Description

  

      Verfahren    zum     Imprägnieren        natürlicher    und künstlicher Leder    Beim Imprägnieren,     z.B.    Färben oder Bedrucken, von  Leder verwendet man häufig wässrige     Farbstoffzuberei-          tungen,    die oberflächenaktive Mittel, organische Lö  sungsmittel oder andere     Hilfsstoffe    enthalten. Es besteht  der Wunsch, diese     Farbstoffzubereitungen    durch Bürsten,  Spritzen oder Giessen aufzutragen, doch dringt der       Farbstoff    dabei nicht genügend tief in das Leder ein und  man erhält ungleichmässige und nicht genügend echte  Färbungen.  



  Es wurde gefunden, dass diese Nachteile vermieden  werden, wenn man Leder mit einer wässrigen Zuberei  tung, vorzugsweise     Farbstoffzubereitung,    imprägniert, die  ein wasserlösliches Salz einer geblasenen Fettsäure ent  hält. Mit diesem Verfahren lassen sich alle natürlichen  Leder imprägnieren,     z.B.    Narbenleder,     geschliffenes    oder  gespaltenes Leder oder     Velourleder    und die Fleischseite  von gegerbten Fellen, sowie künstliche Leder,     z.B.    solche  aus Polyestermaterial, wie      Corfam     (eingetragene  Schutzmarke), vgl. deutsche Auslegeschrift Nr.<B>1109</B> 640.  Es ist nicht an die Verwendung bestimmter Farbstoffe  oder Chemikalien gebunden.

   Vielmehr lassen sich alle  bekannten, in der     Lederbehandlung    üblichen     Farbstoffe,     Chemikalien, Weichmacher usw. verwenden. Als Farb  stoffe kommen insbesondere Dis- oder     Trisazofarbstoffe     oder     Metallkomplexfarbstoffe    in Betracht, wobei     verhält-          nismässig    gut wasserlösliche Vertreter dieser Gruppen,       z.B.    solche, von denen mindestens 15 g in einem Liter  Wasser löslich sind, bevorzugt sind.  



  Geblasene Fettsäuren sind bekanntlich bei erhöhter  Temperatur mit     Luftsauerstoff    behandelte natürliche,  ungesättigte Fettsäuren, das sind     höhermolekulare        ali-          phatische        Carbonsäuren    mit mindestens einer     olefini-          schen    Doppelbindung, die etwa 12 bis 28 und insbesonde  re 14 bis 18     Kohlenstoffatome    enthalten. Mit besonderem  Vorteil werden Salze aus geblasenen     Ricinusölfettsäuren     und Ammoniak oder organischen Aminen eingesetzt.

    Diese     Salze    wendet man vorzugsweise in Mengen zwi  schen ungefähr 10 und 800 g und insbesondere zwischen  40 und 400 g je 1 Liter Zubereitung an.  



  Die verwendeten Zubereitungen können zusätzliche       Hilfsmittel    enthalten. Mit besonders gutem Erfolg ver  wendet man ein oder mehrere organische Lösungsmittel    und/oder kleine Mengen     anionaktiver    oder nicht     ionoge-          ner    Netz- und/oder     Dispergiermittel,    sowie Fettstoffe,  Gerbstoffe, wie natürliche und synthetische Fettstoffe  oder Gerbstoffe, ferner     Kunstharzdispersionen,        Verdik-          kungsmittel.    Als organische Lösungsmittel kommen vor  allem flüssige, gesättigte     Kohlenwasserstoffe,

          z.B.    flüssige       Erdölfraktionen,        in    Betracht. Ferner sind Glykole geeig  net,     z.B.        Äthylenglykol    oder     Hexylenglykol    oder deren  Äther,     z.B.    der     Äthylenglykolmonomethyläther    oder der       Äthylenglykolmonoäthyläther,    andere     Glykolderivate     oder drei- und mehrwertige     Alkohole,

          z.B.        Sorbit.    Als  zusätzliche Netz- oder     Dispergiermittel    dienen mit beson  derem     Vorteil        sulfoniertes        Ricinusöl    oder     polyoxäthylier-          te        Phenole    und     Alkylphenole    oder     höhermolekulare          Alkohole.    20 g/1 übersteigende Mengen flüssiger Erdöl  fraktionen ergeben im allgemeinen keine zusätzlichen  Vorteile. Von Glykolen kann man     z.B.    10 bis 200 g und  vorzugsweise 30 bis 150 g je Liter Zubereitung verwen  den.

   Ferner lassen sich     z.B.        Kunstharzbindemittel,    Auf  hellungsmittel, Verdickungsmittel, Fette oder Gerbstoffe       mitverwenden.    Der     pH-Wert    dieser Flotten oder Pasten  beträgt im allgemeinen 6 bis 12 und vorzugsweise 7 bis  11. Ihre Temperatur kann normal oder erhöht sein. Das  Auftragen kann     z.B.    durch Bürsten (Plüschen), Rollen,  Spritzen oder Giessen,     z.B.    mit Hilfe einer üblicherweise  für das     Imprägnieren    oder Beschichten von Leder und  Kunststoffolien verwendeten Giessmaschine, erfolgen.

