    • A method for making a dispersible nonwoven sheet generally comprises dispersing natural fibers and regenerated fibers in a ratio of about 70 to about 90 percent by weight natural fibers and about 10 to about 30 percent by weight regenerated fibers in a liquid medium to form a liquid suspension. The liquid suspension is deposited over a foraminous forming wire to form a nonwoven tissue web. The nonwoven tissue web is sprayed with a first plurality of jets. Each jet of the first plurality of jets is spaced from an adjacent one of the first plurality of jets by a first distance. The nonwoven tissue web also is sprayed with a second plurality of jets. Each jet of the second plurality of jets is spaced from an adjacent one of the second plurality of jets by a second distance, and the second distance is less than the first distance. The nonwoven tissue web is dried to form the dispersible nonwoven sheet.
    • 制备可分散的非织造片材的方法通常包括将天然纤维和再生纤维以约70-约90重量%天然纤维和约10-约30重量%再生纤维在液体介质中的比例分散以形成液体悬浮液 。 将液体悬浮液沉积在多孔成形网上以形成非织造织物网。 用第一多个射流喷射非织造薄纸网。 第一多个射流中的每个射流与第一多个射流中的相邻一个间隔开第一距离。 非织造薄纸网幅也喷射第二多个射流。 第二多个喷口中的每个喷口与第二多个喷口中的相邻喷口间隔第二距离,并且第二距离小于第一距离。 将非织造薄纸网干燥以形成可分散的非织造薄片。
