Abstract
The present invention is directed to hygiene articles comprising nanofibers. The nanofibers are made from a melt film fibrillation process with a polymer composition having a melt flow rate of less than about 400 decigram per minute. 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 hygiene articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, and feminine wipes.
