Definitions
- the present invention relates to a transfer paper and a method for transferring photocopies to textiles, such as in particular T-shirts.
- Such transfer papers carry a pressure-absorbing plastic layer which is transferred hot to the textile, the pressure being ironed onto the textile and, if appropriate, the paper being removed after a certain cooling time, after which plastic and pressure remain on the fabric. Since the photocopy is a positive print, a negative impression is created on the textile. If you want a positive image on the tissue, a negative impression must be made before transfer, e.g. in EP-05 22 898 A1 and DE-42 10 976 A1.
- the object of the present invention is therefore to create a transfer paper which can be used to produce positive prints directly and which furthermore have a plastic coating which ensures a higher brilliance of the image and into which a white pigment can be incorporated, in particular for printing on black textiles .
- the only solvent water used in the production of the coating should be able to be used, as well as a washability up to over 90 ° C. and also high color fastness with repeated washing. Ultimately, ironing after washing should be dispensed with.
- a transfer paper which has at least as a plastic coating: a polyurethane which can be crosslinked under the action of temperature through a methanol-etherified melamine-formaldehyde resin, in a mixture with an acrylic acid ester / acrylic acid copolymer, the latter being a thickener.
- the advantage of such a coating is that the coating (after the photocopy has been produced on it) can be removed from the paper as a film and placed positively on the textile base, in order to then iron it on and connect it to the textile fibers. It is also essential that a white pigment can be incorporated into the mixture (TiO2), so that the previously required white coating of dark (black) textiles is no longer necessary and the print can be transferred immediately with a single film.
- a mixture in the following weight ratios is particularly suitable for producing the coating: 2.5-10 parts of melamine formaldehyde resin as a 70% aqueous solution, 200-300 parts of polyurethane as a 40% aqueous dispersion and 7-36 parts of thickener in a 25% aqueous dispersion, the latter values depending on the desired application method on the paper straighten, and for the screen printing application process for finer stencils 7 and for coarser stencils 36 parts by weight are to be used. The request can of course also be made by doctoring.
- auxiliaries such as paraffin and / or defoamers and / or wetting agents and / or leveling agents to the mixture.
- the paraffin component serves to make it easier to remove the film from the paper and at the same time makes the surface tack-free.
- Particularly suitable as a polyurethane component are ionic or nonionic polyether or polyester polyurethanes.
- Sodium salt of sulfosuccinic acid is preferably used as the wetting agent and methoxymethylated melamine as the leveling agent together with nonionic surfactants in a suitable mixing ratio.
- the coating can preferably be produced from a mixture of 2.5-10 parts by weight of methanol-etherified melamine-formaldehyde resin (dissolved in water), 0-5 parts by weight of an aqueous, anionic paraffin emulsion, 0-100 parts by weight of titanium dioxide pigment, 0-1 parts by weight of defoamer (based on mineral oil ), 200-300 parts by weight of an aqueous dispersion of anionic polyester-polyurethane, 0-0.5 parts by weight of sodium sulfosuccinate, 0.5-2 parts by weight of leveling agent and 7-36 parts by weight of a 25% aqueous dispersion of acrylic acid ester-acrylic acid copolymer, the components in 10-20 parts by weight of water are mixed and stirred to a flowable mass.
- the titanium oxide pigment component may also be missing.
- aqueous acrylic acid-N-butyl ester-styrene copolymer dispersion can be added to the mixture.
- Textiles printed in accordance with the invention have the essential advantage that washing does not fade the image and thus completely eliminates the need for ironing to increase the color brilliance.
- the paper according to the invention can be used with particular advantage in the case of dark (black) fabrics.
- a white colored plastisol layer had to be applied to the fabric for such purposes, e.g. pressed onto paper by ironing. This had to have approximately the contour of the image, which was then cut to size and applied to the white coating.
- the edges become blurred, the image has to be cut mirror-inverted, the contour is based on simple outlines such as Rectangles limited. If instead a transparent printed film is ironed against an opaque second film in order to then apply the composite to the textile, the difficulty is that the image has to be viewed through the backing paper for cutting, which does not allow exact results.
- the procedure can now be much simpler.
- the image can be easily cut out on and with the paper.
- the polyurethane layer is then crosslinked under pressure and temperature, the temperature preferably being left to act on the back of the fabric, i.e. the fabric is ironed "left". Obviously, this eliminates a significant difficulty of all previously known printing processes, i.e. the print can be applied directly to the textile.
