Definitions

  • This invention relates to improvements in polyester fibers, and more particularly to a unique combination of special polymer compositions with fiber cross-section/filament deniers that provide desirable fabric properties heretofore unavailable in fabrics produced of conventional 100% polyester and polyester- rich (i.e., at least 50% polyester) blended fabrics, such aB are suitable for conventional home washing and drying without loss of attractive appearance.
  • PET polyethylene terephthalate
  • Conventional polyethylene terephthalate (PET) apparel fibers are generally of round cross-section and have many attractive characteristics. These include but are not limited to: good physical properties for processing into fabric and thereafter into wearing apparel good durability after washing/drying by conventional means and good color light fastness.
  • rayon f brics have other important disadvantages, e.g., they do not retain their desirable attributes after repeated subjection to conventional home wash/dry cycles, so preservation of such attributes requires that the fabrics and garments be cleaned by professional methods. It has long been desirable to modify conventional polyester fibers, to retain their important advantages, but to impart also some characteristics of new rayon fibers. Some techniques have been suggested to modify polyester polymers (e.g. reduction of polymer viscosity, and incorporation of modifiers, and special treatments) to reduce the tendency of the fabrics to "pill". This has had varying degrees of success with conventional round filament cross-sections. Because use of these modified polymers can lead to undesirable and even excessive spinning discontinuities, however, their use for non-round cross-sections has been more appropriate for high deniers per filament (dpf) that have been unacceptable for usage in apparel.
  • dpf high deniers per filament
  • Scalloped-oval cross-section ibers produced from conventional polyethylene terephthalate polymers have been used heretofore for specialty areas, e.g. pile fabrics, carpets, paper reinforcement and filters, but the deniers per filament (typically 6 and above) have been higher than what is needed for most apparel applications. Textile deniers of up to 3 dpf have been used, but their pilling performance has inhibited full commercial acceptance.
  • the polymer modifier is polyethylene oxide (PEO) of molecular weight in the range 200-2000.
  • PEO polyethylene oxide
  • the viscosities of the polymers are indicated herein, and correspond to the molecular weights of the polymers.
  • the fibers of the invention may be made conveniently by melt spinning and drawing un-delustered modified PET filaments of appropriate viscosity, denier per filament, and cross-section, as disclosed herein-after in the Examples.
  • the filaments are generally cut to staple of whatever length is desired for the end-use contemplated, e.g., about 10 to about 100 mm. Deliberately mixed deniers are advantageous, and may be used. It will be understood that both the terms "filament” and “fiber” are used generically herein. While the primary application discussed here is staple, it is believed that continuous filament applications in the form of yarn or tow would provide similar desirable luster benefits when converted into fabrics, woven or knitted.
  • Clear polymer means that the fiber is not 15 delustered, that is, contains essentially no added delustering pigment, generally less than 0.005 percent by weight of delusterant (typically titanium dioxide pigment) .
  • a molecular weight of 600 for the PEO was 25 used because it was convenient, but may vary from about 200 to about 2000.
  • the molecular weight must be high enough to be effective, but low enough to be applied practically. Heat can be used to effectively use a higher molecular weight PEO.
  • each of the elements of the present invention namely the selected PET polymer(s) and modifier, the selected viscosity, r the absence of delusterant, the scalloped-oval filament cross-section, and the apparel deniers, 35 have been used separately for various textile and industrial end-uses but have not, so far as we know, been used in the present combination, nor for this purpose, and the results are surprising.
  • the invention is further illustrated in the following Examples.
  • the PEO was of molecular weight 600.
  • the relative viscosity of the polyester was measured essentially as described in Hancock et al. U.S. Patent No. 4,704,329, col. 9, lines 6-11, but on a solution obtained by dissolving 0.80 gram fiber in 10.0 milliliters solvent.
  • the DDR (Dye
  • a commercial clear PET polymer with essentially no titanium dioxide, but containing 3.9 weight percent of polyethylene oxide (PEO) and 0.175 weight percent trimethylol propane, to provide a relative viscosity of 20.5 was utilized. It was melt spun at 290 C and 102 pounds per hour through a spinneret having 1653 capillaries.
  • the capillary orifices were of the general configuration of that shown in Figure 2 of U.S. Patent 4,707,407, with the major axis length being 0.039 inches and the minor axis length being 0.019 inches.
  • the filaments were conveniently collected at 1500 yards per minute on individual bobbins using a commercial wind-up device.
