A hygiene article including a nonwoven web having nanofibers. The hygiene articles include diapers, training pants, adult incontinence pads, catamenials products, tampons, personal cleansing articles, and personal care articles. The nanofiber webs can be used as a barrier, wipe, or absorbent material. Particularly, the nanofiber web is used in a diaper as a barrier-on-core, outercover, and/or leg cuff. It may also be used as a wipe. The nanofibers, having a diameter of less than 1 micron, must comprise a significant number of the fibers in one layer of the web contained by the hygiene article. The nanofibers are produced from a melt film fibrillation process. The process generally includes the steps of providing a polymeric melt, utilizing a fluid stream to form an elongated hollow polymeric film, and using this and/or other fluid streams to form multiple nanofibers. |
