摘要： There is provided a vacuum cleaner filter medium which is a nonwoven spunbond web of conjugate spunbond fibers. The web has a Frazier permeability of at least 250 CFM, an NaCI efficiency of at least 65 percent, a Gurley Stiffness of at least 20 mg, and a pressure drop of 0.5 or less mm H.sub.2 O. The conjugate fibers are made from polymers, more particularly polyolefins, still more particularly polypropylene and polyethylene in a side-by-side configuration. The filter medium is treated by a hot-air knife and through-air bonded during the production process. The medium is also electret treated. The medium has sufficient stiffness to be converted into a filter by conventional techniques. While this invention is directed mainly to air purification and filtration, other gasses may be filtered as well.

摘要： A nonwoven filamentary web having high loft is produced by extruding a molten thermoplastic polymer or polymer blend through a spinneret to form continuous filaments while maintaining extrusion conditions which induce melt-fracture of the extrudate; attenuating the thus extruded melt-fractured filaments to obtain filamentary material having a crimped structure; and depositing the melt-fractured filamentary material on a collection surface and forming a web therefrom.

摘要： An apparatus and method for removing particles from refinery fluid hydrocarbon and organic streams comprising an elongated housing containing multiple layers of non-woven fabric arranged in said housing as discrete stratified layer array of filter fabric of increasing particle retentive power thus arranged in the housing in the direction of fluid flow. The fabric layer comprise thermally stable materials of different permeability which are mineral coated to provide structural, fluid compression resistance, and to which flint or talc particles are added to impact surface roughness to the fibers. A final layer of uncoated needled felt fine fabrics end caps the array. In operation the refinery fluid is passed through the filter array such that the direction of fluid flow is in the direction of increasing retentive power of the filter fabric array. The use of fabrics rather than particle beds permits the use of separation units of vertical upflow configurations in which gravity assists in particle retention and removal.
