摘要： A composite filtering medium comprising a precision fabric, of the type with weft and warp, on the surface of which nanofibres are deposited by electrospinning. A method for producing the composite filtering medium, comprising a step of electrospinning for formation of nanofibres and a subsequent step of deposition of said nanofibres on a base fabric; the method comprises injection of the material for formation of the nanofibres, dissolved in a solvent or mixture of solvents, through a nozzle in order to spread it on an electrode; the method comprising application of a difference of potential between the nozzle and an electrode; the nanofibres being formed as a result of evaporation of the solvent or mixture of solvents, due to the electrical field, and stretching of the polymer deposited on the electrode, by means of the nozzle; the nanofibres thus formed being subsequently stretched and deposited on said base fabric.

摘要： An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

摘要： , The present invention relates to an aromatherapy face mask for use ih aromatherapy and for individual protection of the upper respiratory system, providing an aromatherapy effect as well as a protective effect from the harmful components contained in the air and against infections and various pathogenic microorganisms. The aromatherapy protective mask comprising a main body and elastic loops positioned on both ends of the mask's body which has filter layers consisting of: nonwoven textile layer, woven textile layer, filter pocket, antimicrobial silver layer and aroma filter with medicinal plants where the-nonwoven textile layer (1) of the main body of the mask is the first layer, which is elastic, air-permeable, made of neoprene materials, having decorative outer layer with a middle strip (3) to which a woven textile layer (2) is sewn or glued forming a second layer, made by soft and fine woven fabric to whose lower end coinciding with the bottom part of chin of the mask user the woven textile pocket (4) made of fine fabric is positioned, covering 1/3 of the total area of the mask wherein the nonwoven textile aroma filter pre-treated with colloidal silver (5) is placed in which a compact plate of pressed selected medicinal plants and/or plant extract and/or essential oils is put. The aromatherapy protective mask according to the present Invention is a multi-layered inhalation which extracts maximal of the medicinal properties of the plants and minerals. The preliminary water-steam pre-treatment with silver water makes it antiseptic and ensures purity while achieving the desired aroma effect. The combination of different medicinal plants and / or and / or essential oils enhances the aromatherapy effect, maintains effective internal circulation of the aroma flows in the "working zone"and provides excellent medical care and natural inhalation for the user.