  • Fiber from the Item 3 was cut to 1 1/2" on a standard cutter, baled and processed on commercial textile machinery to a ring spinning frame.
  • the yarn count was 25/1 cc with a 4.0 twist factor.
  • the yarn was woven into a 2 X 1 twill fabric on a standard loom using 112 ends per inch on the warp and 58 picks per inch in the fill. This fabric was dyed atmospherically with disperse dyes without carrier for one hour. Commercial fabric softener was applied. Without further treatment, the fabric was tested on the Random Tumble Pill Test Mechanism. After 10 and 60 minutes tumbling, respectively, the pill ratings were 4.2 and 2.6 (higher pill ratings indicating better resistance to pilling) .
  • Example 2 The yarn count was 25/1 cc with a 4.0 twist factor.
  • the yarn was woven into a 2 X 1 twill fabric on a standard loom using 112 ends per inch on the warp and 58 picks per inch in the fill. This fabric was dyed atmospherically with disperse dye
  • Example 1 A commercial polymer similar to that used in Example 1 was melt spun at 285C and 68.5 pounds per hour through spinnerets having 1054 capillaries, but otherwise essentially similarly to Example 1, except that the major axis length for the capillary orifice was 0.030 inches.
  • the filaments were conveniently collected at 1500 yards per minute from multiple positions using a commercial device.
  • Nine hundred ends were combined as a creel for a commercial drawing machine. They were one-stage drawn, crimped, and relaxed in a hot air dryer. The results of this test are included as Item 1 of Table 2. 2.
  • a heavier denier was produced at a spinning rate of 63 pounds per hour using spinneret of 450 capillaries.
  • the capillary had the major axis length of 0.039 inches as in Example 1.
  • Nine hundred eighty four ends were combined as a creel for a commercial drawing machine. They were one-stage drawn, crimped, and relaxed in a hot air dryer. The results are of this test are included as Item 2 of Table 2.
  • Example 3 A commercial polymer similar to that used in Example 1, except for having an relative viscosity of 19.8, was melt spun essentially as in Example 2, except at 292C and 96 pounds per hour through spinnerets having 1653 capillaries into filaments that were conveniently collected at 1421 yards per minute .
  • Six hundred thirty ends were combined as a creel for a commercial drawing machine. They were one-stage drawn, crimped, and relaxed in a hot air dryer at 124 C. The results of this test are included as Item 1 of Table 3. 2-3.
  • To evaluate relaxation temperature effect on "pill resistance” material that was spun, drawn, and crimped as Item 1 of Table 3 was not allowed to enter the relaxation dryer. It was taken to a laboratory forced convection, hot-air oven, one sample was exposed to 130 C air for 5 minutes, the other to 160 C air for 5 minutes. These results are reported as Items 2 and 3 of Table 3 respectively.
  • Filaments from the above four items were randomly selected from the processed but uncut filament bundle. Individual filaments were tested for flex life by being clamped between two bars having a 0.001 inch radius at the point of nip. A dead weight loading of one gram was applied and then the bars were oscillated in a manner calculated to flex the filaments in opposite directions until rupture occurred. This data is reported in the Table 3 as "flex life". A lower flex life indicates that the resistance to pilling is likely to be better.
  • the pill ratings were, respectively, for Item 3.1; 4.5 and 4.4, for Item 3.4: 3.8 and 1.6, and more yarns, prepared from item 3 in Example 1, were similarly woven and tested to give RTP ratings, respectively, of 4.5 and 2.6.
  • Example 2 A commercial polymer similar to that used in Example 1 (except for relative viscosity of 19.7), was melt spun at 293 C and 75 pounds per hour through spinnerets having 1054 capillaries, using capillary orifices as in Example 2.1. Four hundred forty eight ends were combined as a creel for a commercial drawing machine. They were one-stage drawn, crimped, and relaxed in a hot air dryer at 142 C. The results of this test are shown in Table 4. TABLE 4
  • Fiber from Example 1, item 3 was blended 50/50 with combed cotton and ring spun into 28/1 cc. It was knit into a 22 cut Jersey fabric on a commercial machine. The fabric was atmospherically dyed and subjected to the standard Random Tumble Pill test method.
  • T-107 W round, 11.5 RV homopolymer
  • This comparison fiber was likewise blended 50/50 with combed cotton and ring spun to 28/1 cc. This yarn was knit on the same knitting machine into a 22 cut jersey, dyed with carrier and subjected to the standard Random Tumble Pill test method.
