Definitions

  • substantially parallel means that fibers of a unidirectional layer are spaced apart from each other so that the fibers do not contact adjacent fibers of the fibers of the unidirectional layer of fibers.
  • spunbonded and “spun-laid”, mean the production of a nonwoven layer of fibers, wherein the fibers are extruded from a spinneret and subsequently laid down on a conveyor belt as a web of filaments and subsequently bonding the web to form a nonwoven layer of fibers, or by a two-step process wherein filaments are spun optionally drawn e. g. using drawing godets or a jet of pressurized air and wound on bobbins, e.g. in the form of multifilament yarns, followed by the steps of unwinding the multifilament yarns and laying the filaments down on a conveyor belt as a web of filaments and bonding the web to form a nonwoven layer of fibers.
  • fibers refers to both staple fibers and filaments.
  • Staple fibers are fibers which have a specified, relatively short length in the range of 2 to 200 mm.
