Definitions

  • This invention relates to yarn texturing machines, and in particular to textile machines for the texturing of yarns by means of fluid jets.
  • Textile machines are known in which one or more yarns are fed in single, parallel or core/effect form to a fluid jet in which the turbulent fluid serves to cause the filaments of the yarns to form loops, thereby producing a bulky single or composite yarn suitable for various textile applications.
  • a yarn wetting device may be located immediately upstream of the fluid jet, acting on some or all of the yarns, and in such cases the yarn wetting device and the fluid jet are customarily housed in a common housing or "jet-box".
  • parallel and, more especially,core/effect arrangements in order to ensure acceptable texturing of the yarn, it is necessary that any yarn which runs through the wetting device is kept apart from the other yarn or yarns until they come together in the fluid jet itself.
  • the invention provides a yarn texturing machine comprising a fluid jet texturing means for a plurality of yarns to form a textured yarn and respective feed means for each of said yarns, whereby each of said feed means is disposed in said machine relative to the other feed means and said fluid jet texturing means so as to feed the respective yarn along a substantially straight yarn path from said feed means to said fluid jet texturing means, which yarn path is spaced from the path of the other yarn or yarns but converges therewith within said fluid jet texturing means at an angle of between 70 o and 50 o to each other. Said paths may converge at an angle of substantially 65 o .
  • the plane containing said yarn paths may be inclined to the axis of said jet at an angle of between 60 o and 90 o , preferably at substantially 70 o .
  • Each of said feed means may comprise a pair of feed rollers providing a nip therebetween through which the respective yarn may travel. One roller of each of said pairs of feed rollers may be driven in rotation.
  • said machine may comprise respective first feed means operable to forward said yarn to said respective feed means at a speed less than that at which said yarn is fed to said fluid jet texturing means, whereby said yarn is drawn between said first feed means and said respective,drawing, feed means.
  • Each of said first feed means may comprise a pair of first feed rollers providing a nip therebetween through which the respective yarn may travel. One roller of each of said pairs of first feed rollers may be driven in rotation.
  • Heating means for each of said yarns may be provided between the respective first feed means and the respective drawing feed means, and said heating means may comprise a plate, pin or roller.
  • a common heating means may be provided for said plurality of yarns, and said heating means may be electrical heating means or may be vapour phase heating means.
  • Said machine may comprise a creel, whereby said first feed means are operable to withdraw said yarns form respective supplies thereof mounted in said creel.
  • Said machine may comprise a main frame spaced from said creel and on which said fluid jet texturing means, said drawing feed means and said first feed means are mounted, said first feed means withdrawing said yarns from said supplies thereof along feed paths extending above an operator's aisle disposed between said creel and said main frame.
  • the machine may also comprise yarn wetting means which may be disposed adjacent but upstream of said fluid jet texturing means.
  • Said wetting means may comprise means adapted to apply water to at least one of said yarns, in which case said wetting means may be disposed so as to apply water to a yarn forming a core yarn of said textured yarn.
  • Said machine may comprise wind-up means, which may be mounted in said main frame beneath said fluid jet texturing means. Said feed means and said wind up means may be driven by respective drive shafts extending longitudinally of said machine.
  • Said machine may also comprise further treatment means, such as heating means, which may comprise an elongate contact heater mounted on said main frame above said fluid jet texturing means to extend upwardly therefrom.
  • Said further treatment heating means may also comprise turnround yarn guide means around which said textured yarn may pass between an upwards and a downwards passage over said heating means.
  • Said turnround guide means may be mounted on said further treatment heater to be movable longitudinally thereof between a threading location at the lower end of said further treatment heater and an operating location at the upper end of said further treatment heater.
  • Said turnround guide means may be mounted on a sledge.
  • Said further treatment heating means may comprise a heater plate having a pair of substantially parallel grooves therein extending from said lower end to said upper end of said heater.
  • the texturing section 21 is shown in greater detail in Figs 2 and 3, and comprises a "box" or housing 23 which is mounted on the main frame 11 and in which is mounted a fluid jet 24 such as an air jet.
  • the relative disposition of the drawing feed means 19, 20 and the fluid jet 24 is such that the yarns 15, 16 are fed from the former to the latter along spaced respective, substantially straight paths, which converge with each other within the fluid jet 24, the plane of the yarn paths being inclined to the axis A of the fluid jet 24 at an angle ⁇ of between 60 o and 90 o , preferably substantially 70 o , as shown in Fig 3.
