Definitions
- the present invention relates to an improved process for greasing, filling and waterproofing leather and furs, and to an improved greasing agent for leather ri3 furs.
- aqueous fat emulsions which are generally based on petrochemically produced or natural oils and fats. These are made water-emulsifiable by partial sulphonation or with the help of emulsifiers or solubilizers.
- DE-A 39 09 614 (1) relates to a process for greasing and waterproofing leather and furskins using sulfonated compounds of succinic acid with unsaturated fatty acids or their esters, amides or alkanolamides, for example a reaction product of oleic acid or of an oleic acid derivative with maleic anhydride in the presence of a radical initiator which was then sulfonated with sulfuric acid.
- a process for greasing, filling and waterproofing leather and furs which is characterized in that for this purpose ene adducts of maleic anhydride with unsaturated fatty acids having 12 to 24 carbon atoms, their carbon atoms to carbon atoms Alkyl or C 2 - to C __- alkenyl esters, their triglycerides, their amides, their mono- or di (C 2 - to C 4 -alkanol) amides, their mono- or dipolyether amides or their polyether esters or partially or completely En-adducts derivatized by reaction with amines or alcohols to form amides or esters.

- the unsaturated fatty acids have 12 to 24, preferably 14 to 18 C atoms and one or more olefinic double bonds.
- maleic anhydride is preferably added to each double bond, although this would certainly be possible since the double bond of the fatty acid is not saturated during the addition, but that of the maleic anhydride.
- unsaturated fatty acids is oleic acid (cis-9,10-octadecenoic acid), furthermore the trans-isomeric elaidic acid, laurolein- (9,10-eicosen-), eruca- (13,14-docosen) -) and the Selacholein- (15,16-Hexadecen-) acid called.
- Suitable fatty acids with 2 and more olefinic double bonds are mainly linoleic (9,10-12,13-octadecadiene) and linolenic (9,10-12,13-15,16-octadecatriene) acid call.
- esters of the unsaturated fatty acids e.g. Methyl, ethyl, propyl, butyl, 2-ethylhexyl, decyl, dodecyl, tetradecyl, hexadecyl, stearyl, hexadecenyl, oleyl, linolyl or linolenyl esters.
- the triglycerides of unsaturated fatty acids i.e. primarily natural fats and in particular oils, can also contain the predominant proportions, i.e. more than 50 mol%, preferably more than
- esters 75 mol%, based on the total fatty acids present in the mixture, containing the aforementioned unsaturated fatty acids as esters.
- unsaturated fatty acids for example, linseed oil, olive oil, castor oil, peanut oil, sesame oil, corn oil, sunflower oil, soybean oil, poppy seed oil, cottonseed oil, hemp oil and palm oil as well as the various animal fats and especially oils such as fish oil, whale oil and sperm oil are suitable.
- the latter also contains considerable proportions of esters with wax alcohols, including unsaturated alcohols.
- Particularly suitable fatty acid amides are the compounds which are unsubstituted on amide nitrogen.
- N-mono- or N, N-diethanolamides or -isopropanolamides can be used as mono- or di- (C 2 ⁇ to C 4 -alkanol) amides.
- Suitable mono- or dipolyetheramides are, for example, compounds substituted on amide nitrogen by polyoxyethylene groups with a respective degree of ethoxylation of 1 to 30, in particular 2 to 20.
- Suitable polyether esters are, for example, unsaturated fatty acids reacted with 1 to 30 mol, in particular 2 to 20 mol, of ethylene oxide.
- the amide or ester derivatives are prepared in a known manner by. Addition of the amine or alcohol to the ene adduct containing anhydride groups at temperatures between 20 and 200 ° C., preferably between 50 and 150 ° C.
- a catalyst for example p-toluenesulfonic acid, can be used for the addition.
- no more than one mole of amine or alcohol is used per mole of anhydride group.
- the addition can take place, for example, in toluene or in bulk, preferably in the same reaction medium as in the preparation of the ene adduct.
