aus. Die Faserlage besteht aus gebundenen Fasern, und das textile Flächengebilde besitzt eine Dehnbarkeit in Stichrichtung von 10 bis 75%. Das dort beschriebene Herstellungsverfahren umfaßt das Steppen einer Faservlieslage mit einem elastischen Faden, welcher währenddessen um 10 bis 100% gestreckt ist. Es werden im Abstand angeordnete, parallele Reihen von Stichen gebildet. Danach wird die Spannung aufgehoben und erst anschließend die Schrumpfbehandlung vorgenommen.EP 0 390 579 B1 describes a quilted textile fabric, which is a nonwoven layer and spaced rubbing of stitches with a row spacing of 2 to 10 / cm. The quilting yarn makes 2 to 20% of the total weight of the textile fabric. The fiber layer is there from bonded fibers, and the textile fabric has one Stretchability in the stitch direction from 10 to 75%. The manufacturing process described there includes quilting a nonwoven layer with an elastic one Thread that is stretched by 10 to 100% in the meantime.

Diese Abfolge der Verfahrensschritte führt zu einem Vliesstoff, welcher, abgearbeitet als aufbügelbarer Einlagevliesstoff, auf dem Oberstoff im Doppelfixierbereich eine nachteilige Oberflächenunruhe zeigen würde. Die Unruhe tritt auch auf beim Schrägziehen des mit dem Einlagevliesstoff fixierten Oberstoffs. Mit dem beschriebenen Verfahren sind zudem leichte Vliesstoffgewichte von 10 bis 40 g/m2 auf einer Kettwirkmaschine nur schwierig darstellbar, weil die Spannungen in Kettrichtung im Zusammenhang mit dem nur leicht gebundenen und leicht zerstörbaren Vliesstoff nur schwer zu kontrollieren sind. This sequence of process steps leads to a nonwoven fabric which, processed as an iron-on interlining nonwoven fabric, would show a disadvantageous surface unevenness on the outer fabric in the double-fixing area. The restlessness also occurs when the outer fabric fixed with the interlining nonwoven fabric is pulled diagonally. With the described method, light nonwoven fabric weights of 10 to 40 g / m 2 are also difficult to produce on a warp knitting machine because the tensions in the warp direction in connection with the only slightly bound and easily destructible nonwoven fabric are difficult to control.
Aufgabe der Erfindung ist es, einen elastischen, mittels Haftmasse aufbügelbaren Einlage-Vliesverbundstoff anzugeben, der leicht ist, einen runden, flachen und weichen Griff mit perfekter Oberflächenglätte aufweist und der waschund chemischreinigungs-beständig ist. Ferner soll ein Verfahren zur Herstellung dieses Einlagevliesverbundstoffs angegeben werden.The object of the invention is an elastic, iron-on by means of adhesive Insert nonwoven composite that is light, a round, flat and soft grip with perfect surface smoothness and the washable is resistant to dry cleaning. Furthermore, a method of manufacture is said to this interlining nonwoven composite can be specified.
Die Lösung dieser Aufgabe besteht in einem Einlagevliesverbundstoff, gemäß Anspruch 1 und einem Verfahren gemäß Anspruch 11. Vorteilhafte Ausgestaltungen werden jeweils in den Unteransprüchen angegeben.The solution to this problem is an interlining nonwoven composite, according to claim 1 and a method according to claim 11. Advantageous configurations are specified in the subclaims.
Der Einlagevliesverbundstoff ist mit aufgebrachter Haftmasse aufbügelbar ausgerüstet und enthält einen 10 bis 40 g/m2 schweren Vliesstoff, welcher eine elastische Kettverstärkung aufweist. Diese enthält 5 bis 25 g/m2 texturierte Kettfäden mit einer Primärdehnung von 10 bis 35%, einem Gesamttiter von 30 bis 120 dtex und einer Fadenzahl von 3 bis 25/inch (1,8 bis 9,84/cm). Der Verbundstoff weist in Längsrichtung eine Dehnung von 50 bis 120% auf. Das Gewichtsverhältnis Kettfäden:Vliesstoff beträgt 1:3 bis 3:1.The interlining nonwoven composite is equipped with an applied adhesive that can be ironed on and contains a 10 to 40 g / m 2 heavy nonwoven which has an elastic warp reinforcement. This contains 5 to 25 g / m 2 of textured warp threads with a primary elongation of 10 to 35%, a total titer of 30 to 120 dtex and a thread count of 3 to 25 / inch (1.8 to 9.84 / cm). The composite has an elongation of 50 to 120% in the longitudinal direction. The weight ratio of warp threads: nonwoven is 1: 3 to 3: 1.
