Wenn die äthylenglykole mit OH-Endgruppen verwendet, und Garne nach dem Verlassen der Wirbeldüsen nach der 20 zwar insbesondere solche von einem Molekular-Tuftingtechnik in Teppiche eingearbeitet und mit gewicht von 6000 bis 30000. Diese werden dem PoIyvormetallisierten und sauren Farbstoffen angefärbt amid in einer Konzentration von 3 bis 25 % zugesetzt, werden, so erhält man ein streifiges Aussehen. Um Bei den nachfolgend beschriebenen Versuchen wirdsuitable; however, it is difficult to mix a uniform one with a previously prepared polyamide. Achieve staining, especially if the yarns This is an especially good way to make a renach the recently developed methods of vortex action between the polyamide and the polyglycol nozzle treatment can be made voluminous, such as keeping io as low as possible and also around a thersie z. B. in US Pat. No. 2,852,906 to prevent the degradation of the polyglycol. That are written. The polyamide yarns can be made from a mixture of thread-forming polyamide and polyester Vortex treatment with both pre-metallized ethylene glycol can verals from the melt in threads Color evenly with acidic dyes, be spooned, preferably immediately afterwards but the staining becomes uneven when the mixing takes place in the melt. The after yarns first textured and then colored. The following treatment stages can be the same Although the texturing process may be carefully directed as described above, As an additive for polyamides, the poly rings are used Changes in terms. If the ethylene glycols with OH end groups are used, and Yarns after leaving the vortex nozzles according to FIG. 20 are in particular those from a molecular tufting technique incorporated into carpets and weighing from 6,000 to 30,000. These are the poly-pre-metallized and acidic dyes colored amide added in a concentration of 3 to 25%, a streaky appearance is obtained. In order to carry out the experiments described below
