Definitions

  • the invention relates to a method and a V orcardi for producing a fancy yarn from a continuous synthetic filament yarn which portions differences d Licher thickness and / or orientation and crystallinity.
  • JP-Hei-6-1 7337 As prior art, it is already known (JP-Hei-6-1 7337), of at least one endless, synthetic thermoplastic filament yarn consisting intentionally randomly d o to provide it regularly distributed thick places.
  • the filament yarn is wrapped around a roll, which is arranged on a holding element via several springs. In cooperation with the roll wrapped in filament yarn and the springs, the filament yarn is given a thick point at certain intervals.
  • Another state of the art is to produce sections with different melting temperatures in man-made fibers in that they are not heated in sections of their length when stretched under the action of heat (DE 38 41 525 AI).
  • stretch rollers with grooves are used, in the area of which the fila duck are not heated.
  • a device for carrying out this method has a stretching field delimited by an input delivery unit and an output delivery unit, with the filament yarn in between is arranged in the stretching field heat-supplying device (DE 196 26 032).
  • This heat-supplying device is designed as at least one disk driven via a turning axis with at least one area with a reduced radius with respect to the axis of rotation.
  • the invention is therefore based on methods for producing filament yarns with sections of different stretching and thus thickness from endless monofilament or multifilament, synthetic filament yarn, in which the aforementioned sections are produced by incomplete stretching of a filament yarn that is not fully oriented.
  • Filament yarns of this type have the disadvantage, however, that the strength in the not fully stretched thick areas or in the aforementioned sections decreases significantly over time, in particular under the influence of light.
  • the present invention has for its object to provide a method and an apparatus with which fancy yarns of the type mentioned are produced, which are resistant to the action of light.
  • Stretching can take place in any known manner according to the state of the art, for example by incomplete stretching a not fully oriented filament yarn by repeatedly interrupting the stretching process or by increasing the resistance to stretching.
  • the texturing of the filament yarn can be carried out, for example, using false twists, upsetting crimping or air-blasting texturing.
  • the texture of the thread sections is removed; as a result, they become smooth thread sections between the textured remaining, thin thread sections stretched out before texturing.
  • the post-stretching which can be carried out at most as stretching up to the natural degree of stretching with the greatest possible orientation, also reduces their susceptibility to the effects of light at least to a substantial extent.
  • a filament is to be produced which has sections which can subsequently be substantially stretched.
  • these sections that can still be stretched out are stretched out as fully as those that were fully stretched out in the first step.
  • the resulting yarn has (essentially) the same amount of substance in cross-section over its entire length.
  • the result is a filament yarn that is fully stretched along its entire length and has textured and smooth, and thus thicker and thinner, sections. It is advantageous that these two types of sections also have different orientations and crystallinity. In particular, the increased crystallinity increases the depth of the effect when staining.
  • an endless, synthetic, partially oriented and not fully stretched filament yarn 1 runs over a grooved thread guide 2 to a delivery roller 3.
  • a pre-stretching field I is then reached, which is present between the delivery roller 3 and a godet 5.
  • a heat-supplying device 4 can be arranged here, which is formed, for example, from a heated disk driven via an axis of rotation with at least one region of reduced radius with respect to the axis of rotation. In this stretching field I, sections 20 of different thickness are produced in the filament yarn 1 by different, alternating stretching.
  • This pre-stretching field I is followed by a texturing field II, in which a fixing heating element 10 and at least one texturing unit 11 are arranged.
  • the filament yarn 1 ′ is textured in this texturing field II, for example by means of the texturing unit 11 designed as a false twist spindle.
  • the texturing field II is defined by the godet 5 and a thread conveying device located at a distance therefrom, which is designed, for example, as a godet 6.
  • This texturing field II is followed by a post-stretching field III, which is formed by a thread conveying device 7, for example a godet, located at a distance from the godet 6. det.
  • a thread conveying device 7 for example a godet
  • this stretching field III the sections 20 which are not fully stretched in the stretching field I are stretched, in particular fully stretched.
  • the texture of these thread sections is removed; they thereby become smooth thread sections 20 'between the textured remaining thin thread sections stretched out before the texturing.
  • the thread sections processed in the post-stretching field are e.g. fixed under the influence of heat.
  • This effect can be significantly increased by dyeing the filament yarn or a fabric made from it (fabric, knitted fabric, knitted fabric). Not only do the textured sections have a completely different color rendering than the smooth sections, but the smooth sections also have a higher crystallinity than the textured sections and accordingly a different dyeability.

Abstract

L'invention concerne un procédé et un dispositif pour fabriquer un fil fantaisie (1'') à partir d'un fil continu synthétique (1) présentant des sections (20) d'épaisseur et/ou d'orientation ou encore de cristallinité différentes. On effectue une texturation du fil continu (1) pourvu desdites sections (20), suivie d'un post-étirage de ces sections (20) du fil continu texturé. A cet effet, une zone de texturation (II) suivie d'une zone de post-étirage (III) est disposée en aval d'une zone de pré-étirage (I).
