| 摘要 |
<p>The invention provides a novel method of preparing a filter media by thermally bonding silver-coated nanofiber fabrics to a dirt-retaining membrane, a chemical-retaining membrane, a pathogen-retaining membrane, or a combination thereof. The invention also relates to the use of silver-coated nanofiber fabric layer as a component of a microorganism-killing membrane in filter media for a liquid or air filtration system. The filter of the invention offers efficient disinfection effects, maintaining a low pressure drop and a high flow rate when in use. Further, the filter media is adhesive-layer free and contains contains least one thermal binding layer made of spunbonded nonwoven polymeric system. The invention also features a water-purification cartridge and a portable water system thereof.</p> |
