Artificial fancy yarns made from a core thread and a wrap-around thread are made using known methods produced on bell spindles, ring spindles or in spinning pot spinning, with the wrapping thread at a higher speed than the core thread is fed. The present proceedings refers only to spinning pot spinning. According to German patent 625 782 and the U.S. Patent 2,079,524 relating to spin pot spinning is disclosed in the spin pot on and from the outgoing thread guide funnel, in addition to the freshly spun core thread, a freshly spun thread Wrapping thread fed at greater speed, which is in the up and down Funnel wraps around the core thread. This creates more or less uniform yarns.

According to the invention, the freshly spun wrapping thread is in such a method freshly spun core thread in its vibration zone between a fixed thread guide and fed to the up and down thread guide funnel at an angle of 30 to 90 °.

As is well known, forms between the up and down thread guide funnel during spinning pot spinning and the fixed thread guide arranged above this, a balloon, which moves with the movement of the thread guide funnel changed by constantly getting smaller and larger. Will now be the freshly spun wrapping thread fed to this thread balloon, so are created by the fed Thread in this itself tangles or knobs. The size, i.e. H. the length and the thickness these knobs are not only the size of the balloon-like bend of the core thread, but also depends on the knobs formed one after the other. This creates a twisted one Knob thread, the knob of different sizes, thicknesses and spacing, and that in very irregular Way. Such threads or yarns are irregular in nature and spacing Nubs are often required because the fabrics produced with them have irregular nub patterns, i. H. show no repeating patterns at certain intervals.

The threads may be stretched by various amounts before they join together; they too can have different deniers and different numbers of single threads.

In the drawing, an example of an apparatus for carrying out the method according to the invention is shown schematically, in elevation and partially in section. After that, two methods of making an artificial one

Threads 1 and 2 by pressing viscose using pumps 5 and 6 through two nozzles 3 and 4 in a precipitation bath 7 is spun. The two threads are fed by two godets 8 and 9 over two guides 10 or 11 pulled out of the bathroom. From the godets 8 and 9, the two threads run over two more Galettes 12 or 13. Each of the two threads is between the two godets over which it runs, stretched. The thread 1 runs from the godet 12 via the fixed thread guide 14 to the funnel 15 of the spin pot 16 down. The thread 2 runs from the godet 13 to the thread 1 in its oscillation zone (balloon) between the thread guide 14 and the up and down funnel 15 and is there wound around the thread 1, whereupon both threads together run through the funnel into the spinning pot, which is turned in the usual way to get a To form spider cake.

A particular example of the application of the device is as follows. Pumps 5 and 6 deliver 6.2 and 20.6 g per minute, nozzles 3 and 4 have 48 or 60 holes, each 0.076 mm in diameter. The viscose contained 7.5% cellulose, 6.0% sodium hydroxide and had a salt number of 5.5. After exiting the nozzles, the threads remained 45.72 cm in the spinning bath, which contained 10% acid, Contained 1.3% zinc sulfate and 20% sodium sulfate. The bath was kept at 48 ° C; its surface tension was 40Dyn. The two godets 8

and 12, around which the thread 1 was passed, had diameters of 10.8 and 12.1 cm and became driven at a speed of 54 or 70 revolutions per minute. The two others Godets 9 and 13, around which the thread 2 was guided, both had 17.1 cm in diameter and were driven at 54 and 70 revolutions per minute. The spinning pot into which the threads will eventually go ran, had a diameter of 16.5 cm and was driven at 7000 revolutions per minute.

Claims (1)

Claim: Process for the production of an artificial effect yarn from a freshly spun core thread and a freshly spun wrapping thread at the spinning pot, in which the wrapping thread is fed to the core thread at a higher speed, characterized in that that the wrapping thread (2) the core thread (1) in its vibration zone between the fixed thread guide (14) and the up and down going thread guide funnel (15) is fed at an angle of 30 to 90 °.
