Mixed Y / ring blenders, which were allowed with a hot water bath, do a temperature of 45 ± 2 ° C. for the aqueous emulsion. So much antistatic agent was added to the heated i / assar in the liisch pump that the oil-water emulsion contained about 15 $ oil. After mixing, the emulsion produced in this way was transferred to a hot water-heated storage container for antistatic finishing, which was equipped with devices was designed for roller application ooi 8 Bylon spinning positions. The storage container for rolling the coating onto the nylon fibers γ / iirde is kept at a temperature of 45 + 2 ° C. An equal sample of antistatic agent was taken. mixed in the same yieise at ambient temperature and transferred to a storage container which was kept at room temperature and was provided with means for rolling up the agent at eight nylon spinning positions arranged immediately next to it also taken from the heated storage tank over a period of three weeks and the ITylon fibers treated in this way were followed during the further Struck and Toxturier Terfaiirans · The results of the daily analysis of the application agent showed that the number of bacteria in the In the heated storage container SGü,000 organisms per Müp-izaeiler of the aqueous dispersion and 300 organisms per millimeter of the aqueous dispersion in the heated storage tank was in each case on average, and that the incipient and 1 · "ΨφΆ breaks in the fiber yarn during the hot stretching # 91 »* 2 texturing treatment for those with the heated one

There was no jiiiderimg in the emulsion stability, the! component entremiun-g or the chemical The settling of the heated application agent in the storage container was determined and the water content in the heated application agent was only reduced by 0.92 ° during the mentioned period of three boils *

Example 2 .

A series of experiments were carried out using the same equipment and procedures as in Example 1 with three additional antistatic applicators. The. .Results of these tests are shown in Table 1 below, the application agent 1 being a mixture of an acetylated Eoiioglycerides and ethoxy alcohol, the application agent 2 a mixture of Jetts acid esters and sulfonated peanut oil and the application agent 3 finally a mixture of sulfonated peanut oil and kieral oil; Table 1:

sicii ε-us the above-mentioned examples without further ado, brings äp.s novel process of the use of heated anti-static Auftrag'riittels for the application in textile materials i en the clear goal of a reduction in G-breakage in the Processing the yarn with it and providing a means of maintaining a uniform concentration of the antistatic coating agent on the yarn. These advantages, and never others, which are achieved by reducing the number of bacteria on the textile material, are achieved simply and at very low cost by adding simple heating systems to existing and known Selandlimgseinrichtung.
