Definitions

  • This invention relates to flocked fabrics and a novel method of making same. More particularly, the invention relates to flocked fabrics that are made from long, curled sections of synthetic monofilament, which exhibit improved wear, pile resiliency, and general appearance.
  • Flocking is of great importance as a modern method of surface styling for textiles and plastics.
  • natural or synthetic dust, short fibers of different staple length and denier, or flocks of definite length and diameter are cemented by a bonding agent to the entire surface or part of it, of textiles, non-Wovens, or plastic or metal foils, and also to leather, rubber, wood, paper, glass and sheet metal/
  • flocked material always consists of basic material, bonding (agent and pile.
  • FIGURE 6 is a schematic view of a mechanical process employed for manufacturing the flocked fabrics of the invention.
  • FIGURE 7 is a schematic view of an electrostatic process employed for manufacturing the flocked fabrics of the invention.
  • FIGURE 1 flocked fabrics having relatively long, straight filament sections 12 tend to be flat on the fabric surface 10.
  • FIGURE 2 there is illustrated the remarkable advantages of using a filament section 13 in flocking a fabric.
  • a great degree of resiliency and fiber density can be tailored into the finished flocked fabric.
  • FIGURE 3 and FIGURE 4 more clearly illustrate the unexpected result of pile density and resiliency built into the flocked fabric using curled filaments.
  • FIGURE 3 illustrates the poor covering of straight, non-curled filaments and shows their'tendency to lie down on the fabric backing rather than standing perpendicular. This effect is well known in the art and is the main, reason long filaments are generally omitted from most flocking methods.
  • FIGURE 4 In contrast to the inadequate fabric of FIGURE 3, is the flocked fabric illustrated in FIGURE 4, wherein curled filaments comprise the pile surface, of the fabric. It can be seen readily that the curled fabrics tend to interlock, causing a much greater resiliency and density than is normally found in flocked fabrics using long filaments.
  • the filament sections useful for the present invention have a length of from about A to 1 /2 inch and are preferably in the range of 15 to 1250 denier, depending on choice of polymer filament.
  • filament sections are shown possessing varying curl.
  • the degree of curling was established using a /2 inch cut flock and measuring the radii of curvatures, which preferably run from' to A inch. This can be better. understood by referring to FIGURE 5e, wh e rein the dotted,
  • FIGURE 5a would of course, be inch curvature, with FIGURE 5] beof thermoplastic monofilaments and then applying the curled sections of monofilament to an adhesive coated suitable fabric backing material.
  • Flocked fabrics produced in this manner possess a pile density, resilience, durability and attractive appearance that are novel to the. flocked fabric art.
  • FIGURE 5b has inch curvature, 50 having V inch curvature, and so forth. There is a variance in'desirable degree of curl, depending on the particular properties desired in any given'flocked. fabric.
  • FIGURE 5 is merely for purposes of 'il-i lustration and is not to be construed as limiting the inven-,' tion herein.
  • FIGURE 6 there is illustrated schematically one method of manufacturing the flocked fabrics of the present invention.
  • The-method consists essentially of passing a suitable fabric material 16 onto a conveyor 24, where a suitable adhesive 19 is uniformly coatedonto fabric 16 and smoothed by a doctor blade 28.
  • the adhesive-coated fabric 20 is then conveyed beneath a flock distributing device 26 which drops the cut filament sections 25 ontothe coated fabric 20.
  • the finished fabric 30 is then conveyed on to subsequent drying and like treatments.
  • FIGURE 7 illustrates an alternative method employing electrostatic flocking, as opposed to mechanical flocking of FIGURE 6.
  • the essential steps This was flocked onto a 225 square inch sample of Woven SFM, and coated with 16 ounce per square yard of acrylic adhesive, as in Example 1, above. Flock in the amount of 2.14 grams was retained on the backing. The density of flock on the sample was 12.3 ounce per square yard,
