Definitions

  • the fancy yarn of the above-mentioned patentsCN 1336453, US-A-069446 and GB-A-25367 have an enhanced chromatic contrast because during the drafting step the effect fibres are joined and are combined completely with the base fibres.
  • this fancy yarn has some features that can be enhanced.
  • WO-A-2008/068294 discloses a device and method for producing fancy yarn on a ring spinning machine having at least two support yarns which are twisted together and fibers of a roving which are introduced by means of a drafting device.
  • a support yarn guide feeds in at least two support yarns which are at a distance from one another, in the region of a pair of rollers which are disposed in front of a spinning triangle.
  • fragment of a bundle of effect fibres is meant a stretch of a bundle of fibres for adding effect that has a substantially uniform linear mass of fibres.
  • step c) said injection speed of the bundle of base fibres is accelerated a preset time according to the desired length of the slubby, and a preset value according to the desired thickness of the slubby.
  • the length and the thickness of the slubby can be controlled by a program that determines the acceleration value and time that is applied. Furthermore, it must be pointed out that the control of the length and thickness of the slubby involves itself a control of the length and thickness of the additions of effect fibres in the resulting yarn.
  • the additions of the effect fibres to the yarn of the present invention are formed from fragments of a bundle of fibres, so that they present a more uniform and compact aspect that considerably enhances the effect of the added fibres, and also the final quality of the obtained yarn.
  • Fig. 3 shows a perspective view of the drafting train of Fig. 2.
  • Fig. 4 is an upper perspective view of the drafting train of Fig. 2 in which the upper rollers from the third line of rollers have been removed to see the detail of the floating wedge condenser.
  • Just one bundle 3 of base fibres extends through said three pairs of rollers 2a, 2b, 2c, and for each spinning position, which, when is subjected to increasing rotation speeds of said rollers 2a, 2b, 2c, produces a drafting of said bundle 3 so that its linear mass is decreased until a preset limit for forming a simple yarn with a determined thickness is reached.
  • the fibres already drafted from the bundle 3 enter in a torsion spindle (not shown).
  • each pair of rollers 2a, 2b, 2c are configured by cylinders that are mounted on trestles 4 that also support a bar 5 on which pressure arms 6 are mounted (one arm 6 for each two spinning positions). These pressure arms 6 have the function of placing and holding applying pressure the upper rollers of the three lines of rollers (the rear one 2a, the intermediate one 2b and the frontal one 2c) on their respective lower rollers.
  • the first pair 2a of rollers which constitute what in the present specification has been identified as means for injecting a bundle 10 of effect fibres, is driven by a servomotor through a processing and control unit that is programmed to inject intermittently the bundle 10 of effect fibres to the bundle 3 of base fibres.
  • This injection of the effect fibres is done during the continuous injection of said bundle 3 of base fibres through the second pair 2b of rollers that is driven by a second servomotor associated with the same processing and control unit.
  • the bundle 10 of effect fibres is added to the bundle 3 of base fibres through a first condenser element 11 configured as a funnel that is placed between the first pair 2a of rollers and the second pair 2b of rollers.
  • the strip 14 has the advantage that, on one hand, prevents the vertical movement of the banister 13 and, on the other hand, acts as a spring permitting the horizontal movement of the banister 13 and prevents the overcharge of the engine through which said banister 13 is driven.
  • the horizontal movement of the banister 13, and with it the first condenser 11, is necessary to prevent the premature wear of the upper rollers 2b, 2c produced by the passage of the fibres.
  • the ends of the same rod 15 hold each one condenser 12, so that the same rod 15 can be used for two spinning positions.
  • the process is started, at each spinning position, in the moment that the first pair 2a of rollers is started driven by an independent servomotor for injecting an intermittent stretch of bundle 10 of effect fibres in the bundle 3 of base fibres that is being injected by the second pair 2b of rollers.
  • This injection moment of the effect fibres is ordered by the processing and control unit through a "random" system that takes into account the maximum and minimum separation lengths between fibre additions to prevent the production of what is known as "moiree" or geometric repetition.
  • the slubby makes easier the control of the length and thickness of the additions of the effect fibres, and improves the effect of said fibres.

Abstract

L'invention concerne un procédé de filature de fils fantaisie (16), comportant les étapes consistant à : a) injecter en continu un faisceau (3) de fibres de base dans un train (1) d'étirage ; b) lorsque ledit faisceau (3) de fibres de base est injecté en continu, injecter par intermittence un faisceau (10) de fibres d'effet dans le même train (1) d'étirage pour ajouter par intermittence ledit faisceau (10) de fibres d'effet audit faisceau (3) de fibres de base et, l'injection de l'étape b) étant suivie de : c) l'accélération de la vitesse d'injection du faisceau (3) de fibres de base pour produire un renflement (17) sur ledit faisceau (3) de fibres de base, ladite accélération étant réalisée au moment où un fragment du faisceau (10) de fibres d'effet est ajouté aux fibres de base, le lieu d'injection dudit fragment correspondant audit renflement (17). Le fil fantaisie (16) fabriqué par le procédé comporte une pluralité de renflements (17) dudit faisceau (3) de fibres de base, chacun desdits renflements (17) comprenant un desdits fragments d'un faisceau (10) de fibres d'effet correspondant à une surépaisseur de fibres de base, ladite surépaisseur étant obtenue par la réduction ponctuelle du rapport d'étirage du faisceau (3) de fibres de base.
