Definitions

  • thermoplastic material such as nylon, Dacron, etc.
  • This novel yarn is produced according to the invention through the passage of continuous filament thermoplastic yarn through a heating zone and then over a relatively cold,, sharp-edged surface to impart a substantially permanent latent crimp thereto, and intermittently substantially reducing the application of heat to the yarn prior to passage over the sharp edge.
  • this reduction in the amount of heat imparted to the yarn is effected mechanically through the mediumf of a lifter arm which is moved intermittently to raise the yarn on of a contact heaterstrip over which the yarn normally passes in engagement prior to passing over the sharp edgeof a blade.
  • This intermittent movement of the lifter arm and yarn may be effected in any desired manner and'may be accomplished at periodic intervals or preferably at random intervals.
  • the yarn which. is processedlaccording to this method maybe single filament 'or preferably multi filament synthetic thermoplastic ma- -terial of any desired content or blend, including nylon, Dacron, etc; nylon being the preferred yarn material.
  • novel yarn produced according to this invention will have alternate segments which are respectively both heat relaxed and permanently cn'mped (the crimp being substantially latent prior to development thereof by subsequent crimp developing treatment), corresponding to the segments which have fully engaged both the heater strip and the sharp blade edge, and substantially non-heatpreferably agitated in a bath of liquid, such as water,
  • FIGURE 1 is a schematic illustration in perspective of a single yarn processingv position according to the invention, showing the normal heat setting and crimping position of the apparatus and yarn in full lines and the reduced heat setting and crimping position'of the apparatus and yarn in; broken lines, i
  • FIGURE 2' is a schematic illustration of a fully developed length of yarn according to the invention.
  • FIGURE 3 is a schematic view in perspective of a I fabric constructed of yarn according to the invention.
  • FIGURE 4 is a schematic section View illustrating the general appearance of the edge of the fabric along line
  • a thermoplastic yarn is progressed from a suitable yarn supply such as a bobbin or pirn 11 through a suitable guide arrangement 13 and ten'sioning device 15, through an intermittent texturizing device generally indicated at 17, and thence to a takeup device such as a ring and traveler twister takeup 18.
  • the yarn texturizing device 17 includes a yarn heating element in the form of .a heater strip 19 over which the yarn Y normally passes in substantial'contact, a sharpedged crimping element in the form of a sharp edged (e.g.
  • the lifter arm 25 has an outer transverse end 25a which is formed for engagement beneath the yarn Y to lift the yarn during clocl wise pivotal movement of the pivot shaft 27 and arm 25 as viewed in the figure.
  • This raising of the yarn lifter arm 25 may be effected through any desired angle, and the angle may be'varied to effect a desired amount of lifting of the yarn oflf "the heater. It is normally preferred A 'Dhe lifter arm maybe raised andlowered in any suit- 'ment therein.
  • the fabric When developed inthe fabric the fabric is to raise the arm substantially completely off the heater in .order to effect the greatest differentiation inthe alternate segments of the yarn,,,, although it willbe apparent'that in some instances it 'Will be desirable to raise the yarn by a lesser amount, thereby onlyidecreasing the amount of heat imparted thereto by the heater strip and effecting a less pronounced diiferentiation between the alternate seg ments of the yaru.
  • the angle of movement of the lifter arm may be restricted by the engagement of the solenoid armature 31a with the opposite ends of the solenoid coil winding casing 31b, or other stops may be suitably employed to effect this limiting action on the lifter arm movement if desired.
  • the tension of the yarn may be varied over a substantial range dependent upon the denier of the yarn and the number of filaments therein, as well as the particular material of the yarn.
  • the tension of the yarn while fully engaging the heater is normally lower than the tension of the yarn in the raised position.
  • the tension of the yarn on the output side of the blade 21 when the yarn is engaged fully on the heater in the normally running position may be between 5-7 grams for 30 denier, filament, nylon yarn, with the tension of the yarn in the raised position being 8-l0 grams or the like, this being merely by way of illustration.
  • the tension may be increased.
  • the temperature of the heater strip 19 should be sufficiently high to raise the temperature of the yarn Y or at least the surface temperature of the yarn to a point between the second order transition point and the first order transition point for the particular yarn being run.
  • This temperature in the yarn may normally be obtained by maintaining the heater strip at a temperature approximately the same as or slightly higher than the temperature to which it is desired to heat the yarn While in contact therewith, depending upon the rate of yarn travel therepast.
  • FIGURE 2 there is schematically shown a single multi-filament yarn which has been processed according to the present invention and which has been subjected to a full development of the latent bulk and crimp imparted to the yarn by the intermittent bulking and crimping apparatus as described above.
  • the bulked and crimped portions of the yarn are indicated by the numeral 41, whereas the substantially unbulked and uncrimped portions of the yarn are indicated at 43.
  • the bulked portions correspond to those incremental segments of the yarn wherein the yarn removal arm is in the nonremoving portion and the initial portions of its removing and replacing portion, whereas the substantially nonbulked and noncrimped portions of the yarn represent those incremental segments which have been passed through the apparatus while the yarn removal arm is in a position to effect substantially full removal of the yarn from the heater. It will be noted that there is a gradual change between the maximum crimped and bulked portions of the segments 41 and the adjacent substantially uncrimped and unbulked incremental segments 43.
  • FIGURE 3 there is schematically illustrated a fabric F which has been formed of a yarn according to the present invention, the fabric having been made from the yarn prior to development of the yarn and the yarn having been developed after formation of the fabric. Due to this subsequent development of the yarn in situ in the fabric there is both a development of bulk and elasticity of the yarn in those incremental segments 41 which were passed over the blade in substantially heated relation as a result of being in substantial contact with the heater, and also a creping effect imparted to the fabric areas having these segments therein as a result of heat shrinkage of the basically unheated treated incremental segments 43 which did not receive any substantial heat development during their passage about the heater element.
  • the elasticized and bulked segments are indicated in the fabric at 41a by the raised and more bulky areas, and it will be noticed that the appearance of the creping or wrinkles 41a in the face of the fabric is enhanced by the relatively flat areas 43 where the yarn segments 43 lie. While this one particular embodiment of a fabric is illustrated, it will be understood that this is only by way of example, and that many other constructions might be made Within the scope of the invention, such as the development of the yarn prior to formation in the fabric, the formation of the fabric with the yarn in both the warp and the filling, etc.
