Definitions
- the invention relates to a method for chemical fixing of wool. Sufficiently fixed yarns are necessary for the wet finishing and later wet cleaning of pure wool cut pile carpets for carpeting. This fixation serves to stabilize the yarn twist and the yarn build-up, in order to thereby prevent undesirable matting of the cut pole during the wet treatment. It is known to fix woolen yarns with sodium hydrogen sulfite by treating the yarns opened on the cheese or as a strand either on the yarn dyeing machine or in continuous plants. In order to achieve the fixing effect, the wool yarns are passed through a sodium hydrogen sulfite solution bath at 85 ° C., rinsed in a warm water bath after a desired retention time, and aftertreated if necessary with a hydrogen peroxide solution. Such a process is in "Chemical fibers / textile industry", 40./92. Volume, September 1990, pages 900 to 905.
- the invention has for its object to provide a method for the chemical fixing of wool for the production of carpet pieces as carpeting, with which it is possible to achieve a desired fixation of the cut pole of a carpet piece in a carpet piece.

- a knitted fabric or a cut pile carpet piece is fixed according to the invention, the knitted fabric being a preliminary product for the production of a piece of carpet.
- the knitted fabric can be produced in particular as a knitted tube and is thus fixed. In this way, twine bends and twists are fixed in a targeted and even manner, which later create a corresponding, desired surface appearance in the finished pile pile carpet. For this purpose, the knitted tube is drawn back into the yarn after fixing, which is then used to produce a cut pile carpet piece.
- the fixation of the yarn in the knitted tube can be more or less strong, depending on whether the carpet piece woven with the yarn fixed in the knit piece is fixed again or not.
- the knitted piece or piece of carpet can preferably be treated with a sodium bisulfite solution at a concentration of 10 to 100 g / l.
- the knitted piece or piece of carpet can be soaked by immersing in the bath or by pouring the solution over it if the knitted piece or piece of carpet is to be fixed over the entire surface.

- This fixation of the knitted piece or piece of carpet can be carried out in the usual way with hot sodium bisulfite solution and then repeated rinsing in hot water, but the treatment is preferably carried out in the form that the knitted piece or carpet piece is saturated with sodium bisulfite solution at a temperature of 30 ° to 40 ° C. and the actual fixing is carried out by a subsequent treatment with saturated steam or superheated steam, which is then followed by rinsing with water and, if appropriate, a further treatment with hydrogen peroxide.
Abstract
Description
Die Erfindung betrifft ein Verfahren zum chemischen Fixieren von Wolle. Für die Naßveredlung und die spätere Naßreinigung von reinen Wollschnittpolteppichen für Auslegeware sind ausreichend fixierte Garne notwendig. Diese Fixierung dient dazu, die Garndrehung und den Garnaufbau zu stabilisieren, um dadurch ein unerwünschtes Verfilzen des Schnittpols während der Naßbehandlung zu verhindern. Es ist bekannt, Wollgarne mit Natriumhydrogensulfit zu fixieren, indem die Garne aufgemacht auf der Kreuzspule oder als Strang entweder auf dem Garnfärbeapparat oder auch in kontinuierlichen Anlagen behandelt werden. Um den Fixiereffekt zu erreichen, werden die Wollgarne durch ein 85° C warmes Natriumhydrogensulfit-Lösungsbad geführt, nach einer entsprechend der gewünschten Fixierung bemessenen Verweilzeit im warmen Wasserbad gespült und ggf. mit einer Wasserstoffperoxidlösung nachbehandelt. Ein derartiges Verfahren ist in "Chemiefasern/Textilindustrie", 40./92. Jahrgang, September 1990, Seiten 900 bis 905 beschrieben.The invention relates to a method for chemical fixing of wool. Sufficiently fixed yarns are necessary for the wet finishing and later wet cleaning of pure wool cut pile carpets for carpeting. This fixation serves to stabilize the yarn twist and the yarn build-up, in order to thereby prevent undesirable matting of the cut pole during the wet treatment. It is known to fix woolen yarns with sodium hydrogen sulfite by treating the yarns opened on the cheese or as a strand either on the yarn dyeing machine or in continuous plants. In order to achieve the fixing effect, the wool yarns are passed through a sodium hydrogen sulfite solution bath at 85 ° C., rinsed in a warm water bath after a desired retention time, and aftertreated if necessary with a hydrogen peroxide solution. Such a process is in "Chemical fibers / textile industry", 40./92. Volume, September 1990, pages 900 to 905.