- the paper on which the print was initially placed can be easily selected on the side carrying the toner, ie placed on the outside, or a correspondingly larger paper can be selected for cutting.
- the paper can also be provided with a separating layer made of wax or silicone in a manner known per se.
- Transfer paper for transferring colored xerocopy prints to textile substrates consisting of a backing paper and a coating thereon, the coating containing methanol-etherified melamine-formaldehyde resin as a temperature-activable crosslinking component, at least one anionic polyester-polyurethane and acrylic acid ester-acrylic acid copolymer as a thickener.
- the substances are mixed in the 20 parts of water and homogenized, applied to a paper (e.g. doctor blade, screen printing) and allowed to set.
- a paper e.g. doctor blade, screen printing
- the result is a printable film which can be completely peeled off from paper and which can be ironed onto a textile at elevated temperatures.
- the products mentioned are commercial products and are used in their distributed form.

Abstract
Description
Die vorliegende Erfindung betrifft ein Transferpapier sowie ein Verfahren zur Übertragung von Fotokopien auf Textilien, wie insbesondere T-Shirts.The present invention relates to a transfer paper and a method for transferring photocopies to textiles, such as in particular T-shirts.
Derartige Transferpapiere tragen eine den Druck aufnehmende Kunststoffschicht, die heiß auf das Textil übertragen wird, wobei man den Druck auf das Textil aufbügelt und ggf. nach einer gewissen Abkühlungszeit das Papier abzieht, wonach Kunststoff und Druck auf dem Gewebe verbleiben. Da die Fotokopie ein Positivabzug ist, entsteht auf dem Textil ein Negativabdruck. Wünscht man ein Positiv-Bild auf dem Gewebe, so ist ein Negativabdruck vor dem Übertragen herzustellen, wie z.B. in der EP-05 22 898 A1 und DE-42 10 976 A1 beschrieben.Such transfer papers carry a pressure-absorbing plastic layer which is transferred hot to the textile, the pressure being ironed onto the textile and, if appropriate, the paper being removed after a certain cooling time, after which plastic and pressure remain on the fabric. Since the photocopy is a positive print, a negative impression is created on the textile. If you want a positive image on the tissue, a negative impression must be made before transfer, e.g. in EP-05 22 898 A1 and DE-42 10 976 A1.
Herkömmliche Drucke befriedigen nicht hinsichtlich der Brillianz der übertragenen Abbildung, insbesondere auf schwarzen Textilien, sowie der Waschbeständigkeit bei höheren Temperaturen. Weiße Textilien müssen nach dem Waschen nachgebügelt werden, um verblaßte Farben wieder zu verstärken.Conventional prints are unsatisfactory in terms of the brilliance of the transferred image, especially on black textiles, and the wash resistance at higher temperatures. White textiles must be ironed after washing in order to intensify faded colors.
Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, ein Transferpapier zu schaffen, mit dessen Hilfe direkt positive Abdrucke herstellbar sind und die ferner eine Kunststoffbeschichtung aufweisen, die eine höhere Brillianz des Abbildes gewährleistet und in die insbesondere zum Bedrucken schwarzer Textilien ein Weißpigment eingearbeitet werden kann. Zu dem soll als einziges bei der Herstellung der Beschichtung verwendetes Lösungsmittel-Wasser eingesetzt werden können, sowie eine Waschbarkeit bis zu über 90° C und ebenso hohe Farbbeständigkeit bei wiederholtem Waschen gegeben zu sein. Letztlich soll ein Nachbügeln nach dem Waschen entfallen.The object of the present invention is therefore to create a transfer paper which can be used to produce positive prints directly and which furthermore have a plastic coating which ensures a higher brilliance of the image and into which a white pigment can be incorporated, in particular for printing on black textiles . In addition, the only solvent water used in the production of the coating should be able to be used, as well as a washability up to over 90 ° C. and also high color fastness with repeated washing. Ultimately, ironing after washing should be dispensed with.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch ein Transferpapier, das als Kunststoffbeschichtung mindestens aufweist: ein unter Temperatureinwirkung durch ein methanolverethertes Melamin-Formaldehydharz vernetzbares Polyurethan, in Mischung mit einem Acrylsäureester-Acrylsäurecopolymer, wobei letzteres einen Verdicker darstellt.This object is achieved according to the invention by means of a transfer paper which has at least as a plastic coating: a polyurethane which can be crosslinked under the action of temperature through a methanol-etherified melamine-formaldehyde resin, in a mixture with an acrylic acid ester / acrylic acid copolymer, the latter being a thickener.