    Das imprägnierte Leder wird in     bekannter    Weise bei  Raumtemperatur oder bei erhöhter Temperatur getrock  net und fertiggestellt.  



  Die in den Beispielen genannten Teile sind Gewichts  teile und die Prozente Gewichtsprozente. Die Temperatu  ren sind in Celsiusgraden angegeben.  



  <I>Beispiel 1</I>  Man stellt ein Gemisch aus 62,5 Teilen geblasener       Ricinusölfettsäure    mit der     Säurezahl    100, 12,5 Teilen       Morpholin,    5 Teilen des Hilfsmittels aus dem Beispiel 25  der französischen Patentschrift Nr.<B>1312787,</B> 60 Teilen       Hexylenglykol,    40 Teilen     Äthylenglykol,    10 Teilen      Pe-          trol ,    einer geruchlosen     Erdölfraktion,    5 Teilen     25%iger     wässriger     Ammoniaklösung    und 10 Teilen einer 70%igen      wässrigen     Sorbitlösung    her.

   Von dieser Mischung, die  den     pH-Wert    8,8 hat, werden<B>150</B> Teile mit 38 Teilen des  Farbstoffs des Beispiels 1 der französischen Patentschrift  Nr.<B>1073</B> 728 und 812 Teilen Wasser vermischt.  



  Mit dieser Flotte vom     pH-Wert    9,4 wird gegerbtes  und getrocknetes, vollnarbiges Leder imprägniert. Hier  auf wird 24 Stunden bei Raumtemperatur     gelagert,     getrocknet und wie üblich zugerichtet,     z.B.    mit Hilfe  einer Bügel- oder     Glanzstossmaschine.     



  Der Farbstoff ist tief in das Leder eingedrungen. Die  erhaltene Färbung ist sehr egal, kratz- und scheuerfest,  lichtecht, reibecht, schleifecht und     formaldehyd-    und  säurebeständig. Das gefärbte Leder kann ohne weiteres  mit Pigmentdispersionen behandelt werden.

      <I>Beispiel 2</I>  Man stellt ein Gemisch aus 62,5 Teilen geblasener       Ricinusölfettsäure    mit der Säurezahl 100, 12,5 Teilen       Morpholin,    5 Teilen des     Hilfsmittels    aus dem Beispiel 25  der französischen Patentschrift Nr.<B>1312787,</B> 60 Teilen       Hexylenglykol,    40 Teilen     Äthylenglykol,    10 Teilen      < cPe-          trol ,    einer geruchlosen Erdölfraktion, 5 Teilen     25a/oiger     wässriger     Ammoniaklösung    und 10 Teilen einer     70%igen     wässrigen     Sorbitlösung.     



  Von dieser Mischung, die den     pH-Wert    8,8 hat,  werden 125 Teile mit 20 Teilen des Farbstoffes des  Beispiels 1 der französischen Patentschrift Nr.<B>1073</B> 728  und 855 Teilen Wasser vermischt. Mit dieser Flotte vom       pH-Wert    9,2, wird     im    Formkörper, wie er im Beispiel 1  der deutschen Auslegeschrift Nr. 1 109 640 beschrieben  wird, imprägniert.  



  Der Formkörper wird hierauf bei Raumtemperatur  während 5 Stunden gelagert, getrocknet und wie bei  Leder üblichen Massnahmen zugerichtet. Eine Trock  nung bei 95  während mehreren Minuten verbessert die       Fixierung    des Farbstoffes.  



  Der Farbstoff ist tief und gleichmässig in den Form  körper eingedrungen; er ist vollständig durchfärbt. Man  erhält eine egale und satte Braunfärbung. Die Wasser  dampfdurchlässigkeit, die Flexibilität, die Formbestän-         digkeit    und     Zurichtbarkeit    mit Pigmentdispersionen des       Formkörpers    wird nicht beeinträchtigt.



      Process for the impregnation of natural and artificial leathers When impregnating, e.g. Dyeing or printing, leather is often used in aqueous dye preparations containing surface-active agents, organic solvents or other auxiliaries. There is a desire to apply these dyestuff preparations by brushing, spraying or pouring, but the dyestuff does not penetrate deep enough into the leather and uneven and not sufficiently true dyeings are obtained.



  It has been found that these disadvantages are avoided if leather is impregnated with an aqueous preparation, preferably a dye preparation, which contains a water-soluble salt of a blown fatty acid. With this method all natural leathers can be impregnated, e.g. Grain leather, sanded or split leather or suede and the flesh side of tanned hides, as well as artificial leather, e.g. those made of polyester material, such as Corfam (registered trademark), cf. German Auslegeschrift no. <B> 1109 </B> 640. It is not tied to the use of specific dyes or chemicals.

