Example 1

12 kg of pure wool gabardine piece goods are placed simultaneously on a reel runner in 4001 liquor as follows avivated and colored:

The liquor is at 40 ° C with 500 g of the emulsion A «° charged with 150 g of formic acid, 15 g of dye A, 75 g of dye B and 30 g of dye C, within Bred to a boil for 45 minutes and cooked for 40 minutes. The pH of the dyebath is during of dyeing 4.6. The product has a soft feel and an even color in a Bordotoa receive. «

Emulsion A is obtained by adding 300 g of triethanolamine / sodium salt of N-stearoyl-N-methylaminoacetic acid (Component a), 280 g of a component b), the preparation of which is described below is, 30 g Polyglycerin Talgester (component c) and 120 g condensed water at 50 to 60 ° C up to Stir homogenization.

The triethanolamine / sodium salt of N-stearoyl-N-methylaminoacetic acid can be represented as follows:

660 g of sarcosine sodium (18%) are diluted with 220 g of condensed water. To this, while stirring, 301 g (1 mol) of stearic acid chloride and 130 g of sodium hydroxide solution (45 percent by weight) are added at the same time. Acid chloride and sodium hydroxide solution are allowed to run in at 25 to 30 ° C. at the same time, with the proviso that the reaction mixture always has a triazene-alkaline reaction. After the addition of 1 hour at 30 to 35 ° C is stirred and then the reaction mixture with methanol-water 1.51: stirred and heated to 6O ⁰ C (1: 1). It is then acidified with 300 ml of concentrated hydrochloric acid and left to settle overnight. Two layers are formed. The top layer is separated off, evaporated to 100% product on a water bath and initially partially mixed with 75 g of triethanolamine (Va mol) and then with 50 g of sodium hydroxide solution (40 percent by weight) (V ₂ mol) at 30 to 35 ° C with stirring.

Way of working

A mixture of (1), (2) and (3) is allowed to run in at 30 to 35 ^° C. within 3 hours and the mixture is stirred for a further 4 hours at 32 to 35 ^° C. After this, ice is added, Stirred homogeneously and then neutralized with the dilute sodium hydroxide solution to pH 8.2, whereby the temperature should not exceed 35 ° C. After neutralization, (5), (6), (7), (8) and (9) are added one after the other at 70 to 75 ° C. Then, at the same temperature, the amount of water specified above is adjusted and the mixture is bleached with hydrogen peroxide by adding in small portions. Finally, the reaction mixture is stirred for 12 hours at 7O ⁰ C.

A fabric made of copper rayon threads is finished with a liquor containing 25 g of emulsion B per liter on the padder. The tissue is o squeezed off to a weight increase of about 100 ° / and dried in an oven at 8O ⁰ C. This treatment gave the fabric a smooth, soft and full feel.
The emulsion B is obtained by thoroughly stirring a mixture of 250 g of ethylenediamine diglycol ether / sodium salt of N-oleyl-N-methyltaurine (component a), 300 g of a component b), the preparation of which is described below, 55 g of olive oil polypropylene glycol ester (component c ), obtained by esterifying olive oil with propylene glycol in the presence of a little KOH, 60 g of urea and 150 g of condensed water at 50 ° C until homogeneous distribution.

The free acid on which component a) is based is obtained analogously to the information in Example 1 by reacting 487 g of N-methyltaurine sodium (33%) with 299 g of oleic acid chloride and 120 g of sodium hydroxide solution (45% by weight), 220 g of condensed water in the presence of 1.5 g of methanol and 300 cm ^{3 of} concentrated hydrochloric acid.

To the free sulfonic acid obtained in this way of a-N-oleyl-N-methyltaurine is under Stirring at 35 ° C initially partially 74 g of ethylenediaminodiglycol ether and then 50 g of soda

Lye (40 percent by weight) was added. As a result, the salt formation has been carried out with the same V ₂ molar amount of organic and inorganic bases.

Component b) is produced in the following way:

Way of working

(1), (2) and (3) are presented and cooled ^{to -3 to -5 0 C.} Then (4) is added in small portions over the course of 4 hours, and then sulphonation is carried out over the course of 2/2 hours with stirring at -3 ⁰ C. The ice water is then added and the reaction mixture is stirred well for 1 hour. The mixture is then left to stand at 10 to 14 ° C. for 17 to 20 hours. After the 180 to 200 g lower layer consisting of water and sulfuric acid has been removed, the upper layer is ^{neutralized with (5) at 14 to 35 °} C. and stirred at 25 to 30 ^° C. for a further 2 hours. Then the solvent and residues of water are distilled off. The dry content of the thus obtained pure Fettsulfonats is 99 to 100 ° / _0th The product is bleached by addition of a little sodium hydroxide solution at a pH of 5.8 to 6.2 (l ° / _o solution) with 1 ° / o hydrogen peroxide.
