Beschreibung description
Technisches Gebiet Technical area
Die Erfindung betrifft eine Einlage zur Verwendung als Stickerei-Fixiereinlage, bestehend aus einem textilen Trägermaterial, welches mit einer Haftmasse beschichtet ist, wobei die Haftmasse ein wasserlösliches, thermoplastisches Polymer aufweist. The invention relates to an insert for use as an embroidery fixation insert, consisting of a textile carrier material which is coated with an adhesive mass, wherein the adhesive composition comprises a water-soluble, thermoplastic polymer.
Stand der Technik Wasserlösliche Haftmassen für wasserlösliche Stickerei-Fixiereinlagen der eingangs genannten Art sind bereits aus der DE 100 32 769 A1 bekannt. Des Weiteren sind fixierbare wasserlösliche Haftmassen bekannt, die auf PRIOR ART Water-soluble adhesive compositions for water-soluble embroidery fixation liners of the type mentioned in the introduction are already known from DE 100 32 769 A1. Furthermore, fixable water-soluble adhesive compositions are known
Einlagestoffen, insbesondere auf Vliesstoffen, dem temporären Festhalten von textilen Lagen dienen. Einlagestoffen, especially on nonwovens, the temporary retention of textile layers serve.
Dabei werden vor oder während der Verarbeitung Einlagestoffe bzw. Vliesstoffe mit einer als Oberstoff ausgestalteten textilen Lage in einer Fixierpresse zusammenlaminiert. Im Anschluss daran werden verstärkte und unverstärkte Teile zusammengefügt, vernäht und bei Bedarf durch Formbügeln geformt. In this case, before or during processing, lining fabrics or nonwovens are laminated together with a textile layer configured as an outer material in a fixing press. Subsequently, reinforced and unreinforced parts are joined together, sewn and shaped if necessary by shaping.
BESTÄTIGUNGSKOPIE Nach einem anschließenden Waschprozess wird die Haftmasse ausgewaschen. Hierdurch werden zusammengefügte Lagen wieder gelöst und somit Kleidungsstücke flexibler und weicher. Auch unterschiedlich krumpfende Stoffe können so zusammengefügt werden, ohne dass eine Blasenbildung nach Pflegebehandlungen auftritt. CONFIRMATION COPY After a subsequent washing process, the adhesive is washed out. As a result, joined layers are released again and thus garments more flexible and softer. Even different shrinking substances can be joined together without blistering after care treatments occurs.
Die aus der DE 100 32 769 A1 bekannten Haftmassen werden durch The adhesive compositions known from DE 100 32 769 A1 are known

Die aus der DE 100 32 769 A1 bekannten Polymere für Haftmassen auf Basis von (Co-)Polyamiden, Polyvinylalkoholen und / oder (Co-)Polyestern sind in Form einer wässrigen Dispersion nicht durch ein Rotationssiebdruckverfahren auf wasserlösliche Vliesstoffe aufdruckbar, da das Wasser in der Haftmasse zu punktuellen Auflösung des wasserlöslichen Vliesstoffes führt. Angelöste oder bedruckte Stellen des wasserlöslichen Vliesstoffs führen zu einer unansehnlichen, unruhigen Oberfläche des mit Haftmasse beschichteten Vliesstoffes. The polymers known from DE 100 32 769 A1 for adhesive compositions based on (co) polyamides, polyvinyl alcohols and / or (co) polyesters can not be imprinted on water-soluble nonwovens in the form of an aqueous dispersion by a rotary screen printing method, since the water in the Adhesive mass leads to selective dissolution of the water-soluble nonwoven fabric. Triggered or printed areas of the water soluble nonwoven result in an unsightly, rough surface of the adhesive coated nonwoven fabric.
Diese Unruhe überträgt sich auf die durch die Einlage fixierte textile Lage. Die genannte Unruhe der Oberfläche führt zu einer negativen Beeinträchtigung des optischen Erscheinungsbildes der fertigen Ware. This restlessness is transferred to the textile layer fixed by the insert. The aforementioned restlessness of the surface leads to a negative impairment of the visual appearance of the finished product.
