摘要： An air filter material for intercepting dust is disclosed. The material is free of lubricants and antistatic agents, and consists of a blend of (I) polyolefin fibers and (II) polyacrylonitrile fibers that are geometrically stable. The fibers (I) are two-component polypropylene/polyethylene fibers of the core/jacket or side-by-side type, and fibers (II) are halogen-free. The fiber blend is washed during the manufacturing process after they are first combined.

摘要： An adsorption air filter has a self-supporting shaped structure of adsorber particles of regular or irregular form, which are joined to one another by binder particles also of regular or irregular form. The melting range of the binder particles is less than that of the adsorber particles, and the binder particles are smaller than the adsorber particles. The adsorber particles have an average size of 100 to 7000 .mu.m. The three-dimensional structure of the air filter has substantially repeating units of one adsorber particle and one binder particle, without the presence of agglomerates. The binder must not spread over the adsorber surface below 100.degree. C. In the production method, adsorber and binder particles are mixed with water and heated in a closed mold under pressure; the water is then driven off and the shaped element is allowed to cool.

摘要： An adsorbent, supple, filter fabric composed of an air-permeable, supple, textile, carrier material having adsorbent particles fixed on it by means of a thermoplastic binding agent. The adsorbent particles are coated on their surface with binding-agent particles which are set apart from each other. The average diameter of the binding-agent particles is smaller than that of the adsorbent particles. The adsorbent particles are also bonded to each other by binding-agent particles. The coating of the carrier material with adsorbent material is over 200 g/m.sup.2. The fabric has a total thickness of 0.5 to 5 mm, and its suppleness permits a bending radius of not more than 5 mm able to be carried out free of destruction. The filter fabric is manufactured by first mixing absorbent and binding-agent particles while adding water. The mixing is followed by carrying out the following steps in continuous sequence: sprinkling of the mixture on the textile carrier material, heating above the start of melting of the binding agent, and cooling off and rolling up of the resultant supple filter fabric. The product can be used in air purification systems as well as for protective clothing.
