Definitions
- Chrome, vegetable and / or synthetically tanned leather can be dyed using this process.
- Preferred alkylene oxides are ethylene, propylene and / or butylene oxide.
- Preferred non-oxyalkylated starting amines of the formula (II) are ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, hexaethylene heptamine or mixtures of these amines.
- the amines of the formula (I) are used, for example, in an amount of 1-30, in particular 5-15,% by weight, based on the weight of the dye.
- the amines of the formula (I) can be brought into contact with the leather before and after dyeing or simultaneously with the dye. They can also be incorporated into commercially available dye compositions.
- the leather is dyed in a known manner in an aqueous medium. Between 50 and 1000% by weight of water are used, based on the fold or dry weight. Depending on the substrate, desired shade and depth of color, the amount of dye available is between 0.01 and 15% by weight based on the fold or dry weight of the leather.
- the pH of the dye liquor is preferably between 4.0 and 7.0.
- the auxiliaries improve the absorption behavior of the dyes, the liquor consumption and the water droplet resistance of the leather.
- the effects of the aids occur in a wide variety of leather types such as chrome leather, synthetic and / or vegetable retanned chrome leather, purely vegetable tanned leather, split velor or nubuck.
- Wet blue leather is retanned (in 200% by weight of water) with a mixture of 3% by weight of a condensation product of a naphthalenesulfonic acid with formaldehyde and 3% by weight of a vegetable tanning agent. 0.2% by weight of the addition product of diethylene triamine with 2 mol of propylene oxide are used for coloring together with 2% by weight of the dye (A) in 250% by weight of water. After 20 minutes of dyeing at 40 ° C, acidified with 2% formic acid, the leather greased and finished. The percentages by weight relate to the fold weight.
- the staining is e g aler and full than that of the leather which has been dyed with the same amount of dye without aids.
- the retanned chrome leather is replaced by purely vegetable-tanned leather (15% mimosa, 15% quebracho on paw weight), the auxiliary agent by 0.4% by weight of the addition product of ethylenediamine and 3 mol of propylene oxide and dye (A) by 4 % By weight of the dye (B), there are corresponding effects in comparison to dyeing without auxiliaries.
- Example 2 if the auxiliary is allowed to run 5 to 10 minutes before the dye is added, the effects are corresponding.
