Abstract

A fixing liner, made up of a textile liner web (1), which is coated on one side with double-layer adhesive mass points, which are made up of lower points, facing the liner web, and upper points (2, 3); arranged on top of them, the lower points (2) being made up of a powdery mixture of 25 to 90% by weight of an epoxide resin having an epoxide equivalent weight of 500 to 4000 mVal/kg, 10 to 75% by weight of an acid terminated polyamide, a polyester, a polyurethane and/or a vinyl copolymer having carboxyl, anhydro, hydroxy, and/or amido side groups and having a melt flow index (MFI) of 40 to 120 g/10 min measured at 160° C. and 2.16 kg, and 0 to 20% by weight of a hardener as well as the auxiliary and filler materials that are customarily used to produce a paste, the upper points (3) being composed of acid-terminated polyamides and/or copolyesters, and the weight ratio of the masses, obtained in the lower and upper points (2, 3), being 1:0.5 to 1:5.

Description

Die Erfindung betrifft eine Fixiereinlage, bestehend aus einer textilen Einlagebahn, die auf einer Seite mit doppelschichtigen Haftmassenpunkten beschichtet ist, die aus der Einlagebahn zugewandten Unter- und darüber angeordneten Oberpunkten besteht.The invention relates to a fixing insert, consisting of a textile Einlagebahn, on one side with double-layer adhesive mass points is coated, from the insert track facing lower and above arranged upper points exists.

Aus dem Dokument EP-A 0 940 461 ist eine vernetzbare Schmelzklebemasse für die Beschichtung und/oder Laminierung von Flächengebilden bekannt, bei der eine Vernetzungskomponente in eine Polyolefin-Matrix eingebunden ist und die reaktionsfähigen Komponenten erst in der Schmelze unter Vernetzung reagieren. Als Vernetzungskomponenten werden Isocyanate oder Epoxide mit Molmassen zwischen 2000 und 6000 Gramm je Mol angegeben. Die eigentliche Schmelzklebemasse soll dabei aus aminoterminierten Copolyamid oder Copolyester bestehen, welche sowohl im Unter- als auch im Oberpunkt eingesetzt werden. Nachteilig an dieser Lösung ist, dass zum einen die Vernetzungskomponente erst aufwendig in eine vor Feuchtigkeit schützende Polyolefin-Matrix eingebunden werden muss und dass die aminoterminierten Copolyamide stark zur Vergilbung neigen.From the document EP-A 0 940 461 is a crosslinkable Hotmelt adhesive for the coating and / or lamination of Fabrics known in which a crosslinking component in a Polyolefin matrix is incorporated and the reactive components only react in the melt with crosslinking. When Crosslinking components are isocyanates or epoxides with molecular weights stated between 2000 and 6000 grams per mole. The real one Hot-melt adhesive is intended to consist of amino-terminated copolyamide or Copolyesters exist, which both in the lower and in the upper point be used. The disadvantage of this solution is that on the one hand the Crosslinking component only consuming in a moisture-protecting Polyolefin matrix must be included and that the amino-terminated Copolyamides are prone to yellowing.

