Absorbent composites containing particles of absorbent gelling material and chemically stiffened, cellulosic fibers, the fibers being wrapped around and adhered to the particles, which are in individual form. The chemically stiffened, cellulosic fibers are preferably cellulosic fibers in substantially individual form having a crosslinking agent reacted with the fibers in intrafiber crosslink bond form. The absorbent composites are particularly suitable for use in the absorbent core of disposable absorbent articles such as sanitary napkins and diapers.
Composites absorbants renfermant des particules de matériau gélifiant absorbant et des fibres cellulosiques rigidifiées chimiquement, lesdites fibres étant enroulées autour des particules et collées à celles-ci, les particules étant séparées. Les fibres cellulosiques rigidifiées chimiquement sont de préférence des fibres cellulosiques sensiblement séparées contenant un agent de réticulation que l'on a fait réagir avec les fibres pour former une liaison réticulée intrafibre. Les composites absorbants sont particulièrement adaptés pour être utilisés dans le noyau absorbant d'articles absorbants jetables tels que des serviettes hygiéniques et des couches.