Angelöste Stellen oder Löcher im Vliesstoff sind nicht akzeptabel und schließen eine Verwendung des Materials für die Bekleidung oder für Stickereien aus. Darstellung der Erfindung Marked spots or holes in the nonwoven fabric are unacceptable and preclude use of the material for clothing or embroidery. Presentation of the invention
Der Erfindung liegt daher die Aufgabe zu Grunde, die aus dem Stand der Technik bekannten Haftmassen derart auszugestalten und weiterzubilden, dass sie problemlos für wasserlösliche Einlagen, insbesondere für Vliesstoffe, verwendet werden können. The invention is therefore based on the object to design the adhesive compositions known from the prior art in such a way and further that they can be easily used for water-soluble deposits, especially for nonwovens.
Die vorliegende Erfindung löst die zuvor genannte Aufgabe durch die Merkmale des Patentanspruchs 1. The present invention achieves the aforementioned object by the features of patent claim 1.
Danach ist die eingangs genannte Einlage dadurch gekennzeichnet, dass die Haftmasse als wässrige Polymerdispersion und/ oder als Polymerlösung ausgestaltet ist. Thereafter, the aforementioned insert is characterized in that the adhesive composition is designed as an aqueous polymer dispersion and / or as a polymer solution.
Überraschend wurde gefunden, dass eine ausreichend hoch konzentrierte wässrige Polymerdispersion und/ oder Polymerlösung auf leicht Surprisingly, it has been found that a sufficiently highly concentrated aqueous polymer dispersion and / or polymer solution are readily dissolved
wasserlöslichen Trägermaterialien, insbesondere Vliesstoffen, ohne die oben genannten negativen Effekte aufgedruckt werden kann. Erfindungsgemäß ist erkannt worden, dass ein wässriges System auf kaltwasserlöslichen water-soluble carrier materials, in particular nonwovens, without the negative effects mentioned above can be printed. According to the invention, it has been recognized that an aqueous system is soluble in cold water
Vliesstoffen aufdruckbar ist. Dabei wird unter Kaltwasser Wasser einer Nonwovens is imprintable. This is under cold water, a water
Temperatur bis zu 40° C verstanden. Temperature up to 40 ° C understood.
Folglich ist die eingangs genannte Aufgabe gelöst. Consequently, the object mentioned above is achieved.
Beim Bedrucken kann eine Schablonengröße von CP 5 - CP 250 verwendet werden. When printing, a stencil size of CP 5 - CP 250 can be used.
Die Haftmasse könnte einen Feststoffgehalt von mehr als 50 % aufweisen. Durch diese oder eine höhere Konzentration wird ein Aufquellen des The adhesive mass could have a solids content of more than 50%. This or a higher concentration swells the
kaltwasserlöslichen Trägermaterials vermieden. Die Haftmasse könnte Vinylpyrrolidone oder modifizierte Vinylpyrrolidone aufweisen. Zur Herstellung der wässrigen Polymerdispersion und/ oder cold water-soluble carrier material avoided. The adhesive composition could have vinylpyrrolidone or modified vinylpyrrolidone. For the preparation of the aqueous polymer dispersion and / or
Polymerlösung haben sich insbesondere Polyvinylpyrrplidon und Polymer solution have in particular polyvinylpyrrolidone and
Copolymerisate als geeignet erwiesen. Vinylpyrrolidone sind gut Copolymers proved to be suitable. Vinyl pyrrolidones are good
kaltwasserlöslich, sind aber stark hygroskopisch und werden mit steigender Luftfeuchte klebrig. Vinylpyrrolidone mit Polyvinylacetatanteilen sind weniger hygroskopisch bei Raumtemperatur als nicht modifizierte Vinylpyrrolidone. Daher verkleben die beschichteten Einlagen nicht im aufgerollten Zustand. cold water soluble, but are highly hygroscopic and become sticky with increasing humidity. Vinylpyrrolidones with polyvinyl acetate moieties are less hygroscopic at room temperature than unmodified vinylpyrrolidones. Therefore, the coated deposits do not stick when rolled up.
