Definitions

  • the present invention relates to the production of thermoplastic textile yarn. More particularly, the present invention relates to a method of processing thermoplastic textile yarn of Varying denier to produce yarn exhibiting intermittent texture, as well as to such yarn.
  • Textured yarn In order to impart certain desirable properties to continuous man-made filament yarn it is common practice to texture or loft same. Textured yarn possesses greater bulkiness, better heat insulating power and other improved properties while still retaining many of the desirable characteristics of spun yarn.
  • One method of considerable commercial significance for producing textured yarn involves the steps of hot drawing substantially undrawn thermoplastic continuous filament yarn and immediately thereafter simultaneously cooling and deforming the yarn by passing same between a pair of intermeshing gears.
  • the thus-textured yarn has greater bulk which is more fully developed by a subsequent heat treatment while the yarn is under low tension.
  • twist-curled textured yarn is made by a three step process.
  • the yarn is twisted a desired amount.
  • the yarn is heat-set during the second step. That is, the yarn is heated and cooled while twisted so as to render the yarn dimensionally stable until again heated to or above the setting temperature.
  • the twist imparted and set in the yarn can be a true twist or a false twist. For economic reasons, the latter twist is preferred.
  • False twisting is a well-known method by which a yarn is twisted and untwisted in one operation, the yarn being heat-set when twisted.
  • a third method of considerable commercial importance utilizes the well known stuffing box technique to induce substantially permanent crimp in the yarn.
  • the yarn is characterized by sharp elbows between the arms of the crimps induced therein.
  • thermoplastic continuous filaments thermoplastic continuous filaments.
  • intermittent texture by periodically interrupting the intermeshing of the gears in the above-mentioned gear crimping procedure.
  • Another object is to provide a method of producing intermittently twist-curled continuous filament yarn.
  • Another object is to provide a method of producing intermittently stufiing box crimped continuous filament yarn.
  • a novel method of producing intermittently textured yarn wherein the lofted portions thereof are periodic or random A source of thermoplastic man-made continuous filament yarn is provided. The yarn is drawn below the natural draw ratio so that the yarn exhibits thick and thin portions along the lengt-h thereof. The yarn is subjected to a texturing or lofting operation after which the yarn is stretched to complete the natural draw thereof.
  • the under drawn yarn having the thick and thin portions is forwarded longitudinally through a zone wherein the yarn is heated to render same more amenable to being textured.
  • the thus-heated yarn is simultaneously cooled and deformed.
  • the cooling and deformation are accomplished by passing the yarn between intermeshing toothed wheels.
  • the gears will stretch the yarn a minor amount, the yarn ordinarily is stretchedin a separate operation to complete the natural draw thereof.
  • the thin portions of the yarn are textured presenting a crimpy appearance; and the thick portions of the yarn are thereby lastingly stretched presenting a substantially uncrimped appearance.
  • the uncrimped sections When the yarn is dyed before having the stretch removed therefrom, the uncrimped sections will imbibe considerably more dye and, therefore, will exhibit a more deeply or darker dyed appearance than the crimped sections.
  • the resulting intermittently textured yarn can be used to construct fabric having novelty effects and desirable properties.
  • yarn drawn below the natural draw ratio so that it exhibits thick and thin portions along the length thereof is forwarded longitudinally through a zone wherein the yarn is twist-curled by being twisted, heated and cooled while twisted and then is untwisted. Thereafter, the yarn is stretched to complete the draw thereof. The thin portions of the yarn remain twistcurled; and the thick portions of the yarn are thereby lastingly stretched presenting a substantially straight, uncurled appearance. Finally, the yarn is connected in an orderly manner. The resulting intermittently textured yarn can be used to construct fabric having novelty effects and desirable properties. When the yarn is dyed before having the stretch removed therefrom, the uncurled sections exhibit a more deeply or darker dyed appearance than the twist-curled sections.
  • yarn drawn beiow the natural draw ratio so that it exhibits thick and thin portions along the length thereof is forwarded longitudinally through a confined zone wherein the yarn is stuffing box crimped.
  • This is accomplished by cramming the yarn longitudinally through the confined zone in the form of accordion-like folds having the crimp frequency and crimp amplitude of conventional stufiing box crimping.
  • the crainming crumples successive lengths into folds and pushes the yarn in the folded condition through the zone.
  • the yarn is heated and then cooled to set the crimp therein. After being withdrawn from the zone, the yarn is stretched to complete the draw thereof.
  • the thin portions of the yarn remain crimped; and the thick portions of the yarn are thereby lastingly stretched presenting a substantially straight, uncrimped apperance. Finally, the yarn is collected in an orderly manner.
  • the resulting textured yarn can be used to construct fabric having novelty effects and desirable properties. Again, when the yarn is dyed before having the stretch removed therefrom, the
  • uncrimped sections exhibit a more deeply or darker dyed appearance than the crimped sections.
  • the yarn drawn below the natural drawn ratio so that it exhibits thick and thin portions along the length thereof is knitted into a fabric.
  • the resulting fabric is heat-set and then unraveled.
  • the yarn thereafter is stretched to complete the draw thereof.
  • the thin portions of the yarn remain crimped; and the thick portions of the yarn are thereby lastingly stretched presenting a substantially straight, uncrimped appearance.
  • the resulting textured yarn can be used to construct fabric having novelty effects and desirable properties.
  • the uncrimped sections exhibit a more deeply or darker dyed appearance than the crimped sections.
  • yarn drawn below the natural draw ratio so that it exhibits thick and thin portions can be distorted by a hot plasticizing fluid-jet process.
  • a moving threadline is discomposed by a hot uid, such as superheated steam.
  • the process induces crimps in the yarn without crunodal loops being formed therein.
  • the yarn is stretched to complete the draw thereof.
  • the thin portions of the yarn remain crimped; and the thick portions of the yarn are thereby lastingly stretched presenting a substantially straight, uncrimped appearance.
  • the resulting textured yarn can be used to construct fabric having novelty effects and desirable properties.

