摘要： An absorbent material for use in a disposable absorbent product exhibiting enhanced wet strength characteristics includes a blend of cellulosic fibrous material and superabsorbent polymeric material, with a wax applied to the blend in a preferably discontinuous or non-uniform distribution for enhancing wet strength characteristics of the material, without unacceptably diminishing its absorbency. Notably, the absorbent material includes regions of relatively high densification, which can exist about particles of superabsorbent material, with application of wax in a molten form resulting in the spontaneous flow and migration of the wax to the regions of higher densification. The material can be formed with a pattern of regions of relatively high and low densification, with the wax preferentially distributed in those regions of high densification. It is believed that the wax acts to maintain the strength of hydrogen bonds formed within the absorbent material, by minimizing the effect of wetting the bonds when liquid is absorbed by the structure.
