Definitions

  • This invention relates to the production of a limited stretch bulked yarn and more particularly to a method and apparatus for producing a yarn composed of one or more continuous synthetic filaments wherein at least some of the filaments are crimped or bulked and others of the filaments are either straight or are less highly bulked.
  • An object is to provide a yarn of the above type having novel and improved characteristics.
  • Another object is to provide a method and apparatus for producing a bulked yarn having limited stretch or non-stretch characteristics such that the yarn retains its bulked state when placed under tension during weaving or knitting.
  • Another object is to provide a yarn of the above type wherein the filaments are bound together by twisting or by a bonding agent in such a way that the less highly bulked yarn controls the stretch characteristics of the yarn and the more highly bulked components retain their bulked efiect.
  • Another object is to provide a yarn of the above type having difierent degrees of bulk along its length.
  • Another object is to provide a method of making such a yarn wherein the amount of bulk is varied at predetermined intervals along the yarn for producing a novelty effect.
  • a further object is to provide a novel and improved method for making a yarn of the above type.
  • FIG. 1 is an elevation of an apparatus for carrying out the present method, with parts in section for clarity;
  • FIG. 2 is a partial elevation of a modified apparatus wherein the core yarn is passed through a waxing station prior to plying;
  • FIG. 3 is a partial elevation, similar to FIG. 2, illustrating an embodiment wherein the core yarn is passed through the heater with the prebulked yarn;
  • FIG. 4 is a similar partial elevation showing an embodiment utilizing a variable speed drive for one of the pairs of rolls.
  • FIG. 5 is a detail view of a yarn embodying the intion.

  • suitable means as in a stutter crimper, false twister, knife edge crimper or air jet and permanently set in bulked state.
  • the yarn When this yarn is wound onto a package the crimps are temporarily pulled out and after standing for a period of time the yarn acquires a temporary straight set which is removed by subsequent heating in relaxed state.
  • the yarn 10 may be in straight form at the bite of the feed rolls 14 and 15, but resumes its bulked form when heated in the heater 17 provided the tension is relaxed sufficiently at this point to permit the crimps to reform.
  • the heater may be omitted as the yarn will resume its crimped form without heating when the tension is relaxed.
  • the heater 17 is shown as comprising a block having a wall 22 adapted to receive a heating element not shown and having a slightly curved surface 23 over which the yarn feeds for heat transfer by conduction.
  • the feed roll 14 may have a rubber or silicone surface and may be mounted on a pivoted arm 27 for movement toward and away from the roll 15.
  • the roll 14 is pressed against the roll 15 by a spring 28 and may be retracted by a solenoid 29 having an armature 30 connected to the pivoted arm 27 by a link 31.

