Abstract

A differential printing process for textiles, in particular carpets, made of polyamide fibres of various dyeability, is characterized in that a cationic resist based on quaternary fatty amine polyglycol ethers or on quaternary ammonium polyglycols is added to the usual printing paste for polyamide fibres. The printing paste may also contain several different dyestuff types, as in the differential dyeing process, and may if required be continuously cross-dyed in a manner known per se in a single operation by a wet-on-wet differential dyeing process. To carry out this process, a usual printing paste for polyamide fibres is used which is characterized in that it contains a cationic resist based on quaternary fatty amine polyglycol ethers or quaternary ammonium polyglycols.

Description

Die Erfindung betrifft den in den Patentansprüchen 1 und 6 angegeben Gegenstand.The invention relates to the subject matter specified in claims 1 and 6.

Durch chemische Modifizierung von Polyamidfaserstoffen ist es möglich, ein unterschiedliches färberisches Verhalten zu erreichen. Auf diese Weise kann man bei einer Stückfärbung einbadig Hell-Dunkeleffekte bzw. Mehrfarbeneffekte erzielen.By chemical modification of polyamide fiber materials it is possible to have a different coloring behavior to reach. In this way you can dye a piece achieve single-bath light-dark effects or multi-color effects.

Polyamide, die Wasser absorbieren und quellen, wie Nylon 6 und 66, können verhältnismäßig einfach mit Dispersionsfarbstoffen, Säurefarbstoffen oder Metallkomplexfarbstoffen gefärbt werden. Das Färben von Polyamidfasern mit Säurefarbstoffen resultiert aus der Umsetzung mit den Aminoendgruppen. Die Anzahl dieser reaktiven Stellen wird vom Molekulargewicht beeinflußt, kann jedoch durch Zusätze, wie Viskositätsstabilisatoren modifiziert werden. Z.B. blockieren carboxygruppenhaltige Stabilisatoren Aminoendgruppen und vermindern die Affinität für Säurefarbstoffe. Die Verwendung von primären aliphatischen Aminen oder Diaminen liefert zusätzliche basische Stellen und erhöht die Säureanfärbbarkeit. Die Einführung von tertiären Aminogruppen in die Kette erhöht die Absorption von Säurefarbstoffen stark.Polyamides that absorb and swell water, such as nylon 6 and 66, can be relatively easy with Disperse dyes, acid dyes or Metal complex dyes are dyed. Coloring Polyamide fibers with acid dyes result from the Implementation with the amino end groups. The number of these reactive sites is influenced by the molecular weight, can however, through additives such as viscosity stabilizers be modified. E.g. block carboxy-containing Stabilizers amino end groups and reduce affinity for acid dyes. The use of primary aliphatic amines or diamines provide additional alkaline spots and increases acid dyeability. The Introduction of tertiary amino groups into the chain increased the absorption of acid dyes strongly.

Polyamide können modifiziert werden, um basische Farbstoffe aufzunehmen indem man stark saure Gruppen einführt, wie Sulfonsäuregruppen, z.B. 5-Sulfoisophthalsäure im äquimolaren Gemisch mit 1,6-Diaminohexan.Polyamides can be modified to basic dyes by introducing strongly acidic groups like Sulfonic acid groups, e.g. 5-sulfoisophthalic acid in equimolar mixture with 1,6-diaminohexane.

Somit können Vielfarbeneffekte, die abgestufte Farbtiefe oder veränderliche Farbe und Farbschattierungen sein können, durch Färben von Geweben aus gemischten Polyamidfasern mit unterschiedlicher Anfärbbarkeit in einem einzigen Bad erzeugt werden, das Säure-, basische und Dispersionsfarbstoffe enthält.Thus, multi-color effects, the graded color depth or changing color and shades of color, by dyeing fabrics made of mixed polyamide fibers with different dyeability in a single bath are generated, the acidic, basic and Contains disperse dyes.

