Definitions
- the invention relates to the use of bisulfite-blocked ethers Polyisocyanates as tanning agents.
- the tanning transforms animal skins into leather by cross-linking the collagen.
- One of the most important characteristics of leather is that of untanned hides increased shrinkage temperature, i.e. the improved hot water resistance, and the white appearance (non-transparent, non-pigment-like) after drying.
- the type of tanning that is still dominant today is chrome tanning using chromium (III) compounds under the influence of OH ions cross-linking covalent bonds with the carboxyl groups of collagen be formed.
- the available with polyfunctional vegetable tannins By contrast, hydrogen bonds to the amide groups of collagen are a lot weaker, which can also be seen in a moderately increased shrinking temperature affects.
- Aliphatic aldehydes, e.g. Glutaraldehyde leading to a Cross-linking via the primary amino groups of collagen has been called Tanning agents recommended (U.S. Patent 2,941,859).
- the resulting aldimines can reversibly react back to aldehyde and amine in the presence of water.

- Suitable polyisocyanates A are modified by aliphatic or Polyisocyanates prepared with cycloaliphatic diisocyanates with uretdione and / or Isocyanurate, urethane and / or allophanate, biuret or oxadiazine structure, such as they for example in DE-OS 1 670 666, 3 700 209 and 3 900 053 and in the EP 336 205 and 339 396 are described by way of example.
- Suitable polyisocyanates are e.g. also the ester group-containing polyisocyanates, e.g.
- the use of monofunctional and more than difunctional isocyanates in both cases is preferably to a maximum of each 10 mol%, based on all polyisocyanates A, limited.
- the polyether alcohols B are accessible in a manner known per se by alkoxylation of suitable starter molecules. Any mono- or polyhydric alcohols with a molecular weight of 32 to 250 can be used as starter molecules to produce the polyether alcohols. Monofunctional aliphatic C 1 -C 18 , preferably C 1 -C 4 alcohols are preferably used as starter molecules.
- the use of methanol, butanol, ethylene glycol monomethyl ether or ethylene glycol monobutyl ether as starter is particularly preferred.
- Alkylene oxides suitable for the alkoxylation reaction are in particular Ethylene oxide and propylene oxide, which are in any order at the Alkoxylation reaction can be used. Any other epoxies such as butylene oxide, dodecene oxide or styrene oxide can also be used become. Pure polyethylene oxide alcohols are particularly preferred.
- Polyalkylene oxide alcohols containing ester groups can also be used.
- Suitable polyalkylene oxide alcohols containing ester groups are OH-terminated polyester ethers which, by reacting aliphatic C 2 -C 8 -dicarboxylic acids or their esters or acid chlorides with polyethers from the group consisting of polyethylene oxides, polypropylene oxides, their mixtures or mixed polyethers, with 0 per OH equivalent of the polyether, 8 to 0.99 equivalents of carboxyl groups or their derivatives are used, are available and have an average molecular weight below 10,000, preferably below 3,000.
- the NCO-reactive components C which may also be used include Common mono- to tetrafunctional building blocks used in polyurethane chemistry such as alcohols, amines, amino alcohols and mercaptans with molecular weights below 6,000, preferably below 2,000, e.g. Polyesters, polyether esters and polycarbonates, unless they fall under definition B.

- the controlled addition of sodium or potassium hydroxide is also generally possible (but uncommon).
- Magnesium oxide is particularly preferred.
- the reaction products to be used according to the invention can be used as a substitute for mineral tannins are used. Generally used Amounts of 1 to 20, preferably 3 to 15% by weight of reaction product, based on sheer weight.
- the serve with the implementation product tanned leather with shrinking temperatures above 70 ° C, preferably above 75 ° C, as a preliminary stage (analogue wet blue) for retanning with synthetic organic polymers (incl. resin tanning agents) or vegetable tanning agents.
- the leather can of course still be colored and greased.
- the tanning with the Reaction products to be used according to the invention are particularly good at pH values of 4 to 10, preferably 5 to 8. You don't have to pick still pickle. Pickling can also be beneficial to achieve a softer leather his; even pimples don't bother.
- reaction products to be used according to the invention can also be used in this way use that only up to a shrinking temperature of 65 to 70 ° C tempered. This gives colorless leather (wet white), which is then mineral-tanned and with synthetic organic polymers or vegetable tanning agents can be retanned.
- the percentages in the following examples relate to the Weight and on nakedness / leather.
- the following examples contain an additional component C or 10 mol% trimerized HDI (22.1% NCO). Production analogous to example 1.

- Example A-1 The procedure was analogous to Example A-1, the reaction product from Example 7 (10% in each case) being used as the active ingredient and the truncating agents used varying.

- a ashed bare beef was decalcified as follows: 100% water (35 ° C) and 2% ammonium sulfate; after 30 minutes, 1% Polyzym 202 was added, the mixture was run for 60 minutes (pH 8); then the fleet was drained.
- Pretanning was carried out as follows: 50% water (30 ° C.) and 10% reaction product from example 7, after 90 minutes addition of 0.5% magnesium oxide, after 7 hours addition of further 0.5% magnesium oxide. When left to run overnight, the pH was 7.2.
- the leathers were unloaded, rolled over, on the overnight Bock beaten, vacuumed the next day, stolled and dried out hanging.
- the chrome-free leather was full and soft - similar to the chrome-tanned one.
- Both leathers can be dyed very well.
