Verfahren zur Erzeugung von Azofarbstoffen a, nf beschwerter Seide.
Durch das Stammpatent Nr. 107 843 ist ein Verfahren zur Erzeugung von Azofarbstoffen auf Seide geschützt, das darin besteht. dass man die Seidenfaser mit einer Lösung einer Azokomponente mit substantivem Charakter grundiert und mit einer Diazolösung entwickelt.
Dieses Verfahren liefert aber auf besehwerter Seide keine einwandfreien Ergebnisse. da bei der Behandlung der Seide im ätzalkalischen Grundierungsbade die Zinnbeschwerung teilweise von der Seidenfaser herunter gelöst wird und mit der gelösten Farbstoffkomponente des Grundierungsbades Ausfällungen gibt. Diese verschmieren das Bad und bilden auf der Seidenfaser Ausscheidungen, die das weitere Aufziehen der Farbstoffkomponente verhindern, so dass die entwickelten Färbungen nicht nur sehr schwach und ungleichmässig sind. sondern auch der Seide dadurch deren charakteristischer Glanz und Griff genommen wird.
Es wurde nun überraschender Weise gefunden, dass sich dieser Übelstand vermeiden lässt. wenn
EMI1.1
zusetzt. Das Bad bleibt dann vollkommen klar. die Farbstoffkomponente zieht gleichmässig auf und die ausgefärbte Seide hat nichts von ihrem Glanz und Griff eingebiisst.
Beispiel.
EMI1.2
ss-Oxynaphtoesäureanilid und 15 cm3 Wasserglas 250 Bé im Liter enthält, grundiert. Dann setzt man 10 g Kochsalz (1 : 4 in Wasser gelöst) pro Liter zu, hantiert weitere 20 Minuten und entwickelt nach gründlichem Schleudern mit einer essigsauren Lösung, welche 3 g diazotiertes m-Nitro-oanisidin-chlor- hydrat im Liter enthält, säuert mit Salzsäure schwach ab, spiilt gründlich aus, seift hierauf zweimal

und kalt, aviviert mit Essig-, Ameisen-, Schwefel- oder Weinsäure und trocknet. Das verwendete ss-Oxynaphtoesäureani1id wird mit der l 2fachen Menge Natronlauge 34 Bé unter Zusatz der gleichen
Menge Türkischrotöl und der 0'5fachen Menge Leim gelöst.
Als Schutzkolloid wurde dem Grun- dierungsbade die 0'5fache Menge sogenanntes Protektol-I-Pulver doppelt, d. i. gereinigte Sulfitzellulose- ablauge in Pulverform, zugesetzt. Die so erhaltene scharlachrote Färbung zeichnet sich durch Fülle,
Glanz und Griff aus.
Der gleiche Effekt wird erzielt, wenn man anstatt des Silikates ein lösliches Phosphat oder ein
Gemisch beider verwendet.
In der oben beschriebenen Weise können auch andere Aryiide der 2'3-0xynaphtoesäure und andere Körper, die eine kupplungsfähige Methylengruppe enthalten, unter Zusatz von ätzalkalisehem Silikat oder Phosphat oder eines Gemische : beider, für die Grundierung verwandt werden, ebenso auch andere
Diazoverbindungen für die Entwicklung.

Process for the production of azo dyes a, nf weighted silk.
A process for the production of azo dyes on silk is protected by the parent patent no. 107 843, which consists in this. that the silk fiber is primed with a solution of an azo component with a substantive character and developed with a diazo solution.
However, this process does not provide perfect results on silk that is worth seeing. because when treating silk in an alkaline primer bath, the weight of the tin is partially loosened from the silk fiber and precipitates with the dissolved dye component of the primer bath. These smear the bath and form excretions on the silk fiber, which prevent the dye components from being absorbed further, so that the colorations developed are not only very weak and uneven. It also removes the characteristic shine and feel of the silk.
It has now surprisingly been found that this deficiency can be avoided. if
EMI1.1
clogs. The bathroom then remains completely clear. the dye component is absorbed evenly and the colored silk has lost none of its shine and feel.
Example.
EMI1.2
contains ss-oxynaphthoic anilide and 15 cm3 water glass 250 Bé per liter, primed. Then 10 g sodium chloride (1: 4 dissolved in water) per liter are added, handled for a further 20 minutes and, after thorough spinning, developed with an acetic acid solution containing 3 g of diazotized m-nitro-oanisidine chlorohydrate per liter, acidified weakly rinsed off with hydrochloric acid, rinsed out thoroughly, then soaped twice
EMI1.3
and cold, enriched with acetic, formic, sulfuric or tartaric acid and dries. The ß-Oxynaphtoesäureani1id used is with 12 times the amount of caustic soda 34 Be with the addition of the same
Amount of Turkish red oil and 0.5 times the amount of glue dissolved.
As a protective colloid, 0.5 times the amount of so-called Protektol-I powder was added twice to the primer bath, i.e. i. Purified sulphite cellulose waste liquor in powder form added. The scarlet color obtained in this way is characterized by abundance,
Shine and grip off.
The same effect is achieved if instead of the silicate a soluble phosphate or a
Mixture of both used.
In the manner described above, other aryls of 2'3-oxynaphthoic acid and other substances which contain a methylene group capable of coupling, with the addition of caustic silicate or phosphate or a mixture of both, can be used for the primer, as can others
Diazo compounds for development.
