Definitions
- the invention relates to a method for producing aminated cotton fibers.
- European laid-open specification EP 0 546 476 A1 describes a "process for producing a modified fiber material and a process for dyeing the modified fiber material with anionic dyes".
- the fiber material is modified in such a way that an aliphatic or cyclic compound containing amino and ester groups is applied to the material and subjected to a thermal treatment. Another possibility is to leave the material in such a solution for a long time at an elevated temperature.
- the materials to be modified are ready-to-dye, ie boiled and bleached cotton and cotton blended fabrics. This procedure, namely to subsequently modify ready-to-use materials in order to then dye them free of salt and alkali, is very uneconomical and unecological in a total cost calculation.
- This object is achieved by a process for the production of aminated cotton fibers, characterized in that raw cotton or raw cotton-polyester mixtures are simultaneously boiled, boiled or dry mercerized by the addition of one, if necessary, by 1 or 2 or more hydroxyl-substituted, saturated aliphatic compound of 3 to 15 carbon atoms with at least one primary, secondary, tertiary or quaternary amino group and at least one hydrolyzable ester group in which the saturated radical (s) branches in a straight chain and / or is (are) and can optionally be interrupted by one or more hetero groups, modified.
- esters groups of the compounds containing amino groups are a sulfato or phosphato group or a C1-C4-alkanoyloxy group, phenylsulfonyloxy or one on the benzene nucleus by substituents from the group carboxy, C1-C4-alkyl, have proven to be favorable C1-C4 alkoxy and nitro substituted phensulfonyloxy group.
- N can also be used advantageously - ( ⁇ -Sulfatoethyl) piperidine, 2-sulfato-3-hydroxy-1-aminopropane, 3-sulfato-2-hydroxy-1-aminopropane, 1-sulfato-3-hydroxy-2-aminopropane , 3-Hydroxy-1-sulfato-2-aminopropane, 2,3-disulfato-1-aminopropane or 1,3-disulfato-2-aminopropane, a derivative of these compounds with another ester group mentioned above instead of that Sulfato group, especially N- (2-sulfatoethyl) piperazine sulfate.
- those amino compounds that have an ⁇ -chloro- ⁇ -hydroxy substitution as a reactive residue on the amine component are also suitable for the modification of raw cotton articles.
- compounds which can react with hydroxyl groups, for example cellulose, or amino and thiol groups, for example wool and silk, and which are capable of forming a covalent chemical bond are also suitable for the modification of raw cotton articles.
- the modification during the brewing or boiling of raw cotton articles can be carried out continuously or discontinuously.
- Soda lye with about 5 to 30 g / l NaOH is used as the baking or decoction liquid in a batch process. It is preferably carried out in closed tanks at temperatures between 80 ° C and 120 ° C, preferably 90 and 102 ° C.
- the pretreatment agent can be added linearly, degressively or directly.
- the concentrations are between 10 and 100 g / l, preferably 15 to 30 g / l.
- the modification according to the invention in discontinuous form can directly follow a bleaching process with hydrogen peroxide by adding the amount of alkali required for the pretreatment to the bleaching solution, thereby destroying excess bleaching agent and then adding the modification agent. It has proven to be advantageous if no peroxide stabilizer is added to the bleaching solution.
- the amounts of NaOH fluctuate between 5 to 20% by weight, based on the weight of the goods, depending on the type of energy supply and the type of fleet order.
- Based on the weight of the goods between 2 and 10% by weight, preferably 3 and 8% by weight, of modification agent are used.
- the modification according to the invention can directly follow a continuous bleaching process by squeezing an alkaline active substance solution which has been strengthened two to three times compared to a conventional liquor onto the pre-bleached, still very moist material and then subjecting the goods to a steaming process.
- No stabilizer should be added to the solution for the pre-bleaching in order to ensure that after squeezing the strongly alkaline modification liquor, the hydrogen peroxide is quickly destroyed and thus no fiber damage occurs.
- the textile fiber material that is used in the pretreatment process according to the invention can be present in all processing states, such as yarn, flake, sliver and piece goods (fabric).
