Description

  

  Färbepräparat.    Es wurde gefunden, dass man mit wasser  löslichen Chromverbindungen von     chromier-          bare    Gruppen enthaltenden     Azofarbstoffen,     welche pro     chromierbare    Gruppe     ein    Atom  Chrom komplex gebunden enthalten, vorteil  haft in Gegenwart von     niedrigmolekularen          Aminosäuren    aus stark saurem, insbesondere  schwefelsaurem Bade färbt.  



  Gegenstand des vorliegenden Patentes ist  nun ein beständiges Färbepräparat, enthal  tend eine wasserlösliche Chromverbindung  eines     chromierbare    Gruppen enthaltenden     Azo-          farbstoffes,    die pro     chromierbare    Gruppe 1  Atom Chrom komplex     gebunden    aufweist. Das  neue Färbepräparat ist gekennzeichnet durch  den Gehalt einer     niedrigmolekularen    Amino  säure.  



  Unter den beim vorliegenden Präparat in  Betracht kommenden wasserlöslichen Chrom  verbindungen     chromierbarer        Azofarbstoffe,     die pro     chromierbare        Gruppe    ein Atom Chrom  komplex gebunden enthalten, können allge  mein diejenigen erwähnt werden, die aus vie  len Patenten ihrer Zusammensetzung nach  und aus sonstigen Veröffentlichungen als        Neolanfarbstoffe     bekannt sind; siehe z. B.  die deutschen Patentschriften     Nrn.    416379,  338086, 411384, 407003, 374041, 441533,  448141, 473827, 480225, 550930, 464695,  832648 und 848979.  



  Als     niedrigmolekulare        Aminosäuren    kom  men vorzugsweise die     niedrigmolekularen          Aminocarbonsäuren    der     aliphatischen    Reihe,  vor allem     Glykokoll        (Aminoessigsäure),    in Be-         tracht.        Glykokoll    kann man als solches oder  gegebenenfalls in Form eines seiner Salze,  z.

   B. in Form von     Glykokollsulfat,    verwenden,  Die.     Verwendung    von     Glykokollsulfat    ermög  licht, dass gleichzeitig mit dem     Glykokoll    min  destens ein Teil der für den Färbevorgang,  nötigen Schwefelsäure im zur Vorbereitung  der Färbebäder verwendbaren Präparat vor  handen ist. Selbstverständlich kann man auch  Mischungen von     Glykokoll    und     Glykokollsulfat     verwenden. Die verwendete Menge     Glykokoll,          kann    zwischen weiten Grenzen variiert wer  den.

   Zweckmässig sorgt man dafür, dass das  Färbepräparat so viel     Glykokoll    enthält, dass  die daraus hergestellten Färbebäder etwa 1 bis  5 Gramm     Glykokoll    pro Liter enthalten.  



  Die neuen Präparate können beispielsweise  durch Vermischen der einzelnen Komponen  ten, d. h. der     Farbstoffchromverbindungen     mit den     Aminosäuren    bzw. deren     Salzen,    her  gestellt werden. Gegebenenfalls kann man auch ;  die betreffenden Stoffe zu     teigförmigen    Färbe  präparaten verarbeiten, welche dann für die  Vorbereitung der Färbebäder verwendet wer  den     können.       Mit den erfindungsgemässen Präparaten  werden unter Schonung des Färbegutes - was  besonders im Falle von Wolle wichtig ist   sehr gleichmässige; voll entwickelte Färbungen  erhalten.  



  In den nachfolgenden Beispielen bedeuten  die Teile, wo nichts anderes vermerkt ist,  Gewichtsteile, die Prozente Gewichtsprozente,           und    die Temperaturen sind in     Celsiusgraden     angegeben.  



       Beispiel   <I>1: -</I>  0,5 Teile der blaufärbenden     Ohromverbin-          dang    des     Monoazofarbstoffes        (1.1-Komplex)     der Formel  
EMI0002.0008     
    werden mit 2 Teilen     calciniertem    Natrium  sulfat und 3 Teilen     Glykokoll    vermischt. .  



  Das so hergestellte Präparat kann folgen  dermassen verwendet werden: Man bestellt  ein Färbebad mit 1000 Teilen Wasser, 2 Teilen       95o/oiger    Schwefelsäure und dem erhaltenen  Färbepräparat. Man geht in das so erhaltene  Färbebad mit 25 Teilen eines gut genetzten  Wollgewebes ein, treibt in 30     Minuten        zum     Kochen und hält 2 Stunden bei Kochtempera  tur. Nach gründlichem     Spülen    mit kaltem  Wasser trocknet man das gefärbte Gewebe.

