Embodiment 2

[0164] A barrier material in which both fiber components consist of polyester, 50% by weight each of the total fiber composite, and the second fiber component is side-by-side polyester Bico.

[0165] The barrier material of Example 2 was made in the same way as the sheath-core Bico-fiber of Example 1 and had the same properties, except for the characteristic Bico-structure.

Embodiment 3

[0167] A barrier material comprising 50% by weight each of two fiber components, the first fiber component consisting of polyester and the second fiber component consisting of polypropylene.

[0168] In this example, instead of Bico, monocomponent fibers are used as the second fiber component. For the production of fiber composites, only two fiber components with different melting points are selected. In this case, 50% by weight polyester fiber (melting point about 230°C) is the carrier component, while the same 50% by weight polypropylene fiber has a lower melting point of about 130°C and is used as an adhesive Connected reinforcement components. In addition, the production process was carried out as in Example 1. Compared to Example 2, the nonwoven of Example 3 has a lower thermal stability, but it can also be produced at lower temperatures for this.

Embodiment 4

[0170] 80% polyester was used as the first fiber component and polyester sheath-core Bico as the barrier material for the second fiber component.

[0171] In this example, production takes place again as in example 1, with the difference, however, that the proportion of the second fiber component forming the reinforcing component is changed. Compared to 80% by weight of the first fiber component with a higher melting point, only 20% by weight of the second fiber component remains. By scaling down the strengthening component, the stabilization effect of the resulting barrier material is also reduced. This can be beneficial if a nonwoven material with high mechanical stability and high flexibility at the same time is required. The temperature resistance of this nonwoven corresponds to that of the first embodiment.

[0172] use Figures 4 to 11 Several examples for composite soles or blocking units or details therein are investigated.

Abstract

The invention relates to a steam-permeable composite shoe sole (105) with an upper part (50), comprising at least one opening (31) extending through the depth of the composite shoe sole, a barrier unit (35) having an upper part that forms at least a section of the upper part (50) of the composite shoe sole (105) and having a steam-permeable barrier material (33) that is configured as a barrier toforeign matter penetrating the sole, said material obturating the at least one opening (31) in a steam-permeable manner. A reinforcing element (25) is associated with the barrier material (33) for mechanically reinforcing the composite shoe sole (105). Said element comprises at least one reinforcing web (37) that is disposed on at least one surface of the barrier material (33) and at least partially bridges the at least one opening (31). At least one outsole part (117) is arranged below the barrier unit (35).

Description

[0001] This application is an international application number PCT / EP2007 / 001821, the international application date is March 2, 2007. The national application number after the PCT international patent application entered the Chinese stage is 200780007171.5, and the invention name is "Composite shoe sole, made of A divisional application of the Chinese patent application for "shoes and manufacturing method thereof". technical field [0002] The present invention relates to composite shoe soles, shoes made therefrom and methods of making such shoes. Background technique [0003] Since there are both water-gas-permeable and water-impermeable sole surface structures, precisely based on the application of a perforated or equipped with through-hole substrate and a water-impermeable, water-air-permeable function arranged on it, for example in the form of a film layer, there is no longer the necessity of having to decide between a sole surface structure that is impermeable but trap...
