Definitions

  • This invention relates to apparatus for the treatment the treatment of yarns consisting at least partly of thermoplastic material, and more particularly to a device for cooling yarns which have been plasticized by heat as is sometimes done in the false twist process.
  • my invention contributes a cooling device for use in connection with false twist systems which obviates the foregoing difficulties and disadvantages and provides an improved cooling effect while permitting a cooling zone of minimum size.
  • my invention is directed to a suction or vacuum device for use in connection with a false twist system for texturing textile yarns by temporarily highly twisting the yarn and heat-treating the same while in the highly twisted condition, and which device comprises a hollow body member preferably positioned immediately after the heating device in the direction of movement of the yarn, the body member being connected with a vacuum pump or the like, and the surface of the hollow body being formed with at least one groove in which the advancing yarn may move, and conditioning a number of spaced apertures or holes communicating with the interior of the hollow body.
  • the pressure differential between the interior and exterior of the hollow body will cause the yarn to be held in the groove, and the ambient air to flow towards and into the hollow body through the spaced holes thus to rapidly cool the advancing yarn.
  • the hollow member may assume the shape of a closed tube of almost any desired cross-sectional contour such as circular, oval, polygonal and so forth, with a single groove, or with a number of parallel grooves where it is desired to treat a number of yarns simultaneously; and the grooved surface of the member may be domed or vaulted in contour so that the yarn follows a similar path, such an arrangement providing optimum yarn control under certain conditions.
  • FIG. 1 is a schematic representation of a false twist system embodying a cooling device according to the present invention
  • FIG. 2 illustrates in vertical crosssection one form of a device in accordance with the present invention
  • FIG. 3 is a cross-sectional view taken along the lines 3-3 of FIG. 2;
  • FIG. 4 is a cross-sectional. view of another form of device according to my invention.
  • FIG. 1 there is shown a false twist system wherein a multi-filarnent textile yarnZ of the type described is taken from a spool t and advanced between a pair of delivery rollers 3 into a heating device 4 in which the yarn is plasticized by contact with hot air or with a heated surface. Thereafter, the yarn 2 advances through a cooling device 5 wherein it is cooled and re-solidified. The yarn then advances through a false twist device 6 which imparts a length of twist in the yarn running back through the cooling device 5 and the heating device 4. Finally, the yarn passes between a second pair of rollers '7, and is then fed to a winding or take-up device (not shown).
  • FIGS. 2 and 3 I have shown the cooling or suction device, comprising a tubular member 8 closed at both ends and rectangular in cross-section according to the illustrated embodiment.
  • the upper or top wall is formed with a semi-circular groove 10 extending centrally and longitudinally in the wall; and a pluraltiy of spaced apertures or holes 11 extend from the base of the groove 10 through the wall 9 and open into the interior of the member 8.
  • the holes 11 be of a diameter of the order of 2.5 mm. and that they be regularly spaced approximately 0.5 cm.
  • the bottom wall 12 is formed centrally with a nozzle or outlet 13 depending from the wall 12 and by means of which a vacuum device (not shown) may be connected with the member 11 to create a vacuum of about between 20 to mm.
  • the advancing yarn is positioned in the groove so as to overlie the several holes 11, and a vacuum is applied through the nozzle 13 to the interior of the member 3.
  • atmospheric air or conditioned air if such is deemed necessary, is drawn from the exterior of the member 8 through the holes 11 so as to move past the yarn 2 and the adjacent surfaces of the groove 10.
  • the hot layer of air surrounding the yarn, and which is dragged along with the yarn from the heating device is separated from the yarn and drawn into the interior of the member 8.
  • the yarn is brought into direct contact with cooling air which is drawn past it and through the holes 11.
  • the surfaces of the groove 10 and holes 11, are also cooled by the moving air so that the yarn, which is held in the groove 10 by the action of the vacuum and advanced along in the direct contact with its surface is contact cooled thus further lowering its temperature.
  • a further advantageous result of the present invention resides in the fact that the vapors of sizing agents and other preparations with which the yarns may have been pre-treated are drawn from the yarn and through the member 8 thus to obviate soiling of the false twist device 6, the rollers '7, or the take-up equipment or subsequent yarn treating apparatus as well as the atmosphere and other machinery in the room. Additionally, it is known that the false twist process tends to cause yarns to balloon around their own axes as they advance through the cooling zone, and that this ballooning can produce undesirable effects in the quality of the textured yarn; but the cooling device herein described obviates ballooning in the cooling zone because the yarn is held firmly in the groove 10 by the pressure differential between the interior and exterior of the member 8.
  • FIG. 4 illustrates a tubular body with a domed top wall 9 and curved groove 10 which is advantageous where additional yarn control is deemed necessary.
  • the device of the present invention is suitable for use in connection with the usual texturing systems containing a false twist device such as a spindle
  • a false twist device such as a spindle
  • the present apparatus also finds application in false twist systems utilizing temporary mutual ply-twisting of several yarns without a false twist imparter such as a spindle, as described in application 4 Ser. No. 331,568, filed Dec. 18, 1963, now US. Patent No. 3,261,155; application Ser. No. 377,845, filed June 25, 1954, now US. Patent No. 3,261,166; and application Ser. No. 377,911, filed June 25, 1964, now US. No. 3,261,156.
  • yarn cooling means for use in connection with false twist systems whereby the length of the cooling zone may be reduced to a minimum while at the same time effective cooling is achieved and vapors of yarn treating agents are drawn from the yarn to a suitable exhaust facility.
  • a hollow member positioned subsequent to the heater in the direction of movement of the yarn, a surface of said member having at least one groove therein for receiving the advancing yarn, means defining a plurality of spaced holes opening at one end in said groove and at the outer end in the interior of said hollow member and said member having means for connecting the interior thereof with a vacuum producing device whereby a pressure differential is established between the interior and exterior of said member to draw air through said holes.
  • Apparatus according to claim 1 further characterized in that a plurality of parallel grooves are provided in said surface each to accommodate a yarn, and Wherein means are provided defining a plurality of spaced holes opening at one end in said grooves and at the other end in the interior of said hollow body.
  • Apparatus according to claim 1 further characterized in that said hollow member is an elongated closed tube.
  • Apparatus according to claim 1 further characterized in that said surface having at least one groove therein is domed in contour.
  • Apparatus according to claim 1 further characterized in that means are provided adjacent said grooved surface to deliver conditioned air to said holes.
