Definitions

  • the present invention relates to an improved process of preparing and dyeing a soft package of a relatively inelastic textured continuous multifilament or spun synthetic polymeric yarn which shrinks substantially under the heating conditions encountered following texturing.
  • a process for texturing continuous filament yarn or staple yarn by means of a turbulent air jet is known from Breen. U.S. Pat. No. 2.852.906.
  • the turbulent jet forms each filament occasionally into a loop and entangles the filaments to bind the loops into a yarn structure consisting of a more or less compact entangled core. crunodal filament loops extending out from the surface of the core and some filament loops buried within the core structure.
  • the yarn is fed into the texturing jet at a rate greater than the take-away speed to provide the excess filament length required for forming loops and a high degree of entanglement.
  • the textured yarn After the textured yarn is taken away from the jet at low tension. it must be stretched tostabiiiie the structure. Otherwise. the yarn will stretch when it is woven or knitted at tensions higher than exist in the jet portion of the texturing process and will usually do so nonuniformly because of nonuniform cyclical tensions in weaving and knitting operations. resulting in irregular fabric appearance. Therefore. it is necessary to apply a tension to the yarn greater than that which the yarn will receive in subsequent winding and fabric making operations. Normally. this is done by winding the yarn on a package at sufficient tension tostabilize the yarn and to provide a firm or hard package of minimum volume which can be handled and shipped without damage. However.
  • Such hard packages are not suitable for package dyeing because they are so tightly wound that it is difficult for liquid dye to uniformly penetrate the package.
  • a soft package of yarn on the other hand. is easily penetrated with liquid dye and is desired for package dyeing of yarn. This has normally been accomplished in the past by rewinding the yarn onto a collapsible core under low winding tension to form a soft package. This additional step of rewinding is costly and time consuming.
  • the soft yarn packages are placed in a dye bath and dyed. They are normally stacked in axial alignment on a dye tank loading rod and compressed axially to eliminate spaces between the ends of adjacent yarn packages. Dye is then circulated through the dye tank loading rods which are normally perforated tubes of smaller diameter than the inside diameter of the yarn packages and the dye temperature is raised at a controlled rate.
  • a typical dye heat cycle for a yarn which has previously been autoclaved. heats the bath from 60 to 110C. at a rate of 4C. per minute and from to IC. at a rate of 2C. per minute.
  • the critical dyeing temperature for such yarn is "0 to l30C.
  • the yarn After dyeing. the yarn is rewound onto a cone to provide a finished package of textured and dyed yarn. During winding. the yarn is lubricated to improve its knitting properties.
  • the stretching may advantageously be performed by progressing the yarn from the smaller step of a stepped roll which controls the take-away speed of the yarn from the texturing jet and progressing it to larger diameter step ofa diameter'greater by 5 to 20 percent than the smaller diameter, the yarn being progressed from one step to another by the use of guides or freely rotating separator rolls.
  • the degree of stretch may advantageously be performed by progressing the yarn from the smaller step of a stepped roll which controls the take-away speed of the yarn from the texturing jet and progressing it to larger diameter step ofa diameter'greater by 5 to 20 percent than the smaller diameter, the yarn being progressed from one step to another by the use of guides or freely rotating separator rolls.
  • the degree of stretch may advantageously be performed by progressing the yarn from the smaller step of a stepped roll which controls the take-away speed of the yarn from the texturing jet and progressing it to larger diameter step ofa diameter'greater by 5 to 20 percent than the smaller diameter, the yarn being progressed from one step to another by the use of guides or
  • the overfeed minus the stretch is preferably at least 10% but is dependent on the material used or the degree of texture desired.
  • the degree of stretch may exceed the overfeed while retaining bulk-giving loops.
  • FIG. 4 is a perspective view of a dye loading rod of FIG. 3.
  • FIG. 5 is an end view of the dye loading rod of FIG. 4- l DETAILED DESCRIPTION OF THE-PREFERRED EMBODIMENT
  • yarn 4 is taken from feed yarn package 2 mounted on platform 3 and passes through tension and stop motion device 5 to feed roll 6 where it may be wrapped several times with the aid of guide 7 to prevent slippage. It then passes to texturing jet 10 which is supplied with compressed air through pipe 8 from a source not shown.
  • texturing jet 10 which is supplied with compressed air through pipe 8 from a source not shown.
  • the yarn may pass through a tank 9 where water or other treating liquid is applied to the yarn before entering texturing jet 10. It may be preferable to place an enclosure around bath 9 and jet T0 to collect droplets of liquid which escape from or are blown off the yarn.
  • the textured yarn then contacts driven roll surface 24 operating at surface speed less than that of feed roll 6.
  • the yarn then passes to another roll surface 25 operating at a surface speed faster than roll surface 24.
  • Roll surfaces 24 and 25 may be the smaller and larger diameter steps on a single driven stepped roll I7. Multiple wraps to reduce slippage may be provided by grooved guides I5 and 16 or equivalent means.
  • the yarn then passes over one or more guides 18 to traverse guide I9 which winds the yarn as soft package 21 on core 20. which is preferably a commercially-available dye spring. collapsible both axially and radially.
  • Core 20 is mounted on a chuck (not shown) which holds core 20 at or near its maximum diameter while package 21 is being wound. Yarn is wound at a tension considerably lower than that encountered during the stretching operation following texturing.