- An essential and surprising advantage of the method according to the invention is that the fiber damage that always occurs in the course of boiling or baking processes is significantly reduced during pretreatment with said modification agents.
- Mercerization processes are also suitable for modification.
- the preferred embodiment is dry mercerization by squeezing a sodium hydroxide solution of 22 to 32 ° Be, preferably 24 ° Be, which contains between 30 and 120 g of modification agent per liter, onto the fabric.
- the goods are then over dried on a stenter with hot air at 120 ° C.
- a wash-out process a material is obtained which has an increased gloss and can be dyed free of salt and alkali according to the invention.
- Another embodiment is the impregnation with hot, modification agent-containing liquor. Following the hot impregnation the goods pass through a roller marking compartment.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung aminierter Baumwollfasern.The invention relates to a method for producing aminated cotton fibers.
In der Europäischen Offenlegungsschrift EP 0 546 476 A1 wird ein "Verfahren zur Herstellung eines modifizierten Fasermaterials und ein Verfahren zum Färben des modifizierten Fasermaterials mit anionischen Farbstoffen" beschrieben. Die Modifizierung des Fasermaterials erfolgt in der Weise, daß man eine amino-und estergruppenhaltige aliphatische oder cyclische Verbindung auf das Material aufbringt und einer thermischen Behandlung aussetzt. Eine weitere Möglichkeit ist, das Material in einer solchen Lösung über längere Zeit bei erhöhter Temperatur zu belassen.
Bei dem zu modifizierenden Materialien handelt es sich jeweils um färbefertige, d.h. abgekochte und gebleichte Baumwoll- und Baumwoll-Mischgewebequalitäten.
Diese Verfahrensweise, nämlich färbefertige Materialien nachträglich zu modifizieren, um sie dann salz- und alkalifrei zu färben, stellt sich bei einer Gesamtkostenkalkulation als sehr unökonomisch und unökologisch dar.European laid-open specification EP 0 546 476 A1 describes a "process for producing a modified fiber material and a process for dyeing the modified fiber material with anionic dyes". The fiber material is modified in such a way that an aliphatic or cyclic compound containing amino and ester groups is applied to the material and subjected to a thermal treatment. Another possibility is to leave the material in such a solution for a long time at an elevated temperature.
The materials to be modified are ready-to-dye, ie boiled and bleached cotton and cotton blended fabrics.
This procedure, namely to subsequently modify ready-to-use materials in order to then dye them free of salt and alkali, is very uneconomical and unecological in a total cost calculation.
Es bestand daher ein großer Bedarf nach einem Verfahren, das den Prozeß der Modifikation von Baumwolle in Verfahrensschritte integriert, die ohnehin mit Baumwolle durchgeführt werden müssen, um sie mit Reaktivfarbstoffen einfärben zu können, das also auch mit roher unvorbehandelter Baumwolle durchgeführt werden kann.There was therefore a great need for a process which integrates the process of modifying cotton into process steps which have to be carried out with cotton anyway in order to be able to dye them with reactive dyes, and which can therefore also be carried out with raw, untreated cotton.
Diese Aufgabe wird gelöst durch ein Verfahren zur Herstellung aminierter Baumwollfasern, dadurch gekennzeichnet, daß man Rohbaumwolle oder Rohbaumwolle-Polyester-Gemische gleichzeitig mit dem Abkochen, Beuchen oder Trockenmercerisieren durch Zusatz von einer gegebenenfalls durch 1 oder 2 oder mehrere Hydroxygruppen substituierten, gesättigten aliphatischen Verbindung von 3 bis 15 C-Atomen mit mindestens einer primären, sekundären, tertiären oder quartären Aminogruppe und mindestens einer hydrolysierbaren Estergruppe, in welcher der (die) gesättigte(n) Rest(e) geradkettig, verzweigt und/oder cyclisch ist (sind) und gegebenenfalls durch ein oder mehrere Heterogruppen unterbrochen sein kann (können), modifiziert.This object is achieved by a process for the production of aminated cotton fibers, characterized in that raw cotton or raw cotton-polyester mixtures are simultaneously boiled, boiled or dry mercerized by the addition of one, if necessary, by 1 or 2 or more hydroxyl-substituted, saturated aliphatic compound of 3 to 15 carbon atoms with at least one primary, secondary, tertiary or quaternary amino group and at least one hydrolyzable ester group in which the saturated radical (s) branches in a straight chain and / or is (are) and can optionally be interrupted by one or more hetero groups, modified.

