contains, in a mixture with a surfactant of formula (IV) or (IVa) quaternized with an R4 or Rw releasing quaternizing agent.

The quaternization conditions for the mixture then preferably correspond to those for the quaternization of the wax.

For 100 parts by weight of total wax (a), primarily 10-100 parts by weight, advantageously 15-60 parts by weight, preferably 20-40 parts by weight of total surfactant (b), in particular cationic and / or amphoteric surfactant, are used.

The waxes to be used according to the invention are advantageously formulated as aqueous preparations which also contain the surfactants (b), preferably in the quantitative ratio indicated above. These aqueous preparations are essentially fine-particle dispersions. In concentrated aqueous preparations of the waxes according to the invention, the dry matter content is preferably in the range of 15-50% by weight. If necessary, the preparations according to the invention can be diluted with water to dilute stock dispersions before application from an aqueous medium. If desired, the aqueous preparations according to the invention may also contain other customary additives, such as antifreeze or fungicides.

The waxes and wax preparations to be used according to the invention are for the finishing of fiber material, in particular textile material from an aqueous medium, to improve machine processability, in particular machine dry processing, e.g. the sewability and the roughening of flat or tubular textile goods and the processability of thread (winding, rewinding, weaving, knitting, etc.).

Any textile material, such as is found in the textile industry, is suitable, namely both natural and synthetic and semi-synthetic materials and their mixtures, in particular natural or regenerated cellulose, natural or synthetic material containing polyamide, polyester, polyurethane and polyacrylonitrile, and mixtures thereof . The material can be in any form of processing, e.g. as loose fibers, filaments, threads, skeins and spools, fabrics, knitted fabrics, nonwovens, nonwovens, felts, carpets, velvet, tufted goods or semi-finished goods and also artificial leather. Cross-wound bobbins, textile webs or tubular textile goods, in particular knitted tubular goods, are preferably equipped.

The equipment is expediently carried out from an aqueous, weakly acidic to weakly alkaline medium, in particular in the pH range from 4-9, preferably under almost neutral to weakly acidic conditions, in particular in the pH range from 5-7.5. The concentration of the preparations according to the invention, based on the substrate, can vary within wide limits depending on the nature and nature of the substrate and the desired effect and is advantageously in the range from 0.25-2, preferably 0.5-1.5%, dry matter [ Wax (a) + surfactant (b)], based on the dry weight of the substrate.

The use according to the invention generally has the character of a non-permanent finishing and is advantageously carried out as the last finishing stage of the material before further mechanical processing, preferably following an optical brightening process and / or dyeing process, optionally after an additional treatment, e.g. permanent equipment of the fiber material. The equipment can be made by any conventional method, e.g. after impregnation process or after pull-out process. With pull-out processes, processes from both long and short fleets can be considered, e.g. with liquor ratios in the range from 100: 1 to 0.5: 1, in particular between 60: 1 and 2: 1. The application temperature can also be at customary values, for example in the range between room temperature and 60 ° C., preferably in the range from 25 ° C. to 50 ° C. The impregnation can be carried out by conventional methods, e.g. by diving, padding or spraying. After the impregnation process or after the pull-out process, the treated goods can be dried in the usual way, e.g. at 30 to 180 ° C, preferably 60 to 140 ° C.

The preparations to be used according to the invention, in particular those which contain the surfactants of the formula (III), are notable for excellent resistance and, in particular, are stable and unchanged even under strong dynamic loading of the liquor and / or textile material and are therefore particularly suitable for the equipment of textile webs and hoses in nozzle dyeing equipment, even in those in which extremely high shear forces are effective. The preparations provided according to the invention are also very well suited for the wet waxing of packages. In this case too, the dynamic load is high

- Production of the cationic wax K1

2240 parts of oxidized polyethylene W1 are melted at 110 ° C and 112 parts of 3- (dimethylamino) propylamine are added. The temperature is then raised from 110 ° C. to 180 ° C. under nitrogen within 8 hours and kept at this value for 10 hours. The mixture is then cooled to 150 ° C., evacuated (26 mbar) and stirred for 30 minutes under this vacuum. A total of approx. 28 g of distillate with an amine content of 36% are obtained. The acid number of the condensation product is then determined. It is approximately 3.0. The mixture is then vented with nitrogen and cooled, and 111 parts of dimethyl sulfate are added dropwise at 110 ° C., which corresponds to the amount required for the quaternization of the amidamine groups which can be determined by determining the decrease in the acid number. After 30 minutes at 110 ° C., the cationic quaternized wax K1 obtained is unloaded.

Analogously to that described in Example C, the dispersions according to Examples 2-12 are used.

To test the sewability, two pieces of textile material, which is equipped and thermally treated as described, are kept in a normal climate (65% relative air humidity and 20 ° C) for 24 hours and then both finished pieces are sewn with a Pfaff lockstitch sewing machine type 483 at one Test speed of 4800 stitches / minute sewn together as a test (ie without sewing thread). The puncture force of the sewing needle is recorded by a strain gauge bridge located under the textile material and under the puncture site and registered by a UV recorder connected to it. the puncture force is only read when the number of turns of the sewing machine (4800 turns / minute) has become approximately constant after a start-up time. The zero value of the UV recorder is calibrated when the machine is running with the same number of revolutions, but without fabric. The average value of the puncture force is determined on ten seams of 100 stitches each. The sewing needle used is an SES / 80 (small ball point) needle from F. Schmetz GmbH (special factory for sewing machine needles, 5120 Herzogenrath, Germany) (see pocket book of sewing technology F. Schmetz, 1975).

Application example D

100 kg of mercerized cotton yarn, in the form of strands, are treated with 2% (2 kg) of product according to Example 9.

Apparatus: Hugdson, Walker, Davis staining apparatus (spray)

Liquor: 10001 pH: 6.0

Treatment time: 20 minutes, 40 ° C

After the treatment, drying and cross-wound bobbins are made. The fiber-metal friction coefficients f are then determined (Rotschild F-Meter). Test conditions:

Wrap angle: 120 °

Preload: 15g

Take-off speed: 50m / min and 100m / min.

The material treated with the dispersion according to Example 9 has a significantly lower f-value than the untreated one.
