Nanofiber Filter Facemasks and Cabin Filters

Inventor Wallace Woon-Fong Leung Patent Name Nanofiber Filter Facemasks and Cabin Filters (USA – US 8303693) 纳米纤维过滤面罩和舱室过滤器 (China – CN 104043286) 納米纖維過濾面罩和艙室過濾器 (HongKong – HK 1201777)   Abstract A filtration medium includes a fine filter layer having a plurality of nanofibers and a coarse filter layer having a plurality of micro fibers attached to the[…]

Static Fabrics and Nanofiber Composites

Material Property It’s a composite from production of “dry-laid nonwoven fabric” as main substrate together with nanofibers. Micro dusts can be intercepted by the static electricity of “dry-laid nonwoven fabric” and deposit on the surface of the fibers. After composition with nanofibers, the filtration efficiency is increased and the filter usage life is extended. Thicker[…]

Meltblown Fabrics and Nanofiber Composites

Material Property It’s a composite material using “meltblown” as main substrate together with nanofibers. The first layer is “meltblown” for the purpose of pre-filtering and to improve the volume of dust capacity. The “nanofiber layer” is to enhance the overall filtration efficiency. The composite filter can fully meet the requirements of air filtration performance. The[…]

Anti-Bacterial Nanofiber

Functionality This nanofiber itself possesses anti-bacteria property. It is produced from special-made solvent contains charged ions with antibacterial function to reduce and inhibit the growth and reproduction of the microorganisms on the fabric. In addition, the anti-bacterial nanofiber can prevent the fabric from microbial infection, mold, deterioration and transmission of infectious diseases. Applications Textiles, masks,[…]