  • the feed rolls Ztl and 21 are driven at a predetermined constant speed and the feed rolls 14 and 15 are driven at a greater speed so as to overfeed the yarn 10 intothe heater 17 whereby the tension on the yarn is relaxed in the heater 17 for permitting the yarn to rebulk as previously indicated.
  • the yarn is pulled directly through the tension means 12 by the lower feed rolls 2d and 21. Tension is thus maintained on the yarn within the heater 17 so that the yarn remains straight as it wipes over the surface 23.
  • the yarn is thus set in straight form so that the crimp is permanently removed from this portion of the yarn.
  • the rolls 14 and 15 may be so positioned that the roll 14 shifts the yarn out of contact with the surfaces 23 when the two rolls are in feeding posit-ion thereby leaving the yarn free to rebulk While in the heating zone.
  • An uncrimped straight filament '37 is taken from a package 38 through a tension means 39 and fed to the bite of the feed rolls 20 and 21 where it is plied with the filament 10.
  • the plied filaments lit and 37 are fed through a guide 411 to the traveler 41 of a ring twister 42 wherein the filaments are twisted into yarn form and are wound onto a spool 43 carried by a spindle 44.
  • the filaments 1t and 37 may be bound together by the twist to form a yarn having a combination of controlled stretch and bulk determined by the bulk of the filament 1d and the stretch characteristics of the filament 37.
  • the friction of the filaments can be increased by treatment with a frictionagent such as fine silica or by a pressure sensitive adhesive bonding agent such as a wax or a thermoplastic compound.
  • the yarn will have limited stretch characteristics. If the fialment 37 is straight the yarn will have non-stretch characteristics. In any event the bulk is maintained while the yarn is under tension.
  • FIG. 2. shows a modification of the apparatus of FIG. 1 wherein wax or other bonding agent is applied to the filament 37a before it is fed to the bite of the rolls 2th and 21.
  • the filament 37a is fed from a package 38a through a tension means 39a over a waxing roll 47 which dips into a bath 48 of wax or the like in a tank 49.
  • the filament 37a with a coating of melted wax thereon then passes to the bite of the rolls 20 and 21.
  • the wax maintained at a temperature above its melting point so that a coating is applied to the filament 37a as it passes over the well 47.
  • the filament 37a with its Wax coating is pressed into contact with the filament '10 as the two filaments pass through the bite of the rolls 2% and 21 so that the filaments are bonded together before they are twisted on the ring twister.
  • the wax can be removed by any suitable means such as by heating the yarn to a temperature above the melting point of the wax but below the softening point of the filament material.
  • Various types of low melting wax can be used for this purpose such as bees Wax or carnauba wax.
  • bonding agents may be used such as a bonding adhesive which may remain permanently on the yarn.
  • FIG. 3 illustrates a modified apparatus which may be used in cases where the core filament oarires a heat softenable adhesive or bonding agent.
  • the filament 37b carries a coating of such a heat sottenable bonding agent.
  • This filament is passed through an eye 50 into the heater 17 together with the filament 10.
  • the filament 10 is relaxed so that the bulk reforms and the coating on the filament 37 b is softened so that the two filaments are bonded together by the pressure of the feed rolls 20 and 21 as they are plied together and passed to the ring twister.
  • FIG. 4 illustrates a form wherein the relative rates of feed of the two pairs of feed rolls is varied in a time sequence for thereby controlling the position and amount of bulking which takes place in the heating tube.
  • the upper feed roll Me is mounted on a shaft 51 carrying a gear 52 which is driven by a chain 53 from the shaft 54 of a motor 55.
  • the mating roll 15 not shown is geared to be driven with the roll 14-0.
  • the shaft 51 is connected to the input side of a variable speed device 60 having an output shaft 61 carrying a gear 62 from which a shaft 63 is driven by a chain 65.
  • the shaft 63 carries the roll 200 of the lower pair of feed rolls.
  • Roll 21 (not shown) is geared to be driven with the roll 200.
  • the variable speed device is actuated by a timer 66 in a predetermined time sequence to vary the relative rate of feed of the upper and lower pairs of feed rolls. With the drive in one position, the two pairs of feed rolls are driven at the same speed. With the drive in another position, the upper pair of feed rolls are driven at a higher rate of speed so as to overfeed the filaments to the heater as in the form of FIG. 1 above described.
  • variable speed drive can be adjusted for any desired rate of overfeed so as to control the amount of bulking which is allowed to take place.
  • the variable speed drive may also be set to provide different rates of overfeed in its two positions so that the yarn becmes differently bulked at spaced intervals according to the setting of the program timer.
  • FIGS. 2, 3 and 4 which are identical with those of FIGS. 1 have not been repeated in the latter figures.
  • FIG. A representative product is shown in FIG. wherein the core yarn 37 is shown as substantially straight and the bulked yarn 14 is shown as having bulked portions a and straight portions 10b.
  • the portions lilb correspond to the yarn lengths where the filament 10 is pulled into straight form while in the heater 17 and the portions 10a correspond to the lengths where the filaments are relaxed and rebulked while in the heater 17. While only two filaments have been shown for purposes of illustration it is to be understood that the yarn may be composed of several filaments of each type.
