    摘要： Provided is a nonwoven material, including a spunbound layer including fibers having an average diameter between 12 and 25 microns, a meltblown layer adjacent to the spunbound layer and including fibers having an average diameter between 2 and 5 microns, and an electrospun layer adjacent to the meltblown layer and including nanofibers having an average diameter between 100 and 400 nanometers. Also provided is an electrospun layer having a basis weight of at least 0.2 gsm, the total basis weight of the meltblown layer is at least twice that of the electrospun layer, and the total basis weight of all of the meltblown layers in the material constitutes at least 3% of the basis weight of the material. Further provided is a spunbound layer that may have an average pore size between 70 and 120 microns, the meltblown layer may have an average pore size between 15 and 25 microns, and the electrospun layer may have an average pore size between 500 nanometers and 2 microns.

    摘要： The chrysanthemum-shaped element is in a cylindrical shape in which folds are formed and inner surfaces of adjacent folds are bonded at their top and bottom edges. The chrysanthemum-shaped element includes (A) an element body composed of a filter medium having a filter paper and a low-melting fiber layer formed on a surface of the filter paper on the inner surface side of the folds at least at the top and bottom edges of the filter paper; and (B) bonding sections formed at the top and bottom edges on inner surfaces of the folds by heat-adhesion of the low-melting fiber layer. The low-melting fiber layer is made of a fiber having a lower melting point than that of filter paper materials that form the filter paper and/or compound fibers which contain a fiber of a lower melting point than that of the filter paper material.

    摘要： A universal porous unit whose edges are metallic foil, or metallic foil and polymeric film laminate, or metallic foil and porous membrane, or metallic foil and polymeric film and porous membrane, held together by heat sealing and/or adhesive, or any other method to attach them, so that one or both surfaces of the laminate is/are metallic foil. Metallic foil in the rim can be on one side, the other surface being polymeric film or porous membrane. Metallic foil can be on both sides, the polymeric film or porous membrane being between the two metallic foils. The metallic foil serves to hold and conform the unit to the item to which it is applied and the diaphragm is porous for filtering, screening, or straining. The universal porous unit can be used in home, clinical, industrial, and construction settings to serve as a disposable, easy-to-use, compact, economical filtering, screening, or straining device.
