SCHMELZGEBLASENE MIKROFASERN AUS IONOMEREN UND DARAUS HERGESTELLTE VLIESSTOFFE FÜR GASFILTER |
| 摘要 |
<p>Ethylene/carboxylic acid ionomers may be made, using a meltspun, and particularly meltblown process, into microfibers and thence to filter webs which are efficient gas filters for removing particles having a diameter of from 0.5 to 20 microns from a gas. The webs are effective without a deliberate specific post-charging operation during production. A deliberate post-charging operation can also be carried out to result in further efficiency.</p> |
