Definitions

  • the method involves stabilizing a core supported wound package of bulked, continuous filament yarn, at a predetermined bulk level by replacing the core with a core of a predetermined smaller diameter to allow the bulk level of the yarn in the inner portion of the package to increase up to the level of the remaining yarn in the package, compressing the package to obtain more uniform density, and thereafter stabilizing the yarn in a heated liquid.
  • This invention relates to the production of textured or bulked yarns formed-from highly stretchable, continuous filament, heat-settable thermoplastic yarns and more particularly to a method of stabilizing such yarns with heat to obtain a uniform bulk level therein.
  • Textured continuous filament yarns are now extensively used in the textile industry due, at least in part, to their outstanding covering ability, texture and hand, easy care and serviceability, long wear life, etc.
  • the yarn In those processes involving twisting and heat-setting to bulk the yarn, the yarn is quite lively or unbalanced, and highly stretchable after twisting. Thus, it is common to modify or stabilize the yarn at the desired bulk level by subjecting it to an additional heat-setting treatment.
  • the yarn which has a strong tendency to contract due to its highly stretchable nature, begins to contract (and therefore gain bulk) after it is wound into package form, and while the yarn in the outer portion of the package can so contract a calculatable amount inwardly of the package, the yarn in Patented Feb. 4, 1969 the inner portion of the package does not have the same amount of freedom due to the presence of the winding core.
  • the yarn in the inner portion of the package will have a lower bulk level than the yarn in the outer portion, often as much as 8 to 10% lower, depending upon the particular yarn.
  • Another method involves winding the unstabilized yarn onto a take-up bobbin without overfeeding (and thus without bulk) and then removing the bobbin whereupon the yarn is then wholly free to contract inwardly toward the center of the package and bulk to a given bulk level. The thus bulked yarn is then stabilized at such given bulk level.
  • a considerable drawback to this method is that all of the bulk must be developed after the yarn is wound into package form, and thus, uniformity and control of bulk level within packages and from package to package is most diflicult to obtain.
  • this new method involves the modification of a package of bulked, highly stretchable yarn wherein the bulk of the yarn in the outer portion of the package is at substantially the desired bulk level by replacing the winding core thereof with a perforate core of a predetermined smaller diameter to permit the bulk level of the yarn in the inner portion of the package to increase to the desired bulk level of the other yarn and give such yarn more room to shrink during stabilization.
  • the thusly modified package is then compressed to break-up the yarn and obtain a more uniform density, whereupon it is then stabilized by forcing a heated liquid through the package, as for example, by treating it in a yarn package dyeing machine.
  • FIGURE 1 is a schematic illustration of a yarn falsetwisting operation
  • FIGURE 2 is an isometric view of an apparatus suitable for replacing and inserting cores of and into yarn packages and for compressing such packages;
  • FIGURE 3 is an enlarged fragmentary side elevation of the core replacing elements and comprising the apparatus shown in FIGURE 2;
  • FIGURE 4 is similar to FIGURE 3 and additionally shows a yarn package positioned for replacement of its core;
  • FIGURE 5 is a still further enlarged fragmentary vertical sectional view of a yarn package as in FIGURE 4 during replacement of the winding core thereof;
  • FIGURE 6 is similar to FIGURE 4 and shows the yarn package after replacement of the core and during compression.
  • FIGURE 1 there is represented a schematic illustration of a conventional false-twisting operation for bulking a continuous filament thermoplastic yarn such as polyester, nylon or cellulose triacetate.
  • a yarn is typically bulked by being led from the supply package 10, through suitable holding means 11, heating means 12, a false-twist spindle 13, another holding means 14, and finally, onto a take-up package 15 wound on a core 16, such as a cardboard tube.
  • a core 16 such as a cardboard tube.
  • the bulk level of the yarn within such a take-up package tends to vary as much as 8 to 10% from the inside to the outside of the package due to the fact that the yarn in the inner portion of the package is prevented from contracting by the winding core 16.
  • a package of such yarn is formed so that the bulk level of the yarn in the outer portion is at that level which is ultimately desired, and the bulk level of the yarn in the inner portion of the package is below such level.
  • sock 17 or the like, as shown in the figures.
  • Such sock usually takes the form of a knitted tube which covers and is stored with the winding core 16 before winding and which has sufficient length and stretchability to fit around the package after winding.
