TEXTILE PRODUCT FOR ATTENUATION OF ELECTROMAGNETIC FIELD AND THE DEVICES FOR MANUFACTURING THE TEXTILE PRODUCT ATTENUATING ELECTROMAGNETIC FIELD

摘要

The subject of this invention is a textile product attenuating electromagnetic field and a device for manufacturing textile materials attenuating electromagnetic field by coating a textile material with coatings deposited by magnetron sputtering method, whereby the textile materials are intended for applications such as electromagnetic shields, used especially in hospitals, office blocks, dwelling houses and laboratories, and which may be used for manufacturing of wallpaper, curtains, blinds and roller blinds. The textile product has at least one layer (L1, L2, L3, L4) of metal and/or at least one layer (L1, L2, L3, L4) of metal oxide with the thickness below few micrometers, formula I, deposited on a substrate (S) alternately, where the number of the (L1, L2, L3, L4) layers depends on the coefficient of shielding efficiency of electromagnetic field by the textile product. Inside a vacuum chamber, above the conveying device fixed to the base (10) there is a three-layer anode in a shape of a part of cylindrical surface, mounted with insulators (6) on the base (10) fixed to the chamber housing. The anode, on the side of the target (1 1), has a sliding layer (5) and under this layer, a layer of supporting structure (4) while on the bottom, there is a temperature stabilizer (3) to which a cooling system made of a set of pipes (2) transporting the cooling medium is mounted. Above the three-layer anode there is a magnetron sputtering device (1) equipped with a rectangular target (11), connected to a supplier (27) which is coupled through a control system (26) with a computer unit (25). The control system (26) is connected through a valve controller (28) with a control valve (29), an instrument for measuring the length of a coated fabric (30), and simultaneously, through a engine velocity governor (31) with a motor (32) driving a two-way drive (9) of the conveying device.
