Description

Verfahren zum Färben von Acetatkunstseide In den folgenden Beispielen sind die Teile Gewichtsteile.Methods of dyeing acetate rayon in the following examples the parts are parts by weight.

Beispiel i 4-Teile Bz-i-äthoxybenzanthron (8°/oige Paste) werden innig mit 5o Teilen kalten Wassers gemischt. Dann werden 3ooo Teile kaltes Wasser hinzugefügt. roo Teile Acetatkunstseide werden in einer warmen, sehr verdünnten ammoniakalischen Seifenlösung gewaschen, in kaltem Wasser nachgewaschen und in das obenerwähnte kalte Färbebad eingegeben. Das Färbebad wird langsam auf 8o° C erhitzt und dann 3/4 Stunden lang bei 8o° C gehalten. Das Färbegut wird dabei ständig in dem Bade umgewendet. Dann wird das Färbegut aus dem Bade entfernt, in kaltem Wasser gewaschen und getrocknet. Es entsteht so eine grünstichiggelbe Färbung, «-elche sehr gute Echtheit gegenüber der Ein-Es wurde gefunden, daB Acetatkunstseide in klaren, grünstichiggelben Tönen gefärbt werden kann, die eine ausgezeichnete Licht-und Waschechtheit besitzen und in dieser Hinsicht den bekannten, in gleichen oder ähnlichen Tönen färbenden Acetatkunstseidefarbstoffen überlegen sind, wenn man Bz- i-alkoxybenzanthrone, die im Alkylrest a bis 5 Kohlenstoffatomeenthalten, und zw ar Bz-i-äthoxy, Bz-i-ß-chloräthoxy-, Bz-i-n-butoxy- und Bzi-n-amyloxybenzanthron, in unverküptem Zustande zum Färben verwendet.Example i 4 parts of Bz-i-ethoxybenzanthrone (8% paste) become intimate mixed with 50 parts of cold water. Then 3,000 parts of cold water are added. Roo parts of acetate rayon are in a warm, very dilute ammoniacal Soap solution washed, rewashed in cold water and put in the cold water mentioned above Dye bath entered. The dyebath is slowly heated to 80 ° C and then 3/4 hours kept at 80 ° C for a long time. The material to be dyed is constantly turned over in the bath. The dyed material is then removed from the bath, washed in cold water and dried. The result is a greenish yellow coloration, "which is very fast against it It has been found that acetate rayon has clear, greenish-yellow tones can be dyed, which have excellent light and wash fastness and in this respect the known acetate rayon dyes which dye in the same or similar shades are superior if one uses Bz-i-alkoxybenzanthrones which contain up to 5 carbon atoms in the alkyl radical and between Bz-i-ethoxy, Bz-i-ß-chloroethoxy, Bz-i-n-butoxy and Bzi-n-amyloxybenzanthrone, Used for dyeing in the uncooled state.

Diese Farbstoffe ziehen sehr gut auf Acetatkunstseide und die damit hergestellten Färbungen sind nicht phototrop.These dyes pull very well on acetate rayon and those with it The colorations produced are not phototropic.

Diese neuen Farbstoffe können durch Umsetzen von Bz-i-oxybenzanthron mit dem entsprechenden Alkylester einer anorganischen Säure oder einer Arylsttlfonsäure hergestellt werden, beispielsweise Diäthylsulfat, p=Toluols.ulfonsäureäthylester, Äthylbromid. wirkurig von Licht, Waschen, Säuren, Alkalien, Abgasen und heißem Pressen aufweist.These new dyes can be obtained by reacting Bz-i-oxybenzanthrone with the corresponding alkyl ester of an inorganic acid or an aryl sulfonic acid be prepared, for example diethyl sulfate, p = toluene sulfonic acid ethyl ester, Ethyl bromide. effective from light, washing, acids, alkalis, exhaust gases and hot pressing.

Bz-i-äthoxybenzänthrön kann in der im Beispiel 3 der britischen Patentschrift 333 5U beschriebenen Weise hergestellt werden.Bz-i-ethoxybenzänthrön can be found in example 3 of the British patent 333 5U described in the manner described.

Beispiel 1ö Teile Bz-i-äthoxybenzanthron (g°@ö > Paste) werden mit 25 Teilen Wasser verrührt, und die Aufschwemmung wird mit 6o Teilen Senegalgummiverdickung (i : i) und 5 Teilen Glycerin gemischt. Mit diesem Gemisch wird Acetatkunstseide bedruckt, getrocknet, bei zoo° C '/2 Stunde lang gedämpft, dann in Wasser gewaschen, um das Verdickungsmittel zu entfernen, und getrocknet. .:Es entsteht so ein grünstichiggelber Druck. @'s.`= Beispiel 3 `Es kann auch mit folgenden Bz-i-alkoxy-.enzanthronen in der in den Beispielen i und a angegebenen Weise gefärbt und gedr@uckt werden, und es entstehen Färbungen mit den gleichen Echtheitseigenschaften: Die dabei erhaltenen Farbtöne sowie die Herstellung und Eigenschaften dieser Farbstoffe sind aus der folgenden Zusammenstellung zu entnehmen Example 10 parts of Bz-i-ethoxybenzanthrone (g ° @ ö> paste) are stirred with 25 parts of water, and the suspension is mixed with 60 parts of Senegal gum thickening (i: i) and 5 parts of glycerine. This mixture is printed on acetate rayon, dried, steamed at zoo ° C 1/2 hour, then washed in water to remove the thickener, and dried. .: The result is a greenish yellow print. @ 's.` = Example 3 `The following Bz-i-alkoxy-.enzanthrones can also be dyed and printed in the manner indicated in Examples i and a, and colorations with the same fastness properties result: The The color shades obtained and the preparation and properties of these dyes can be found in the following table
