Definitions
- the present invention relates to cationic emulsified fatliquor containing active components
- Emulsifiers based in each case on the total amount of active components,
- the present invention relates to a process for the preparation of the cationic-emulsified fatliquoring agents according to the invention and their use for the fatliquoring of tanned hides.
- Emulsifiable fatliquors also called lickers, play an important role in leather production.
- Greasing agents are used in leather production to soften the leather, to increase its fullness and to increase the protective effect against moisture, dirt and undesirable chemical influences.
- An overview of classic fatliquoring agents can be found in Herfeld, "Bibliothek des Leders", vol. 4, p. 13 (1987).
- Commercial fats usually consist of chemically modified native fats, fatty oils, waxes, resins and derivatives, petroleum fractions or their derivatives, cf. Herfeld, "Library of Leather", Vol. 4, p. 59 (1987).
- cationic greasing agents are often used.
- the "top” or “cationic attachment” is usually the last step in retanning or greasing. With a suitable method of working, it causes deepening of color when dyeing with anionic dyes, formation of a desired slimy handle or so-called “fat handle”, reduced water absorption for controlling the binder penetration during dressing, and glossing for the sanding of suede leather or nubuck leather, see. Herfeld,
- Known cationic fatliquors consist of preparations from natural or synthetic neutral oils with cationic emulsifiers. Such lubricants are also referred to as cationic emulsified. Salts of fatty amines, for example the acetates, derivatives of the fatty acid amides, for example the alkylation products, in particular distearyldimethylammonium chloride, and alkanolamine ethers which are obtained by reaction of alkyl chlorides with ethanolamines are known in particular. Formulation difficulties often arise from the low water solubility of the cationic emulsifiers.
- solubilizers such as co-emulsifiers such as e.g. to improve amphoteric emulsifiers from the family of the phosphatides.
- solubilizers such as co-emulsifiers
- a mixture of equal parts of soy lecithin and stearylhydroxyethylethylenediamine acetate is known as a cationic licker to improve the tanning of chrome leather, I. Mölering et al. , "Procedure of the end of the area",ticianliche Verlagsgesellschaft, Stuttgart, p. 357, 1954.
- the object of the present invention was therefore to provide new cationically emulsified fatliquoring agents which do not have the disadvantages of the prior art stated above, in particular not the formation of fat rashes which can be seen immediately after drying, and fat rashes which only become visible after a certain time, and which show a good and balanced application profile. Furthermore, it was an object of the present invention to provide a method for producing new cationically emulsified fatliquors, and finally it was an object of the present invention to produce new, greased leather goods by using the fatliquoring agents according to the invention and a method for fatliquoring tanned skins Production of the leather goods according to the invention.

- Vegetable oils include, for example, rapeseed oil, coconut oil, copra oil, peanut oil, corn oil, corn oil, safflower oil, soybean oil, olive oil, rape oil and sunflower oil.
- Synthetic oils essentially consist of long-chain, in particular Cie-C ß o-hydrocarbons, which can be saturated or can also have one or up to 4 CC double bonds.
- the synthetic oils advantageously contain up to 20% by weight of Ci 6 -C 3 o-hydrocarbons with one to four CC double bonds.
- the cationically emulsified fatliquoring agents according to the invention contain the active components a) to c).

- Another example of such mixtures are mixtures of two or more different modified oils, and a further embodiment is mixtures of two or more differently modified derivatives of the same oil as the active component of the fatliquoring agents according to the invention.

Mixing takes place at room temperature or at a slightly elevated temperature, but advantageously not above 100 ° C. You can also change the temperature during mixing, i.e. increase or decrease. So it is possible to start mixing at room temperature and then after 1 to 10 hours for a short or long period, i.e.
- the cooling is followed by stirring at room temperature.

Use without conventional fatliquors of native or synthetic origin is preferred, in particular without conventional fatliquoring agents of synthetic origin.
- the skins can be retanned according to the conditions known per se. One usually works with skins in 50 to
- Fatliquor based on the fold weight, can be added.
- the pH is adjusted to 3.0 to 7.5 using buffers, for example formic acid / sodium formate or sodium bicarbonate.
- Optional steps of the method according to the invention are washing and rinsing steps between the individual steps (tanning, retanning or retanning + fatliquoring, fatliquoring).
- the hides tanned by the process according to the invention have special effects, for example a particularly low tendency to form fat rashes, in particular also a particularly low tendency to form fat rashes in places which are difficult to access.
- Another aspect of the present invention is therefore the leather and leather surfaces greased using the fatliquoring agents of the invention. Advantages are the generally very good, in particular very uniform, colorations of the leather surfaces according to the invention, furthermore the good firm grain and a pleasantly narrower, i.e. soft and sliding grip.
- Example 1 Chemical modification of native rapeseed oil-fish oil mixture with air
- the mixture was first heated to 60 ° C. and a further 10 minutes later to 95 ° C.
- the mixture was stirred at 150 ° C. for 150 minutes and then cooled to 60 to 70 ° C. Now, with vigorous stirring (1400 revolutions / min), 80-100 l / h of air were blown through the solution until no more water distilled off.
- the mixture was then heated to 110 ° C. and air continued to be blown through. If an exothermic reaction was observed, i.e. as the temperature increased, the temperature was lowered to 95 ° C. As soon as the exothermic reaction subsided, the mixture was heated again to 110 ° C. It was blown for 6 hours. It was then cooled to room temperature again.
- Example 2 Chemical modification of native rapeseed oil with hydrogen peroxide
- the molar conversion of rapeseed oil to rapeseed oil epoxide was 1.0 to 0.4.
- Example 3 was reworked with the native beet oil-fish oil mixture used as the starting material in Example 1 instead of with oxidized beet oil-fish oil mixture.
- the mixture was then greased with a mixture of 4 parts by weight of commercially available fatliquor (Lipoderm Licker PN, BASF Aktiengesellschaft) and 2 parts by weight of the fatliquor from Example 3.
- the liquor was then adjusted to a pH of 3.5 to 3.8 using formic acid, the leather briefly rinsed cold and further processed as usual.
- a leather was obtained with a very good and even color, good firm grain with good fullness and medium softness.
- the leather surface had a slim handle.
- Example 6 was repeated, but using the product from Example 4 instead of the product from Example 3.
- the leather obtained also showed excellent leather properties.
- Example 8
- Example 6 was repeated, but using the product from Example 5 instead of the product from Example 3.
- the leather obtained did not have the same leather properties as in Example 6.
- the leather surface had an uncomfortably greasy feel.
- the greasing agent was unevenly distributed in and on the leather surface, recognizable by the more uneven (uneven) coloring, the visible grease stains and the uneven softness of the leather.
- a conventional fatliquoring agent (Lipoderm licker ® AI, BASF Aktiengesellschaft) was then greased and 4 parts by weight of the fatliquoring agent of Example 3 with a mixture of 8 parts by weight.
- the liquor was then adjusted to a pH of 3.5 to 3.8 using formic acid, the leather briefly rinsed cold and further processed as usual.
- the result was a leather with a very good color, good firm grain with a very good fullness and excellent softness with an elegant handle.
