Continuous process for retaining solid adsorbent particles on shaped micro-cavity fibers |
摘要 |
A process of retaining fine adsorbent particles such as carbon material or APS silica gel in the micro-cavities of a shaped fiber comprises the steps of continuously conveying a shaped fiber with micro-cavities to a charging arrangement where the fiber is electrostatically charged. The electrostatically charged fiber is then drawn through a reservoir of the fine adsorbent particles. As the fiber passes through the reservoir the fine particles adhere to the fiber and the micro-cavities thereof. Any excess particles are removed from the fiber outside the reservoir. Subsequently the shaped fiber loaded with fine adsorbent particles is collected for use in filter applications of one type or another such as cigarette filters, for example.
