摘要： 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.

摘要： 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 (×10−9 cm2) 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.
