LAMINATE MATERIAL FOR PRODUCING FOOTWEAR, AND DEVICE PRODUCED THEREFROM

摘要

The laminate material for the production of an item of footwear has a sublaminate which is constructed from a support layer which can be stretched in two directions and a compressible layer. The support layer has at least two sorts of interwoven fibres, at least one sort of fibres being made of an elastic substance. The sublaminate is at the same time flexible, shape-restoring, soft, protective, and also breathable. A characteristic feature of the invention is the fact that the laminate material comprises a layer with a phase change material (PCM), known as a PCM-containing layer. An example of a PCM is paraffin. In the case of a supply or discharge of energy in the range of the melting point of the PCM, the material maintains its melting temperature during the phase transition from a solid to a liquid state or vice versa. This effect is used to regulate the temperature of the laminate material. This allows the temperature of a body part within the laminate material to be kept at a constant temperature.
