Description
Verfahren zur waschbeständigen Mattierung von Polyamidfasern Es ist bekannt, eine Mattierung von Cellulosefasern durch die Bildung eines Niederschlages durch chemische Umsetzung zweier Verbindungen auf der Faser zu erzielen. Dieses _Zweibadverfahren besitzt kaum noch praktische Bedeutung, (Weiß, »Spezial-und Hochveredlungsverfahren der Textilien aus Cellulose«, Verlag Springer, Wien, 1951, S. 181). Die so erzeugten Niederschläge eignen sich insbesondere nicht für die Mattierung von Polyamidfasern, da sie auf der Polyamidfaser, der praktisch jede Zellstruktur fehlt, nur durch Bindemittel zum Haften gebracht werden können. Der Zusatz solcher Bindemittel wirkt sich jedoch nachteilig auf den Griff aus. Die aus Polyamidfasern hergestellten Gewebe oder Gewirke werden durch solche Bindemittel härter im Griff.Process for the wash-resistant matting of polyamide fibers It is known, a matting of cellulose fibers by the formation of a precipitate by chemical conversion of two compounds on the fiber. This _The two-bath process has hardly any practical significance (white, »special and high-finishing process der Textilien aus Cellulose ", Verlag Springer, Vienna, 1951, p. 181). The so generated Precipitation is particularly unsuitable for matting polyamide fibers, because they are based on the polyamide fiber, which is practically lacking in any cell structure, only through binding agents can be made to stick. The addition of such binders has an effect, however detrimental to the handle. The woven or knitted fabrics made from polyamide fibers become harder to handle with such binders.
Gewisse Elektrolyte, wie z. B. Zinkchlorid, Calciumchlorid, Natriumthiosulfat, Aluminiumsulfat und Magnesiumsulfat, üben bei einer Einwirkung auf Polyamidfasern eine quellende Wirkung aus. (G. K. Me,cklenburgh, S. Shaw, H. W. Peters, »Diel Entwicklung der Fixierung und Ausrüstung von Nylongeweben, Reyon und Zellwolle« 32, S.475 [19541). Die Quellmittel allein machen zwar die Faser für verschiedene Reagentien aufnahmefähiger, ohne aber eine Mattierungswirkung hervorzurufen.Certain electrolytes, such as B. zinc chloride, calcium chloride, sodium thiosulfate, Aluminum sulfate and magnesium sulfate, exercise when exposed to polyamide fibers a swelling effect. (G. K. Me, cklenburgh, S. Shaw, H. W. Peters, “The Development the fixation and finishing of nylon fabrics, rayon and rayon "32, p.475 [19541). The swelling agents alone make the fiber more receptive to various reagents, but without causing a matting effect.
Es ist ferner bekannt, Fasern aus Polyamiden oder Polyurethanen zu mattieren bzw. aufzurauhen, indem man sie mit neutralen bzw. schwach sauer reagierenden Mitteln behandelt, welche imstande: sind, diese Polymerisate zu lösen, und die so angelösten polymeren Stoffe mit einem Fällungsmittel wieder auf die Faser zu fällen (niederländische Patentschrift 58 768).It is also known to add fibers made of polyamides or polyurethanes matting or roughening by mixing them with neutral or slightly acidic reactants Treated agents which are able to dissolve these polymers, and so to precipitate dissolved polymeric substances back onto the fiber with a precipitant (Dutch patent specification 58 768).
Es ist ferner auch die Quellung von Polyamidfasern mit Phenolen beschrieben, wobei eine Wärmenachbehandlung erfolgt und dabei z. B. durch Thoriumsalze und Acetate Pigmentfixierungen erfolgen. Die niederländische Patentschrift 53 628 beschreibt ein ähnliches Verfahren, wobei nach Quellung mit Phenol Polyamidfasern einer mehrfachen Nachbehandlung mit Zinnsalzen unterworfen werden zur Erzielung von Beschwerungen bis zu 100% und mehr. Schließlich soll nach der USA.-Patentschrift 2 671770 die Mattierung von. Polyamidfasern mit Kupfer- und Manganverbindungen vorgenommen werden.It is also the swelling of polyamide fibers with phenols is described, with a heat treatment is carried out and z. B. by thorium salts and acetates pigment fixations. The Dutch patent 53 628 describes a similar process in which, after swelling with phenol, polyamide fibers are subjected to multiple aftertreatment with tin salts in order to achieve weights of up to 100% and more. Finally, according to US Pat. No. 2,671,770, the matting of. Polyamide fibers are made with copper and manganese compounds.
