    • A filter and method for applying differential levels of active ingredient materials to specific areas of filters, such as the filter paper used to make disposable vacuum cleaner bags, so as to cause the effluent such as air which has passed through such filters to sustainably act as a dispersing agent for such filter-impregnated active ingredients as may condition the effluent which has passed through the filter in ways that are desirable to the user of the filter. The active ingredients are unevenly distributed on the filter substrate in a pattern determined by predicted changing flow rate patterns through the area of the substrate during intervals of increasing accumulation of particulate matter against the filter and effective to maximally sustain dispersion of active ingredient during such intervals.
    • 一种过滤器和方法,用于将不同程度的活性成分材料施加到过滤器的特定区域,例如用于制造一次性吸尘器袋的滤纸,以便使已经通过这种过滤器的流出物可持续地作为 用于这种过滤器浸渍的活性成分的分散剂,可以调节已经通过过滤器的流出物,其方式对过滤器的使用者是期望的。 活性成分以过滤颗粒物质相对于过滤器的积累增加的间隔期间通过基板区域预测的变化的流速图案确定的图案不均匀地分布在过滤器基底上,并有效地在这样的间隔期间最大限度地维持活性成分的分散。
