Zusammenfassung:A dispersible moist wipe includes regenerated cellulose fibers in an amount equal to or less than 20 percent by weight and natural cellulose fibers in an amount equal to or greater than 80 percent byweight. At least 50 percent of the natural cellulose fibers are fibrillated. The regenerated cellulose fibers and the natural cellulose fibers are hydroentangled such that the web has a wet CD tensilestrength of at least 200 grams per inch. A method of making a dispersible nonwoven sheet includes dispersing natural cellulose fibers and regenerated cellulose fibers in a liquid medium to form a liquid suspension and depositing the liquid suspension over a forming surface to form a nonwoven web. The natural cellulose fibers and regenerated cellulose fibers of the web are hydroentangled using a plurality of hydroentangling jets. 种可分散性湿擦拭物包含等于或低于20重量%含量的再生纤维素纤维和等于或大于80重量%含量的天然纤维素纤维。至少50%的所述天然纤维素纤维原纤化。将所述再生纤维素纤维和所述天然纤维素纤维水力缠结,以使得网具有至少200克每英寸的湿CD拉伸强度。种制备可分散性非织造片材的方法包括:将天然纤维素纤维和再生纤维素纤维在液体介质中分散以形成液体悬浮液,以及将所述液体悬浮液沉积在成型表面上以形