Vorteilhaft verwenden lassen sich auch z.B. die Verbindungen N-(β-Sulfatoethyl)-piperazin, N-[β-(β-Sulfatoethoxy)-ethyl]piperazin, N-(γ-Sulfato-β-hydroxy-propyl)-pyrrolidin, N-(β-Sulfatoethyl)-piperidin, 2-Sulfato-3-hydroxy-1-amino-propan, 3-Sulfato-2-hydroxy-1-amino-propan, 1-Sulfato-3-hydroxy-2-amino-propan, 3-Hydroxy-1-sulfato-2-amino-propan, 2,3-Disulfato-1-amino-propan oder 1,3-Disulfato-2-amino-propan, ein Derivat dieser Verbindungen mit einer anderen vorstehend genannten Estergruppe statt der Sulfatogruppe, insbesondere N-(2-Sulfatoethyl)-piperazinsulfat.The compounds N- (β-sulfatoethyl) piperazine, N- [β- (β-sulfatoethoxy) ethyl] piperazine, N- (γ-sulfato-β-hydroxypropyl) pyrrolidine, N can also be used advantageously - (β-Sulfatoethyl) piperidine, 2-sulfato-3-hydroxy-1-aminopropane, 3-sulfato-2-hydroxy-1-aminopropane, 1-sulfato-3-hydroxy-2-aminopropane , 3-Hydroxy-1-sulfato-2-aminopropane, 2,3-disulfato-1-aminopropane or 1,3-disulfato-2-aminopropane, a derivative of these compounds with another ester group mentioned above instead of that Sulfato group, especially N- (2-sulfatoethyl) piperazine sulfate.
Darüberhinaus sind für die Modifizierung von Rohbaumwollartikeln auch solche Aminoverbindungen geeignet, die als reaktiven Rest an der Aminkomponente eine α-Chlor-β-hydroxy-Substitution aufweisen. Weiterhin können auch solche Verbindungen eingesetzt werden, die mit Hydroxylgruppen, beispielsweise von Cellulose, oder Amino- und Thiolgruppen, beispielsweise von Wolle und Seide, reagieren können und eine kovalente chemische Bindung einzugehen vermögen.In addition, those amino compounds that have an α-chloro-β-hydroxy substitution as a reactive residue on the amine component are also suitable for the modification of raw cotton articles. Furthermore, it is also possible to use compounds which can react with hydroxyl groups, for example cellulose, or amino and thiol groups, for example wool and silk, and which are capable of forming a covalent chemical bond.
Das Modifizieren während des Beuchens oder des Abkochens von Rohbaumwollartikeln kann kontinuierlich oder diskontinuierlich erfolgen. Als Beuch- oder Abkochflüssigkeit verwendet man in diskontinuierlicher Arbeitsweise Natronlauge mit etwa 5 bis 30 g/l NaOH. Man arbeitet vorzugsweise in geschlossenen Kesseln bei Temperaturen zwischen 80°C und 120°C, vorzugsweise 90 und 102°C. Das Vorbehandlungsagens kann linear, degressiv oder direkt zugegeben werden. Die Konzentrationen betragen zwischen 10 und 100 g/l, vorzugsweise 15 bis 30 g/l.The modification during the brewing or boiling of raw cotton articles can be carried out continuously or discontinuously. Soda lye with about 5 to 30 g / l NaOH is used as the baking or decoction liquid in a batch process. It is preferably carried out in closed tanks at temperatures between 80 ° C and 120 ° C, preferably 90 and 102 ° C. The pretreatment agent can be added linearly, degressively or directly. The concentrations are between 10 and 100 g / l, preferably 15 to 30 g / l.