  • the yarn has not been fully oriented.
  • Nascent man-made ilaments, as a rule, do not show a high order of molecular orientation and have a relatively low load-bearing capacity.
  • To orient the filaments and thereby to increase greatly the strength thereof they are stretched a desired extent, as is well known.
  • the filaments normally are stretched using a natural draw ratio. This results in an extension of the filaments which is sufficient to change them from their undrawn state to a uniformly drawn and highly oriented state without straining them to introduce surface cracks or filament breaks.
  • a draw ratio lower than the natural draw ratio some sections of the filaments will draw at the natural draw ratio while other sections, in the main, will not draw at all.
  • FIGURE l the yarn 1 has been drawn by means of two thread advancing devices operated at a peripheral speed differential predetermined to provide a draw ratio less than the natural draw ratio under the drawing conditions employed.
  • the thin portions 3 exhibit considerably greater' molecular orientation than the thick portions 2.
  • FIGURE 2 intermittently textured fully drawn yarn 4 is shown. It will be noted that the yarn exhibits uncrimped sections 5 and crimped sections 6. Generally, the uncrimped sections 5 correspond to the thick portions 2; and the crimped sections 6 correspond to the thin portions 3. When the yarn has been dyed by conventional yarn dyeing before completion of the natural draw, the yarn is two-toned presenting different shades of the same color. The uncrimped sections possess a different and darker shade from the same color of the crimped sections.

  • the yarn is passed through a pair of feed rolls 7 to supply it at a predetermined delivery speed.
  • the yarn 1 is led through a heated Zone provided by a circumferential heater 8.
  • this heater is a tubular device having an electrical resistant heater element imbedded therein. Obviously other heating devices for suitably raising the temperature of the thick and thin yarn 1 can be used as well.
  • the yarn is directed between rotatably mounted, driven crimping gears 9 and 10 that mesh.
  • the yarn is subjected to laterally applied stresses increasing and decreasing in intensity as the yarn approaches and leaves the horizontal plane in which the axes of the crimping gears lie. While subjected to the action of the teeth, the undrawn or thick portions 2 are sligthly drawn and the drawn or thin portions -are deformed. While being so-drawn and deformed, the yarn is cooled. To provide this cooling which is of importance to obtain the intermittent crimp, gears 9 and 10 can be positively cooled. As illustrated a nozzle 11 is positioned to direct a stream of coolant onto gear 9. Under certain conditions it can be advantageous to pass the yarn through the mesh of the gears a plurality of times. To do this, a separator roll 12 can be positioned adjacent one of the gears.
  • the yarn After being cooled and deformed by the gears, the yarn is ordinarily taken up in an orderly manner. As shown the yarn is wound in the form of a package 13 by a driven spindle 14. However, before take-up or after take-up the yarn is stretched to complete the draw thereof, resulting in removing the variation in denier originally therein. If desired, this stretch can be accomplished by use of a thread advancing means (not shown) in the path of the yarn between the gears and the take-up device. The thread advancing means is operated at a faster ⁇ speed relative to the yarn forwarding speed of the gears to provide the desired stretch along the length thereof. Furthermore, the yarn can be withdrawn from package 13 and forwarded to a second take-up at a faster speed to finish the draw thereof.
