The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g/3″ and high bulk, such as sheet bulks greater than about 10 cc/g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.

Tissue products comprising crosslinked fibers

An absorbent structure made at least in part from a superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least 575&#xd7;10cm. In another embodiment, the absorbent structure is made at least in part from a superabsorbent material having a retention capacity (CRC) as determined by a Centrifuge Retention Capacity Test of at least about 25 g/g, an absorbency under load (AUL) at 0.9 psi as determined by an Absorbency Under Load Test of at least 18 and a free swell gel bed permeability (GBP) as determined by a Free Swell Gel Bed Permeability Test of at least about 350&#xd7;10cm.

Absorbent structure with superabsorbent material

An absorbent structure can include a matrix of fibers, wherein the matrix is reinforced with a reinforcing member, such as scrim. Preferably, the scrim is secured to the fibrous matrix by entanglement of fibers with the scrim and entanglement of fibers in the matrix from opposite sides of the scrim with each other. The scrim layer can be restricted to a longitudinally extending, medial region of the absorbent. In a particular arrangement, the scrim has a cross-directional width dimension which is less than a narrowest width dimension of the fibrous matrix. The scrim can be located between two, opposed, major surfaces of the fibrous matrix.

Superabsorbent material treated to resist damage when subjected to an Absorbent Product Processing Simulation Test, which simulates the mechanical damage that occurs during current commercial diaper manufacturing processes. The treated superabsorbent material has a centrifuge retention capacity of about 15 grams or greater of 0.9 weight percent sodium chloride per gram of the superabsorbent material and a gel bed permeability (GBP) at 0 psi swell pressure on pre-screened particles of about 200 (&#xd7;10cm) or greater. After subjecting the treated superabsorbent material to the Absorbent Product Processing Simulation Test, the treated superabsorbent may exhibit minimal reduction in GBP of pre-screened or un-screened particles at 0 psi or at 0.3 psi swell pressure, as well as possibly exhibiting minimal reduction in average particle size diameter (PSD). The superabsorbent material can be treated by adding an aqueous solution of a hydrophilic soft polymer to the superabsorbent material, mixing the superabsorbent material with the aqueous solution, and drying the superabsorbent material.

Damage-resistant superabsorbent materials

A disposable absorbent garment has a front region, a back region, and a central region, each region having a length along a longitudinal axis of one third of the length of the absorbent garment. An absorbent pad positioned within the regions has a length of absorbent pad in the back region divided by a length of absorbent pad in the front region and central region less than 0.10, and the length in the front region is greater than the length in the back region.

Absorbent articles of the present invention are specifically adapted for the adult male anatomy. The articles include a moisture barrier, a liner bonded to the moisture barrier, and an absorbent assembly sandwiched therebetween. The moisture barrier is gathered along each of its side edges between forward and rearward terminal points. The moisture barrier is gathered along its back end by an elasticized back pouch member. The back pouch member includes a flange section and a pouch section. The pouch section includes a substantially fixed edge portion, an elasticized gathered movable edge portion, a substantially liquid impermeable pouch barrier layer, a pouch fabric layer, and a plurality of separate laterally extending pouch elastic members sandwiched between the pouch barrier layer and the pouch fabric layer. In particular embodiments, a retaining member is bonded to the liner and defines therebetween a compartment having a volume, and a cover formed of a liquid impermeable material is bonded to the liner.

An apparatus for forming a substantially uniform distribution of particulate material within the cross direction of a fibrous web includes a conveying mechanism for providing a gas entrained supply of the particulate material. A transferring mechanism directs the particulate into a delivery gas stream to provide a flow volume of the particulate material a delivery conduit and a delivery nozzle into a web forming chamber. A fiberizing mechanism provides a flow of a selected fibrous material into the web forming chamber, and a directing mechanism controls the flow of particulate material from the delivery conduit and the delivery nozzle into the web forming chamber. A foraminous forming layer is disposed within the web forming chamber for receiving the fibrous material and the particulate material to produce a fibrous web which includes a substantially uniform distribution in the cross direction of the particulate material therein.
