Definitions

  • This invention relates to improved apparatus for handling running filaments, thread-s, yarns, strands, ribbons, films, and other thin, elongated structures. More particularly, it relates to apparatus having exceptionally high resistance to wear and characterized also by low friction when used in contact with thin, elongated structures on the run.
  • the surfaces of various apparatus elements are in contact with the structure as it is advanced.
  • Such surfaces customarily include the surfaces of rolls, pins, guides, and the like.
  • the apparatus accordingly has an effective wear life of only a few days or weeks, after which the apparatus must be discarded or the surface renewed by grinding or by an appropriate plating or coating process, according to the nature of the surface.
  • the short wear life of apparatus elements has been a major economic problem in many yarn applications and a need has therefore been felt for more durable apparatus.

  • Contacting elements 16, 1, 6, i0, 24, and 6 each have a hard, low friction continuous surface 5 containing at least 50% chromic oxide, the spinneret 23 and wind-up roll 25 acting as means for delivering the yarn to and from the contacting elements.
  • Solid chromic oxide guides, pins, or other articles are prepared by molding or pressing chromic oxide powder in the desired shape, fusing or sintering the shaped article, and then grinding or lapping the yarn-contacting surface to the desired smoothness.
  • metallic apparatus of the desired design is first fabricated in the usual manner. Stainless steel, aluminum, or any other metal generally suitable for the fabrication of metallic apparatus may be used. The surface or surfaces to be provided with the chromic oxide coating are then cleaned to free them from particles of rust, organic substances, and other materials. Preferably the surface is roughened, such as by sand blasting it.
  • the chromic oxide coating is then applied to the metallic apparatus by any of the various known flame-spraying, arc spraying, or coating methods using chromic oxide in the form of a rod or in powdered form, the chromium oxide being heated to the molten state and projected or sprayed upon the metallic surface in the form of fine globules which are thereby bonded to the metallic surface.
  • the heating of the chromic oxide may be accomplished by means of a flame produced by chemical burning, such as an oxyacetylene flame, either in the form of a continuous fiarne or as a continual series of detonations. Heating may also be accomplished by electrical means, such as a plasma jet or arc.
  • the as-sprayed chromic oxide surface is not suitable I as such for use on apparatus for handling textile materials and films, since the as-sprayed surface is too rough and contains numerous sharp surface irregularities which not only result in a high coefficient of friction but also cause damage to the yarns and films which are processed thereon.
  • the as-sprayed surfaces are therefore smoothed down 7 l by grinding, lapping, or brushing procedures in preparing the surfaces for actual use in their various applications. If desired, the surfaces may be ground down substantially smooth; however, for minimum friction and for maximum resistance to wear, the rough surface of the assprayed chromic oxide coating is converted to a surface characterized by smoothly rounded nodules. This is accomplished by smoothing down the surface only partially by means of brush-finishing or tumbling techniques.
  • an abrasive material such as particles of silicon carbide may be applied in an aqueous slurry to the assprayed surface by a power-driven brush sufficiently long to smooth olf sharp peaks in the surface and to reduce the surface roughness to a value in the range 70-250 R.M.S. (root mean square) microinches.
  • the chromic oxide coated surface is found to contain numerous smoothly rounded nodules.
  • apparatus provided with such a surface is characterized by low coefficient of friction, in the range 0.18 to 0.22 for most textile yarns, and an exceptionally long wear life.
  • the brushing technique may be continued until a lower level of surface roughness is achieved. For most purposes, a surface roughness in the range of about 15-40 R.M.S. microinches is regarded as being quite smooth.
  • the as-sprayed chromic oxide coating may also be converted to a smoothly rounded nodular surface by means of a tumbling technique.
  • the apparatus having the as-sprayed chromic oxide coating may be placed in 'a tumbling tank having a rubber internal lining and tumbled in an aqueous slurry of 240 grit size silicon carbide for a time sulficient to reach but not go below 70-250 R.M.S. microinches surface roughness and to smooth off sharp peaks in the surface.
  • the time required to achieve this result depends upon conditions, but fr'eqently is in the range of from 2 to about 4 hours. Of course, if a smoother surface is desired, the tumbling process is carried out for a longer time.
  • compositions comprising mixtures of metallic oxides containing at least about 50% chromic oxide are useful. Mixtures of 50-90% chromic oxide and 50-10% aluminum oxide are preferred compositions in the fabrication of textile apparatus flamesprayed or coated with the chromic oxide coating, since the mixtures can be processed in the flame-spraying or coating technique even more readily than pure chromic oxide and are also more readily brushed to the desired surface characteristics.
  • thin elongated structure is used herein to denote a shaped article, particularly a shaped article of a polymer, in which at least one dimension of the structure is relatively quite large and at least one dimension of the structure is quite small. characteristically, the cross section of the structure is also substantially uniform at any point on the long dimension of the structure.
  • the expression therefore comprehends ribbons and films as well as filaments and yarns.
  • Example I Cylindrical draw pins composed of mild steel and having the dimensions 1.5 inches (length) x inch (diameter), are provided with various surfaces, as follows. One set of pins is chrome plated and then polished smooth, the final step being a diamond lapping. The thickness of the polished chrome plating is 3 mils. Additional sets of the steel pins are provided with various ceramic coatings by flame-spraying the sand-blasted surface of the pins with the appropriate ceramic material, using a detonation gun. The ceramic coated pins are then ground down to a high polish, the final step being a diamond lapping. In each case the thickness of the coating is approximately 3 mils. In a series of experiments, the wear resistance of the various pins when exposed to moving yarn is then recorded.
  • the yarn is 40 denier, 27 filament, zero twist, dull yarn composed of polyethylene terephthalate containing 2% TiO
  • the yarn speed is 600' yards per minute, the contact angle of the yarn around the pin is and the tension of the yarn approaching the pin is controlled at 10 grams.
  • the pins are examined at frequent intervals, and the test is stopped as soon as a distinct wear track is observed on the surface of the pin. The time required for the appearance of a distinct wear track in the pins tested is given below for each of the coating materials employed.

  • Example 11 Solid ceramic pins, 1.5 inches long and inch in diameter, are molded by conventional techniques and are then polished smooth in a series of grinding steps, the final step being a diamond lapping step. The pins are then subjected to the same yarn wear test described in Example I. The results are reported below.

  • Example 111 A steel draw roll of the type shown in FIGURE 1, 4 inches long and 6 inches in diameter, is roughened by sand blasting and a continuous coating of chromic oxide 6 mils thick and having a surface roughness of about 250 r.m.s. (root mean square) microinches is flame-sprayed upon the surface of the roll using a detonation gun.
  • the coated surface is brush finished to a surface roughness of about 200 r.m.s. microinches using a power driven brush and an aqueous slurry of 240 grit size silicon carbide.
  • the finished surface is a smoothly rounded nodular surface having a coefficient of friction of 0.2.
  • a sand-blasted aluminum roll when flame-sprayed with chromic oxide and finished as described above, has a long wear life similar to that of the steel roll provided with the chromic oxide surface.
  • Example IV A steel pigtail guide of the type shown in FIGURE 7, having an overall length of 5 inches and an inside loop diameter of inch, is sand-blasted at the looped end to a point on the guide well past the loop. A mixture of 50% chromic oxide and 50% titanium dioxide is flamesprayed onto the guide to provide a continuous coating about 0.0015 inch in thickness and the coated guide is lightly brush finished. When employed with dull polyethylene terephthalate yarn, the guide has an excellent wear life.
