Definitions

  • the invention relates to a method and an apparatus for making thick spots in a filament yarn.
  • JP-Hei-6-1733 At least one endless, synthetic, thermoplastic Filament yarn intentionally with random or regular to provide distributed thick spots.
  • the filament yarn wrapped around a roll, which over several springs is arranged on a holding element.
  • the filament yarn becomes one at certain intervals Thick place given up non-positively.
  • a device for performing this method has limited by an input delivery plant and an output delivery plant Stretching field, with a filament yarn in between a device to supply heat is arranged in the stretching field (DE 196 26 032).
  • This heat supply device is considered to be at least a disk driven via an axis of rotation with at least an area of reduced radius with respect to the axis of rotation educated.
  • the length of the thick spots themselves can be the same or to be repetitive in a cycle. But is also common for a uniform appearance of a fabric a different one, especially a randomly different one Thickness length desired.
  • the present invention is accordingly based on the object a random distribution of thick spots in a simple way in a filament yarn both in terms of their mutual Distance as well as their length in the first place or - if already available - to increase.
  • This object is achieved according to one embodiment of the invention solved in that in a second stretching field Increase the randomness of already given random distance and length distributions of the thick spots by temporarily A section by section of heat on the filament yarn or completely stretching out those thick spots, to which the influence of heat happens to be caused.
  • Another task solution provides that in one second stretching field to achieve a randomness in the distance and length distributions of regular distance and length-wise thick spots due to temporary exposure to Heat the filament yarn at least in sections Stretch out those thick spots on which the heat is applied accidentally hits, is effected.
  • a regular distribution of the thick spots is, for example achieved when the thick spots by means of a heat source are generated in which the on the filament yarn effective heating surface of a heating element as a circumference at least a disk driven via an axis of rotation with at least an area of reduced radius with respect to the axis of rotation is trained.
  • the thick places always have the same mutual distance along the filament and same Length.
  • the heat can on the filament also by changing the covering the radiation from a heat radiator on the filament and turned off.
  • An irregular but periodic distribution of the thick spots or the effect of heat for example achieved when the aforementioned disk serving as a heat source several areas reduced radius different Distance and / or different length on the circumference having.
  • the distribution of the thick spots or the effect of heat then leads to a repeat, which occurs with every revolution repeated.
  • the sequences of the thick spots have to pass and exposure to heat when the patterns of the repeats agree, differ from each other. If the patterns differ from each other deviations, randomness is achieved in any case. There is also the option of changing the Speeds of the aforementioned cam disks the randomness further increase.
  • the method according to the invention generally results in a Reduction of the number of thick spots and their length. If in this connection the number and length of the thick spots should not fall below a lower limit, it must original number and length can be chosen accordingly high.
  • a device for producing thick spots 20 in a filament yarn 1 (FIG. 2) a pair of rollers 2 with a downstream godet 3. Between the Roll pair 2 and the godet 3 is a first stretching field I. In this first stretching field, as shown in FIG. 2, by incomplete stretching of the not fully oriented, tapering filament yarn randomly in terms of distance and length distributed thick spots 20 generated in the filament yarn 1.
  • the first stretching field I is followed by a second stretching field II, which is between the godet 3 and a subsequent one Galette 4 lies.
  • This second stretching field II is located a heat source 6, for example in the form of a Axis driven disc with at least one area 6.1 reduced radius with respect to the axis of rotation (FIG. 5, Fig. 6), wherein the heating surface acting on the filament yarn the scope of this disc is.
  • the first stretching field I between the pair of rollers 2 and Galette 3 thick spots 20 distributed along the filament yarn 1 can be generated.
  • the second stretching field is II provided in which the filament yarn 1 with the thick spots 20 is further stretchable, one in the second stretching field II Heat source 6 for temporary exposure to heat on the filament yarn is provided.
  • FIG. 7 shows another possible embodiment of the invention with an optional entry field I.1 with only a slight delay in tension between a pair of rollers 2.1 and a godet 3.1.
  • the first stretching field I is between this godet 3.1 and a subsequent godet 4.1 defines in which the Thick areas 20 according to FIG. 2 are generated. This is done by that the incoming, not fully oriented filament yarn the heat source designed as a rotating hot disk 6 'touched and fully stretched.
  • the disc points however, as described above and shown in Figs. 5 and 6, Areas of reduced diameter 6.1 on the Filament not to be touched. Not in this area warmed filament remains unstretched and forms a thick spot.
  • the resulting thick spots are always the same Distance and equal length. Even if the disc has multiple areas reduced diameter 6.1 different length and possibly also has a different mutual distance, the arrangement and length of the thick spots are repeated with every rotation of the disc.
  • FIG 8 shows another possible embodiment of the invention, in which between the stretching field I and the stretching field II Intermediate field Z is arranged, in which a weak tension delay can rule.
  • This intermediate field Z is defined between a pair of rollers 30 with a flattened roller 30.1 and the godet 3.1. If the flattening of the roller 30.1 in the Clamping line, there is the effect that the separation between the stretching field I and the intermediate field and there is a single stretching field with a common stretching ratio. Accordingly, the flattened roller results 30.1 of the pair of rollers 30 due to the flattening in the nip line a uniform stretching field of larger width, which from the stretching field I and the intermediate field Z is formed and in which Thick places are generated. Stretching these thick spots in stretching area II remains unaffected.
  • FIG. 9 is a very simplified, schematic example illustrates the effect of heat on the Has thick points of a filament yarn.
  • the starting point is a filament yarn according to FIG. 9a with regularly distributed Thickening of length l at a mutual distance i.
  • this filament acts at intervals I in each case a heat source for the duration L.
  • Thick areas that are only part of their length in the area of influence the heat source are only on this Part of the area stretched out, like this at the slightly below the Thicknesses in the middle of the display is the case.
  • the distribution (length, duration, interval and distance) of the elements (thick spots, heating) of the two components (thick / thin yarn, heat) on the the respective application and the desired appearance of the product (e.g. yarn or Area product, i.e. Woven / knitted / knitted) is.
  • fabrics with pimpled thickenings can be used or with stronger or weaker linen or Wild silk character with the help of the device according to the invention or the corresponding method can be achieved.
  • Corresponding the parameters of the individual components must be varied will.
