Abstract

Adhesive lining comprises a textile strip (1) coated on one side with two-layer spots of adhesive in which the bottom layer (2) comprises a binder paste comprising 50-95 wt.% of an acrylate binder dispersion, 5-50 wt.% of an epoxy resin or a glycidyl-functional acrylate copolymer and 0-20 wt.% hardener and the top layer (3) comprises a copolyamide, copolyester, thermoplastic polyurethane or polyolefin. The weight ratio of bottom layer to top layer is 1:0.5-5. Adhesive lining comprises a textile strip (1) coated on one side with two-layer spots of adhesive in which the bottom layer (2) comprises a binder paste comprising 50-95 wt.% of an acrylate binder dispersion with a glass transition temperature below room temperature, 5-50 wt.% of an epoxy resin with an epoxide equivalent weight of 500-4000 meq/kg or a glycidyl-functional acrylate copolymer and 0-20 wt.% hardener and the top layer (3) comprises a copolyamide, copolyester, thermoplastic polyurethane or polyolefin. The weight ratio of bottom layer to top layer is 1:0.5-5. An Independent claim is also included for production of the lining by applying the binder paste to the textile strip in discrete spots, dusting the wet spots with 50-500 wt.% of the top layer material in powder form, removing excess powder, drying the spots, and sintering the powder so that the lining can be handled and transported.

Description

Die Erfindung betrifft eine Fixiereinlage, bestehend aus einer textilen Einlagebahn (wie z.B. Vliesstoffe, Gewebe, Gewirke), 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 Interlining (such as nonwovens, woven fabrics, knitted fabrics) on one side double-layer adhesive mass points is coated, which from the Interlining facing lower and upper points arranged above consists.

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. Document EP-A 0 940 461 describes a crosslinkable one Hotmelt adhesive for the coating and / or lamination of Flat structures are known in which a crosslinking component into a Polyolefin matrix is integrated and the reactive components only react in the melt with crosslinking. As networking components are isocyanates or epoxies with molecular weights between 2000 and 6000 Gram specified per mole. The actual hotmelt adhesive should do so consist of amino-terminated copolyamide or copolyester, which can be used both in the lower and in the upper point. Disadvantageous this solution is that on the one hand the networking component elaborately integrated in a moisture-protecting polyolefin matrix must be and that the amino-terminated copolyamides strongly Yellowing tend.

Das Dokument DE-A 195 10 316 beschreibt eine Schmelzklebemasse zum Beschichten von Flächengebilden, insbesondere Einlagestoffen, die eine Mischung aus thermoplastischen Schmelzkleber und Epoxid enthält, wobei der Epoxidanteil 5 bis 25 Gew.-% beträgt. Diese Schmelzklebemasse wird als Einpunkt-Beschichtung eingesetzt, die Nachteile hinsichtlich des Durchschlagens der Schmelzklebemasse bei sehr dünnen Einlagestoffen besitzt.Document DE-A 195 10 316 describes a hot melt adhesive for Coating of flat structures, in particular interlinings, the one Mixture of thermoplastic hot melt adhesive and epoxy contains, wherein the epoxy content is 5 to 25% by weight. This hot melt adhesive is called Single-point coating used, the disadvantages in terms of Penetration of the hot-melt adhesive with very thin interlinings has.

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 Werte 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 Rückvernietung 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. Sie sollten im Hinblick auf die Weichheit des textilen Laminats jedoch noch weiter reduziert werden. Gleichzeitig wird bei hohen Anforderungen an die Haftung und Beständigkeit des Laminats mehr Wert auf den Griff gelegt. Insbesondere im Hinblick auf die Pflegeeigenschaften eines textilen Laminats besteht die Forderung, dass dieses auch mehrere Wäschen bei Waschtemperaturen bis 60°C übersteht.Furthermore, two-layer hotmelt adhesives are known from document US Pat. No. 5,677,038, the lower point of which consists of a pasty copolyamide or copolyester and the upper point of which 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 epoxy exists. Values below 10 N / 5 cm are given as separating forces for the textile materials connected with this hot-melt adhesive system, which are further reduced after washing. In addition to the documents mentioned, further double-layer adhesive compositions are known from 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 light nonwovens, ie those with a low basis weight, very soft laminates are obtained, but the nonwovens have the disadvantage that they are sensitive to the riveting back of the hotmelt adhesives. Back riveting is understood to mean an undesired gluing between two interlining materials, which can occur if the interlining sheet coated with the adhesive point mass, hereinafter referred to as a fixing interlining, is connected to the outer fabric in the inner sandwich fixing process. The inner sandwich consists of the layer sequence of outer fabric, coated insert sheet and coated insert sheet and outer fabric, that is to say that the uncoated sides of the insert sheets lie against one another. The amount of coating applied per square meter of interlining was reduced from 18-25 g / m 2 to 7-15 g / m 2 . However, they should be further reduced with regard to the softness of the textile laminate. At the same time, greater emphasis is placed on the handle when the laminate has to meet high adhesion and durability requirements. Particularly with regard to the care properties of a textile laminate, there is a requirement that it also withstand several washes at washing temperatures up to 60 ° C.

