Description
Herzog hat in der Zeitschrift »Kunststoffe« vom i. Mai 1913 die Wirkung feuchter Wärme auf Acetatseide beschrieben und dabei festgestellt, daß bei höherer Temperatur ein opakes, milchiges Aussehen, begleitet von erheblicher Volumenvermehrung, erbalten wird.Herzog wrote in the magazine »Kunststoffe« from i. May 1913 the effect of moist heat on acetate silk and found that at a higher temperature an opaque, milky appearance, accompanied by a considerable increase in volume, is inherited.
Die gleiche Erscheinung beobachtet man gelegentlich, wenn man Gewebe, die Acetatseide allein oder im Gemisch mit anderen Fasern enthalten, einer Behandlung unterwirft, die wie das Entleimen und Entfärben in heißem Wasser in Gegenwart von Seife oder Säuren vorgenommen wird. Die Acetatseide nimmt unter diesen Umständen das Aussehen und den Griff von Wolle an, und man hat deshalb verschiedene Verfahren vorgeschlagen, um diese Erscheinung absichtlich hervorzurufen. So ist beispielsweise vorgeschlagen worden, Acetatseide mittels Lösungen von Salzen oder von Essigsäure zu mattieren und wollähnlich zu machen. Bei diesem bekannten Verfahren sollen 15 bis 3O°/0ige Lösungen der Alkalisulfo-The same phenomenon is occasionally observed when fabrics containing acetate silk, alone or in admixture with other fibers, are subjected to a treatment such as desizing and bleaching in hot water in the presence of soap or acids. The acetate silk takes on the look and feel of wool under these circumstances and various methods have therefore been proposed for deliberately producing this appearance. For example, it has been proposed to matt acetate silk by means of solutions of salts or of acetic acid and to make it wool-like. In this known method are 15 to 3O ° / 0 solutions of the Alkalisulfo-

cyanide oder 20 bis 35 %ige Lösungen der Essigsäure in der Kälte benutzt werden. Diese Behandlungsweise ruft eine ausgesprochene Längsverkürzung der Fasern hervor, die auf das starke Peptisationsvermögen dieser Chemikalien für Celluloseacetatseide zurückzuführen ist. Bei der Anwendung dieser Chemikalien, die in der Hitze in den angegebenen Konzentrationen ausgesprochene Lösungsmittel für Celluloseacetat sind, war stets das Eintreten einer Faserschädigung zu befürchten.cyanide or 20 to 35% solutions of acetic acid can be used in the cold. This way of treatment causes a pronounced longitudinal shortening of the fibers, which is due to the strong peptization capacity of these chemicals for Cellulose acetate silk is due. When applying these chemicals found in solvents for cellulose acetate pronounced under the heat in the specified concentrations fiber damage was always to be feared.
Es ist nun festgestellt worden, daß kochende Lösungen von Mineralsäuren und von organischen Säuren bei starker Verdünnung (z. B. Vio normal, V50 normal, V100 normal) auf Acetylcelluloseseide eine kräftige mattierende Wirkung ausüben.It has now been established that boiling solutions of mineral acids and of organic Strongly diluted acids (e.g. Vio normal, V50 normal, V100 normal) on acetylcellulose silk have a powerful mattifying effect.
Es ist ferner beobachtet worden, daß das Aussehen des mattierten Fadens je nach der Art der verwendeten Säure wesentlich verschieden ausfällt, wie aus folgenden Beispielen hervorgeht:It has also been observed that the appearance of the matted thread varies depending on the The type of acid used is significantly different, as shown in the following examples it emerges:

Diese stark verdünnten, siedenden Säurelösungen dürfen aber trotz der angegebenen bemerkenswerten Ergebnisse nicht ohne weiteres verwendet werden, denn sobald man ein regelmäßiges mattes Aussehen erzielen will, tritt eine wesentliche Verminderung der Elastizität ein, in gewissen Fällen sogar derart, daß die Fäden oder Gewebe zum Gebrauch ungeeignet werden.These very dilute, boiling acid solutions may, however, despite the specified Noteworthy results cannot be readily used because once you get a regular one want to achieve a matt appearance, there is a significant reduction in elasticity, in certain cases even such that the threads or fabrics are unsuitable for use will.
ίο Die vorliegende Erfindung betrifft ein Verfahren zur Verwendung der verschiedenartigen, rasch eintretenden, mattierenden Einwirkung von sehr verdünnten kochenden wäßrigen Säurelösungen auf Acetylcellulosefasern, ohne dabeiThe present invention relates to a method for the use of the various, rapidly occurring, mattifying effects from very dilute boiling aqueous acid solutions to acetyl cellulose fibers without doing so
X5 die Güte der behandelten Fasern zu vermindern. X5 to reduce the quality of the treated fibers.