Die Haftmasse könnte Polyole oder Polyglykole aufweisen. Durch einen Zusatz von Polyolen und/ oder Polyglykolen kann der Schmelzbereich eines Polymers, insbesondere der Vinylpyrrolidone, geändert, insbesondere gesenkt, werden bzw. der Schmelzfluss des Polymers den jeweiligen Anwendungen angepasst werden. Die wasserlösliche Haftmasse wird durch Polyglykole weichgemacht. Bevorzugt wird Polyethylenglykol (PEG) als Weichmacher verwendet. The adhesive composition could comprise polyols or polyglycols. By adding polyols and / or polyglycols, the melting range of a polymer, in particular the vinylpyrrolidones, can be changed, in particular lowered, or the melt flow of the polymer can be adapted to the respective applications. The water-soluble adhesive is softened by polyglycols. Polyethylene glycol (PEG) is preferably used as plasticizer.
Besonders bevorzugt wird PEG 400 in einer Konzentration von 0 - 20%, besonders bevorzugt in einer Konzentration von 2 - 10% verwendet. Particular preference is given to using PEG 400 in a concentration of 0-20%, particularly preferably in a concentration of 2-10%.
Des Weiteren könnten der Haftmasse 0 - 10 Gewichts% an Druckhilfsmitteln, wie Dispergatoren oder Verdicker, beigemengt sein. In addition, the adhesive mass could be admixed with 0-10% by weight of printing auxiliaries, such as dispersants or thickeners.
Das textile Trägermaterial könnte wasserlöslich sein. Hierdurch kann das Trägermaterial aufgelöst werden. The textile carrier material could be water-soluble. As a result, the carrier material can be dissolved.
Das textile Trägermaterial könnte aus Polyvinylalkohol gefertigt sein. Der Polyvinylalkohol des Trägermaterials könnte durch eine Ethoxylierung der Polymeren oder durch eine Verseifung mit einem Verseifungsgrad von mehr als 95 % modifiziert sein. Modifizierte Polyvinylalkohole lösen sich gut in kaltem Wasser, nämlich Wasser mit einer Temperatur von 10 bis 40° C. Insbesondere könnte das textile Trägermaterial als Vliesstoff ausgestaltet sein. Der Vliesstoff könnte ein Flächengewicht von 20 bis 120 g/m2 aufweisen. The textile carrier material could be made of polyvinyl alcohol. The polyvinyl alcohol of the carrier material could be modified by ethoxylation of the polymers or by saponification with a degree of saponification greater than 95%. Modified polyvinyl alcohols dissolve well in cold water, namely water at a temperature of 10 to 40 ° C. In particular the textile carrier material could be designed as a nonwoven fabric. The nonwoven fabric could have a basis weight of 20 to 120 g / m 2 .
Sowohl das textile Trägermaterial als auch die Haftmasse könnten bei Both the textile carrier material and the adhesive composition could at
Temperaturen von 10 bis 40° C wasserlöslich sein. Temperatures of 10 to 40 ° C be water-soluble.
Die eingangs genannte Aufgabe wird auch durch eine Haftmasse zur The object mentioned above is also characterized by an adhesive mass

wasserlöslichen Trägermaterialien. Auch auf nicht wasserlöslichen, textilen Trägermaterialien ließen sich gut fixierbare Beschichtungen aus der genannten Haftmasse aufbringen, die sich nach der Verarbeitung leicht auswaschen ließen. Vor diesem Hintergrund könnte der Feststoffgehalt der Haftmasse geringer als 50 % sein. water-soluble carrier materials. Also on non-water-soluble, textile support materials could be applied well fixable coatings of said adhesive, which could be washed out easily after processing. Against this background, the solids content of the adhesive mass could be less than 50%.