Diese Arbeitsweise wird auch für die Stückfärbung von Teppichen aus Polyamidfasern angewandt, wobei entweder einfarbige Veloure oder Schlingenqualitäten aus texturierten Endlosgarnen von unterschiedlicher Anfärbbarkeit, also Differentialdyegarne, hergestellt werden. Wenn also ein Teppich, der aus drei verschiedenen Garntypen besteht, in der Kufe oder auf der Continueanlage gefärbt wird, bekommt man mehrfarbige Färbungen, ein sogenanntes Differentialdyeing.This way of working is also used for piece dyeing Carpets made of polyamide fibers are applied, being either plain-colored velor or loop qualities made of textured Continuous yarns of different dyeability, so Differential dyed yarns. So if one Carpet consisting of three different types of yarn in the skid or on the continuation system gets colored multicolored dyeings, a so-called Differential dyeing.

Diese seit langer Zeit unter dem Begriff "Differential-Dyeing-Verfahren" bekannte Arbeitsweise liefert jedoch beim Drucken nicht diesen Effekt. Wenn man nämlich auf solche Ware druckt, bleibt der Druck einfarbig oder höchstens von unten her kann man ahnen, daß die Grundqualität aus mehreren Garntypen besteht.This for a long time under the term "Differential dyeing process" known way of working does not provide this effect when printing. If namely prints on such goods, the print remains monochrome or at most from below you can guess that the Basic quality consists of several types of yarn.

Es besteht demnach ein starker Bedarf, dieses "Differential-Dyeing" auch als Druckverfahren anwenden zu können, da man bis jetzt beim Drucken mit einer Schablone nur eine Farbe erzeugen kann und somit für jede weitere Farbe auch eine weitere Schablone benötigt.So there is a strong need for this Differential dyeing can also be used as a printing process can, since until now when printing with a stencil can only produce one color and therefore for each further Color also needs another stencil.

Aus der DE 36 23 967 A1 ist ein Verfahren zur Herstellung von Reserve- oder Bunteffekten auf textilen Flächengebilden und Garnen aus natürlichen oder synthetischen Polyamiden bekannt, wobei man das Textilmaterial mit einer anionische Farbstoffel enthaltenden Färbeflotte imprägniert, direkt anschließend lokal auf das Textilmaterial eine oder mehrere Flotten oder Pasten aufbringt, die ein 5 bis 10-fach alkoxyliertes Fettdiamin, gegebenenfalls zusammen mit einem oder mehreren anionischen Farbstoffen oder Aufhellern oder Dispersionsfarbstoffen, enthält und danach das Textilmaterial einer Hitzebehandlung zur Fixierung der Farbstoffe bzw. Aufheller unterwirft, wobei die Stufen A) und B), also Färbung und Druck, auch in umgekehrter Reihenfolge durchgeführt werden können.
Die DE 32 22 516 C2 zeigt ein Verfahren zur Herstellung von Reserven auf mit anionischen Farbstoffen anfärbbaren textilen Materialien, wobei man lokal auf das Textilmaterial bei Raumtemperatur mindestens eine Flotte oder Paste aufbringt, die mindestens ein eine Affinität gegenüber anionischen Farbstoffen mit einem K'pH6-Wert≥5 aufweisendes alkoxyliertes Fettamin oder -polyamin einer spezifischen Formel als solches, in Form der freien Base oder in protonierter oder quaternierter Form enthält, direkt danach ohne Zwischenspülen, -waschen und/oder -trocknen das Textilmaterial mit einer sauren Färbeflotte, die mindestens einen anionischen Farbstoff mit einem K'pH6-Wert≥5 enthält, imprägniert, und danach das Textilmaterial einer Hitzebehandlung zur Fixierung der Farbstoffe unterwirft.DE 36 23 967 A1 discloses a process for the production of reserve or colored effects on textile fabrics and yarns made of natural or synthetic polyamides, the textile material being impregnated with a dye liquor containing anionic dyes, directly subsequently one or more locally on the textile material Applies liquors or pastes containing a 5 to 10-fold alkoxylated fatty diamine, optionally together with one or more anionic dyes or brighteners or disperse dyes, and then subjecting the textile material to a heat treatment to fix the dyes or brighteners, stages A) and B), i.e. coloring and printing, can also be carried out in reverse order.
DE 32 22 516 C2 shows a process for the production of reserves on textile materials that can be dyed with anionic dyes, at least one liquor or paste being applied locally to the textile material at room temperature, which has at least one affinity for anionic dyes with a K ' pH6 - Containing ≥5 alkoxylated fatty amine or polyamine of a specific formula as such, in the form of the free base or in protonated or quaternized form, immediately afterwards without intermediate rinsing, washing and / or drying the textile material with an acid dyeing liquor containing at least one contains anionic dye with a K ' pH6 value ≥5, impregnated, and then the textile material is subjected to a heat treatment to fix the dyes.