Dieser Zweck wird erreicht, wenn man die Fäden aus Acetylcellulose oder die solche Fäden enthaltenden Gewebe bei gewöhnlicher Temperatur in eine wäßrige Lösung von Calcium-, Lithium- oder Magnesiumchlorid von io bis 3O°/0, und zwar 2 bis 24 Stunden lang, taucht, worauf man die Fäden oder Gewebe 1 bis 20 Minuten lang mit einem siedenden wäßrigen Säurebad behandelt, dessen Konzentration sich je nach der verwendeten Säure ändern kann, die aber n/10 nicht übersteigt.This purpose is achieved if the filaments of acetylcellulose or the threads such tissue containing at ordinary temperature in an aqueous solution of calcium, lithium or magnesium chloride from io to 3O ° / 0, namely 2 to 24 hours, immersed, whereupon the threads or fabrics are treated for 1 to 20 minutes with a boiling aqueous acid bath, the concentration of which may vary depending on the acid used, but which does not exceed n / 10.
Bei diesem Verfahren wird die obenerwähnte Mattierung in sehr regelmäßiger Weise erhalten, ohne daß die Faser leidet; sie verliert nichts von ihren mechanischen Eigenschaften, im besondern bleibt der Dehnungscoefficient praktisch unverändert.In this process, the above-mentioned matting is obtained in a very regular manner, without the fiber suffering; it does not lose any of its mechanical properties, in particular, the expansion coefficient remains practically unchanged.
Die Wirkung der Chloride des Magnesiums und des Lithiums ist sehr ähnlich derjenigen des Chlor calciums, soweit es das vorliegende Verfahren betrifft; alles, was in der Folge vom Calciumchlorid gesagt wird, gilt auch von den zwei anderen Chloriden.The action of the chlorides of magnesium and lithium is very similar to that calcium chlorine as far as the present process is concerned; everything that follows from Calcium chloride is said to be true of the other two chlorides as well.
Wenn die Fäden oder Gewebe aus Acetylcellulose nach der Behandlung im kalten Chlorcalciumbad gespült und ohne Streckung getrocknet werden, behalten sie den Glanz und den Griff der ursprünglichen Faser.If the threads or fabrics are made of acetyl cellulose Rinsed in a cold calcium chloride bath after treatment and without stretching When dried, they retain the shine and feel of the original fiber.
Die wäßrige Chlorcalciumlösung braucht nicht io%ig zu sein, um den gewünschten Effekt zu erzielen; die Konzentration zwischen 10 und 30% wird aber vorgezogen, da so gleichmäßigere Ergebnisse erhalten werden.The aqueous calcium chloride solution does not need io% ig to get the effect you want to achieve; the concentration between 10 and However, 30% is preferred because it gives more uniform results.
Je stärker die Fäden gedreht sind und je dichter die Gewebe sind, desto langer muß man sie im Chlorcalciumbad belassen.The more the threads are twisted and the denser the fabric, the longer it has to be leave them in the calcium chloride bath.
Was die Konzentration der Säurebäder betrifft, so kann man im allgemeinen beobachten, daß die günstigste Konzentration für Mineralsäuren, obschon sie nicht n/10 übersteigt, doch höher ist als diejenige der organischen Säuren, für die oft ein Gehalt von n/100 oder noch weniger genügt.As regards the concentration of the acid baths, one can generally observe that the most favorable concentration for mineral acids, although not exceeding n / 10, is is higher than that of organic acids, for which often a content of n / 100 or even more less is enough.
Bei dieser Behandlung tritt keinerlei Desacetylierung der Faser ein; das Verhalten gegenüber Farbstoffen bleibt durchaus dasjenige der Acetylcellulose. No deacetylation of the fiber occurs during this treatment; the behavior towards The color of acetyl cellulose is definitely the same.
Das Verfahren ist vom wirtschaftlichen Standpunkt aus sehr bemerkenswert; infolge der starken Verdünnung der Säurebäder werden nämlich die Verluste und Belästigungen durch Verdampfung der flüchtigen Säuren auf ein Minimum erniedrigt, abgesehen von den verminderten Ausgaben für Säure. Andrerseits ermöglicht die kurze Dauer der Behandlung eine bessere Ausnutzung der Einrichtung; diese wird zudem sehr wenig angegriffen.The process is very remarkable from an economic point of view; as a result of strong dilution of the acid baths will namely reduce the losses and nuisances caused by Evaporation of the volatile acids is reduced to a minimum, apart from the diminished Spending on acid. On the other hand, the short duration of the treatment makes it possible a better use of the facility; this is also very little attacked.
