Definitions

  • the invention relates to novel processes for making from a yarn consisting of essentially continuous filaments a yarn simulating one spun from staple fibers.
  • Negishi et al U.S. Patent 4,059,950 described non-uniform drawing a partially oriented filament yarn, at below the natural draw ratio and at a temperature high enough to initiate crystallisation, to produce a yarn having thick and thin portions wherein the thick portions are brittle. Subsequent draw-texturing causes the thick brittle portions to break so that the resulting yarn has protruding thick broken ends. Fabrics made from the yarn have a coarse "touch".
  • the present invention comprises a yarn bundle comprising a plurality of quasi-continuous filaments, each of the plurality of filaments having a non-round cross-sectional area which varies repetitively from small values in thin regions to large values in thick regions along its length, the large values being at least 25% greater than the small values, the thick and thin regions being out of phase from filament to filament along the length of the yarn, and the filaments being repeatedly broken primarily in the thin regions to provide broken ends protruding from the bundle.
  • the process of the invention is one for making a spun-like yarn, comprising melt spinning a feed yarn by contacting molten polymer streams extruded at different velocity, the feed yarn so produced comprising a plurality of continuous filaments, each of the filaments having a non-round cross-sectional area which varies repetitively from small values in thin regions to large values in thick regions along its length, the large values being at least 25% greater than the small values and subsequently drawing the feed yarn at a draw ratio such that a plurality of the filaments are broken primarily in the thin regions.
  • the term "quasi-continuous" is intended to reflect the fact that the filaments are not continuous throughout the length of the yarn, being repeatedly broken in the way defined, yet they are longer than "staple fibres" and otherwise behave as continuous filaments do in forming the main structure of the yarn.
  • the filaments in the yarn bundle have alternating S and Z helical crimp along their lengths.
  • polyester polymer as used herein means fiber-forming polymers at least 85% by weight of which is formable by reacting a dihydric alcohol with terephthalic acid. Polyester typically is formed either by direct esterification of ethylene glycol with terephthalic acid, or by ester interchange between ethylene glycol and dimethyltereph- thalate.
  • FIGURES 1 and 2 illustrate the preferred embodiment of a spinneret design which can be employed for obtaining all aspects of the invention.
  • the spinneret includes a large counterbore 20 formed in the upper surface 21 of spinneret plate 22.
  • Small counterbore 24 is formed in the bottom of and at one side of large counterbore 20.
  • a large capillary 26 extends from the bottom of large counterbore 20 at the side opposite small counterbore 24, and connects the bottom of large counterbore 20 with the lower surface 28 of plate 22.
  • Small capillary 30 connects the bottom of counterbore 24 with surface 28.
  • Capillaries 26 and 30 are each inclined four degrees from the vertical, and thus have an included angle of eight degrees.
  • Counterbore 20 has a diameter of 0.113 inch (2.87 mm.), while counterbore 24 has a diameter of 0.052 inch (1.32mm.).
  • Capillary 26 has a diameter of 0.016 inch (0.396 mm.) and a length of 0.146 inch (3.81 mm.), while capillary 30 has a diameter of 0.009 inch (0.229 mm.) and a length of 0.032 inch (0.813 mm.).
  • Land 32 separates capillaries 26 and 30 as they emerge at surface 28, and has a width of 0.0043 inch (0.108mm.).
  • Plate 22 has a thickness of 0.554 inch (14.07 mm.).
  • Capillaries 26 and 30 together with counterbore 20 and 24 constitute a combined orifice for spinning various novel and useful filaments according to the invention, as will be more particularly described hereinafter.
  • molten polyester polymer of normal textile molecular weight is metered at a temperature of 290°C through a spinneret having 34 combined orifices as above specifically disclosed.
  • the polymer throughput is adjusted to produce filaments of 8 average denier per filament at a spinning speed of 3400 yards per minute (3091 metres per minute), the molten streams being conventionally quenched into filaments by transversely directed quenching air.
  • the slower stream attenuates between the points of attachment 38 and the loops of the faster stream become straightened until the faster stream is brought into continuous contact with the slower stream.
  • the slower stream attenuates more between the points of first attachment than at the points of first attachment so that the resulting combined stream has a cross-section which is larger at the points of first attachment than in the regions between these points.
  • the resulting combined stream is then further attenuated somewhat until it is solidified into a filament 40 by the transverse quench air.
  • Each solidified filament 40 has non-round cross-sectional areas which vary repetitively along its length. As illustrated qualitatively in FIGURE 5, when using the above spinning conditions, the filament cross-sectional area repetitively varies at a repetition rate of about one per meter, although this can be varied by modifying the spinning conditions and the geometry of the spinneret passages.
  • a multiple orifice spinneret will typically provide somewhat different repetition rates among the several resulting streams and filaments.
  • An example of this is qualitatively shown in FIGURE 6, wherein is shown that various orifices produce somewhat different repetition rates as determined by stroboscopic examination of the combined streams just below the spinneret face. The repetition rate is proportional to the stroboscope frequency bringing about apparent cessation (or freezing) of movement of the thick and thin regions of the filament.
  • each filament has a cross-sectional area which varies repetitively from small values in thin regions to large values in thick regions along its length, the large values being at least 25% greater than the small values.
  • Improved spun-like effects in the ultimate textured yarn are obtained when the large values are at least 100% greater than the small values, with optimum results when the large values are between 300% and 500% of the small values.
  • the above feed yarn is simultaneously draw- textured on a Barmag FK-4 texturing machine, using as the false-twist device a friction aggregate of the type disclosed in Yu U.S. Patent 3,973, 383.
  • the draw ratio is set at 1.60 with a winding speed of 385 ypm (about 350 meters per minute).
  • Both heaters are set at 200°C., with an overfeed to the second heater of 10.47% and an overfeed to the winder of 6.79%.
  • the aggregate speed is set such that the yarn tensions just before and just after the aggregate are equal.
  • the resulting yarn has numerous filament breaks primarily in the thin regions, the broken ends protruding from the yarn bundle.
  • the filaments are broken with considerably more control than those in the patents referred to above, and because of the variable denier, fabrics made from the resulting yarns have a much more soft and luxurious hand than those made from prior art yarns with the same average denier per filament. This softness of hand is particularly evident when the cross-sectional areas of the thick portions of the filaments are at least 100% greater than those of the thin portions, and values between 300% and 500% greater are particularly preferred.