Der Vorteil einer solchen Beschichtung besteht darin, daß die Beschichtung (nach dem Herstellen der Fotokopie auf dieser) vom Papier als Folie abgezogen und positiv auf die textile Unterlage aufgelegt werden kann, um sie dann aufzubügeln und mit den Textilfasern zu verbinden. Von wesentlicher Bedeutung ist weiterhin, daß in die Mischung ein Weißpigment eingearbeitet werden kann (TiO₂), so daß die bisher erforderliche vorherige Weißbeschichtung von dunklen (schwarzen) Textilien nunmehr entfallen und der Druck sofort mit einer einzigen Folie übertragen werden kann.The advantage of such a coating is that the coating (after the photocopy has been produced on it) can be removed from the paper as a film and placed positively on the textile base, in order to then iron it on and connect it to the textile fibers. It is also essential that a white pigment can be incorporated into the mixture (TiO₂), so that the previously required white coating of dark (black) textiles is no longer necessary and the print can be transferred immediately with a single film.
Um die Griffigkeit bzw. Weichheit des Abbildes einstellen zu können, wird weiterhin vorgeschlagen, eine Mischung aus zwei Polyurethankomponenten einzusetzen, deren eine weicher ist.In order to be able to adjust the grip or softness of the image, it is further proposed to use a mixture of two polyurethane components, one of which is softer.
Besonders geeignet zur Herstellung der Beschichtung ist eine Mischung in folgenden Gewichtsverhältnissen:
2,5-10 Teile Melaminformaldehydharz als 70 %ige wässrige Lösung, 200-300 Teile Polyurethan als 40%ige wässrige Dispersion und 7-36 Teile Verdicker in 25 %iger wäßriger Dispersion, wobei die letzteren Werte sich nach dem gewünschten Auffragsverfahren auf das Papier richten, und für das Siebdruckauftragverfahren bei feineren Schablonen 7 und bei gröberen Schablonen 36 Gewichtsteile einzusetzen sind. Der Auffrag kann natürlich auch durch Rakeln erfolgen.A mixture in the following weight ratios is particularly suitable for producing the coating:
2.5-10 parts of melamine formaldehyde resin as a 70% aqueous solution, 200-300 parts of polyurethane as a 40% aqueous dispersion and 7-36 parts of thickener in a 25% aqueous dispersion, the latter values depending on the desired application method on the paper straighten, and for the screen printing application process for finer stencils 7 and for coarser stencils 36 parts by weight are to be used. The request can of course also be made by doctoring.
Zur Verbesserung der Qualität der Verarbeitbarkeit wird vorgeschlagen, der Mischung Hilfsmittel wie Paraffin und/oder Entschäumer und/oder Netzmittel und/oder Verlaufsmittel hinzuzufügen.To improve the quality of the processability, it is proposed to add auxiliaries such as paraffin and / or defoamers and / or wetting agents and / or leveling agents to the mixture.
Die Paraffinkomponente dient dabei dem leichteren Abziehen des hergestellten Films vom Papier und macht gleichzeitig die Oberfläche klebfrei.The paraffin component serves to make it easier to remove the film from the paper and at the same time makes the surface tack-free.
Als Polyurethankomponente eignen sich besonders ionische oder nichtionogene Polyether- oder Polyester-Polyurethane.Particularly suitable as a polyurethane component are ionic or nonionic polyether or polyester polyurethanes.
Bevorzugt wird als Netzmittel Natriumsalz der Sulfobernsteinsäure und als Verlaufsmittel methoxymethyliertes Melamin zusammen mit nichtionischen Tensiden in geeignetem Mischungsverhältnis eingesetzt.Sodium salt of sulfosuccinic acid is preferably used as the wetting agent and methoxymethylated melamine as the leveling agent together with nonionic surfactants in a suitable mixing ratio.
