Zerstörung von Azofarben auf Textilstoffen.Destruction of azo inks on textile fabrics.
Patentirt im Deutschen Reiche vom 13. März 1902 ab.Patented in the German Empire on March 13, 1902.
Vorliegende Erfindung bezieht sich auf einThe present invention relates to a
Verfahren zur Erzeugung von Reserve- und Aetz-Effekten in der Zeugdruckerei bezw. zur gänzlichen Zerstörung von Azofarben auf Textilstoffen. Process for the generation of reserve and Aetz effects in the stuff printing shop respectively. to the Complete destruction of azo inks on textiles.
Die Verfahren, deren man sich zu diesen Zwecken bedient hat, beruhen in den meisten Fällen auf der Verwendung eines Reductionsmittels. Zur Erzeugung von Reserve-Effekten wird das Reductionsmittel, mit einer passenden Verdickung gemischt, vor dem Färben auf die präparirte Faser aufgedruckt, während zur Erzeugung eines Aetz-Effektes der Aufdruck des Reductionsmittels nach dem Färben geschieht.The procedures which have been used for these purposes are based on most of them Cases on the use of a reducing agent. To create reserve effects the reducing agent, mixed with a suitable thickener, is applied to the before dyeing Prepared fiber is printed, while the printing of the to produce an etching effect Reducing agent happens after dyeing.
ig Zur gänzlichen Zerstörung der Farben von Textilstoffen, welche mit Azofarben gefärbt worden sind, wird der gefärbte Stoff in einer Lösung des Reductionsmittels behandelt.ig For the complete destruction of the colors of textiles which have been dyed with azo colors the dyed fabric is treated in a solution of the reducing agent.
Als Reductionsmittel kamen bisher zu diesem Zwecke zur Verwendung: Salze des Zinnoxyduls, besonders Zinnsalz, sowie Salze der hydroschwefligen Säure, der schwefligen Säure und des Schwefelwasserstoffs (Sulfide).The following reducing agents have been used for this purpose: salts of tin oxide, especially tin salt, as well as salts of hydrosulphurous acid, sulphurous acid and hydrogen sulphide (sulphides).
Durch Versuche ist gefunden worden, dafs weit bessere Resultate zu erhalten sind, wenn man sich statt der vorerwähnten Reductionsmittel, der Salze des Titanoxyduls Ti2 O3, wie z. B. des Titantrichlorids (Titanchlorürs) Ti CZ3, bedient.It has been found through experiments that far better results can be obtained if, instead of the aforementioned reducing agents, one uses the salts of titanium oxide Ti 2 O 3 , such as e.g. B. of titanium trichloride (titanium chloride) Ti CZ 3 , served.
Solche Salze lassen sich leicht durch Einwirkung gewisser Metalle, wie z. B. Zink, Zinn, Aluminium, auf die im Handel leicht erhältlichen Titanoxydsalze oder durch Elektrolyse solcher Salze erhalten (vergl. z.B.Dammer's Handbuch der anorganischen Chemie, Band II, 1, S. 588).Such salts can be easily removed by the action of certain metals, such as. B. zinc, Tin, aluminum, the titanium oxide salts readily available in the trade, or by electrolysis obtained from such salts (see e.g. Dammer's Handbuch der Inorganic Chemistry, Volume II, 1, P. 588).
Diese Titanoxydulsalze zeichnen sich durch ihre aufserordentlich starke Reductionskraft aus und können aus diesem Grunde die gegenwärtig im Gebrauch befindlichen, obengenannten Reductionsmittel mit grofsem Vortheil ersetzen.These titanium oxide sulfide salts are characterized by their extraordinarily strong reducing power and for this reason we may use the above-mentioned ones currently in use Replace reducing agents with great advantage.
Die praktische Durchführung der Erfindung wird durch nachfolgende Beispiele erläutert:The practical implementation of the invention is illustrated by the following examples:
Beispiel 1. Erzeugung einer weifsen Reserve unter Paranitranilin-Roth auf Baumwoll-Stückwaare. Example 1. Creation of a white reserve under Paranitranilin-Roth on cotton pieces.
Nachdem die Stücke in der üblichen Weise mit Beta-Naphtol präparirt worden sind, werden sie mit einer Schutzbeize oder Reserve bedruckt, welche aus 100 g Dextrinverdickung und 10 g Titantrichlorid besteht. Nach dem Trocknen bei mä'fsiger Temperatur wird der bedruckte Stoff durch eine Lösung von diazotirtem Paranitranilin und essigsaurem Natron hindurchgezogen. Nachdem die Stücke so lange mit der Diazolösung in Berührung gewesen sind, bis sich die Farbe an den ungeschützten Theilen entwickelt hat, werden sie gewaschen und getrocknet.After the pieces have been prepared with beta-naphthol in the usual manner, they become they are printed with a protective stain or reserve, which consists of 100 g of dextrin thickening and 10 grams of titanium trichloride. After drying at a moderate temperature, the printed fabric by a solution of diazotized paranitraniline and acetic acid soda pulled through. After the pieces have been in contact with the diazo solution for so long until the color has developed on the unprotected parts, they will washed and dried.
Beispiel 2. Herstellung eines weifsen Aetz-Effektes auf Baumwoll-Stückwaare, welche mit Benzopurpin 4 B gefärbt worden ist.Example 2. Preparation of a whites etching effect on cotton Stückwaare which has been dyed with Benzopurpin 4 B.
Das gefärbte Gewebe wird mit einem Aetzmittel bedruckt, welches wie folgt hergestellt wird: 100 g einer Verdickung von- geeigneter Consistenz, zweckmäfsig aus stark gebrannterThe dyed fabric is printed with an etching agent, which is produced as follows becomes: 100 g of a thickening of a suitable consistency, expediently from heavily burned
Stärke hergestellt, werden mit ι bis 5 g Titantrichlprid und '1 bis'10. g Rhodanammon gemischt. Nach dom Druck wird· das: Gewebe getrocknet, zwei Minuten "lang irr einem geeigneten Apparate gedämpft und dann gewaschen. Starch made with ι to 5 g of titanium trichlpride and '1 to'10. g rhodanammon mixed. After the pressure is applied, the fabric is dried, steamed for two minutes in a suitable apparatus and then washed.
Beispiel 3. Vollständige Vernichtung von Azofarbstoffen auf Geweben.Example 3. Complete destruction of azo dyes on fabrics.
Es wird eine warme oder heifse Lösung von Titantrichlorid hergestellt, in welche das gefärbte Gewebe eingebracht und etwa 15 Minuten lang in Bewegung gehalten wird. Die Stärke der Lösung wird sich naturgemäfs nach der Tiefe der Färbung und nach der Natur des Farbstoffs richten. In der Regel wird aber das Gewicht des zu verwendenden Titantricblorids nicht mehr als 5 pCt. des Gewichtes des zu behandelnden Gewebes ausmachen.A warm or hot solution of titanium trichloride is made into which the dyed tissue is introduced and kept in motion for about 15 minutes. the The strength of the solution will naturally vary according to the depth of the color and nature of the dye. As a rule, however, the weight of the titanium tricloride to be used not more than 5 pCt. the weight of the tissue to be treated.
An Stelle des in den Beispielen angeführten Titantrichlorids können entsprechende Mengen Titanoxydul-Sulfat, -Oxalat, -Rhodanür oder andere Titanoxydul-Salze zur Verwendung gelangen. Corresponding amounts can be used in place of the titanium trichloride listed in the examples Titanium oxide sulfate, oxalate, rhodanur or other titanium oxide salts are used.
