Definitions

  • the invention relates to a shoe insole, in particular a midsole or insole for shoes, such as work or safety shoes, with a binder and, if appropriate, fillers containing nonwoven fabric.
  • DE-PS 19 17 587 also describes the addition of metal, preferably steel fibers to a laminate made of different fiber materials.
  • Conductive cloths made of a fleece with metal fiber content for filter purposes have been described in "Textile Institute and Industry” 7 , 1972, p.199.
  • US-A-4750418 describes a sole whose insole consists of a nonwoven material impregnated with a particulate conductive material.
  • the object is achieved according to the invention by means of a shoe insole, in particular a midsole or insole for work or safety shoes, with a nonwoven fabric containing binders and possibly fillers, in which the nonwoven fabric has a fiber mixture with between about 1 to 10% by weight of electrically conductive step fibers .
  • nonwovens can be used as the nonwoven fabric, such as needled nonwovens, random fiber nonwovens or the like.
  • the fiber mixture of the nonwoven fabric can be synthetic, and / or have natural and / or regenerated fibers.
  • synthetic fibers for example, polyester fibers, nylon fibers, etc. The like. Or mixtures thereof have been found to be inexpensive, in particular because of their high durability, but in part also because of the inexpensive price.
  • Particularly preferred electrically conductive fibers are those which have at least one highly conductive and flexible metal, such as copper, iron, aluminum, or which are fibers coated with a conductive metal. It is also possible to use elemental carbon.
  • the conductive fibers can have a titer of 1-18 dtex, preferably 3-12 dtex.
  • a typical stack length of the conductive fibers is 20 to 80 mm.
  • the volume resistance through the sole at an applied voltage of 100 volts can be less than or in the range of 1 x 105 ohms, preferably approximately equal to or less than 1 x 104 ohms.
  • the binder is preferably hydrophobic, for example nitrile-butadiene rubber and / or styrene-butadiene rubber latex is suitable.
  • the sole has a bactericidal agent for foot hygiene and as material protection.
  • the sole 10 has a nonwoven fabric that is traversed by thin steel fibers 12.
  • a needled non-woven fabric consisting of a mixture of polypropylene with polyester fibers and 2% by weight steel fibers with a thickness of approx. 9 dtex and a length of approx. 40 mm with a weight of 350 to 550 g / qm and a thickness of 2-3 mm is impregnated with 100% by weight of a mixture of nitrile butadiene rubber and styrene-butadiene rubber latex, dried at 150 degrees Celsius and vulcanized.
  • the binder-bonded nonwoven is then sanded on one side, the sanded side resulting in a foot-friendly surface.
  • the material is used in a manner known per se for the production of a midsole and has a resistance of 10 ohms at a voltage of 100 volts applied across the sole thickness.