Nachteilig ist bei der bekannten Garnfixierung auf der Kreuzspule und im Strang, daS sich sog. "Krückstöcke" bilden können, das sind ungleichmäßig und bogenförmig fixierte Garnabschnitte, die sich auf das Erscheinungsbild des fertigen Teppichstücks nachteilig auswirken können. Des weiteren kann sich eine Streifigkeit im Schnittpolteppich ergeben, da durch die diskontinuierlichen und kontinuierlichen Garnfixierungsverfahren Ungleichmäßigkeiten in der Farbstoffaffinität durch Unterschiede in der Fixierung auftreten können.A disadvantage of the known yarn fixation on the Cross-wound bobbin and in the skein that so-called "crutches" can form, these are unevenly and arch-shaped fixed yarn sections, which can have an adverse effect on the appearance of the finished piece of carpet. Furthermore, streaking can occur in the cut pile carpet, since discontinuous and continuous yarn fixation processes can cause nonuniformities in dye affinity due to differences in fixation.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum chemischen Fixieren von Wolle für die Herstellung von Teppichstücken als Auslegeware zu schaffen, mit dem es möglich ist, bei einem Teppichstück eine gewünschte Fixierung des Schnittpols eines Teppichstücks zu erreichen. Mit dieser Fixierung soll ein gewünschtes Oberflächenbild erreicht werden, das von einem völlig gleichmäßigen, streifenfreien Schnittpol bis zu einer gewünschten, vorgebbaren Oberflächenstruktur und einem gewünschten und vorgebbaren Oberflächenbild gehen können soll.The invention has for its object to provide a method for the chemical fixing of wool for the production of carpet pieces as carpeting, with which it is possible to achieve a desired fixation of the cut pole of a carpet piece in a carpet piece. This fixation is intended to achieve a desired surface appearance, which should be able to go from a completely uniform, streak-free cut pole to a desired, predefinable surface structure and a desired and predefinable surface appearance.
Ausgehend von dieser Aufgabenstellung wird bei einem Verfahren der eingangs erwähnten Art vorgeschlagen, daß die Wolle erfindungsgemäß als Maschenware und/oder Schnittpolteppichstück fixiert wird. Die Maschenware kann gestrickt, gewirkt, geraschelt oder gehäkelt sein und muß das Auflösen des Garns aus dem Verbund zulassen. Verfahren zum chemischen Fixieren von Wolle als Maschenware sind aus den Dokumenten GB-A-501 292, US-A-3 062 610, GB-A-1 543 720 und "Journal of the Textile Institute", Bd.55, Nr.10, 1964, Manchester, GB, Seiten T512-T515 bekannt. Im Gegensatz zu den bekannten Garnfixierverfahren wird erfindundsgemäß eine Maschenware oder ein Schnittpolteppichstück fixiert, wobei die Maschenware ein Vorprodukt zur Herstellung eines Teppichstücks ist.Based on this task, it is proposed in a method of the type mentioned at the outset that the wool is fixed according to the invention as a knitted fabric and / or cut pile carpet piece. The knitted fabric can be knitted, knitted, rustled or crocheted and must allow the yarn to dissolve from the composite. Methods for chemically fixing wool as knitwear are described in documents GB-A-501 292, US-A-3 062 610, GB-A-1 543 720 and "Journal of the Textile Institute", Vol. 55, No. 10 , 1964, Manchester, GB, pages T512-T515. In contrast to the known yarn fixing methods, a knitted fabric or a cut pile carpet piece is fixed according to the invention, the knitted fabric being a preliminary product for the production of a piece of carpet.
Die Maschenware läßt sich insbesondere als Strickschlauch herstellen und wird so fixiert. Auf diese Weise werden gezielt und gleichmäßig Garnbögen und Garnkrümmungen fixiert, die später im fertiggestellten Schnittpolteppich ein entsprechendes, gewünschtes Oberflächenbild erzeugen. Zu diesem Zweck wird der Strickschlauch nach dem Fixieren wieder zum Garn aufgezogen, das dann zum Herstellen eines Schnittpolteppichstücks verwendet wird.The knitted fabric can be produced in particular as a knitted tube and is thus fixed. In this way, twine bends and twists are fixed in a targeted and even manner, which later create a corresponding, desired surface appearance in the finished pile pile carpet. For this purpose, the knitted tube is drawn back into the yarn after fixing, which is then used to produce a cut pile carpet piece.