Das erfindungsgemäße Modifizieren in diskontinuierlicher Form kann sich direkt einem Bleichprozeß mit Wasserstoffperoxid anschließen, indem man die zur Vorbehandlung notwendigen Menge Alkali der Bleichlösung zusetzt, dabei überschüssiges Bleichmittel zerstört und dann das Modifizierungsagenz addiert. Dabei hat es sich als vorteilhaft erwiesen, wenn der Bleichlösung kein Peroxidstabilisator zugesetzt wird.The modification according to the invention in discontinuous form can directly follow a bleaching process with hydrogen peroxide by adding the amount of alkali required for the pretreatment to the bleaching solution, thereby destroying excess bleaching agent and then adding the modification agent. It has proven to be advantageous if no peroxide stabilizer is added to the bleaching solution.
Bei einer kontinuierlichen Verfahrensführung schwanken die Mengen an NaOH zwischen 5 bis 20 Gew.-%, bezogen auf das Gewicht der Ware, je nach Art der Energiezufuhr und Art des Flottenauftrages. Als Anlageeinrichtungen dienen der Stiefel, Rollenbetten, Breit- und Blitzdämpfer, Rollendämpfer, HT-Dämpfer, Conveyor, Umdock-Anlagen und Unterflottenverweilanlagen. Gerechnet auf das Warengewicht, werden zwischen 2 und 10 Gew.-%, vorzugsweise 3 und 8 Gew.-%, Modifizierungsagens eingesetzt.In a continuous process, the amounts of NaOH fluctuate between 5 to 20% by weight, based on the weight of the goods, depending on the type of energy supply and the type of fleet order. The boots, roller beds, wide and lightning dampers, roller dampers, HT dampers, Conveyor, docking facilities and sub-fleet dwellings. Based on the weight of the goods, between 2 and 10% by weight, preferably 3 and 8% by weight, of modification agent are used.
Auch hier kann sich das erfindungsgemäße Modifizieren direkt einem kontinuierlichen Bleichprozeß anschließen, indem man auf das vorgebleichte, noch stark feuchte Material eine gegenüber einer üblichen Flotte zwei bis dreifach aufgestärkte, alkalische Wirksubstanzlösung aufquetscht und die Ware anschließend einem Dämpfprozeß unterwirft. Der Lösung für die Vorbleiche sollte kein Stabilisator zugesetzt sein, um zu gewährleisten, daß nach dem Aufquetschen der stark alkalischen Modifizierungsflotte das Wasserstoffperoxid schnell zerstört wird und so keine Faserschädigungen auftreten.Here too, the modification according to the invention can directly follow a continuous bleaching process by squeezing an alkaline active substance solution which has been strengthened two to three times compared to a conventional liquor onto the pre-bleached, still very moist material and then subjecting the goods to a steaming process. No stabilizer should be added to the solution for the pre-bleaching in order to ensure that after squeezing the strongly alkaline modification liquor, the hydrogen peroxide is quickly destroyed and thus no fiber damage occurs.
Das textile Fasermaterial, das in das erfindungsgemäße Vorbehandlungsverfahren eingesetzt wird, kann in allen Verarbeitungszuständen, so als Garn, Flocke, Kammzug und Stückware (Gewebe) vorliegen.The textile fiber material that is used in the pretreatment process according to the invention can be present in all processing states, such as yarn, flake, sliver and piece goods (fabric).
Ein wesentlicher und überraschender Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß die Faserschädigung, die im Verlauf von Abkoch- oder Beuchprozessen immer auftritt, bei einer Vorbehandlung mit besagten Modifizierungsagenzien deutlich vermindert ist.An essential and surprising advantage of the method according to the invention is that the fiber damage that always occurs in the course of boiling or baking processes is significantly reduced during pretreatment with said modification agents.