Die hier beschriebenen Einlagen sind fixierbar, das heisst, sie können in einem thermischen Prozess mit textilen Oberstoffen beliebiger Art problemlos verbunden werden. Der thermische Prozess, nämlich die Fixierung oder Laminierung, wird bei Temperaturen von 80 bis 140° C durchgeführt. The deposits described here are fixable, that is, they can be easily connected in a thermal process with textile materials of any kind. The thermal process, namely fixation or lamination, is carried out at temperatures of 80 to 140 ° C.
Die hier beschriebenen Haftmassen sind bevorzugt für Einlagevliesstoffe, insbesondere für wasserlösliche Einlage- und/ oder Stickereivliesstoffe verwendbar. The adhesive compositions described here are preferably usable for nonwoven insert fabrics, in particular for water-soluble inlay and / or embroidery nonwovens.
Ein Verfahren zur Herstellung einer Einlage der hier beschriebenen Art könnte die folgenden Schritte umfassen: Bereitstellen eines textilen Trägermaterials und Beschichten des textilen Trägermaterials mit einer Haftmasse, welche eine wässrige Polymerdispersion und/ oder eine Polymerlösung aufweist. Hierdurch ist eine Einlage zunächst als Zwischenprodukt herstellbar, die mit einer wässrigen Polymerdispersion und / oder einer Polymerlösung beschichtet ist.

Ausführungsbeispiel 2: Embodiment 2:
Als Trägermaterial für eine Stickerei-Fixiereinlage wurde ein thermisch gebundener, aus kaltwasserlöslichen Polyvinylalkohol-(PVAL)-Stapelfasern hergestellter Vliesstoff mit einem Flächengewicht von ca. 40 g/m2 eingesetzt. The carrier material for an embroidery fixation insert was a thermally bonded nonwoven fabric produced from cold-water-soluble polyvinyl alcohol (PVAL) staple fibers having a weight per unit area of about 40 g / m 2 .
Die Polyvinylalkoholfasern-Stapelfasern wurden in einem Gel-Spinnverfahren hergestellt und wiesen eine Festigkeit von 4 g/denier auf. Dieser Vliesstoff wurde mit einer Haftmasse, nämlich einer Dispersion bzw. Lösung, mit 60% Feststoffgehalt bedruckt. Die Haftmasse bestand aus 600 g/l Luvitec VA 64, 45 g/l PEG 400 und 5 g/l einer Mischung aus Dispergatoren, Verdickern und Pastenlaufhilfsmitteln. Die Bedruckung erfolgte mittels einer Rotationssiebdrucktechnik. Es wurde mit einer Druckschablone CP 52, was einer offenen Fläche von 15 % entspricht, eine Beschichtung aus Haftmasse von 15 g/m2 aufgetragen. Die Trocknung erfolgte bei 145°C. Das Bedrucken mit den genannten Haftmassen bereitete überraschend keine Probleme. Nach dem Trocknen war auch keine Verklebung der Lagen zu beobachten. The polyvinyl alcohol staple fibers were prepared in a gel spinning process and had a strength of 4 g / denier. This nonwoven fabric was printed with an adhesive mass, namely a dispersion or solution, with 60% solids content. The adhesive consisted of 600 g / l Luvitec VA 64, 45 g / l PEG 400 and 5 g / l of a mixture of dispersants, thickeners and paste flow aids. The printing was carried out by means of a rotary screen printing technique. A coating of adhesive mass of 15 g / m 2 was applied using a CP 52 printing stencil, which corresponds to an open area of 15%. The drying took place at 145.degree. The printing with the above adhesives prepared surprisingly no problems. After drying, no sticking of the layers was observed.

In the following Table 2, adhesion values are shown which result when an insert of the type described here is connected to a shirt poplin test fabric.