Die Fixierung des Garns im Strickschlauch kann mehr oder weniger stark sein, je nachdem, ob das mit dem im Strickstück fixierten Garn gewebte Teppichstück erneut fixiert wird oder nicht.The fixation of the yarn in the knitted tube can be more or less strong, depending on whether the carpet piece woven with the yarn fixed in the knit piece is fixed again or not.
Das Strickstück oder Teppichstück kann vorzugsweise mit einer Natriumhydrogensulfitlösung mit einer Konzentration von 10 bis 100 g/l behandelt werden.The knitted piece or piece of carpet can preferably be treated with a sodium bisulfite solution at a concentration of 10 to 100 g / l.
Das Strickstück oder Teppichstück kann durch Tauchen im Bad oder durch Übergießen mit der Lösung getränkt werden, wenn das Strickstück oder Teppichstück ganzflächig fixiert werden soll. Es ist jedoch auch möglich, das Strickstück oder Teppichstück mit der Lösung ganzflächig oder bereichsweise zu bedrucken, wobei zum Bedrucken Rolleauxdruckwalzen, Filmschablonen oder die Spritzdrucktechnik verwendbar sind. Für das Bedrucken kann eine vorzugsweise mittels synthetischer Polymere viskos eingestellte Lösung verwendet werden.The knitted piece or piece of carpet can be soaked by immersing in the bath or by pouring the solution over it if the knitted piece or piece of carpet is to be fixed over the entire surface. However, it is also possible to print the solution over the entire surface or in some areas of the knitted piece or carpet piece, roller-printing rollers, film stencils or the spray-printing technique being used for the printing. For printing, a viscous one, preferably by means of synthetic polymers, can be used Solution can be used.
Die Behandlung mit Natriumhydrogensulfitlösung kann bei einer Temperatur zwischen 20° und 90° C erfolgen, und das Strickstück oder Teppichstück wird nach der Behandlung mit Natriumhydrogensulfitlösung mit Wasser gespült, wodurch entsprechend der Gleichgewichtsreaktion Cystinbindungen rückgeformt werden und damit wieder eine Stabilisierung des Molukulargefüges erreicht wird. Dieser Effekt läßt sich verstärken durch eine anschließende Behandlung mit Wasserstoffperoxid, da es sich bei dieser Rückformung der Cystinbindungen um eine Oxidation handelt.The treatment with sodium hydrogen sulfite solution can take place at a temperature between 20 ° and 90 ° C, and the knitted piece or carpet piece is rinsed with water after the treatment with sodium hydrogen sulfite solution, whereby cystine bonds are reformed in accordance with the equilibrium reaction and the molecular structure is stabilized again. This effect can be intensified by subsequent treatment with hydrogen peroxide, since this reforming of the cystine bonds is an oxidation.
Besonders vorteilhaft läßt sich das erfindungsgemäße Verfahren durchführen, wenn das Strickstück oder Teppichstück mit einer Natriumhydrogensulfitlösung bei 20° bis 40° C getränkt und anschließend, vorzugsweise mit Sattdampf von 95° C gedämpft wird. Auf diese Weise dient die Behandlung mit der Natriumhydrogensulfitlösung im wesentlichen zum Tränken des Strickstücks oder Teppichstücks mit der Lösung, ohne daß bereits eine wesentliche chemische Einwirkung auf die Wolle erfolgt. Diese chemische Einwirkung wird durch das Dämpfen mit Sattdampf bei mindestens 95° C erreicht, wobei die Reaktion schneller, intensiver und gleichmäßiger abläuft, da der Dampf bis in die tiefsten Poren des Strickstücks oder Teppichstücks dringt und mit einer höheren Temperatur einwirkt als dies in einem Bad möglich ist.The process according to the invention can be carried out particularly advantageously if the knitted piece or piece of carpet is impregnated with a sodium bisulfite solution at 20 ° to 40 ° C. and then steamed, preferably with saturated steam at 95 ° C. In this way, the treatment with the sodium bisulfite solution essentially serves to impregnate the knitted piece or piece of carpet with the solution without the wool having a substantial chemical effect. This chemical effect is achieved by steaming with saturated steam at a temperature of at least 95 ° C, whereby the reaction proceeds faster, more intensely and more evenly, since the steam penetrates into the deepest pores of the knitted piece or piece of carpet and acts at a higher temperature than in a bath is possible.
