    摘要: A method for producing an electret filter element according to one of the preceding claims, comprising the steps: providing fibers (6), providing a spraying device (1) for a fluid, producing a spray cloud (3) of electrically charged fluid droplets (4), guiding the fibers (6) through the spray cloud (3), wetting the fibers (6) with the fluid droplets (4) and depositing the fibers (6) to form a fiber layer (8), is characterized, with regard to the problem of creating a filter element which has a homogeneous charge distribution and a high filter efficiency while being cost-effective to produce, in that the fluid droplets (4) are electrically charged by an electrical field between breakaway fluid droplets (4a) and a counter electrode (5). An electret filter element is produced according to the method.

    摘要: High absorbency lyocell fibers are obtainable by hydrothermal treatment. The fibers can be treated with water at temperatures of at least about 60° C to provice lyocell fibers that can be formed into a random fibrous plug having a mass of 2 g, a density of 4 g/cm 3 , and a diameter of 25 mm which has a GAT Absorbency (at 15 min.) of at least about 3.7 g/g.

    摘要: A method of manufacturing an electret processed product, comprising the steps of allowing a suction nozzle (22) to come into contact with a nonconductive fiber sheet (S) so as to cross in the lateral direction of the sheet while running the sheet, allowing the surface of the sheet on the opposite side of the contact part to come into contact with or to immerse into a water surface, sucking water from the suction nozzle (22) so that the water can be passed through the sheet in the thickness direction of the sheet to penetrate the water into the nonconductive fiber sheet (S), and drying the nonconductive fiber sheet (S), whereby a high quality and high performance electret processed product can be manufactured at a low cost.