Zum Modifizieren eignen sich ebenfalls Mercerisierprozesse. Die bevorzugte Ausführungsform ist ein Trockenmercerisieren, indem man auf das Gewebe eine Natronlauge von 22 bis 32° Be, vorzugsweise 24° Be, die im Liter zwischen 30 und 120 g Modifizierungsagens enthält, aufquetscht. Anschließend wird die Ware auf einem Spannrahmen mit Heißluft von 120°C übertrocknet. Nach einem Auswaschprozeß wird ein Material erhalten, das einen erhöhten Glanz zeigt und erfindungsgemäß salz- und alkalifrei gefärbt werden kann.Mercerization processes are also suitable for modification. The preferred embodiment is dry mercerization by squeezing a sodium hydroxide solution of 22 to 32 ° Be, preferably 24 ° Be, which contains between 30 and 120 g of modification agent per liter, onto the fabric. The goods are then over dried on a stenter with hot air at 120 ° C. After a wash-out process, a material is obtained which has an increased gloss and can be dyed free of salt and alkali according to the invention.
Einer andere Ausführungsform stellt die Imprägnierung mit heißer, modifizierungsagenshaltiger Flotte dar. Im Anschluß an die Heißimprägnierung durchläuft die Ware ein Walzenmercerisierabteil. Abweichend von gängigen Techniken sollte die Temperatur während der Quellung und in der anschließenden Stabilisierzone für eine längere Zeit zwischen 80 und 95°C gehalten werden.Another embodiment is the impregnation with hot, modification agent-containing liquor. Following the hot impregnation the goods pass through a roller marking compartment. Contrary to common techniques, the temperature should be kept between 80 and 95 ° C for a longer period during the swelling and in the subsequent stabilization zone.
Das erfindungsgemäße Färben der aminierten Baumwollfasern erfolgt analog bekannten Färbeweisen und Druckverfahren zum Färben und Bedrucken von Fasermaterialien mit wasserlöslichen textilen Farbstoffen und unter Anwendung der hierfür bekanntermaßen eingesetzten Temperaturbereiche und üblichen Farbstoffmengen. Der besondere Vorteil hierbei ist, daß für die Färbebäder, Klotzverfahren, Druckpasten und Ink-Jet-Formulierungen ein Zusatz von alkalisch wirkenden Verbindungen, wie sie üblicherweise zur Fixierung von faserreaktiven Farbstoffen benutzt werden, nicht nötig ist und des weiteren auch auf übliche Zusätze an Elektrolytsalzen verzichtet werden kann.The dyeing of the aminated cotton fibers according to the invention is carried out analogously to known dyeing methods and printing processes for dyeing and printing fiber materials with water-soluble textile dyes and using the temperature ranges and customary amounts of dye known to be used for this. The particular advantage here is that the dye baths, padding processes, printing pastes and ink-jet formulations do not require the addition of alkaline compounds, as are usually used for fixing fiber-reactive dyes, and furthermore also the usual additions of electrolyte salts can be dispensed with.
Färbeverfahren, die erfindungsgemäß eingesetzt werden können, sind beispielsweise die verschiedenen Ausziehverfahren, wie das Färben auf dem Jigger und auf der Haspelkufe oder das Färben aus langer und kurzer Flotte, das Färben in Jet-Färbemaschinen, das Färben nach Klotz-Kaltverweilverfahren oder nach einem Klotz-Heißdampf-Fixierverfahren.
Zu den erfindungsgemäß nutzbaren Färbeverfahren zählen auch die Drucktechniken, einschließlich des Ink-Jet-Printings und des Transferdruckes.Dyeing processes which can be used according to the invention are, for example, the various exhaust processes, such as dyeing on the jigger and on the reel runner or dyeing from a long and short liquor, dyeing in jet dyeing machines, dyeing by padding-cold dwelling or padding -Hot steam fixing process.
The dyeing methods which can be used according to the invention also include the printing techniques, including ink-jet printing and transfer printing.