  • the core replacing operation should be accomplished by simultaneously inserting the perforate core while removing the winding core, as by pushing one with the other. Otherwise, the package 15 will close inwardly too much and the bulk level of the yarn toward the center of the package will increase to a level greater than that of the yarn toward the outside.
  • the perforate replacement core be of a diameter just enough smaller than the diameter of the winding core 16 to permit just enough inward expansion of the package to achieve the desired uniform bulk level.
  • This difference in diameter will vary with different types and deniers of thermoplastic yarns. For example, in the case of polyester yarns in the range of 70 to 200 denier, the difference in diameters should be within the range of about .240 to .500 inch.
  • the replacement core is perforate, such as a foraminous stainless steel dye tube or dye spring, in order to permit free flow of liquid therethrough and through the package during the stabilizing treatment.
  • FIGURES 2-6 For removing the winding core 16 from the package 15, I provide an apparatus such as that shown in FIGURES 2-6 which comprises a vertically movable mandrel 20, and upon actuation of the air cylinder 21, 21 mounted thereabove.
  • a flange 22 is provided on the upper end of the mandrel for reasons which will become apparent hereinafter.
  • a platform 23 is provided below the mandrel for supporting a yarn package to be cored, such platform having an opening 24 therein to permit passage of the expelled winding core 16 through the platform and to a collection point (not shown).
  • the package 15 is centered on the platform 23 so that the core 16 is positioned directly over the opening 24.
  • a perforate tube 25 is then placed on the mandrel 20, and upon actuation of the air cylinder 21, the perforate tube 25 is engaged by the flange 22 and pushed downwardly into engagement with tube 16, whereupon continued downward movement causes the tube 25 to push the tube 16 completely out of the package.
  • a compressing of the package may be carried out during the core replacement operation as shown, for example, in FIGURE 6 wherein continued downward movement of the mandrel 20 after insertion of the tube 25 brings the flange 22 into axial compressing engagement with the package 15.
  • the thusly modified package After replacing the core 16 with the core 25 and compressing the package as heretofore described, the thusly modified package has a uniform bulk level throughout and is in condition for stabilization.
  • wet-setting that is, setting with a liquid such as water, rather than steam-setting the yarn.
  • wet-setting that is, setting with a liquid such as water
  • a 200 denier continuous filament polyester yarn is bulked on a false-twist machine by inserting 56 turns per inch through the heating zone with the heater block being maintained at 195 C., with the yarn being overfed 1% in the heating zone to allow for shrinkage, and with the take-up package being run at a speed 10% slower than the yarn supply speed to allow the yarn to bulk to a predetermined level.
  • a package of bulked yarn is thus formed weighing approximately 1.3 lbs. and being supported on a paper takeup tube having an outside diameter of 1.905 inches (1% inches ID. and .140 inch wall thickness).
  • the package is then placed in any suitable apparatus where the tube or core is pushed out with and replaced by a stainless steel perforate dye tube having an outside diameter of 1.645 inches (1% inches LD. and .010 inch wall thickness) and the package is then compressed by applying an axial compressive force thereto.
  • the thus compressed and modified package which now has a uniform bulk level throughout, is then placed along with other similar packages in a package dyeing machine where the yarn is then stabilized by pumping water at 250-260 F. through the packages for 30-40 minutes.
  • the yarn packages are then pressure extracted and dried in a conventional manner.
  • a 150 denier continuous filament polyester yarn is bulked in a manner similar to that described in Example I except that turns per inch of twist and 16% overfeed onto the take-up package are used.
  • the yarn is taken up onto a paper tube having an outside diameter of 1.875 inches (1% inches ID. and .125 inch wall thickness).
  • the package is then modified in the same way as in Example I by replacing the core with a stainless steel perforate dye tube having an outside diameter of 1.645 inches (l /s inches ID. and .010 inch wall thickness) and compressed by applying an axial compressive force thereto.
  • the package is then placed along with other similar packages in a yarn package dyeing machine and dyed with the temperature of the dyebath being held at 250- 260 F. for at least 30 minutes.
  • the dyed and stabilized yarn packages are then pressure extracted and dried in a conventional manner.
  • a method according to claim 1 wherein the yarn is a polyester yarn in which the bulk and high stretchability has been imparted thereto by twisting, heat-setting and untwisting in a continuous operation.
  • a method according to claim 4 in which a dyestuif is present in the aqueous lbath for dyeing the yarn during stabilization thereof.