Ein Satin mit Kette aus Acetylcellulose und Einschlag aus Baumwolle wird nach Entleimen 12 Stunden lang in eine Chlorcalciumlösung von 30°/,, eingelegt und dann ausgedrückt. Man behandelt darauf 20 Minuten lang mit kochender Borsäure n/10. Nach dem Spülen und Trocknen hat der Satin ein mattes, ganz besonderes perlmutterartiges Aussehen angenommen, ohne daß die Festigkeit sich ver- 8s ringert hätte.A satin with a chain made of acetyl cellulose and a cotton wrap is made after de-glueing Immerse in a 30% calcium chloride solution for 12 hours and then squeezed out. It is then treated with boiling boric acid n / 10 for 20 minutes. After rinsing and drying, the satin has a dull, quite assumed a special mother-of-pearl-like appearance without losing strength would have wrestled.
Ein Samt, dessen Haar (Flor) aus Acetylcellulose besteht, wird während 4 Stunden in ein 20°/Oiges Chlorcalciumbad gelegt; hiernach wird die Ware ausgedrückt und während 10 Minuten in eine kochende n/100 Benzoesäurelösung getaucht. Der Samt wird dann matt, und diese Mattheit bleibt nach allen für Acetylcellulose gebräuchlichen Färbeoperationen erhalten. A velvet, consists whose hair (Flor) made of acetyl cellulose is placed for 4 hours in a 20 ° / o sodium Chlorcalciumbad; then the product is squeezed out and immersed in a boiling n / 100 benzoic acid solution for 10 minutes. The velvet then becomes dull, and this dullness is retained after all dyeing operations customary for acetyl cellulose.
Ein Krepp mit Acetatkette und Seideneinschlag wird nach dem Entlehnen während 24 Stunden in ein Chlorcalciumbad von io°/0 gelegt, gewaschen und geschleudert; darauf behandelt man während 15 Minuten mit einer kochenden n/100 Lösung von ß-Naphthalinsulfosäure. Das Gewebe nimmt so ein sehr gleichmäßiges mattes Aussehen an, der Griff wird wollig und äußerst weich und warm. Man kann nach allen bekannten Verfahren färben.After borrowing, a crepe with an acetate chain and silk wrap is placed in a calcium chloride bath of 10 ° / 0 for 24 hours, washed and spun; then treated for 15 minutes with a boiling n / 100 solution of ß-naphthalenesulfonic acid. The fabric takes on a very even, matt appearance, the handle becomes woolly and extremely soft and warm. You can dye by all known methods.
Ein! Strang von Acetylseide wird 5 Stunden lang in eine wäßrige io°/oige Chlorcaleiumlösung gelegt und darauf geschleudert; man taucht den Strang dann 20 Minuten lang in eine kochende, 1Z10 normale Salzsäure. Die Seide hat ein milchiges und perlmutterartiges Aussehen angenommen, sie hat aber ihre Festigkeit und ihre färberischen Eigenschaften beibehalten.A! Strand of Acetylseide is set long for 5 hours in an aqueous io ° / o and spun strength Chlorcaleiumlösung thereon; the strand is then immersed in boiling 1 Z 10 normal hydrochloric acid for 20 minutes.

Die Seide ist matt geworden und hat eine bräunliche Färbung, ähnlich der des Kamelhaars, angenommen.ι kg of acetate silk is placed in an aqueous solution of 20% calcium chloride for 8 hours. It is spun and immersed for 15 minutes in a boiling solution of 1 Z 20 normal pyrogallic acid. It is rinsed with water, spun and dried in a stream of warm air at 70 °. The silk has become dull and has taken on a brownish color, similar to that of camel's hair.
Ein Gewebe von Leinwandbindung, dessen Kette und Einschlag aus Acetatseide bestehen, wird 3 Stunden lang in eine wäßrige Lösung gelegt, die io°/0 Chlorcalcium enthält; man spült und quetscht, taucht dann 10 Minuten in eine siedende Lösung von Pyrogallussäure (1I50 normal), spült wiederum, preßt das überschüssige Wasser aus und trocknet an der Luft in der Kälte.A woven fabric of plain weave, whose warp and weft consist of acetate rayon, is 3 hours added to an aqueous solution that contains io ° / 0 calcium chloride; you rinse and squeeze, then immerse for 10 minutes in a boiling solution of pyrogallic acid ( 1 l 50 normal), rinse again, squeeze out the excess water and dry in the cold in the air.
Das Gewebe ist leicht matt und hat das Ansehen von wilder (Tussah) Seide angenommen.The fabric is slightly matt and has taken on the appearance of wild (tussah) silk.
Gegenüber der bisher bekannten Verwendung von konzentrierten Salz- oder Essigsäurelösungen zum Mattieren von Acetatseide hat also das vorliegende Verfahren den Vorteil, daß bei ihm die gewünschten Matt- und Wolleffekte von vorzüglichem Aussehen ohne die geringste Faserschädigung erreicht werden.Compared to the previously known use of concentrated hydrochloric or acetic acid solutions for matting acetate silk, the present process has the advantage that with him the desired matt and wool effects of excellent appearance without the slightest Fiber damage can be achieved.