  • the yarn paths converge at an angle ⁇ of between 70 o and 50 o , for example substantially 65 o as shown in Fig 2, thereby ensuring optimum control of the yarns in this low tension region and good quality of textured yarn at completion of texturing.
  • the wetting means 25 is preferably of the type described in British Patent No 2171931 which applies liquid to the core or wetted yarn 15, without it deviating substantially from a straight yarn path from the drawing feed means 20 to the fluid jet 24. In this particular case water from a supply 26 thereof is fed to a manifold 27 and then to the applicator head 28.
  • the wetted yarn 15, and the yarn 16 are fed into the fluid jet 24, to which air or other fluid from a supply 29 thereof is also fed.
  • the yarns 15, 16 are textured and combined to form a single textured yarn 30 which issues from the fluid jet 24 and is guided through a guide 31 upwardly out of the box or housing 23.
  • Third feed means 32 driven by drive shaft 44 forwards the textured yarn 30 from the fluid jet 24 to a further treatment or setting heater 33 which extends upwardly above the texturing section 21.
  • the third feed means 32 also comprises a roller driven by drive shaft 44 and a freely rotatable roller forming a nip therewith through which the yarn 30 may pass.
  • the driven roller of the of the third feed means 32 may be driven so as to have a peripheral speed less than that of the driven rollers of the drawing feed means 19, 20 so that the yarns 15, 16 are overfed into the texturing section 21 if desired.
  • the textured yarn 30 passes around a "turnround" guide 34 mounted on a sledge 35 which is itself mounted on the heater 33 so as to be movable longitudinally thereof between a threading position at the lower end of heater 33 (shown in dashed lines in Fig 2) and an operating position at the upper end of the heater 33 (shown in full lines in Figs 1 and 2).
  • the yarn 30 makes an upward and then a downward passage over the further treatment heater 33, passing in contact therewith along a groove 37 on its upward journey and groove 38 on its downward journey.
  • the grooves 37, 38 are substantially parallel and extend from the lower end of the heater plate 39 of heater 33 to the upper end thereof.
  • the yarn 30 is fed downwardly by fourth feed means 45 to wind up means 36 mounted on the main frame 11 in three rows, one above the other beneath the texturing section 21.
  • the fourth feed means 45 and the wind-up means 36 are driven by respective drive shafts 46, 47 extending longitudinally of the machine 10.
  • wetting means 25 for both yarns may be provided, and the wetting means 25 may be disposed outside of the housing 23 if preferred, the housing 23 being provided around the fluid jet 24 to contain spray issuing therefrom due to the action of the fluid jet on the wet yarn.
  • the textured yarn 30 may be drawn from the housing 23 in a downwards direction to a further treatment heater 33 disposed in the main frame 11 beneath the texturing section 21 and behind the wind-up means 36, although such an arrangement may limit the length of the heater 33 and therefore the amount of further treatment received by the yarn 30.
  • first feed means and drawing feed means for the two yarns 15, 16 enables different draw ratios to be applied to the two yarns and different feed rates to the texturing section 21.
  • separate draw pins or rollers 22 may be provided if desired, particularly if the drawing temperature for the two yarns is to be different.
  • the yarns 15, 16 may pass around differing diameter parts of the same feed roller for the purpose of providing differing feed speeds and/or draw ratios.
  • the relative position of the fluid jet 24 and the drawing feed means 19, 20 may be adjustable so as to vary the angle of convergence of the two yarns 15, 16 if desired.
  • any one or each of the feed means 17, 18, 19, 20, 32, 45 may be replaced by a roller / apron, double apron or capstan feed device if desired, each driven by a respective drive shaft extending longitudinally of the machine and common to the appropriate feed means of all the yarn processing stations.
  • the further treatment heaters 33 for each yarn processing station may be connected as part of a multi-station heater, for example by means of an elongate boiler extending longitudinally of the machine 10 of a vapour phase heater.
  • the jet 24, or at least such yarn contacting parts thereof are of a ceramic material.
  • the use of such a material enables the yarns 15, 16 to enter the jet 24 under tension at the angle of between 60 o and 90 o to the axis A of the jet 24 without undue wear on the entry part of the jet 24.
