Definitions

the ratio of components (A): (B) in the tanning liquor is preferably 85: 15-50: 50 percent by weight.
the components can be added to the fleet separately or in the form of a made-up product.
the sulfosuccinic acid esters (A) are prepared in a known manner by esterification of maleic anhydride with 1 to 2 equivalents of the desired esterification component and subsequent reaction with an amount of a sulfite or bisulfite which is approximately equivalent to the maleic anhydride. Fat residues with 12 to 24 carbon atoms and compounds containing hydroxyl groups are suitable as esterification components
the fat residues can be saturated or unsaturated, straight or branched chain. They can be derived from fatty alcohols, branched chain alcohols produced by oxosynthesis, or fatty acid mono- or diglycerides e.g. B. C 12 -C 18 coconut fatty alcohol, C 16 -C 18 tallow alcohol C 8 -C 24 oxo alcohol, C 16 -C 18 tallow fatty acid monoglyceride, or of adducts of 1 to 6 moles of alkylene oxide to the fatty alcohols or fatty acid glycerides mentioned or Fatty acids, for example the adduct of 2 to 3 moles of ethylene oxide with C 16 -C 18 tallow fatty alcohol or from 4 to 6 moles of ethylene oxide with a C16-C24 fatty acid mixture or of 2 moles of ethylene oxide with a C 12 -C 18 fatty acid mixture.
the sulfosuccinic acid esters are used in the form of their salts,
Suitable emulsifiers (B) which are used in combination with the sulfosuccinic acid esters (A) are, for example, the adducts of 5 to 25 mol of ethylene oxide with C 8 -C 20 fatty alcohols or alkylphenols such as C 12 -C 18 coconut fatty alcohol + 8 EO , C 16 -C 18 tallow fatty alcohol + 20 EO, nonylphenol + 9 EO, or the sulfates of the adducts of 1 to 6 mol ethylene oxide with C 8 -C 20 fatty alcohols, fatty acids or fatty acid alkanolamides, for example the sulfates of C 12 - C 18 coconut fatty acid ethanol amide + 2 EO, C 8 -C 16 fatty acid ethanol amide + 2 EO or C 12 -C 18 coconut fatty alcohol + 5 EO in the form of their alkali or ammonium salts, preferably sodium salts.
the sulfosuccinic acid esters are added to the tanning or retanning liquors together with the emulsifiers before, during or after the addition of tanning agents, depending on the leather type desired, 0.1 to 6.0 percent by weight, preferably 0.5 to 4.0 percent by weight, of active substance, based on the nakedness - or fold weight can be used.
the fleets are characterized by good durability. Leather or fur skins of very good softness are obtained. The solid grain is significantly improved compared to the commonly used sulfitation products.
sulfosuccinic acid esters (A) and emulsifiers (B) can be used together with conventional ones
Electrolyte-resistant fatliquoring agents such as sulfited oils, for example fish oil, or by sulfochlorination and subsequent saponification of unsaturated fatty acid esters, such as tallow fatty acid methyl ester, or long-chain paraffins, for example chloroparaffin sulfonate, are used in the tanning liquor.
Base material cowhide chrome-tanned, rebate thickness 1 mm
Base material cowhide, chrome-tanned fold thickness 1.6 mm