Die Beschichtung läßt sich vorzugsweise herstellen aus einer Mischung von 2,5-10 Gewichtsteilen methanolverethertem Melamin-Formaldehydharz (in Wasser gelöst), 0-5 Gewichtsteilen einer wäßrigen, anionischen Paraffinemulsion, 0-100 Gewichtsteilen Titandioxidpigment, 0-1 Gewichtsteilen Entschäumer (auf Mineralölbasis), 200-300 Gewichtsteilen einer wäßrigen Dispersion von anionischem Polyester-Polyurethan, 0-0,5 Gewichtsteilen Natriumsulfosuccinat, 0,5-2 Gewichtsteilen Verlaufsmittel und 7-36 Gewichtsteilen einer 25 %igen wäßrigen Dispersion von Acrylsäureester-Acrylsäurecopolymerisat, wobei die Komponenten in 10-20 Gewichtsteilen Wasser gemischt und zu einer fließfähigen Masse gerührt werden.The coating can preferably be produced from a mixture of 2.5-10 parts by weight of methanol-etherified melamine-formaldehyde resin (dissolved in water), 0-5 parts by weight of an aqueous, anionic paraffin emulsion, 0-100 parts by weight of titanium dioxide pigment, 0-1 parts by weight of defoamer (based on mineral oil ), 200-300 parts by weight of an aqueous dispersion of anionic polyester-polyurethane, 0-0.5 parts by weight of sodium sulfosuccinate, 0.5-2 parts by weight of leveling agent and 7-36 parts by weight of a 25% aqueous dispersion of acrylic acid ester-acrylic acid copolymer, the components in 10-20 parts by weight of water are mixed and stirred to a flowable mass.
Sollen weiße Textilien bedruckt werden, so kann die Titanoxidpigmentkomponente auch fehlen.If white textiles are to be printed, the titanium oxide pigment component may also be missing.
Es können bis zu 50 Gewichtsteile einer wäßrigen Acrylsäure-N-Butylester-Styrol-Copolymerdispersion der Mischung beigefügt sein.Up to 50 parts by weight of an aqueous acrylic acid-N-butyl ester-styrene copolymer dispersion can be added to the mixture.
Weiterhin wird vorgeschlagen, zwischen dem Papier (Gewicht ca. 100 g/m²) und der Polyurethanschicht eine Beschichtung aus einem Ethylenvinylacetat-Terpolymer vorzugsweise mit 9-28 % Vinylacetat und 0,5-3 % Maleinsäuregruppen vorzusehen. Diese Schicht bewirkt wesentliche Vorteile - zum einen entsteht eine hochtemperaturfeste, bis etwa 95° C waschbare Beschichtung, zum zweiten wird ein matter weicher Griff erzielt bei unverminderter Farbkraft und sehr hoher Waschbeständigkeit.It is further proposed to provide a coating of an ethylene vinyl acetate terpolymer, preferably with 9-28% vinyl acetate and 0.5-3% maleic acid groups, between the paper (weight approx. 100 g / m²) and the polyurethane layer. This layer has significant advantages - on the one hand a high temperature resistant, washable up to 95 ° C coating, on the other hand a matt soft handle is achieved with undiminished color strength and very high wash resistance.
Erfindungsgemäß bedruckte Textilien weisen den wesentlichen Vorteil auf, daß durch das Waschen das Abbild nicht verblaßt und ein Nachbügeln zur Erhöhung der Farbrillianz somit vollständig entfällt.Textiles printed in accordance with the invention have the essential advantage that washing does not fade the image and thus completely eliminates the need for ironing to increase the color brilliance.
Mit besonderem Vorteil läßt sich das erfindungsgemäße Papier bei dunklen (schwarzen) Geweben verwenden.The paper according to the invention can be used with particular advantage in the case of dark (black) fabrics.
Bisher mußte für solche Zwecke auf das Gewebe zunächst eine weiß eingefärbte Plastisolschicht aufgetragen, z.B. von einem Papier durch Bügeln aufgepreßt werden. Dieses mußte etwa die Kontur der Abbildung aufweisen, die dann, entsprechend zugeschnitten, auf die weiße Beschichtung aufgetragen wird. Dabei treten vielfältige Probleme auf, die Ränder werden unscharf, das Bild muß spiegelverkehrt geschnitten werden, die Kontur ist auf einfache Umrisse wie z.B. Rechtecke beschränkt. Wird statt dessen eine transparente bedruckte Folie gegen eine opake zweite Folie gebügelt um den Verbund danach auf das Textil aufzubringen, so besteht die Schwierigkeit darin, daß die Abbildung zum Ausschneiden durch das Trägerpapier hindurch betrachtet werden muß, was keine exakten Ergebnisse zuläßt.Previously, a white colored plastisol layer had to be applied to the fabric for such purposes, e.g. pressed onto paper by ironing. This had to have approximately the contour of the image, which was then cut to size and applied to the white coating. Various problems arise, the edges become blurred, the image has to be cut mirror-inverted, the contour is based on simple outlines such as Rectangles limited. If instead a transparent printed film is ironed against an opaque second film in order to then apply the composite to the textile, the difficulty is that the image has to be viewed through the backing paper for cutting, which does not allow exact results.