Diese Verfahren und anionischen Mittel ergeben jedoch bei der Anwendung auf den Differentialdruck von Textilwaren aus Polyamidfasern unterschiedlicher Anfärbbarkeit keinen kräftigen und sauberen Druck, sondern beim Aufbringen dieser Pasten auf ein Differential und anschließendem Färben ist als Ergebnis immer noch eine fast Uni- oder Weißreserve und der kationisch anfärbbare Polyamidanteil macht sich bestenfalls als leicht heller Anteil bemerkbar.However, these methods and anionic agents result in the application to the differential pressure of textile goods Polyamide fibers of different dyeability none strong and clean pressure, but when applying this Paste on a differential and then dye it as a result still an almost plain or white reserve and the cationic dyeable polyamide portion makes itself felt noticeable at best as a slightly light portion.

Schließlich ist in der DE 42 19 317 A1 ein kationisches Tensid, welches an sich beim Färben von mit anionischen Farbstoffen färbbaren Substraten als Reserviermittel wirkt, oder ein Gemisch solcher Tenside, und ein kationisches Tensid, welches an sich beim Färben von Polyacrylnitril mit kationischen Farbstoffen als Retardiermittel wirkt, oder ein Gemisch solcher Tenside enthalten als Reserviermittel für mit anionischen Farbstoffen färbbare Substrate zeigt. Dieses kationische Tensid ist jedoch nur als Reserviermittel für mit anionischen Farbstoffen färbbaren Substanzen gezeigt und verwendbar.Finally, DE 42 19 317 A1 is cationic Surfactant, which in itself when dyeing with anionic Dyes dyeable substrates acts as a reservation agent, or a mixture of such surfactants, and a cationic Surfactant, which is used in the dyeing of polyacrylonitrile cationic dyes act as a retardant, or a Mixture of such surfactants contain as a reservation agent for shows substrates dyeable with anionic dyes. This However, cationic surfactant is only used as a reservation agent for shown with anionic dyes and usable.

EP-A-0 487 771 beschreibt die Herstellung von Weiß- und Buntreserven unter oder auf Färbungen mit anionischen Farbstoffen auf Polyamidfasermaterial. Als Reservierungsmittel werden quaternierte alkoxylierte Dialkylmonoamin-Verbindungen verwendet. Diese Verbindungen werden in einem zweistufigen Verfahren hergestellt.EP-A-0 487 771 describes the production of white and colored reserves under or for dyeings with anionic dyes on polyamide fiber material. As Reservation agents are quaternized alkoxylated dialkyl monoamine compounds used. These connections are in a two-step process Process manufactured.

Die Anwendung dieser anionischen Mittel auf Polyamidfasern unterschiedlicher Anfärbbarkeit ergibt jedoch keinen kräftigen sauberen Druck, sondern beim Aufbringen dieser Pasten auf ein Differential und anschliessendem Färben ist als Ergebnis immer noch eine fast Uni- oder Weiß-Reserve vorhanden und der kationisch anfärbbare Polyamidteil macht sich bestenfalls als leicht heller Anteil bemerkbar.The application of these anionic agents to polyamide fibers different Dyeability, however, does not result in a strong clean print, but in the Applying these pastes to a differential and then dyeing is as The result is still an almost uni or white reserve and that At best, cationically dyeable polyamide part makes up as a slightly light part noticeable.