Zwar sind aus dem Dokument DE 100 27 957 Doppelpunktsysteme für die Beschichtung von Einlagestoffen bekannt, die durch die Verwendung von Epoxidharzen in den Unterpunkten eine verbesserte Haftung bei einer reduzierten Rückschlagneigung zeigen. Nachteilig hierbei ist jedoch, dass durch den Einsatz von teilkristallinen Thermoplasten in Kombination mit Epoxiden im Unterpunkt der Griff der Einlage negativ beeinflusst wird. Das heißt, dass der Griff fester wird.Although the document DE 100 27 957 colon systems for Coating of interlinings known through the use of Epoxy resins in the sub-items improved adhesion to a show reduced tendency to kickback. The disadvantage here, however, is that through the use of semi-crystalline thermoplastics in combination with Epoxides in the sub-point of the handle of the insert is negatively affected. The means that the handle becomes firmer.

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 is to provide a fixing insert which significantly increased adhesive and release forces with a very low at the same time Back riveting shows.

Erfindungsgemäß wird die Aufgabe durch eine Fixiereinlage, bestehend aus einer textilen Einlagebahn (1), die auf einer Seite mit doppelschichtigen Haftmassenpunkten beschichtet ist, die aus der Einlagebahn zugewandten Unter- und darüber angeordneten Oberpunkten (2,3) besteht, gelöst, bei der die Unterpunkte (2) entweder aus einer Binderpaste bestehen, die
50 bis 95 Gew.% einer Acrylatbinder-Dispersion mit einem Tg < Raumtemperatur und 5 bis 50 Gew.% eines Epoxidharzes mit einem Epoxidequivalentgewicht von 500 bis 4000 mVal/kg oder 50 bis 95 Gew.% einer Acrylatbinder-Dispersion mit einem Tg < Raumtemperatur und 5 bis 50 Gew.% eines Copolymeren aus Acrylaten und Monomeren mit Glycidyl-Seitengruppen
und 0 bis 20 Gew.% eines Härters sowie herkömmlichen zur Herstellung einer Paste eingesetzter Hilfs- und Zuschlagstoffen als Unterpunkt (2) enthält,
wobei die Oberpunkte (3) aus Copolyamiden und/oder Copolyestern und/oder thermoplastischen Polyurethanen und/oder Polyolefinen bestehen und
dass das Gewichtsverhältnis der in den Unter- und Oberpunkten (2,3) enthaltenen Massen 1:0,5 bis 1:5 beträgt. Mit den erfindungsgemäßen Fixiereinlagen werden Trennkraftwerte erhalten, die auch nach mehrern Wäschen bei Temperaturen von 60°C noch sehr gut sind. Überraschender Weise zeigen die erfindungsgemäßen Fixiereinlagen trotz der Verwendung von Komponenten in der Haftmasse (Unterpunkt) mit einem Glaspunkt Tg > 60°C, die normalerweise für den Einsatz im Einlagebereich wegen ihres sehr negativen (verhärtenden) Einflusses auf den Griff nicht in Frage kommen, keine Auswirkungen auf die haptischen Eigenschaften (Griff) der erfindungsgemäßen Fixiereinlage.According to the invention, the object is achieved by a fixing insert consisting of a textile interlining (1) which is coated on one side with double-layer adhesive mass points, which consists of lower and upper points (2, 3) arranged above the interlining, in which the Sub-items (2) either consist of a binder paste that

wherein the top points (3) consist of copolyamides and / or copolyesters and / or thermoplastic polyurethanes and / or polyolefins and
that the weight ratio of the masses contained in the lower and upper points (2,3) is 1: 0.5 to 1: 5. With the fixing inserts according to the invention, separation force values are obtained which are still very good even after several washes at temperatures of 60 ° C. In spite of the use of components in the adhesive (sub-point) with a glass point T g > 60 ° C., the fixing inserts according to the invention surprisingly show that are normally out of the question for use in the insert area because of their very negative (hardening) influence on the handle, no effects on the haptic properties (handle) of the fixing insert according to the invention.
