Abstract
Absorbent articles comprising fibrous nits and other free-flowing particles are disclosed. In one embodiment, an absorbent article is disclosed comprising free-flowing particles in a central portion which, in conjunction with other absorbent members, provides excellent body fit and good fluid handling performance. In another embodiment, good leakage control is provided by the combined effect of good intake and fluid handling performance of fibrous nits coupled with a wicking barrier between the nits and the longitudinal sides of the articles. An optional central rising member can further enhance the topography of the article when compressed by urging the portion comprising nits to deflect vertically upward.
Methods of preparing cellulosic nits and incorporating them into absorbent articles are also described.
