Abstract
A highly absorbent, flexible and resilient sheet comprising a non-defiberized cellulosic pulp board containing effective amounts of debonding agent and cross-linked cellulosic fibers, well-suited for use as an absorbent component of a disposable, absorbent product such as a sanitary napkin, a diaper, an incontinence pad, an adult brief, a wound dressing and the like. The invention also extends to a method for manufacturing the fluid-absorbent sheet, to a disposable absorbent product utilizing the fluid-absorbent sheet and to a method for enhancing the resilience, fluid-absorbency and flexibility of a non-defiberized cellulosic pulp board.
Claims8
A disposable, laminated fluid-absorbent product comprising:
- a) a fluid-permeable cover layer;
- b) a fluid-impervious backing layer in a generally parallel and spaced apart relationship with said fluid permeable cover layer;
- and
- c) an absorbent component between said layers, said absorbent component comprising a non-defiberized cellulosic pulp board containing a debonding agent and cross-linked cellulosic fibers said cross-linked cellulosic fibers having been formed by treating noncross-linked cellulosic fibers with a glycol having a formula HO--(CH.sub.2).sub.m O).sub.n --H where m is 2 or 3 and n is in the range 1 to 500, and a dialdehyde having a formula OCH(CHX).sub.n --CHO wherein n is in the range 0 to 4 and X is hydrogen of hydroxyl, and wherein the debonding agent and the cross-linked cellulosic fibers are present in an amount effective to enhance the flexibility and fluid penetration of the absorbent component.
