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 upwards. Methods of preparing cellulosic nits and incorporating them into absorbent articles are also described. Cette invention a trait à des articles absorbants comportant des noeuds fibreux et d'autres particules fluides. Dans une réalisation, l'article absorbant renferme des particules fluides dans sa partie centrale qui, en association avec d'autres éléments absorbants, épouse au mieux l'anatomie du porteur et assure une bonne réception des matières fluides. Dans une autre réalisation, l'effet combiné d'une bonne réception et d'une bonne rétention des matières fluides par les noeuds fibreux couplés à un tissu mèche constituant une barrière entre lesdits noeuds et les côtés longitudinaux de l'article absorbant permet d'éviter les fuites. Eventuellement, un élément central ascendant peut renforcer encore le profil de l'article absorbant lorsque il est comprimé et ce, en forçant la partie renfermant les noeuds à se dévier verticalement vers le haut. L'invention concerne également des procédés de préparation de noeuds cellulosiques et d'incorporation de ceux-ci à des articles absorbants.
