Definitions

  • the fibers are arranged as a coherent web and retained therein by either an entanglement of the respective fibers or a bonding thereof together without firstly spinning the fibers into yarns and interlacing the yarns by the conventional textile operations of weaving, knitting, braiding, and the like.
  • nonwoven fibrous materials are nonwoven textiles, wool blend felts, needled and shrunk felts, and battings.
  • the nonwoven fabric is conventionally referred to as a unidirectional fabric, and where the fibers are random laid, the fabric is referred to as an isotropic fabric. Bonding of thermoplastic fibers may be accomplished by application of heat and pressure. Another conventional method of bonding the fibers is by means of a liquid adhesive or binder.
  • binders has presented a number of problems, such as requiring curing to provide water insolvent resistance, poor light stability, discoloration, and gradual stiffening.
  • a further feature of the invention is the provision of a porous metal structure wherein the fibers are interlocked in intermingled relationship substantially solely by means of rough outer surfaces thereof in friction engagement.
  • Still another feature of the invention is the provision of a porous metal structure wherein the individual fibers are unburnished.
  • Another feature of the invention is the provision of a porous metal structure wherein the fibers have high compressional resilience.
  • Still another feature of the invention is the provision of a porous metal structure wherein the fibers comprise stress relieved, annealed fibers.
  • a still further feature of the invention is the provision of a porous metal structure wherein the fibers are arranged in a compacted arrangement.
  • Another features of the invention is the provision of a porous metal structure wherein the fibers are disposed in a felt arrangement.
  • Yet another feature of the invention is the provision of such a porous metal structure which is creped to have a preselected resilient extensibility.
  • FIGURE 1 is a fragmentary section of a porous metal structure embodying the invention
  • FIGURE 2 is a fragmentary side elevation of a metal fiber for use therein;
  • FIGURE 8 is a transverse section taken substantially along the line 8-8 of FIGURE 7;
  • One method of forming the staple fiber is to break the filaments to form a continuous band of the broken fibers commonly called a sliver, such as sliver 28 illustrated in FIGURE 12.
  • a method of forming the sliver 28 from the tow 24 is illustrated in FIGURE 11 wherein the continuous filament tow 24 is fed through a breaking apparatus including a plurality of in-feed rollers 29, a plurality of intermediate section rollers 30, heater means 31 for heating the tow as it passes around the rollers 30, breaker bars 32, front rolls 33, and a crimper means 34. As shown in FIGURE 11, the tow 24 remains unbroken up to the breaker bars 32.
  • the individual fibers of the laminated web 41 extend generally parallel to the plane of the web so that the rough frictional characteristics of the fibers tends to hold them in the compacted state resulting from the creping operation whereby an effectively irreversible compacting occurs providing the desired reduced area and thickness of the metal structure 10.
  • the structure 10' may be returned into the creper 44 crosswise to the original direction of creping so that a further creping or compacting may be effected at right nagles to the original creping.
  • the fibers are formed of 304 stainless steel, a total reduction in area of the web 41 of as much as may be effected by such double right angle creping.