Da das Bad mit der Natriumhydrogensulfitlösung praktisch bei Raumtemperatur gehalten wird, ist mit dem erfindungsgemäßen Verfahren auch eine Energieersparnis verbunden.Since the bath with the sodium bisulfite solution is practically kept at room temperature, the method according to the invention also results in energy savings.
Durch das Dämpfen, das sich an das Behandeln mit Natriumhydrogensulfitlösung anschließt, ergibt sich überraschenderweise eine erhebliche Steigerung der Fixiereffekte, die ausschließlich von der Dampftemperatur und der Dämpfzeit abhängen. Bei einer Sattdampftemperatur von mindestens 95° C ist eine Dämpfzeit von mindestens drei Minuten in der Regel ausreichend.Steaming, which follows treatment with sodium bisulfite solution, surprisingly results in a considerable increase in the fixing effects, which depend exclusively on the steam temperature and the steaming time. With a saturated steam temperature of at least 95 ° C, a steaming time of at least three minutes is usually sufficient.
Das erfindungsgemäße Verfahren ist vorzugsweise für eine kontinuierliche Behandlung des Strickstücks oder Teppichstücks im Durchlaufverfahren geeignet. Hierzu kann das Strickstück oder Teppichstück in einem ersten Bad mit einer Natriumhydrogensulfitlösung von 10 bis 100 g/l bei einer Temperatur von 20° bis 90° C, vorzugsweise von 30° bis 40° C getränkt werden. Die Konzentration der Natriumhydrogensulfitlösung richtet sich nach der Beschaffenheit des Garns und der gewünschten Stärke der Fixierung. Das Tränken mit der Lösung kann vorzugsweise im Foulard erfolgen. Beim Verlassen des ersten Bades wird das Strickstück oder Teppichstück durch Quetschwalzen geführt, um den Gehalt des Strickstücks oder Teppichstücks an Natriumhydrogensulfitlösung einzustellen. Danach gelangt das Strickstück oder Teppichstück in einen Tunnel, der mit Sattdampf von mindestens 95° C beaufschlagt ist. Diesen Dämpftunnel durchläuft das Strickstück oder Teppichstück mit einer Verweildauer von mindestens drei Minuten, um danach durch zwei aufeinanderfolgende Spülbäder mit an deren Ausgängen angeordneten Quetschwalzen geführt, anschließend ggf. mit Wasserstoffperoxid behandelt und schließlich getrocknet zu werden.The method according to the invention is preferably suitable for a continuous treatment of the knitted piece or piece of carpet in a continuous process. For this purpose, the knitted piece or piece of carpet can be soaked in a first bath with a sodium bisulfite solution of 10 to 100 g / l at a temperature of 20 ° to 90 ° C., preferably 30 ° to 40 ° C. The concentration of the sodium bisulfite solution depends on the nature of the yarn and the desired strength of the fixation. The impregnation with the solution can preferably take place in the padder. When leaving the first bath, the knitted piece or carpet piece is passed through squeeze rollers in order to adjust the content of sodium bisulfite solution in the knitted piece or carpet piece. The knitted piece or piece of carpet then enters a tunnel which is saturated with steam of at least 95 ° C. The knitted piece passes through this steam tunnel or piece of carpet with a dwell time of at least three minutes, after which it is then passed through two successive rinsing baths with squeeze rollers arranged at their outputs, then optionally treated with hydrogen peroxide and finally dried.