    Man erhält so eine blaue Färbung, die- sich  in bezug auf Nuance     praktisch    nicht unter  scheidet von einer Färbung, die unter den  gleichen Bedingungen, aber ohne     Glykokoll    er  halten     wurde.    Die     Allialilöslichkeit        (Harris          und        Smith,        Bur.    Stand. J. Res.<B>15,</B> 63 [1935] )  der in Gegenwart von     Glykokoll    gefärbten  Wolle ist wesentlich geringer als diejenige  der in Abwesenheit von     Glykokoll    gefärbten  Wolle.  



  <I>Beispiel 2:</I>  0;5 Teile der blaufärbenden Chromverbin  dung des     Monoazofarbstoffes        (1.-        1-Komplex)       der Formel  
EMI0002.0028     
    werden mit 5 Teilen     Glykokollsulfat    vermischt.  Das erhaltene Präparat kann folgendermassen  verwendet werden: es wird in 1000 Teilen  Wasser zugegeben und im so erhaltenen  Färbebad     wird    Wolle gefärbt. Nuance und       Alkalilöslichkeit    der gefärbten Wolle sind  gleich wie im Beispiel 1.



  Dye preparation. It has been found that with water-soluble chromium compounds of chromable groups-containing azo dyes which contain one atom of chromium in complex bound form per chromable group, dyeing is advantageous in the presence of low molecular weight amino acids from strongly acidic, in particular sulfuric acid, bath.



  The subject of the present patent is now a stable dye preparation containing tend a water-soluble chromium compound of an azo dye containing chromable groups, which has 1 atom of chromium complexed per chromable group. The new dye preparation is characterized by the content of a low molecular weight amino acid.



  Among the water-soluble chromium compounds of chromable azo dyes which are suitable for the present preparation and which contain one atom of chromium complexed per chromable group, those that are known from many patents of their composition and from other publications as neolan dyes can generally be mentioned; see e.g. For example, German Patent Nos. 416379, 338086, 411384, 407003, 374041, 441533, 448141, 473827, 480225, 550930, 464695, 832648 and 848979.



  The low molecular weight aminocarboxylic acids of the aliphatic series, especially glycocoll (aminoacetic acid), are preferably considered as low molecular weight amino acids. Glycocolla can be used as such or optionally in the form of one of its salts, e.g.

   B. in the form of glycocollate, use The. The use of glycocollate enables at least part of the sulfuric acid required for the dyeing process to be present in the preparation that can be used to prepare the dye baths at the same time as the glycocollate. Mixtures of glycocolla and glycocollate sulfate can of course also be used. The amount of glycocoll used can be varied between wide limits.

   It is expedient to ensure that the dye preparation contains enough glycocolla that the dye baths made from it contain about 1 to 5 grams of glycocolla per liter.



  The new preparations can th for example by mixing the individual components, d. H. the dye chromium compounds with the amino acids or their salts are made forth. If necessary, you can also; process the substances in question into dough-like dye preparations, which can then be used to prepare the dye baths. With the preparations according to the invention, the material to be dyed is protected - which is particularly important in the case of wool - very even; fully developed colorations obtained.



  In the examples below, the parts are parts by weight, unless otherwise noted, the percentages are percentages by weight, and the temperatures are given in degrees Celsius.



       Example <I> 1: - </I> 0.5 part of the blue-coloring ear compounds of the monoazo dye (1.1 complex) of the formula
EMI0002.0008
    are mixed with 2 parts of calcined sodium sulfate and 3 parts of glycocolla. .



  The preparation produced in this way can be used as follows: A dye bath is ordered with 1000 parts of water, 2 parts of 95% sulfuric acid and the resulting dye preparation. One goes into the dyebath obtained in this way with 25 parts of a well-meshed woolen fabric, boils in 30 minutes and holds for 2 hours at the boiling temperature. The dyed fabric is dried after thorough rinsing with cold water.

    This gives a blue coloration which, in terms of shade, is practically indistinguishable from a coloration that was obtained under the same conditions but without glycocolla. The allialil solubility (Harris and Smith, Bur. Stand. J. Res. 15, 63 [1935]) of the wool dyed in the presence of glycocolla is significantly lower than that of the wool dyed in the absence of glycocolla.



  <I> Example 2: </I> 0; 5 parts of the blue-coloring chromium compound of the monoazo dye (1.-1 complex) of the formula
EMI0002.0028
    are mixed with 5 parts of glycocollate. The preparation obtained can be used as follows: 1000 parts of water are added and wool is dyed in the dyebath obtained in this way. The shade and alkali solubility of the dyed wool are the same as in Example 1.