Tabelle 2 Das in der Tabelle 2 genannte modifizierte (mod.) PA (Polyamid) entspricht dem Polyamid gemäß Beispiel 1 aus der DE 100 32 769 A1. VA steht für Vinylacetat, wobei das Produkte Luvitec VA 64 verwendet wird. PEG steht für Polyethylenglykol. Vorteile: Table 2 The modified (mod.) PA (polyamide) mentioned in table 2 corresponds to the polyamide according to example 1 from DE 100 32 769 A1. VA stands for vinyl acetate, using the product Luvitec VA 64. PEG stands for polyethylene glycol. Advantages:
Beim Ansintern von kaltwasserlöslichem Polymerpulver auf Co-Polyester-Basis (Typ Schättifix 699) waren die Sinterbedingungen mit mehr als 150°C an der Grenze des Schrumpfbeginns des Trägermaterials. Beim Ansintern trat ein starker Breitenverlust auf. When sintering cold-water-soluble polymer powder based on co-polyester (type Schättifix 699), the sintering conditions of more than 150 ° C. were at the limit of the shrinkage start of the support material. During sintering, a large width loss occurred.
Dies ist mit der erfindungsgemäßen Mischung und dem hier beschriebenen Verfahren nicht mehr problematisch. Trocknungstemperaturen von unter 150°C sind gut realisierbar. Das Ansintern aufgedruckter Punkte ist sehr gut. This is no longer problematic with the mixture according to the invention and the method described here. Drying temperatures of less than 150 ° C are easy to implement. The sintering of printed dots is very good.
Das aufwändige Verfahren, einen Spinnvliesstoff aus wasserlöslichen The elaborate process, a spunbonded fabric made of water-soluble
Polymeren separat zu erspinnen, und diese dann mit dem wasserlöslichen Vliesstoff zu laminieren, wird durch das hier beschriebene Verfahren wesentlich vereinfacht. Spinning polymers separately and then laminating them with the water-soluble nonwoven fabric is greatly simplified by the process described herein.
Man kann Polymermischungen der oben genannten Art auch You can also polymer blends of the above type
zusammenschmelzen. Hierbei tritt eine bräunliche Verfärbung auf. Diese Polymermischung kann als Hot-Melt oder im vermahlenen Zustand als fuse together. This causes a brownish discoloration. This polymer mixture can be used as a hot-melt or in the ground state as
Puderpunkt aufgetragen werden. Dieser zusätzliche Arbeitsgang verteuert das Verfahren, wobei die Verfärbung eine ungewünschte Zusatzeigenschaft darstellt. Powder point to be applied. This additional operation makes the process more expensive, the discoloration representing an undesired additional property.
Das hier beschriebene Verfahren ist einfach realisierbar, da die Komponenten zusammengerührt werden können. Nach einer Entlüftung entsteht eine leicht weißliche Dispersion oder eine klare Lösung. Mit 1 - 3% Verdicker aus modifizierter Zellulose kann die notwendige Viskosität der Mischung zum Drucken eingestellt werden. Je nach Bedarf können noch weitere Druckhilfsmittel in geringen Mengen beigemengt werden. The method described here is easy to implement because the components can be stirred together. After venting creates a slightly whitish dispersion or a clear solution. With 1 - 3% modified cellulosic thickener, the necessary viscosity of the mixture can be achieved Print to be set. Depending on requirements, further printing auxiliaries can be added in small amounts.
Die druckfähige Haftmasse soll einen Feststoffgehalt von mehr als 50 % haben, um gut kaltwasserlösliche Trägermaterialien bedrucken zu können. The printable adhesive mass should have a solids content of more than 50% in order to print good cold water-soluble carrier materials can.
Feststoffgehälter von mehr als 75% liefern eine hochviskose Mischung, die nur relativ schwierig zum Drucken verwendet werden kann. Auf nicht wasserlösliche Trägermaterialien sind auch Mischungen mit niedrigeren Feststoffgehältern aufdruckbar.  Solids greater than 75% provide a high viscosity blend that is relatively difficult to use for printing. It is also possible to print on mixtures with lower solids contents on non-water-soluble carrier materials.