Das Herstellungsverfahren für den Einlagevliesverbundstoff wird in einer Kettwirkmaschine mit Vliesstoffeintrag durchgeführt.. Der Vliesstoff wird mit den texturierten Kett-Filamenten verstärkt und der entstehende Verbund danach thermofixiert sowie mit einem Schmelzkleber versehen. Dabei wird der Vliesverbundstoff nach dem Eintrag der Kettfäden, jedoch vor der Thermofixierung, spannungslos einem vollständigen Schrumpfprozeß unterzogen, wonach dessen Enddehnung in Längsrichtung 50 bis 120% beträgt.The manufacturing process for the interlining nonwoven composite is described in one Warp knitting machine carried out with nonwoven fabric entry the textured warp filaments reinforced and the resulting composite then heat set and provided with a hot melt adhesive. The Non-woven composite after the entry of the warp threads, but before the Heat-setting, subjected to a complete shrinking process without tension, after which its final elongation in the longitudinal direction is 50 to 120%.
Es war nicht zu erwarten, daß der anfangs durch die Kettverstärkung relativ starre und im entspannten Zustand elastische Vliesstoff nach dem Schrumpfprozeß einen Einlagevliesverbundstoff ergibt, welcher nach der Fixierung auf einen Oberstoff mittels Schmelzkleber eine hervorragende Oberflächenglätte auch bei Doppelfixierung und Dämpfen, ergibt. Auch das Schrägziehen läßt, im Gegensatz zu allen kettverstärkten Einlagevliesstoffen des Standes der Technik, keine Oberflächenunruhe erkennen. Dies ist vor allem deshalb überraschend, weil die Kettfäden relativ dick sind.It was not expected to be relative initially due to the warp reinforcement rigid and in the relaxed state elastic nonwoven fabric after the shrinking process an interlining nonwoven composite material, which after fixation an outer fabric with hot melt adhesive excellent surface smoothness also with double fixation and steaming. Also pulling diagonally, in Contrary to all warp-reinforced interlining nonwovens of the prior art Technology, no surface irregularity. This is mainly because of that surprising because the warp threads are relatively thick.
Vor der Schrumpfung weist der Verbundstoff eine Längsdehnung zwischen 15 und 35% auf, danach zwischen 50 und 120%.Before shrinking, the composite has an elongation between 15 and 35%, then between 50 and 120%.
Als besonders geeignet für die Erfindung erwiesen sich Kettfäden aus Nylon 6 oder Nylon 66, weil diese eine besondere Weichelastizität erzeugen.Warp threads made of nylon 6 have proven to be particularly suitable for the invention or nylon 66, because they create a special soft elasticity.
Einen besonders guten Warenausfall erhält man mit Seite/Seite-Bikomponentenfilamenten mit Nylon 6- oder 66- einerseits und Polyester-Komponente andererseits.One gets a particularly good loss of goods with side / side bicomponent filaments with nylon 6- or 66- on the one hand and polyester component on the other hand.
Kettfäden aus Polyester werden bevorzugt, wenn man besonders farbstabile Einlagestoffe produzieren möchte.Warp threads made of polyester are preferred if you have particularly color-stable Wants to produce interlinings.
Zweckmäßig wird man als Grundlage weiche Vliesstoffe wählen. Bevorzugt sind punktverschweißte, fasergebundene Vliesstoffe.It is advisable to choose soft nonwovens as the basis. Prefers are spot-welded, fiber-bonded nonwovens.
Eine besondere Weichheit wird erzielt, wenn der Vliesstoff mit Wasserstrahlen verfestigt ist. Dabei können im Interesse einer besonders hohen inneren Festigkeit auch thermoplastische Bindefasern zusätzlich enthalten sein.A special softness is achieved when the nonwoven fabric is sprayed with water is solidified. In the interest of a particularly high internal strength thermoplastic binding fibers may also be included.
Alternativ sind auch verfestigende Bindemittel einsetzbar. Solchermaßen verhärtete Versionen eignen sich besonders für längselastische Bundeinlagen im Hosenbereich, welche die Anpassung an den Körperumfang erleichtern sollen.Alternatively, solidifying binders can also be used. So hardened Versions are particularly suitable for longitudinally elastic inlays in the Pants area, which should facilitate the adaptation to the body size.
