Abstract
A process of impregnating fine adsorbent particles such as carbon dust or APS silica gel powder into the micro-cavities of shaped fibers comprises the steps of continuously conveying shaped fibers with micro-cavities to a reservoir of the fine adsorbent particles. The fibers pass through the reservoir to thereby produce relative motion between the fibers and the particles. Additionally, impact forces are created between the shaped fibers and the fine particles to assist in impregnating the particles into the micro-cavities of the fibers. Any excess particles are removed from the fibers outside the reservoir, and subsequently the shaped fibers impregnated with fine adsorbent particles are collected for later use in filter applications such as cigarette filter and air filter applications, for example.
