Abstract
Polyethylene glycol is used as a binder material for fibers, such as wood pulp fibers, and for adhering superabsorbent particulate materials to the fibers.
Claims29
A fiber product which comprises discontinuous fibers having a polyethylene glycol binder material on at least a portion of the fibers and superabsorbent particulate material adhered to the fibers in particulate form by the binder material.
A product according to claim i in which the discontinuous fibers comprise cellulosic fibers.
A fiber product which comprises discontinuous fibers having a polyethylene glycol binder material on at least a portion of the fibers and superabsorbent particulate material adhered to the fibers in particulate form by the binder material without the particulate material being covered by the binder material, and discontinuous fibers having a second binder other than polyethylene glycol on at least a portion of the surface of such fibers.
A fiber product which comprises discontinuous fibers, at least a substantial majority of the fibers having at least a substantial majority of their surfaces continuously coated with a polyethylene glycol binder material, the binder material being present in an amount which is at least about seven percent of the binder material and fibers, and a substantial majority of the fibers being unbonded.
A fiber product which comprises discontinuous fibers, at least a substantial majority of the fibers having at least a substantial majority of their surfaces continuously coated with a polyethylene glycol binder material, the binder material being present in an amount which is at least about seven percent of the binder material and fibers, a substantial majority of the fibers being unbonded, and including discontinuous fibers having a second binder other than polyethylene glycol on at least a portion of the surface of such fibers.
A fiber product which comprises wood pulp fibers, a polyethylene glycol binder material on at least a portion of the surface of the wood pulp fibers, wherein a substantial majority of the wood pulp fibers are unbonded to each other.
A fiber product which comprises wood pulp fibers, a polyethylene glycol binder material on at least a portion of the surface of the wood pulp fibers, and superabsorbent particulate material adhered to the wood pulp fibers in particulate form by the binder material.
A fiber product which comprises wood pulp fibers, a polyethylene glycol binder material on at least a portion of the surface of the wood pulp fibers, superabsorbent particulate material adhered to the wood pulp fibers in particulate form by the binder material, and discontinuous fibers having a second binder other than polyethylene glycol on at least a portion of the surface of the discontinuous fibers.
A fiber product according to claim, 28 in which the additional discontinuous fibers comprise wood pulp fibers.