Statt das Strickstück oder Teppichstück durch einen Foulard zu führen, kann das Strickstück oder Teppichstück bereichsweise mit Natriumhydrogensulfitlösung bedruckt werden. Auf diese Weise läßt sich durch die bereichsweise Fixierung ein gewünschtes Oberflächenbild erzeugen. Der Auftrag der Natriumhydrogensulfitlösung kann über Rolleauxdruckwalzen, durch Filmschablonen oder in Spritzdrucktechnik erfolgen, wobei die Natriumhydrogensulfitlösung aus drucktechnischen Gründen viskos vorzugsweise mittels synthetischer Polymere eingestellt wird. Das bereichsweise Fixieren durch Bedrucken erfordert ein Vorfixieren, entweder durch Verwendung von insbesondere im Strickstück fixierten Garnen oder durch vorheriges vollflächiges Fixieren; es kann jedoch auch ein vollflächiges Nachfixieren vorgesehen werden, bei dem ggf. auf ein Dämpfen verzichtet werden kann, wenn das Teppichstück mit einer Natriumhydrogensulfitlösung von mindestens 80° C behandelt wird, wobei die Behandlung durch Tauchen in einem Bad oder durch Übergießen mit der heißen Natriumhydrogensulfitlösung erfolgen kann. Durch ein vollflächiges Nachfixieren läßt sich eine Steifigkeit des Teppichstücks, die aus unterschiedlicher Fixierung der verwendeten Garne und daraus resultierender unterschiedlicher Farbaffinität beim Bedrucken oder Färben entstehen kann, vermeiden. Beim Nachfixieren kann eine Konzentration der Natriumhydrogensulfitlösung von weniger als 10 g/l ausreichend sein.Instead of leading the knitted piece or piece of carpet through a foulard, the knitted piece or piece of carpet can be printed with sodium hydrogen sulfite solution in some areas. In this way, a desired surface image can be generated by the area-specific fixation. The application of the sodium bisulfite solution can take place over roller printing rollers, through film stencils or in spray printing technology, the sodium bisulfite solution being adjusted viscous, preferably by means of synthetic polymers, for reasons of printing technology. The area-by-area fixing by printing requires a pre-fixing, either by using yarns fixed in particular in the knitted piece or by previous full-surface fixing; However, full-surface post-fixing can also be provided, in which case steaming may be omitted if the piece of carpet is treated with a sodium hydrogen sulfite solution of at least 80 ° C., the treatment being carried out by immersion in a bath or by pouring the hot sodium hydrogen sulfite solution over it can be done. Through a full-surface post-fixation, the stiffness of the carpet piece can result from the different fixation of the yarns used and the resulting different color affinity when printing or dyeing avoid. A concentration of the sodium bisulfite solution of less than 10 g / l may be sufficient for subsequent fixation.
Im Rahmen der vorliegenden Erfindung ist es wesentlich, daß bei der Herstellung von Teppichstücken als Auslegware wenigstens eine Fixierbehandlung eines Strickstücks und/oder Teppichstücks erfolgt, unabhängig davon, ob beim Weben des Teppichstücks nach bekannten Verfahren fixierte Garne eingesetzt werden. Dieses Fixieren des Strickstücks oder Tepppichstücks läßt sich in üblicher Weise mit heißer Natriumhydrogensulfitlösung und anschließendem mehrfachen Spülen in heißem Wasser durchführen, jedoch erfolgt die Behandlung bevorzugterweise in der Form, daß das Strickstück oder Teppichstück mit Natriumhydrogensulfitlösung bei einer Temperatur von 30° bis 40° C getränkt wird und das eigentliche Fixieren durch eine anschließende Behandlung mit Sattdampf oder überhitztem Dampf erfolgt, woran sich dann ein Spülen mit Wasser und ggf. eine weitere Behandlung mit Wasserstoffperoxid anschließt.In the context of the present invention, it is essential that at least one fixing treatment of a knitted piece and / or piece of carpet takes place in the manufacture of carpet pieces as carpeting, regardless of whether fixed yarns are used in the weaving of the carpet piece by known methods. This fixation of the knitted piece or piece of carpet can be carried out in the usual way with hot sodium bisulfite solution and then repeated rinsing in hot water, but the treatment is preferably carried out in the form that the knitted piece or carpet piece is saturated with sodium bisulfite solution at a temperature of 30 ° to 40 ° C. and the actual fixing is carried out by a subsequent treatment with saturated steam or superheated steam, which is then followed by rinsing with water and, if appropriate, a further treatment with hydrogen peroxide.
