Definitions

  • oxyethylated amines are used, inter alia, as leather dyeing aids. Without any special measures, for example intensive milling in a short liquor, the dye penetrates the leather only a little from the grain side in this process. Later scratches on the leather dyed in this way are therefore very annoying.
  • combinations of oxyethylated amines and oxyethylated alcohols can also be used as auxiliaries for dyeing nitrogenous fibrous materials by the padding process.
  • An example of this is not given.
  • the dyebath must contain 4 to 30% carboxylic acid, and the dyed goods must be stored in a moist state for 10 minutes to 24 hours after impregnation. The process therefore requires several work steps and is therefore labor-intensive and time-consuming.
  • the invention was based on the object of developing a simple dyeing process and a dyeing aid for grain leather that solves all of the problems mentioned at the same time, that is to say, with completely or predominantly cationically tanned grain leather to high levelness and good coloration and with anionically tanned or retanned leather at the same time, i.e. . d. in addition to levelness and coloring, also leads to deep shades.
  • one and the same surfactant solution is used for every leather dyeing with anionic dyes, regardless of how the leather was tanned, regardless of and also deeply penetrated dyeings from the grain side, even in rich shades.
  • different aids had to be used depending on the type of leather.
  • the surfactant mixture can be used before the dye or simultaneously with it. Simultaneous addition is preferred.
  • the dye is advantageously allowed to run for 5 to 90, preferably 15 to 30 minutes, and the surfactant mixture is then added.
  • Grain leather has the natural grain, which is known to be more difficult to color and color than the flesh side and as leather with a polished surface.
  • “Dyeing leather” here means leather dyeing in the narrower sense, that is to say with dyes that attach to the leather fiber, not the finishing of leather with body colors and the varnishing.
  • Anionic dyes are those with one or more acid residues, mostly sulfonic acid residues. According to Ullmann, Encyclopedia of Technical Chemistry, Volume 11, page 573, these include the following classes of dyes, which are described in more detail on pages 574 and 575 and in particular on the pages mentioned in Volume 4: Acidic Dyes, Native Dyes, Development and Pickling - and metal complex dyes. Thanks to their good fastness properties, they are the most common dyes in leather dyeing.
  • Cationically tanned leather is essentially leather tanned with mineral tannins.
  • Mineral tannins mainly consist of salts of trivalent chromium, as well as aluminum and tetravalent zircon.
  • An anionically tanned or retanned leather means a leather that has been tanned or retanned with vegetable or with anionic synthetic tannins and contains more than 6%, based on the dry weight of the skin, of vegetable and / or anionic synthetic tannins.
  • Vegetable tanning agents are the oldest tanning agents at all and therefore do not really need to be defined here. The most important are: extracts from the bark of various tree species (especially oak, spruce, mimosa, mangrove), but also from the heartwood (quebracho, chestnut, oak) as well as from leaves and / or petioles (sumac, gambir) or from Fruits (Algarobilla, Bablah, Divi-divi, Myrobalane, Valonea). They are described in more detail in Ullmann, volume 11, pages 585-595.
  • the anionic synthetic tanning agents consist essentially of the so-called syntans, ie condensates of phenolic and / or sulfonated aromatics with formaldehyde, it being possible for the sulfonation to be carried out before or after the condensation. They are described in Ullmann, volume 11, pages 595-600.
  • the lignin sulfonates described on page 777 are also included. They have in common that they have a more or less pronounced anionic character, which they impart to tanned or retanned leather (if the amount of tanning agent used for retanning is sufficient, i.e. more than about 6% by weight, based on the dry weight) of leather.
  • Examples of 3- to 120-, preferably 60- to 100-fold, ethoxylated aliphatic alcohols with 9 to 24, preferably 10 to 18 carbon atoms (group a) which can be used according to the invention as surfactant are: the corresponding oxyethylation products of natural tallow fatty alcohol, synthetic tallow fatty alcohol, Cg / C n oxo alcohol, C 13 / C 15 oxo alcohol.
  • the surfactant mixture consisted of 30 parts of a tallow fatty alcohol reacted with 80 mol of ethylene oxide, 40 parts of an oleylamine reacted with 12 mol of ethylene oxide and 30 parts of water. Then 4 parts of a commercial fat oil based sperm oil were added, drummed again for 60 minutes and acidified with 0.5 parts of formic acid. After the leather had been tumbled for another 20 minutes, it was removed from the fleet and finished in the customary manner.
  • the leathers were then deacidified in 100 parts of water with 2 parts of sodium sulfite and 1 part of sodium formate for 60 minutes at 40 ° C. by drumming in a barrel (final pH: 4.9).
  • the leather was then dissolved in 30 parts of water with 6 parts of mimosa extract, 6 parts of sumac extract, 6 parts of a synthetic tanning agent based on phenolsulfonic acid, 1 part of sodium formate, 0.3 part of the tetrasodium salt of ethylenediaminetetraacetic acid and 3 parts of a commercial fatliquor on sperm. oiled for 90 minutes at 40 ° C.
  • the retanned leather was then washed for 10 minutes with 300 parts of 50 ° C warm water.
  • the leather in 100 parts of water at 50 ° C with 2 parts of the dye consisting of the 1: 1 copper complex of colored.
  • part of the surfactant mixture mentioned in Example 1 was added to the dyeing liquor of leather A 1, while this mixture was not added to the dyeing liquor of leather B.
  • Example 3 the procedure was as in Example 1, in Examples 7 to 9 as in Example 2. The results were comparable. See the table below for details.