Erfindungsgemäß kann nunmehr viel einfacher vorgegangen werden. Nach dem Bedrucken des beschichteten Papiers z.B. mit Hilfe eines Fotokopiergerätes kann das Bild auf dem Papier und mit diesem mühelos ausgeschnitten werden. Danach löst man die als Folie auf dem Papier adhäsiv gebundene Beschichtung ab und legt sie mit der Sichtseite, d.h. in positiver Abbildung auf die Textilunterlage. Anschließend wird unter Druck und Temperatur die Polyurethanschicht vernetzt, wobei vorzugsweise die Temperatur von der Rückseite des Gewebes einwirken gelassen wird, d.h. das Gewebe wird "links" gebügelt. Erkennbar entfällt damit eine wesentliche Schwierigkeit aller bisher bekannten Druckverfahren, d.h. der Druck kann direkt auf das Textil aufgetragen werden.According to the invention, the procedure can now be much simpler. After printing on the coated paper e.g. With the help of a photocopier, the image can be easily cut out on and with the paper. Then remove the coating that is adhesively bound as a film on the paper and place it with the visible side, i.e. in a positive illustration on the textile base. The polyurethane layer is then crosslinked under pressure and temperature, the temperature preferably being left to act on the back of the fabric, i.e. the fabric is ironed "left". Obviously, this eliminates a significant difficulty of all previously known printing processes, i.e. the print can be applied directly to the textile.
Um die Folie beim Bügeln zu schützen, kann in einfacher Weise das Papier, auf dem sich der Druck zunächst befand, auf die den Toner tragende Seite, d.h. außen aufgelegt, oder aber bei Zuschnitten ein entsprechendes größeres Papier gewählt werden.In order to protect the film during ironing, the paper on which the print was initially placed can be easily selected on the side carrying the toner, ie placed on the outside, or a correspondingly larger paper can be selected for cutting.
Zum leichteren Abziehen der Folienbeschichtung kann das Papier mit einer Trennschicht auch in ansich bekannter Weise aus Wachs oder Silikon versehen sein.To make it easier to remove the film coating, the paper can also be provided with a separating layer made of wax or silicone in a manner known per se.
Anhand der folgenden Beispiele wird die vorliegende Erfindung näher erläutert.The present invention is illustrated by the following examples.
Transferpapier zum Übertragen von farbigen Xerokopiedrucken auf textile Unterlagen, bestehend aus einem Trägerpapier sowie einer darauf befindlichen Beschichtung, wobei die Beschichtung methanolverethertes Melamin-Formaldehydharz als durch Temperatur aktivierbare Vernetzungskomponente, mindestens ein anionisches Polyester-Polyurethan sowie Acrylsäureester-Acrylsäure-Copolymer als Verdicker enthält.Transfer paper for transferring colored xerocopy prints to textile substrates, consisting of a backing paper and a coating thereon, the coating containing methanol-etherified melamine-formaldehyde resin as a temperature-activable crosslinking component, at least one anionic polyester-polyurethane and acrylic acid ester-acrylic acid copolymer as a thickener.

Die Substanzen werden in den 20 Teilen Wasser gemischt und homogenisiert, auf ein Papier aufgetragen (z. B: Rakeln, Siebdruck) und abbinden lassen. Es entsteht ein vom Papier vollständig abziehbarer bedruckbarer Film, der sich bei erhöhten Temperaturen auf ein Textil aufbügeln läßt.The substances are mixed in the 20 parts of water and homogenized, applied to a paper (e.g. doctor blade, screen printing) and allowed to set. The result is a printable film which can be completely peeled off from paper and which can be ironed onto a textile at elevated temperatures.
