摘要： An electret fiber sheet has polarized charges on its surface and preferably has charges in ordered orientation across it. The polarized charges are present in an amount of at least 7 × 10 -11 C/cm 2 . Such sheets are found to have a high dust collecting efficiency. Sheets having an amount of polarized charge even as high as this are nevertheless stable when they have a maximum activation energy of depolarization of at least 0.2 eV. Such an electret sheet can be obtained by a process comprising placing a fiber sheet between a non-contact type voltage-application electrode and an earth electrode confronting each other and supplying electricity (voltage > 3 kV; current density > 1 x 10 -6 mA/cm 2 ) between the electrodes, provided that the fiber sheet has a weight no more than 80 g/m 2 and a covering factor of at least 60%. The electret fiber sheets are useful in a variety of applications, such as filter materials, especially for collection of micro dust; clothing and furniture apparel for industrial clean rooms; adsorbing materials; and medical materials such as masks and collectors of bacilli.

摘要： Disclosed is a high-performance electret comprising 60 to 99% by weight of a non-polar polymer, 0.5 to 39.5% by weight of a polar polymer and 0.5 to 20% by weight of at least one component selected from the group consisting of (A) a non-polar polymer modified with an unsaturated carboxylic acid or a derivative thereof, (B) a non-polar polymer modified with an unsaturated epoxy monomer and (C) a non-polar polymer modified with a silane monomer having an olefinically unsaturated bond.
In this electret, a high charge density can be maintained stably over a long period, and this electret can be easily formed into a film. An air filter prepared from this electret is very excellent in the dust collecting efficiency.

摘要： Le procédé de l'invention réside en ce qu'on lisse la ou les surfaces pelucheuses de ladite couche en exerçant une friction légère sous faible pression afin que les fibres saillantes soient couchées sur la masse fibreuse sous-jacente sans que celle-ci soit comprimée, la friction étant exercée à une température de ramollissement telle que les fibres superficielles se soudent entre elles pour former une peau ou glacis poreux. De préférence, le lissage est effectué au moyen d'une mass métallique dont la température est comprise entre 115 et 150°C.
Ce procédé peut s'appliquer à la face extérieure d'un masque respiratoire filtrant constitué par une enveloppe en ce matériau fibreux recouvrant une coquille poreuse relativement rigide pour la protection de la peau ; il peut également s'appliquer à l'une au moins des faces de couches filtrantes équipant des filtres quelconques.

摘要： The invention permits, without the consumption of energy, emission of negative ions to purify the environment. In addition, the invention has biocidal action to eliminate microorganisms and bacteria. Furthermore, the invention emits infrared radiation to dry out walls, ceilings and objects in the room, thereby removing moisture. To those ends, the invention comprises a frame (1, 2) and a first body (3) that emits negative ions, which comprises a first anodized aluminium plate (7) and a second anodized aluminium plate (8), which are covered with a ceramic paint with silver-doped zeolites, which, in addition to emitting negative ions, constitutes a nanosilver-based biocidal compound. Said aluminium plates (7, 8) are heated uniformly by a wire (6) in order to emit infra-red radiation

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.
