Abstract

1346231 Gas filter material; electrostatic separation BAYER AG 23 June 1971 [29 June 1970] 29419/71 Headings BIT and B2J [Also in Divisions B5 and D1] A fibre filter comprises a gas permeable support layer which carries a fibre fleece, the fleece having been produced by electrostatically spraying an organic solution on to a conductive support. Apparatus for forming the fleece comprises an annular electrode 8 which rotates through a tank 7 of the organic solution. The fleece forms on belts 5 which carry a pre-placed coarse backing material and which are charged oppositely to the electrode 8. The polarity of the electrodes may be alternated to give an alternating residual charge in successive layers of the formed fleece which enhances the dust catching properties of the filter. Two fleeces formed as described above may be combined to provide a reinforcing layer on both outside surfaces. Examples of suitable organic polymers and solvents are given.
