Definitions

  • the invention relates to a method and an apparatus for making fancy yarn from an endless, synthetic filament yarn, which sections different Has thickness and / or orientation.
  • 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 that spanned several Springs is arranged on a holding element. In cooperation with the roll wrapped in filament yarn and the feathers 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 is arranged in the stretching field heat supplying device (DE 196 26 032).
  • This heat supply device can be at least a disc driven via an axis of rotation at least one area of reduced radius with respect to the Axis of rotation be formed.
  • the thick spots remaining in the filament in the aforementioned manner usually have a certain regularity, especially in their arrangement along the filament yarn, i.e. that their mutual distances are equal or in one repeat certain cycle.
  • Thick spot itself can be the same, or repeating itself in a cycle, be trained.
  • the invention is accordingly based on the object to avoid the aforementioned disadvantages, especially simple Way to produce filament yarns, which by different Stretching effects have and largely are resistant to light and aging.
  • the sections different thickness and / or orientation due to incomplete Stretching the not fully oriented filament yarn, by repeatedly interrupting the stretching process or by Increasing resistance to stretching can be generated.
  • a device for producing a fancy yarn from a endless, synthetic filament yarn which sections of different Has thickness and / or orientation a stretching field for generating the aforementioned sections, wherein at least a post-stretching field connects to this stretching field Post-stretching the sections created in the stretching field.
  • the post-stretching field can connect a set zone in which the in the streak field caused orientation of the molecules of the filament yarn under Heat exposure is fixed, so that this orientation for example due to the heat during cooking (or dyeing in warm liquor or warm washing), no more change significantly and not cause the yarn to shrink or the fabric can lead.
  • an endless synthetic filament yarn is passed 1 a pair of rollers 2 with a flattened roller 2.1 and arrives to a stretching field I, which by a subordinate Galette 3 and the pair of rollers 2 is defined.
  • a stretching field I which by a subordinate Galette 3 and the pair of rollers 2 is defined.
  • the stretch ratio is, for example, 1: 1.45.
  • it won't fully stretched sections having filament yarn 1 'one Nachreckfeld II supplied, which by the godet 3 and a godet 4 arranged at a distance therefrom is defined.
  • stretching takes place in a ratio of, for example, 1: 1.10.
  • this post-stretching field the not fully stretched out Sections at least almost fully extended. It follows with it a 1 '' fancy yarn.
  • a godet 20 which is spaced one Galette 30 is preceded.
  • the result is a stretching field I, in which can be a heat supply device 5, which, for example, as at least one over an axis of rotation driven, heated disc with at least one area reduced radius with respect to the axis of rotation is.
  • the Nachreckfeld II is by the godet 30 and a subordinate Galette 40 formed so that even in the device 2 again not fully extended portions of the Filament yarns 1 'are almost fully stretched and one Fancy yarn 1 '' results.
  • the stretching field I becomes a stretching field I.1 upstream, i.e. in front of the godet 20 a galette 20.1.
  • this stretching area I.1 there is an incomplete stretching of the filament yarn 1, for example in a ratio of 1: 1.10.
  • a heat supply Device 5 are.
  • the stretch ratio can be 1: 1.45, for example.
  • the resulting filament yarns have a very high shrinkage on.
  • a set zone III downstream.
  • the heating plate 10 through which is the orientation of the molecules in post-stretching field II the filament yarn is fixed under the influence of heat, so that this orientation changes, for example by the action of heat when boiling or dyeing in warm liquor or warm wash, change only slightly and become oneshrinking of the yarn or fabric.
  • the set ratio can be, for example, 1: 0.9.
  • the Filament yarns produced then have, for example, a shrinkage of about 8 to 3%, an elongation of about 25% and a strength of about 3.6 g / dtex.
  • a hot plate 10 in set zone III one of the two can also set the zone delimiting godets 40 or 40.1 to be heated.
  • FIG. 6 is a length / mass diagram of one in the stretching field I. produced filament yarn 1 'is shown with the thick spots 14, where the abscissa is the length, the ordinate is the mass in cross section of a filament.
  • the thick spots are through an increase in mass by the measure h above its mean and characterized by a length b. Define these thick spots the not fully stretched sections of the filament yarn 1'.
  • Fig. 7 shows a length / mass diagram of the after-stretching field II drawn filament yarn in which the thick spots 14 in Thin spots 14 'are reversed - since the filament yarn is stretched is, the thin spots 14 'have something on the amount b' extended. Instead of the mass increase h there is now a thin point 14 'with a mass decrease by the dimension n. It results an effect yarn 1 ''.
  • the stretching ratios in the different stretching zones I.1, I and II can be different.
  • the aforementioned stretching ratios refer, for example, to a POY template filament, which, when fully stretched, to achieve a residual stretch of 30% require a total stretching of 1: 1.62 would.
