    摘要： An absorbent elastic nonwoven material having improved conformability includes a matrix of thermoplastic elastomeric nonwoven filaments, present in an amount of about 3 to less than 20% by weight of the absorbent elastic nonwoven material. A plurality of absorbent fibers and a superabsorbent material are contained within the matrix, each constituting about 20-77% by weight of the absorbent elastic nonwoven material. The absorbent elastic nonwoven material is useful in a wide variety of personal care and medical absorbent articles where softness and conformability, as well as absorbency and elasticity, are important.

    摘要： An absorbent article (10) has a longitudinal direction (26), a lateral, transverse direction (24), an article front portion (14), an article back portion (12), and an intermediate portion (16) interconnecting the front and back portions. The article includes an elastomerically stretchable backsheet member (30), a liquid-permeable topsheet layer (28), and an elastomerically stretchable retention portion (48) sandwiched between the backsheet member (30) and the topsheet layer (28). The topsheet layer can be elastomerically stretchable, and the absorbent article (10) can also provide a selected combination of physical properties, such as a composite-article elongation-at-peak-load value which is at least about 50 percent.

    摘要： A coated porous substrate composed of a hydrophobic polymer which is substantially uniformly coated with a hydrophilic polymeric material. The substrate may be a sheet-like material, examples of which are foams, fibers, and fibrous webs. The fibrous webs desirably will be nonwoven webs. The coating on the substrate is durable to an aqueous medium at a temperature in a range of from about 10.degree. C. to about 50.degree. C. and does not significantly suppress the surface tension of an aqueous medium with which the coated substrate may come in contact. The hydrophobic polymer may be a polyolefin, such as polyethylene or polypropylene. The hydrophilic polymeric material with which the polymer fibers are coated may be a polysaccharide or a modified polysaccharide. Also provided is a method of preparing a coated porous substrate which involves providing a porous substrate composed of a hydrophobic polymer. At least a portion of the substrate then is exposed to a field of reactive species. At least a portion of the porous substrate, including the portion exposed to the reactive species, is treated with a mixture which includes water and a hydrophilic polymeric material under conditions sufficient to substantially uniformly coat the porous substrate with the hydrophilic polymeric material.
