Abstract

The present invention is directed to an absorbent article with a tissue-wrapped absorbent core wherein the tissue is made from a specifically designed thermoplastic fibrous nonwoven web which is particularly well-suited to trapping and retaining particulate material such as superabsorbent particles. The invention has particular application in conjunction with personal care products such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like.