Beim Herstellungsverfahren muß der Schrumfprozeß bezüglich des mit den Kettfäden versehen Vliesstoffs spannungslos durchgeführt werden, weil auf diese Weise die Elastizität des Verbundstoffs am besten erreicht wird. Die Schrumpfung kann mit Heißwasser erfolgen; bevorzugt ist jedoch Sattdampf, weil dabei wegen der geringeren Feuchtigkeitsaufnahme der Vliesverbundstoff am geringsten geschädigt wird und trotzdem der Schrumpfprozeß vollständig verläuft.In the manufacturing process, the shrinking process must be done with respect to the Warp threads provided non-woven fabric can be carried out without tension because on this is the best way to achieve the elasticity of the composite. The shrinkage can be done with hot water; however, saturated steam is preferred, because of the lower moisture absorption of the nonwoven composite is least harmed and yet the shrinking process runs completely.
Die folgenden Beispiele sollen das Wesen der Erfindung, ohne diese einzuschränken, näher verdeutlichen.The following examples are intended to illustrate the essence of the invention, without restricting it, clarify.
Auf eine Wirrmaschine wird ein Vlies gelegt mit 100% Polyamid 6-Fasern und einem Flächengewicht von 20 g/m2. Das Vlies wird auf einem Kalander, bestehend aus einer gravierten und einer glatten Walze, bei 200°C zu einem Vliesstoff verfestigt. Auf einer Raschelmaschine mit Vliesstoffeintrags-Möglichkeit wird dieser mit einem texturierten Bikomponenten-Kettfaden aus Polyamid 6/Polyester (Seite/Seite) durchwirkt, wobei der Titer 78 dtex beträgt. Die Fadenzahl beträgt 18 /inch (7,09/cm), bei gleichmäßigem Abstand zwischen den Fäden.A fleece with 100% polyamide 6 fibers and a basis weight of 20 g / m 2 is placed on a tangling machine. The nonwoven is consolidated on a calender, consisting of an engraved and a smooth roller, at 200 ° C to form a nonwoven. On a Raschel machine with the possibility to insert nonwovens, this is worked through with a textured bicomponent warp thread made of polyamide 6 / polyester (side / side), the titer being 78 dtex. The thread count is 18 / inch (7.09 / cm), with even spacing between the threads.
Der auf diese Weise hergestellte Verbundstoff wird spannungslos in einem Dämpfungsaggregat mit Sattdampf behandelt und aufgedockt. Dabei zeigt sich, daß der vorerst fast starre Faden mit einer ursprünglichen Längsdehnung von etwa 20% elastisch geworden ist und eine Dehnung von 80% aufweist.The composite material produced in this way becomes stress-free in one Damping unit treated with saturated steam and docked. It shows that the thread, which is almost rigid for the time being, has an original longitudinal extension of about 20% has become elastic and has an elongation of 80%.
In einem Spannrahmen wird der Verbundstoff bei 190°C einem Fixiervorgang unterzogen. Es folgt der punktförmige Auftrag eines Copolyamid-Schmelzklebers in einer Menge von 16 g/m2.The composite is subjected to a fixing process in a stenter at 190 ° C. The point-wise application of a copolyamide hot melt adhesive in an amount of 16 g / m 2 follows.
Beim Fixieren dieses Materials in einer Durchlaufpresse bei 140°C zeigt sich sowohl bei Einfach- als auch bei Doppelfixierung, vor und nach dem Abdämpfen, eine sehr glatte Oberfläche auf dem Oberstoff, ohne daß beim Verzug in Diagonalrichtung (Schrägzug) ein Unruhe auftritt.Fixing this material in a continuous press at 140 ° C shows up both with single and double fixation, before and after steaming, a very smooth surface on the outer fabric, without warping in An unrest occurs diagonally (diagonal pull).
Das Verfahren nach Beispiel 1 wird wiederholt mit dem Unterschied, daß ein nichttexturierter Polyamid 6-Kettfaden eingesetzt wird. Dessen Dehnung liegt bei etwa 15% in Längsrichtung und verändert sich nicht, wenn man die Ware einem Dämpfungsprozeß gemäß Beispiel 1 aussetzt. Das Material wird auf die dort beschriebene Art weiterbehandelt.The procedure of Example 1 is repeated with the difference that a non-textured polyamide 6 warp thread is used. Whose stretch is there at about 15% lengthways and does not change when you look at the goods exposed to a damping process according to Example 1. The material is on the treated there described type.
Bei Einfachfixierung ohne Dämpfung zeigt dieser Verbundstoff zwar eine ähnliche Oberflächenruhe wie in Beispiel 1, jedoch bewirken Doppelfixierung und vor allem Schrägzug eine deutliche Verschlechterung der gewünschten Oberflächenglätte. Der Griff ist deutlich fester und untextiler.With simple fixation without damping, this composite shows a similar one Surface calm as in Example 1, but double fixation and especially diagonal pull a significant deterioration in the desired surface smoothness. The handle is much firmer and less textile.
