ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a method for the transport of liquid, e.g., perspiration through one or more layers of textiles.
BACKGROUND OF THE INVENTION
In connection with all kinds of garments, and in particular garments used for sports or physical labour, the body exudes perspiration which ideally ought to be transported away from the skin in order to keep it as dry as possible. Since the majority of types of textiles, and especially synthetic textiles, do not have the property that they efficiently transport moisture from the skin, a person, after perspiring, will quite soon begin to feel cold because of the moisture residing in the fabric. This is connected with the fact that the moisture which is removed through evaporation draws much of the heat for the evaporation from the body. One of the few fabrics which seems to have a considerable measure of water transport capacity are woollen fabrics. This is related to the fact that there are capillaries in the wool fibres which have a high liquid transport capacity. When the liquid is drawn away from the skin, evaporation will take place with the aid of heat from the surroundings.
Modern pieces of clothing, and in particular pieces of clothing which are expected to be exposed to perspiration (tracksuits, parka jackets etc.) are often composed of several layers (laminates) of textiles, by means of which an attempt is made to secure insulation together with optimal liquid transport capacity. A known way of optimising this when dressing in cold conditions where perspiration is expected to occur is to have woollen underwear next to the body, which serves to transport the moisture into the outer clothes.
A number of different methods are known which seek to solve this problem in a best possible way. One of these is by using a combination of different types of fibres which have capillary liquid transport properties. German patent publication DE 38 31 970 describes a solution using an electrifiable membrane able to transport liquid according to the principles used in dialysis apparatus.
However, there are no satisfactory solutions which have been put into technical or commercial use, and so the “sweat problem” described above is still perceived as a problem in connection with the aforementioned clothes.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a solution to this problem which cannot only be used on clothes, but which can also be applied to, for example, shoes, tents etc., where there is a need for the transport of liquid through one or more layers of textiles.
The principle of the present invention is that on each side of a textile, or as a part thereof, there are woven therein or printed thereon conductors or semiconductors to which a pulsating direct current is applied which sets the water molecules in motion. The current pulses may be supplied to the conductors or semi-conductors by means of a battery where the current pulses are generated in a small oscillatory circuit built up of a capacitor which is discharged through a short circuit after charging. The current pulses may otherwise be generated by an oscillating generator consisting of a permanent magnet and a coil. The permanent magnet which may be suspended in a spring arrangement, is set in motion by the body's own movements, so that each time the magnetic field cuts through the coil windings, an electric voltage is induced in the coil which gives the desired electrical pulse in the semi-conductors.