WO-A-80/01577 beschreibt ein Zweistufenverfahren für Ton-in-Ton-Reserven oder Multicoloreffekte nach dem Naß-auf-Naß-Verfahren, in welchem als Reservierungsmittel alkoxylierte Fettamine verwendet werden. Das zu färbende Textilmaterial wird zuerst mit einer üblichen Färbeflotte mit anionischen Farbstoffen mit einem K'-Wert von ≥ 5 vorbehandelt und direkt anschließend mit den vorgenannten Reservierungsmitteln und gegebenenfalls anionischen Farbstoffen behandelt. Für die erste und zweite Phase dieses Verfahrens müssen anionische Farbstoffe mit unterschiedlichen K'-Werten (möglichst zwei K'-Werte Unterschied) benutzt werden.WO-A-80/01577 describes a two-step process for tone-on-tone reserves or Multicolor effects after the wet-on-wet process, in which as Reservation agents alkoxylated fatty amines can be used. The one to be colored Textile material is first made with a common dye bath with anionic Dyes with a K 'value of ≥ 5 pretreated and immediately afterwards with the aforementioned reservation agents and possibly anionic Dyes treated. For the first and second phases of this procedure anionic dyes with different K 'values (preferably two K' values Difference) can be used.

    Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, ein verbessertes Verfahren für den Differentialdruck von Textilfasern, insbesondere von Teppichen, aus Polyamidfasern unterschiedlicher Anfärbbarkeit sowie ein Mittel zur Durchführung eines solchen verbesserten Verfahrens bereitzustellen.The object of the present invention is therefore an improved Process for differential printing of textile fibers, especially carpets, made of polyamide fibers of different dyeability and a means for To provide implementation of such an improved method.

    Gelöst wird diese Aufgabe durch ein Verfahren gemäß Anspruch 1 sowie durch die Verwendung gemäß Anspruch 6. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This object is achieved by a method according to claim 1 and by Use according to claim 6. Advantageous configurations result from the subclaims.

    Es wurde nun gefunden, daß man, wie beim Stückfärben Teppiche oder Textilien allgemein, die aus verschiedenen Garntypen bestehen die unterschiedliches färberisches Verhalten haben, mehrfarbig drucken kann, wenn man der Druckpaste ein kationisches Reservierungsmittel auf der Basis von quartären Fettaminpolyglykoletherderivaten und/oder quaternären Ammoniumpolyglykolen und kationische und anionische Farbstoffe zusammen zusetzt.It has now been found that, as with piece dyeing Carpets or textiles in general, which are made of different Yarn types are made up of different dye Have behavior, can print in multiple colors if you can Printing paste a cationic reservation agent on the Basis of quaternary fatty amine polyglycol ether derivatives and / or quaternary ammonium polyglycols and cationic and anionic dyes together.

    Das bedeutet, daß man aus einer Schablone und aus einer Druckpaste je nach der Beschaffenheit der Grundware bunte Drucke machen kann. Wenn der Teppich z.B. aus drei verschiedenen Garntypen besteht, die jeweils unterschiedliches färberisches Verhalten zeigen, kann man mit einer Schablone drei Farben und demgemäß mit zwei Schablonen sechs Farben und mit drei Schablonen neun Farben erzielen, da sich die Colorierungsmöglichkeiten je nach Anzahl der unterschiedlich anfärbenden Polyamidtypen im Teppich oder in der Textilie entsprechend vervielfachen.This means that you can use one template and one Printing paste colored depending on the nature of the basic product Can make prints. If the carpet e.g. out of three different yarn types exist, each you can show different coloring behavior with one stencil three colors and accordingly with two Stencils six colors and with three stencils nine colors achieve, since the color options vary depending on Number of differently colored polyamide types in the Multiply carpet or textile accordingly.

