The nanometer composite nanofiber layer includes first, second, and third nano-powder composite nanofibers, which are uniformly mixed by means of an airflow or are sequentially laminated to form the nanometer composite nanofiber layer. The nanometer composite nanofiber layer formed through sequential lamination includes first, second, and third nanofiber layers. The first nanofiber layer includes multiple first nano-powder composite nanofibers. The second nanofiber layer is stacked on the first nanofiber layer and includes multiple second nano-powder composite nanofibers. The third nanofiber layer is stacked on the second nanofiber layer and includes multiple third nano-powder composite nanofibers. The composite nanofiber filtration layer is formed of multiple nanometer composite nanofiber layers, so that the high-adsorption-performance nanofiber air filter medium shows improved performance.

A non-woven fabric composite and an article including the same are provided. The non-woven fabric includes an electrostatically treated meltblown non-woven fabric layer and a spunbond non-woven fabric layer on one or both sides thereof, and has a fine dust removal performance retention ratio, represented by Equation 1, of 80% or more:

Fine dust removal performance retention ratio (%)=(fine dust removal efficiency after accelerated aging treatment)/(fine dust removal efficiency before accelerated aging treatment)×100  [Equation 1]

wherein, in this equation, the fine dust is an aerosol containing sodium chloride dispersed in air, and the accelerated aging treatment refers to a case where the non-woven fabric composite is stored at a temperature of 70° C. for 3 days.

Nonwoven fabrics are provided that include a first meltblown layer, in which the first meltblown layer comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives. The first polymer component comprises a first recycled-polypropylene (rPP).

A spunbond nonwoven fabric, comprising fibers of a propylene-based polymer composition containing 100 parts by mass of a propylene-based polymer (A) and 1 part by mass to 10 parts by mass of an ethylene-based polymer (B) having a density of from 0.93 g/cm.sup.3 to 0.98 g/cm.sup.3, wherein air permeability measured in accordance with JIS L 1096 (2010) by a Frazier type air permeability tester at a flow rate corresponding to a pressure differential of 125 Pa is 500 cm.sup.3/cm.sup.2/s or less.

A disposable face mask includes an upper portion of the face mask and a lower portion of the face mask, the upper portion and lower portion of the face masks each adjoin monolithically formed therewith face mask straps defined by perforations in a web of material used to form the face mask and straps, wherein the perforations allow the straps to be partially separated and utilized for securing said face mask to a wearer's face. The disposable face mask may be made by perforating patterns into a web of materials to define the face mask straps and face mask body that are formed monolithically from the web of materials. The face masks may be wound on a roll for dispensing by tearing off from the roll and then separating the straps at the perforations. Alternatively, the face mask borders may be cut-through to allow dispensing of the face masks individually from bulk packaging, where the face mask is removed from the package and the straps are separated at the perforations to allow the face mask to be secured to the wearer's face by tying the straps behind the wearer's head.

A nonwoven fabric layered body includes a first nonwoven fabric layer including a crimped fiber (A), which is a fiber made of a thermoplastic polymer and which has an average crimp diameter of 800 μm or less; and a hydrophilic agent.

The present invention relates to a positively charged filter material with excellent ability for removing charged particles efficiently, and a method for producing the same, and more specifically to a positively charged filter material having the ability to selectively remove efficiently, in water, negatively charged organic/inorganic particles, heavy metal ions and pathogenic microorganisms, and a method for producing the same.