  • FIG. 2 shows details of a preferred texturing device.
  • Texturing jet I0 may preferably be a device of Lubach.
  • U.S. Pat. No. 3,545,057 in which compressed air flowing into the device through pipe 8 encounters a severe restriction of such as hole 13 which directs a concentrated stream of high velocity fluid onto yarn 4 as it emerges from yarn guiding outlet 1!.
  • the turbulent air and the yarn then pass together through the throat of venturi I2.
  • Baffle 14 is free to pivot about hinge pin 23 which is supported by bracket 22 which may be clamped around the periphery of texturing jet I0 and may be adjustable along the length of the jet. Textured yarn leaves jet device I0 at approximately right angles to its direction of travel through the jet. Use of this preferred texturing device not only allows satisfactory texturing at higher speed than prior devices but produces unusually uniform tension in the yarn between the texturing jet and roll I7 which in turn allows more uniform stretching before winding.
  • FIG. 3 shows equipment suitable for dyeing the soft packages.
  • Yarn packages indicated by 27 and 28 are stacked axially on dye loading rod 29 shown in greater detail in FIGS. 4 and 5.
  • the stack of packages is then compressed axially so that the ends of the dye springs compress axially and allow the edges of adjacent packages to contact each other so as to form a uniform column of softly packed yarn.
  • the rods are in a conventional yarn dye tank 26.
  • the lid of dye tank 26 is then closed and dye is pumped from reservoir 30 through conduit 31.
  • Pump 32 forces dye from reservoir 30 through conduits 31 and 33 into dye tank 26, and thence into conduit 34 having vertical pipes which connect with the center of packages 27 and 28.
  • Dye is usually at some elevated temperature such as 60C. when it is first introduced into the dye tank 26.
  • FIGS. 4 and 5 show a preferred dye loading rod in greater detail.
  • Conventional dye equipment generally employs a perforated tube having an outer diameter slightly smaller than the minimum inner diameter of a fully shrunk yarn package.
  • the packages may be misaligned with each other by an amount equal to the difference between the inner diameter of the unshrunk package and the outer diameter of the dye rod.
  • Such misalignment causes uneven compression of yarn at both the inside and outside of packages and results in uneven dyeing.
  • the preferred rod of FIGS. 4 and 5 consists of a longitudinally extending main member 38 having a cross section in the shape of a cross intersecting at angles and having arms of equal length.
  • the point of intersection 39 is the longitudinal axis of the rod.
  • De pendent from member 38 are at least two longitudinally extending members 40 and 41 that are shown in the shape of a round bar supported on springs 42 which extend in a radial direction from the longitudinal axis 39 of the rod.
  • the distance between the longitudinal axis 39 of the main member and the outermost point of either rod 40 or 41 at full extension the distance between the longitudinal axis 39 of the main member and the outermost point of either rod 40 or 41 indicated as L, in the drawings is chosen to coincide with the inside radius of the collapsible core in its initial uncollapsed state. This ensures proper axial alignment of the packages.
  • springs 42 compress.
  • the lengths of the arms of the main members indicated by L; in the drawing should be slightly smaller than the inside radius of a core after full shrinkage.
  • hard pack and soft pack and their derivatives are of course relative.
  • a hard packed core of yarn is so tightly wound that it is difficult or impractical to penetrate with a liquid dye uniformly.
  • a soft package of yarn. is easily penetrated with liquid dye uniformly.
  • a Shore hardness less than 40 is considered a soft package and a Shore hardness over 40 is considered a hard package.
  • Shore hardness is a measure of package density as measured with a Durometer, an in strument for testing package density, manufactured by the Shore Instrument and Manufacturing Company, Inc.
  • the relative humidity of the room in which winding is performed affects the tension of the yarn as wound on the package, it is important to control the relative humidity of such room within a range of about fi% RH. That is to say, the relative humidity should not vary by more than this amount from time to time during the winding operations, and no winding machine should differ from any other running at the same operating conditions by more than this amount.
  • the finished yarn package has a Shore hardness of 24 2 2 with a density of 240 grams per liter.
  • the denier of the yarn as wound on the package is approximately 180 (200 d-tex).
  • Yarn packages are then stacked axially in a dye device and are exposed to liquid dye which is heated from 60to 110C. at a rate of 1C. per minute and from 110 to 130C. at a rate of 2C. per minute.
  • the optimum range for dye pickup for this yarn is 60 to 110C.
  • the denier of the yarn after dyeing is about 200 (220 d-tex).
  • the yarn shrinks about 11% during this process.
  • the dye is held at 150 for at least 30 minutes. then the dye is pumped out of tank 26. the yarn packages are removed from dye rods 28 and are rinsed. Subsequently. the yarn is rewound onto cones and lubricated for knitting or weaving into fabrics. Waste loss during the present process is approximately 2 percent compared to approximately 10 percent for the process of the prior art
  • a continuous process for texturing then winding yarn on a package support that includes the steps of overfeeding a feed yarn through an air texturing jet with the resultant formation of texture-giving loops and winding the textured yarn on the package support under sufficient tension to stabilize the yarn without eliminating the loops and form a package of yarn
  • the improvement comprising: stretching the textured yarn between the texturing and winding steps. the degree of stretch being sufficient to stabilize the yarn without eliminating the loops; and winding the yarn under relatively low constant tension less than about 0.04 gram per denier to form a package of yarn suitable for package dyeing.