    Die Ware kann entweder in Naß-auf-Naß-Verfahren bedruckt und gefärbt werden oder bedruckte Ware kann nachträglich in der Kufe gefärbt werden.The goods can either be printed in wet-on-wet processes and can be dyed or printed goods subsequently in the Skids are colored.

    Die Rohware muß lediglich aus verschieden anfärbbaren Polyamidsorten bestehen.The raw goods only have to be made of different colors Types of polyamides exist.

    Die Arbeitsweise besteht allgemein darin, daß die Ware entweder trocken bedruckt oder vorher benetzt wird, z.B. auf einem vor der Druckmaschine installierten Foulard. Anschließend wird kontinuierlich mit einer oder mehreren Schablonen bedruckt. Dann wird mit Färbeflotte kontinuierlich, naß-in-naß übergossen und bei Sattdampf ineinem Arbeitsgang ca. 10 Minuten gedämpft (t = 98°C). Anschließend wird kontinuierlich gewaschen und abgesaugt.The way of working is generally that the goods either printed dry or wetted beforehand, e.g. on a foulard installed in front of the press. Subsequently, one or more is continuously Stencils printed. Then with dye liquor poured continuously, wet-on-wet and with saturated steam steamed for approx. 10 minutes in one operation (t = 98 ° C). It is then washed and suctioned off continuously.

    Als weitere Möglichkeit kann die Ware nur bedruckt, gedämpft und getrocknet und dann in der Haspelkufe zwischen 60° bis 96°C diskontinuierlich gefärbt werden.As a further possibility, the goods can only be printed, steamed and dried and then in the reel skid between 60 ° to 96 ° C can be colored discontinuously.

    Das erfindungsgemäße Verfahren und das erfindungsgemäß verwendete Mittel kann auch auf einer Spritzdruckanlage benutzt werden. Diese Spritzdruckanlagen, insbesondere die Chromo-Jet-Anlagen und das Arbeiten mit ihnen ist dem Fachmann wohlbekannt und braucht hier nicht näher erläutert werden.The method according to the invention and the agent used according to the invention can also be based on a spray pressure system can be used. This Spray pressure systems, especially the Chromo-Jet systems and working with them is well known to those skilled in the art and need not be explained here.

    Das wesentliche bei diesem Verfahren ist ein kationisches Reservierungsmittel auf des Basis von quaternären Ammoniumpolyglykolen und/oder quartären Fettaminpolyglykolethern, wobei letztere bevorzugt werden.The essence of this process is cationic Reservation funds based on quaternary Ammonium polyglycols and / or quaternary Fettaminpolyglykolethern, the latter preferred will.

  • 2. Raniresist® KT 200 von Ranie Chemie (Kombination quaternärer Ammoniumpolyglykole in wäßriger Aufbereitung) also quartäre Fettaminpolyglykolether oder quartäre Ammoniumpolyglykole ermöglichen durch ihren Zusatz zur Druckpaste bei den üblichen leicht saueren pH-Werten von etwa 3 bis 5, insbesondere etwa 4, einen Differentialdruck wie dies sonst nur bei der Färbung möglich ist.

    Selbstverständlich kann man bei geeigneter Wahl der Polyamidsorten auch andere Säure- sowie Metallkomplexfarbstoffe für sauer anfärbbare Fasertypen nehmen, z.B. statt Irgalanschwarz ein Nylosanschwarz.Of course, with a suitable choice of Polyamide grades also other acid as well Metal complex dyes for acid-dyeable fiber types take, e.g. instead of irgalan black a nylosan black.

    Zusammenfassend ist also zu sagen, daß die Arbeitsweise grundsätzlich die gleiche ist wie beim üblichen Drucken und nachträglichen Färben, wobei jedoch durch die Verwendung des quarternären Fettaminpolyglykolethers schon beim Drucken die unterschiedlichen Farben aus der Druckpaste entstehen.In summary, it can be said that the way of working is basically the same as for normal printing and subsequent dyeing, but by using the quaternary fatty amine polyglycol ether already when printing the different colors arise from the printing paste.