- alcohols such as methyl, ethyl, propyl, butyl, 2-ethyl Eth ⁇ exyl, decyl, dodecyl, tetradecyl, hexadecyl, stearyl, oleyl alcohol or alkoxylated fat or oxo alcohols or carbohydrates such as eg glucose can be used.
- C 1 -C 20 -alkanols straight-chain or branched C 1 -C 20 -alkanols, in particular C 4 -C 8 -alkanols, and Ca 2 -C 20 -alkanols reacted with 2 to 20 mol ethylene oxide and / or propylene oxide per mol alkanol are preferred.
- Amines which can be used are, for example, mono- or di-N-alkylamines such as n-butylamine, 2-ethylhexylamine, morpholine, piperidine or tallow fatty amine or amino acids such as sarcosine, taurine or iminodiacetic acid or amino alcohols such as iminodiethanol or hydroxyethylamine.
- Saturated or unsaturated secondary or in particular primary aliphatic amines having a total of 1 to 30, in particular 4 to 18, carbon atoms are preferred.
- the products described also have a hydrophobic effect, i.e. Leather and furs treated with them become water-repellent and only absorb small amounts of water.
- aqueous emulsions of the ene adducts to be used according to the invention contain no additional emulsifiers. It is known that leather and furs which have been treated with products containing emulsifiers have to undergo complex processes after treatment with these agents, e.g. an aftertreatment with polyvalent metal salts are subjected to in order to render the emulsifiers in the leather or in the fur skins ineffective, which cause a negative effect on the hydrophobizing effect of these products.
- the present invention also relates to fatliquoring, filling and waterproofing agents for leather and furs, which contain the described ene adducts of maleic anhydride with unsaturated fatty acids or their derivatives.
- the leather treatment compositions according to the invention are suitable for the treatment of all customary tanned hides.
- the tanned hides are usually deacidified before the treatment. They may have been stained before treatment. However, coloring can also only be carried out after the treatment according to the invention.
- the tanned skins are expediently mixed with the aqueous emulsions of the ene adducts in an aqueous liquor, which can be obtained by diluting the emulsions with water, at pH values from 4 to 10, preferably from 5 to 8, and temperatures from 20 to 60 ° C, preferably 30 to 50 ° C, treated for a period of 0.1 to 5 hours, in particular 0.5 to 2 hours.
- This treatment is carried out, for example, by walking in a company.
- the amount of emulsion required, based on the shaved weight of the leather or the wet weight of the fur skins, is 0.1 to 30% by weight, preferably 1 to 20% by weight.
- the fleet length i.e. the percentage weight ratio of the treatment liquor to the goods, based on the fold weight of the leather or the wet weight of the fur file, is usually 10 to 1000%, preferably 30 to 150% for leather and 50 to 500% for fur files.
- the pH of the treatment liquor is adjusted by adding acids, preferably organic acids, e.g. Formic acid, adjusted to a pH of 3 to 5, preferably 3.5 to 4.
- acids preferably organic acids, e.g. Formic acid, adjusted to a pH of 3 to 5, preferably 3.5 to 4.

- the total fleet length was 150%.
- the leather was then dyed with 1% by weight of a customary anionic aniline dye. Then it was adjusted to a pH of 3.8 with formic acid. Finally, washing, mechanical stretching and drying were carried out.
- the leather obtained was very soft, supple, well filled and evenly colored.
- the leather thus obtained was very soft and easy to grip.
- Chrome-tanned cowhide with a fold thickness of 1.8 mm which has been deacidified to a pH of 5.0 and dyed with 0.7% by weight of a conventional anionic aniline dye was drummed with 15% active substance of the emulsion from Example 3, based on fold weight, for 30 minutes at 40 ° C. in the tanning drum and then treated with 3% of a conventional synthetic tanning agent for one hour. Then the leather was brought to a pH of 3.6 with formic acid and finished as usual.
- the leather thus obtained felt pleasantly soft and easy to grip.
