摘要： A filtration material comprising a blend of polypropylene and acrylic fibers of round, flat, dog bone, oval or kidney bean shape in any size from 0.08 to 3.3 Dtex. A preferred blend contains about 50 weight percent polypropylene fibers and about 50 weight percent acrylic fibers. The fibers can be blended ranging from 90:10 to 10:90 polypropylene to acrylic. The shape contains 25 weight percent round, flat, oval, dog bone and kidney bean shapes. The fiber blend contains 25 weight percent of at least one size between 0.08 and 3.3 Dtex. Electret fibers incorporated within these blends have 0.02 to 33 weight percent of a charge control agent. These fibers can be used in producing electret material by corona or triboelectric charging methods.

摘要： Provided is an electret having high piezoelectric properties. An electret sheet of the invention is characterized in that it comprises a synthetic resin sheet is electrified by injecting electric charges thereinto, that the synthetic resin sheet comprises two types of synthetic resins incompatible with each other, and that these synthetic resins form a phase separated structure and are cross-linked through a polyfunctional monomer. Therefore, positive and negative charges in an apparently polarized state are present in the interfacial portions between the two types of synthetic resins incompatible with each other. By applying an external force to the electret sheet to deform it, the relative positions of these positive and negative charges are changed, and these changes cause a favorable electrical response. Therefore, the electret sheet has high piezoelectric properties.

摘要： A cylindrical or other suitably shaped filter container for insertion into a user's nares to filter inhaled air to remove airborne items. The filter container has two open ends forming a container surrounding filter material. Polypropylene may be used to form the container or tube. Other suitable material such as rubber or other softer material may also be used. The present disclosure further includes a respiration mask having a peripheral seal composed of treated and fluffed polypropylene fibers. An edge seal according to the present disclosure lowers the respiratory resistance of a mask and improves the filtration efficiency. Treated, fluffed, polypropylene may also be used to form a respiration mask, such a mask may also include an edge seal to improve filtration and comfort. Treated, meltblown, polypropylene may also be used to form a filter napkin or handkerchief that may be carried and used in short term or unexpected situations.

C. into shaped elements having very narrow channels through which the gas stream flows, wherein the shaped elements are of a material that becomes conductive at high temperatures and further includes the step of selecting the width of the narrow channels based on the gas stream velocity such that turbulence is generated along the flow path causing the liquid drops to strike the channel walls and deposit thereon. The apparatus for separating liquid drops from a gas stream includes a plurality of shaped elements having very narrow channels through which the gas stream having a temperature greater than 600.degree. C. flows, the shaped elements combined to a compound structure and are of a material that becomes conductive at high temperatures and the channels having a width based upon the gas stream velocity to effect turbulence along the flow path causing the liquid drops to strike the channel walls and deposit thereon.
