Definitions

  • the diskette liner of the invention comprises a thermally bonded nonwoven structure having five layered webs of three distinct fiber compositions (i.e., A-BBB-C) .
  • a top or "media contacting" layer comprises a web (i.e., the "A” web) containing 25-100% cellulosic fibers, which provide efficient cleaning of the magnetic medium.
  • a "middle layer” is composed of three layered webs (i.e., the "BBB" webs) each comprising a blend of matrix thermoplastic fibers and binder fibers.
  • the binder fibers preferably include low melt and low softening point thermoplastic fibers as well as bicomponent fibers.
  • the low melt binder fibers in the middle layer 110 remain isolated from both the media contacting layer 100 and the cartridge contacting layer 120. If the binder fibers are not isolated from the outer layers, the binder fibers will melt and stick to the calender rolls during bonding unless the temperature of the rollers is reduced. This results in slower processing speeds and poorly bonded fabrics. Additionally, the binder that sticks to the rolls can then flake off and cause debris.
  • the plurality of layered webs 211 is transported from endless belt 210 to an inclined conveyor 212, which transports the layered webs 211 to a heated embossing calender system comprising a pair of counter rotating rollers 214 and 215, where the layered webs 211 are thermally bonded at discrete and recessed bonding points.
  • a heated embossing calender system comprising a pair of counter rotating rollers 214 and 215, where the layered webs 211 are thermally bonded at discrete and recessed bonding points.
  • the purpose of layering and bonding as hereinbefore described and shown in the drawings is to isolate the abrasive bonded and melted thermoplastic fibers away from the surface of the fabric so as to eliminate any possibility of abrasion of the surface of a computer magnetic disk by the liner fabric.
  • Both pairs of bonding rollers 230, 232 and 240, 242 produce an embossed liner 30 having a similar bond pattern on its surface. See FIG. 6.
  • Bonded regions 234 take the shape of a diamond and unbonded regions 236 surround the bonded regions. The invention is not limited to diamond shaped bond spots. Any bond point shape may be used, including but not limited to diamonds, squares, dots and lines.
  • the bond pattern produced by these embossing rollers provides discrete bonding regions 234 which are recessed below the surface of the nonwoven structure and do not come in contact with the magnetic media, thus preventing scratching. See FIGS. 7A-7D.
  • the bonded areas 234 of the liner 30 comprise less than 50%, preferably 25%, of the liner's total area.
  • a second preferred embodiment of the invention provides a nonwoven liner of similar structure and component fibers to the first embodiment except a small amount of latex binder (compared to the weight of the liner) is uniformly distributed throughout the fabric after nonwoven bonding and is principally applied between the plurality of bond points of the fibers.
  • binders to a computer diskette liner was the subject of U.S. Patent Nos. 5,060,105 and 5,311,389, both to Howey, which are incorporated herein by reference.
  • the binder can be applied in a range between 0.1% - 5.0% by weight of the liner, preferably less than 1.0%.
  • Preferred chemical binders are high molecular weight compounds that are usually produced by emulsion polymerization.
  • All fibers in the liner are staple fibers.
