Definitions

  • Footwear with a waterproof and water vapor permeable shaft has been available for a long time, so that such a footwear, despite being waterproof, can now give off sweat moisture in the shaft area. So that even in the sole region sweat moisture can escape, it has gone over to a sole structure, which has an outsole with through-thickness extending through openings and above a waterproof and water vapor permeable sole functional layer, for example in the form of a membrane.
  • a sole structure which has an outsole with through-thickness extending through openings and above a waterproof and water vapor permeable sole functional layer, for example in the form of a membrane.
  • An example is shown in EP 0 382 904 A2, whose outsole has passage openings in the form of micro perforations, with a corresponding limitation of the water vapor permeability.
  • EP 0 275 644 A2 provides that between the outsole with its passage openings and the membrane above it, a protective layer is arranged, for example, of a mesh or felt material, which prevents the foreign bodies passing through the through holes of the outsole from penetrating to the membrane.
  • a further protective layer is arranged between the membrane and the net-like protective layer, which is, for example, a felt layer.
  • WO 2007/101624 A1 Another example of very large sole openings is shown in WO 2007/101624 A1, according to which the large passage openings of the outsole are stabilized by means of stabilizing webs and / or stabilizing gratings. These wear in the through holes fitted water vapor permeable, textile material, such as felt-like material.
  • the shoe sole composite constructed in this way is connected to a shaft whose shaft bottom is closed by a watertight and water vapor permeable shaft bottom functional layer, so that the entire shoe is waterproof and permeable to water vapor.

  • either the passage opening or optionally a plurality of passage openings of the outsole may be closed with individual pieces of the textile material or all passage openings of the outsole are closed with a single piece of textile material.
  • the textile material has two functions. On the one hand, it serves to stabilize the sole structure, in particular in view of the fact that an outsole with large openings itself can not sufficiently contribute to the stabilization of the sole structure. Because the textile material is formed on the one hand with a relatively high intrinsic stability, which benefits the entire stability of the sole structure.
  • a waterproof, water-vapor-permeable membrane is provided over the sole structure, which is protected by the textile material from damage by foreign bodies such as stones which could damage the membrane.

  • the textile material consists of a fiber composite in the form of a thermally bonded mechanically and additionally surface-bonded by thermal surface treatment fleece with two fiber components, which are each constructed with polyester fibers.
  • the first fiber component forms with the higher melting temperature
  • a carrier component of the fiber composite and forms the second fiber component with the lower melting temperature, a solidification component.

  • the textile material which is particularly suitable for the two above-mentioned purposes, namely stabilization and membrane protection, has the disadvantage that its fibrous component serving as solidification component can not be satisfactorily or only insufficiently dyed with the lower melting temperature and therefore in the Fiber composite remains white, which gives the textile material overall an unsatisfactory appearance.
  • This is disadvantageous because the textile material is visible through the large through holes of the outsole.