Es wurde gefunden, daß sich Polyamidfasern waschbeständig mattieren lassen, indem man die Polyamidfasern mit einem quellend wirkenden Alkali- oder Erdalkalithiosulfat behandelt, sie anschließend einer Wärmebehandlung unterzieht und schließlich einer chemischen Nachbehandlung unterwirft, durch welche aus den Alkali- oder Erdalkalisalzen Mattierungspigmente erzeugt werden.It has been found that polyamide fibers have a washable matt finish by treating the polyamide fibers with a swelling alkali or alkaline earth thiosulfate treated, then subjected to a heat treatment and finally a subject to chemical aftertreatment, by means of which from the alkali or alkaline earth salts Matting pigments are generated.
Imprägniert man die Polyamidfaser mit einer Lösung eines dieser Salze, unterzieht die Faser anschließend einer üblichen Wärmebehandlung, wie z. B. Dampftrocknung und bzw. oder Heißluftfixierung, und behandelt schließlich mit einer Verbindung, die aus dem Quellungsmittel ein Pigment erzeugt, so werden diese mattierend wirkenden Pigmente zum Teil in die Faser eingelagert, zumindest aber oberflächlich inkrustiert, während die nur oberflächlich auf der Faser gebildeten Pigmente durch eine Nachwäsche leicht und ohne Beeinträchtigung des Mattierungseffektes entfernt werden. Das Verfahren eignet sich zur Erzeugung waschbeständiger Mattierungen auf Polyamidfasern in allen Verarbeitungszuständen. Da der Effekt beständig ist, können die mattierten Textilien beliebig weiterbehandelt, z. B. abgekocht, gewaschen und gefärbt werden. Die nach dem vorliegenden Verfahren erzielte Mattierung mindert gleichzeitig die Durchsichtigkeit der Fasern und ruft bei der Ausrüstung von Geweben oder Gewirken ein dichteres Warenbild hervor.If the polyamide fiber is impregnated with a solution of one of these salts, then subjects the fiber to a conventional heat treatment, such as e.g. B. Steam drying and / or hot air fixation, and finally treated with a compound, which produces a pigment from the swelling agent, these have a matt effect Pigments partially embedded in the fiber, but at least encrusted on the surface, while the pigments only formed superficially on the fiber after washing can be removed easily and without impairing the matting effect. The procedure is suitable for creating wash-resistant matt finishes on polyamide fibers in all Processing states. Since the effect is permanent, the matted textiles can further treated as required, e.g. B. boiled, washed and colored. The after The matting achieved with the present process simultaneously reduces the transparency of the fibers and creates a denser appearance when finishing woven or knitted fabrics emerged.
Das erfindungsgemäße Verfahren hat gegenüber dem bekannten Stand der Technik den Vorteil, daß das Arbeiten mit Lösungsmitteln, wie Methanol, Aceton, Chloralhydrat, Chlorhydrin und dergleichen Stoffen, deren teils unangenehme, teils schädliche physiologische Wirkungen bekannt sind, vermieden wird. Auch das Arbeiten mit den als bekannt angeführten Phenolen bzw. phenolartigen Verbindungen sowie mit 20%iger Ameisensäure und Schwermetallsalzen wird nach dem vorliegenden Verfahren vermieden. Die Beseitigung bzw. biologische Unschädlichmachung in Abwässern verursacht erhebliche Aufwendungen. Ein Lösen des Polyamidmaterials durch die eirfin= dungsgemäß verwendeten Mittel erfolgt nicht, so daß eine Schädigung-der Faser von vornherein ausbleibt,, L. das na@h:der voxliegenden.Erfindung vornehmlich vei-wendete Xätriumthiosiztfat nicht iri 'dem' Lage" igt,' eine lösende Wirk- ung auf die Polyamidfaser auszuüben.The inventive method has compared to the known prior art Technology has the advantage that working with solvents such as methanol, acetone, Chloral hydrate, chlorohydrin and the like substances, some of them unpleasant, some harmful physiological effects are known to be avoided. Working too with the phenols or phenol-like compounds listed as known as well as with 20% formic acid and heavy metal salts are used according to the present process avoided. The elimination or biological neutralization in wastewater causes significant expenses. A loosening of the polyamide material by the Eirfin = properly used agent does not occur, so that damage-the Fiber is absent from the start, L. das na @ h: the voxlying.Erfindung mainly Did not use xtrium thiosiztfate in the 'situation', 'a releasing effect to exercise on the polyamide fiber.