Die Farbstoffe, die zum Färben der aminierten Baumwollfaser genutzt werden, sind im allgemeinen anionischer Natur. Besonders geeignet sind die faserreaktiven Textilfarbstoffe, die mit Hydroxylgruppen, beispielsweise von Cellulose, oder Amino- und Thiolgruppen, beispielsweise von Wolle und Seide, von synthetischen Polymeren, wie Polyamiden, oder auch modifizierten Polymeren, eben den aminierten Cellulosen, reagieren können und eine kovalente Bindung einzugehen vermögen. Als faserreaktive Komponente an den Textilfarbstoffen seien besonders der Sulfatoethylsulfonyl-, Vinylsulfonyl-, Chlortriazinyl-, Fluortriazinyl-, Trichlorpyrimidyl-, Difluorchlorpyrimidyl-, Dichlorchinoxalinyl-, Chlorpropylamidyl-, α-Bromacrylamidyl sowie Kombinationen dieser "Ankersysteme" genannt.The dyes used to dye the aminated cotton fiber are generally anionic in nature. The fiber-reactive textile dyes, which can react with hydroxyl groups, for example of cellulose, or amino and thiol groups, for example of wool and silk, of synthetic polymers, such as polyamides, or also modified polymers, namely the aminated celluloses, and a covalent bond are particularly suitable able to enter.

Unless otherwise stated, the parts given in the examples are parts by weight.
Baumwollköper (vorentschlichtet, rohweiß, Gewicht 200 g/kg) wird mit einer wäßrigen Flotte, die 60 Teile Sulfatoethylpiperazin, 100 Teile Natriumhydroxid, 5 Teile ®Hostapal FA (Handelsname eines nichtionischen Netz- und Waschmittels) und 6 Teile ®Ladit RBO in 1000 Teilen Wasser enthält, imprägniert. Die Flottenaufnahme bei dieser Behandlung beträgt ca. 150 %. Das Gewebe wird anschließend aufgedockt und 60 Minuten bei 95 bis 103°C belassen. Der Temperaturbehandlung schließt sich ein dreimaliger Waschvorgang, wobei die Waschlösung gegebenenfalls ein handelsübliches Tensid enthalten kann, bei Kochtemperatur an, um die auf dem Gewebe befindlichen wasserlöslichen Verunreinigungen zu entfernen. Nach Spülen mit warmem und kaltem Wasser wird das Baumwollmaterial getrocknet. Man erhält so ein textiles Gewebe mit einem Entschlichtungsgrad von 9 (Bewertung nach Tegewa) und einer Saughöhe von 6,5 cm nach 300 Minuten, das direkt in einem Färbeprozeß nach dem Klotz-Verfahren weiterverarbeitet werden kann. Hierzu wird eine wäßrige Farbstofflösung, die in 1000 Vol.-Teilen 20 Teile des Farbstoffs der Formel,
bekannt aus der Europäischen Patentanmeldung 158 233, Bsp. 1, und 3 Teile eines handelsüblichen nichtionogenen Benetzungsmittels gelöst enthält, mittels eines Foulards mit einer Flottenaufnahme von 80 %, bezogen auf das Gewicht des Gewebes, bei 25°C auf das Gewebe aufgebracht. Das mit der Farbstofflösung geklotzte Gewebe wird auf eine Docke aufgewickelt, in eine Plastikfolie gewickelt, während 4 Stunden bei 40 bis 50°C liegen gelassen und danach mit kaltem und heißem Wasser, das gegebenenfalls ein handelsübliches Tensid enthalten kann, und gegebenenfalls anschließend nochmals mit kaltem Wasser gespült und getrocknet. Es wird eine farbstarke, gleichmäßig gefärbte gelbe Färbung erhalten, die gute Allgemeinechtheiten, insbesondere gute Reib-und Lichtechtheiten, besitzt.Cotton twill (pre-desized, raw white, weight 200 g / kg) is mixed with an aqueous liquor containing 60 parts sulfatoethylpiperazine, 100 parts sodium hydroxide, 5 parts ®Hostapal FA (trade name of a nonionic wetting and detergent) and 6 parts ®Ladit RBO in 1000 parts Contains water, impregnated. The liquor intake with this treatment is approx. 150%. The tissue is then docked and left at 95 to 103 ° C for 60 minutes. The temperature treatment is followed by a three-time washing process, the washing solution optionally being able to contain a commercially available surfactant, at boiling temperature, in order to remove the water-soluble impurities present on the fabric. After rinsing with warm and cold water, the cotton material is dried.
