Definitions
- the present invention relates to an aqueous composition for pre-tanning skin bumps, a method for pre-tanning skin bumps and the leather pretanned by the present method.
- the mineral and especially the chrome (pre) tanning is of great importance for the production of leather and fur.
- the chromium salt-containing treatment baths that arise during the pre-tanning and the actual tanning process represent a large load factor for the waste water.
- alternative processes are sought which are ecologically harmless on the one hand and on the other hand equal to the mineral tanning in terms of the leather qualities achieved.
- DE-A-3 811 267 discloses a process for the production of semi-finished leather products by pretanning, in which a mixture of a dialdehyde and a specific hydroxy compound is used as the tanning agent formulation.
- DE-A-190 702 describes a process for decalcifying skins, in which the skins are soaked in a bath of sulfur and a carbohydrate which is in alcoholic fermentation.
- a combination product containing a reductive saccharide with a dextrose equivalent of 10 to 100 and an aliphatic dialdehyde containing 2 to 8 carbon atoms is a pretanning agent which is followed by a non-mineral, in particular chromium salt-free tanning Allows production of wet white leather material.
- pretanning agent which is followed by a non-mineral, in particular chromium salt-free tanning Allows production of wet white leather material.
- good results with regard to pretanning can be achieved with the aqueous composition according to the invention, the leather having a high shrinking temperature.
- Suitable reductive saccharides with a dextrose equivalent of 10 to 100 are the usual aldoses or ketoses, especially mono- and disaccharides, but also oligo- and polysaccharides.
- the dextrose equivalent is the amount of saccharide calculated in grams, which corresponds to 100 grams of dextrose in terms of reducing power.
- compositions according to the invention preferably contain mono- or disaccharides.
- Suitable monosaccharides are e.g. Glucose, fructose, mannose, arabinose and ribose. Sucrose, maltose or lactose may be mentioned as representatives of the disaccharides.
- Monosaccharides are preferred for the compositions according to the invention. Aldoses are particularly worth mentioning here, with glucose being of particular interest because of its easy accessibility and availability in technical quantities. So-called glucose syrups with a dextrose equivalent of 20 to 90, preferably 40 to 80, are particularly suitable because of the low price.
- dialdehydes or mixtures thereof which have 2 to 8 carbons and structurally saturated aliphatic C-C linkages can generally be used as dialdehydes.
- Examples include glyoxal malondialdehyde, succindialdehyde, glutardialdehyde, adipindialdehyde, pimeline dialdehyde and octane dialdehyde.
- Preferred representatives are succindialdehyde, glutardialdehyde, adipindialdehyde and glyoxal, of which glutardialdehyde is of primary interest.
- the dialdehydes are usually available as commercially available dialdehydes containing 25 to 50% by weight of water.
- aqueous compositions which contain 0.05 to 0.19 mol of component (a) per mole of component (b).
- aqueous composition according to the invention is expediently prepared by dissolving component (a) in water at a temperature between 15 and 60 ° C. and then adding component (b) to the clear solution obtained.
- the aqueous composition thus obtained is liquid and has good storage stability. If necessary, it can also be dried.
- the aqueous composition according to the invention is suitable on its own as an excellent pre-tanning agent for all hides and skins and serves very particularly as a preliminary stage for the production of wet white leather and furs.
- the pre-tanning is carried out, for example, by treating the pickled pelt material with the aqueous composition according to the invention and then tanning the material thus obtained in the usual way with a mineral tanning agent or, preferably for the production of wet-white material, with vegetable or synthetic tanning agents.
- the present process can also be used to produce finished tanned leather.
- a clear, bright solution is obtained which has a pH of 3.9-4.2.
- the dry content is 50%.
- 100 parts of a pickled calf pestle are treated with 1.5% of the agent prepared according to Production Example 1 in a rolling barrel for 8 to 16 hours at 25 ° C. With powdered sodium hydrogen carbonate or sodium formate, the pH is adjusted to 4.0.
- the leather treated in this way (wet white leather) is dewatered and folded to the desired thickness.
- This pre-tanned leather is ideally suited for further processing with mineral, vegetable or synthetic tanning agents to produce leather free of heavy metals.
- a clear, bright solution is obtained which has a pH of 3.9-4.2.
- the dry content is 50%.
- a clear, bright solution is obtained which has a pH of 3.94.2.
- the dry content is 50%.
