Abstract:
A method of binding superabsorbent particles to cellulose fibers with a nonpolymeric binder, comprising the steps of:providing cellulose fibers having a hydrogen bonding functionality; providing superabsorbent particles having a hydrogen bonding or a coordinate covalent bond forming functionality that have a nonpolymeric binder comprising propylene glycol applied thereto in the absence of the cellulose fibers, the propylene glycol being present on the superabsorbent particles in an amount from about 0.01 to 5.0% by weight based on the weight of the superabsorbent particles and being in an inactive state; activating the binder on the superabsorbent particles by providing heat to the superabsorbent particle; and binding at least a portion of the superabsorbent particles in particulate form carrying the activated binder to the cellulose fibers.
