摘要： The present invention relates to a process for the simultaneous stretch-texturing of synthetic, at least partly thermoplastic filaments or yarns using false twisters, more especially friction false twisters wherein the ratio S.sub.2 /S.sub.1 between the tractive or tensile forces S.sub.1, acting on the filament before the false twister, and S.sub.2, acting on the filament after the false twister, is adjusted to from 1.0 to 1.4 by adapting the ratio between the rotational speed of the false twister and the rate of travel of the filament or yarn, and the denier-related twisting of the yarn is from 5 to 50% higher than the level of twisting which is normally applied in conventional false-twist texturing processes using a spindle and which can be calculated on the basis of the Heberlein formula. Moreover, the invention relates to a yarn produced by the afore-described process.

摘要： A false-twisting apparatus for producing crimps in filament yarns, comprising: a first group of endless belts each having a straightly extending region between two spaced pulleys; about which it is entrained a second group of belts arranged in vertically zigzag fashion relative to the belts of the first group and each belt of the second group having a straightly extending region between two spaced pulleys about which it is entrained. The straightly extending regions of the second group of belts are positioned in vertical zig-zag and parallel fashion relative to the adjacent similar regions of the belts of the first group the belts of the second group are driven to travel in a direction opposite to that of travel of each of the belts of the first group. Means, further, are provided for detecting the fluctuation in the tension of the filament yarns which are passed in successive contact with the contact surfaces of these straightly extending regions of the belts in zig-zag fashion; as are means for adjusting the positions of inlet and outlet guides of the filament yarns operatively coupled to said tension fluctuation detecting means; and means for adjusting the parallel distances between the respective straightly extending regions of the belts. This apparatus can be operated at a very high speed under a relatively low tension on the filament yarns and insures the production of evenly crimped yarns of high quality at low production as well as construction costs and can occupy less floor area.

摘要： An apparatus for false twisting threads has three spindles arranged to rotate about substantially parallel axes and fixed at the corners of a triangle centered on the mean path of the thread with friction elements carried by the spindles overlapping each other and means for moving a thread from a position outside the friction elements into a position where the thread follows a zig-zag path between the friction elements and is twisted thereby through an intermediate position where the thread first engages only some of the friction elements and is then moved into position for full rotation.

摘要： A novel process and apparatus for twisting filamentary material such as yarn is disclosed wherein yarn is twisted down stream of a heating means and intermediate of take-up and feed stations. Opposite sides of the yarn are contacted at successive points therealong thus gripping the yarn while both an advancing and rolling motion is imparted thereto. Such motion is imparted to the yarn in one physical embodiment of the invention by means of a pair of rolls provided with meshed teeth formed along circumferential surfaces thereof. The rolls in such embodiment are mounted in angular relationship to each other so as to permit the teeth of respective rolls to engage opposite sides of a filamentary piece of material passing between said rolls at opposite sides and at successive points therealong. Such contact along successive opposite portions of the yarn causes the yarn to take a continuous and essentially stable path between the rolls and enables a positive grip to be imparted to the yarn thereby overcoming the torque imparted to the yarn as a frictional twist component of the meshed teeth. The apparatus of the present invention may thus be characterized as a friction twist head and its method of operation a process for imparting false twist to filamentary material by frictional contact.