Weiterhin sind aus dem Dokument US 5,677,038 zweischichtige Schmelzklebemassen bekannt, deren Unterpunkt aus einem pastenförmig aufgebrachten Copolyamid oder Copolyester besteht und deren Oberpunkt aus einem Gemisch aus 0 bis 25 Gew.% eines Copolyamids, 50 bis 95 Gew.% eines Copolyesters und 5 bis 25 Gew.% eines Epoxids besteht. Als Trennkräfte für die mit diesem Schmelzklebesystem verbundenen textilen Materialien werden Wert unter 10 N/5 cm angegeben, die sich nach einer Wäsche weiter reduzieren. Neben den genannten Dokumenten sind weitere doppelschichtige Haftmassen aus den Dokumenten DE-A 22 14 236, DE-A 22 31 723, DE-A 25 36 911 und DE- A 32 30 579 bekannt. Durch die Verwendung von relativ leichten Vliesstoffen, d.h. solchen mit einem geringen Flächengewicht werden zwar sehr weiche Laminate erhalten, allerdings weisen die Vliesstoffe den Nachteil auf, dass sie bezüglich der Rückvernietung der Schmelzklebemassen empfindlich sind. Unter Rückvemietung wird dabei eine unerwünschte Verklebung zwischen zwei Einlagestoffen verstanden, die eintreten kann, wenn der mit der Haftpunktmasse beschichtete Einlagebahn, im weiteren Text als Fixiereinlage bezeichnet, im Innensandwich―Fixierungsverfahren mit dem Oberstoff verbunden wird. Das Innensandwich besteht dabei aus der Schichtenfolge Oberstoff, beschichteter Einlagebahn sowie beschichteter Einlagebahn und Oberstoff, d.h., dass die unbeschichteten Seiten der Einlagebahnen aneinander liegen. Zwar wurde die Beschichtungsmenge, die pro Quadratmeter Einlagebahn aufgebracht wird von früher 18 - 25 g/m2 auf 7 - 15 g/m2 reduziert und sollten im Hinblick auf die Atmungsfähigkeit des textilen Laminats noch weiter reduziert werden. Gleichzeitig steigen aber die Anforderungen an die Haftung und Beständigkeit des Laminats. Furthermore, US Pat. No. 5,677,038 discloses two-layer hotmelt adhesives whose subpoint consists of a paste-like copolyamide or copolyester and whose top point consists of a mixture of 0 to 25% by weight of a copolyamide, 50 to 95% by weight of a copolyester and 5 to 25% by weight .% of an epoxide. As separating forces for the textile materials associated with this hot-melt adhesive system, values of less than 10 N / 5 cm are specified, which are further reduced after washing. In addition to the cited documents, further double-layered adhesive compositions are known from the documents DE-A 22 14 236, DE-A 22 31 723, DE-A 25 36 911 and DE-A 32 30 579. By using relatively lightweight nonwovens, ie those having a low basis weight, very soft laminates are obtained, but the nonwoven fabrics have the disadvantage that they are sensitive to the back riveting of the hotmelt adhesives. Reclaimed here is an undesirable bond between two interlining understood, which can occur when the adhesive coated with the adhesive layer insert web, hereinafter referred to as a fuser, is connected in Innensandwich-fixing method with the outer fabric. The inner sandwich consists of the layer sequence outer fabric, coated insert sheet and coated insert sheet and outer fabric, ie, that the uncoated sides of the inserts lie against each other. Although the amount of coating applied per square meter of insert web was reduced from previously 18-25 g / m 2 to 7-15 g / m 2 and should be further reduced in view of the breathability of the textile laminate. At the same time, however, the demands on the adhesion and durability of the laminate increase.

Anforderungen an die Haftung und Beständigkeit des Laminats. Insbesondere im Hinblick auf die Pflegeeigenschaften eines textilen Laminats besteht die Forderung, dass dieses auch mehrere Wäschen bei Waschtemperaturen bis 60°C übersteht.Requirements for the adhesion and durability of the laminate. Especially with regard to the care properties of a textile laminate There is a demand that this also several washes at Washing temperatures up to 60 ° C.

Die Erfindung hat sich die Aufgabe gestellt, eine Fixiereinlage anzugeben, die deutlich erhöhte Haft- und Trennkräfte bei einer gleichzeitig sehr geringen Rückvernietung zeigt.The object of the invention has been found to provide a fixation, the significantly increased adhesion and separation forces at the same time a very small Rear riveting shows.

Mit den erfindungsgemäßen Fixiereinlagen werden Trennkraftwerte erhalten, die 50 oder insbesondere nach Wäschen bei Temperaturen von 60°C mehr als 100 % über denen von mit bekannten doppelschichtigen Haftpunktmassen hergestellten Fixiereinlagen liegen.
