In the technical production of staple fibers, it is desirable, for technical and economic reasons, to combine dip x'rcduction of various hours of work from one or more spinning machines into a large cable, which is of the order of thousands of -ii ' äden ent «Mit, and this large bundle of n -ü'aden i / leichzfiitip; to stretch as well as the number of working methods / fUx'de anpjewenüet, in order to achieve the bridging of the non-oriented thread through the application of arms before or during the Ox'ientir: run '; stage, for example by the yarn over or between hot hats or between hot zones or around hot pins or the like, g ^: f; ^; hrt is «Itieii'f: Arboitswciaqn proved to stretch from

of large or strong cables used in the production of Staple fibers are required, unsatisfactory. It is difficult to uniformly heat all the filaments within a large cable using hot surfaces or zones to achieve, and usually be at it α non-uniform elongation results are obtained. Such Poorly or unevenly stretched fibers have varying physical properties and, since the non-oriented ones and partially oriented fibers are colored to much darker shades than the oriented ones Fibers, are they so rider your wishes and detrimental, if the batch product for colored 'iaren odex' Toxti!

The task of discovery is to acquire one novel method for stretching large or B.arkon cables from essentially non-oriented irolyester threads, which are stretched to a very uniform Cable iuit excellent physical properties five to

The method according to the invention is characterized in that '? a cable made of essentially non-oriented polyester threads through a first at a ^; e: - the inert bath is kept at a temperature of around 80 to 100 ° C, cools the threads to a temperature of around 40 to 60 C and then stretches the cable at a stretching amount of at least twice its original length, wherein the cable is "Preferably, the first inert bath at 80 ° G held et'.va füart r by a second at a temperature of about 80 to 100 C-held, inert bath, after which the cable is cooled to about 55 ° C and then is stretched at a stretching amount of about 2 to 6 times its original length while it is passed through a second inert bath maintained at about 90 ° C, if the stretching process is carried out in the manner described above the l ^? The threads in the cable impart uniform elongation and excellent physical aging will be achieved.

Jn the invention, the reaching at the Ai.sfünrung of "Ve -fahrens according to application baths any medium procedures can be applied, which is opposite the ädenunschädlich J- ^P" Preferably, aqueous baths are used, since their use is technically and economically advantageous and to achieve satisfactory results Finishing agents can be incorporated into each of these baths, or they can be applied to the threads at a later time. These finishing agents can include antistatic agents, wetting agents, plasticizers, sensitizers or the like.

Practical working methods are shown in the drawing for the practical implementation of the method according to Invention explained. As shown in i'ig * 1, that will Cable to be oriented over rollers 1 to 8 and 11 to each guided, with the rollers 1 to 8 at one given uniform circumferential speed are, while the rollers 11 to 18 have at least twice as large a uniform unifangspeed.