   Rather, all known dyes, chemicals, plasticizers, etc. that are common in leather treatment can be used. Particularly suitable dyes are disazo or trisazo dyes or metal complex dyes, with representatives of these groups being relatively well soluble in water, e.g. those of which at least 15 g are soluble in one liter of water are preferred.



  As is known, blown fatty acids are natural, unsaturated fatty acids treated with atmospheric oxygen at elevated temperature, that is, higher molecular weight aliphatic carboxylic acids with at least one olefinic double bond which contain about 12 to 28 and in particular 14 to 18 carbon atoms. Salts of blown castor oil fatty acids and ammonia or organic amines are used with particular advantage.

    These salts are preferably used in amounts between approximately 10 and 800 g and in particular between 40 and 400 g per 1 liter of preparation.



  The preparations used can contain additional auxiliaries. One or more organic solvents and / or small amounts of anionic or nonionic wetting agents and / or dispersants, as well as fatty substances, tanning agents such as natural and synthetic fatty substances or tanning agents, and also synthetic resin dispersions, thickeners are used with particularly good success. The main organic solvents are liquid, saturated hydrocarbons,

          e.g. liquid petroleum fractions. Glycols are also suitable, e.g. Ethylene glycol or hexylene glycol or their ethers, e.g. ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, other glycol derivatives or tri- and polyhydric alcohols,

          e.g. Sorbitol. Sulfonated castor oil or polyoxyethylated phenols and alkylphenols or higher molecular weight alcohols serve with particular advantage as additional wetting or dispersing agents. Quantities of liquid petroleum fractions exceeding 20 g / 1 generally do not provide any additional advantages. Glycols can e.g. 10 to 200 g and preferably 30 to 150 g per liter of preparation use the.

   Furthermore, e.g. Use synthetic resin binders, brighteners, thickeners, fats or tannins. The pH of these liquors or pastes is generally 6 to 12 and preferably 7 to 11. Their temperature can be normal or elevated. The application can e.g. by brushing (plush), rolling, spraying or pouring, e.g. with the aid of a casting machine usually used for the impregnation or coating of leather and plastic films.

    The impregnated leather is net getrock and finished in a known manner at room temperature or at an elevated temperature.



  The parts mentioned in the examples are parts by weight and the percentages are percentages by weight. The temperatures are given in degrees Celsius.



  <I> Example 1 </I> A mixture of 62.5 parts of blown castor oil fatty acid with an acid number of 100, 12.5 parts of morpholine and 5 parts of the auxiliary from example 25 of French patent specification no. 1312787, <is prepared / B> 60 parts of hexylene glycol, 40 parts of ethylene glycol, 10 parts of petrol, an odorless petroleum fraction, 5 parts of 25% strength aqueous ammonia solution and 10 parts of a 70% strength aqueous sorbitol solution.

   From this mixture, which has a pH value of 8.8, <B> 150 </B> parts with 38 parts of the dye of Example 1 of French Patent Specification No. 1073 </B> are 728 and 812 parts of water mixed.



  This liquor with a pH of 9.4 is used to impregnate tanned and dried, full-grain leather. Here it is stored for 24 hours at room temperature, dried and trimmed as usual, e.g. with the help of an ironing or polishing machine.



  The dye has penetrated deep into the leather. The coloring obtained is very unimportant, scratch and scuff resistant, lightfast, rubfast, abrasive resistant and formaldehyde and acid resistant. The dyed leather can easily be treated with pigment dispersions.

      <I> Example 2 </I> A mixture of 62.5 parts of blown castor oil fatty acid with an acid number of 100, 12.5 parts of morpholine and 5 parts of the auxiliary from example 25 of French patent specification no. 1312787, <is prepared / B> 60 parts of hexylene glycol, 40 parts of ethylene glycol, 10 parts of <cPetrol, an odorless petroleum fraction, 5 parts of 25% aqueous ammonia solution and 10 parts of a 70% strength aqueous sorbitol solution.



  From this mixture, which has a pH of 8.8, 125 parts are mixed with 20 parts of the dye of Example 1 of French Patent Specification No. 1073 728 and 855 parts of water. This liquor with a pH of 9.2 is used to impregnate the molding as described in Example 1 of German Auslegeschrift No. 1 109 640.



  The shaped body is then stored at room temperature for 5 hours, dried and finished as usual with leather. Drying at 95 for several minutes improves the fixation of the dye.



  The dye has penetrated deeply and evenly into the mold; it is completely colored. A level and deep brown color is obtained. The water vapor permeability, flexibility, dimensional stability and adjustability with pigment dispersions of the molding are not impaired.
