  • Patent number: 5403870
    Abstract: A porous structure of a water-swellable, water-insoluble polymeric material which porous structure possesses improved free swell capacity and is able to demonstrate said improved free swell capacity when in contact with an absorbent material such as a cellulosic fibrous web. Also disclosed is a method of making such a porous polymeric structure. The method comprising the steps of forming an oil-in-water suspension, wherein the water phase contains a water-soluble monomer and a crosslinking agent and the oil phase is a volatile organic compound having a boiling point greater than the boiling point of water. The monomer present in the water phase is polymerized to form a polymeric material having dispersed therein the oil phase. The resultant polymeric material is then dried at a temperature above the boiling point of water, such that the volatile organic compound volatilizes thereby forming pores in the polymeric material, which pores have a diameter of at least about 20 microns.

  • Patent number: 5401267
    Abstract: An absorbent article is disclosed which exhibits enhanced wicking capacity. The absorbent article includes a liquid-permeable cover, a liquid-impermeable baffle and an absorbent enclosed therebetween. The absorbent is constructed of first, second and third members. Each member has a wicking capacity for body fluids discharged by a human body. The first member has a high wicking capacity, the second member has a lower wicking capacity than the first member, and the third member has a greater wicking capacity than the second member. The different wicking capacities of the three members promotes a systematic distribution of body fluid away from the body-side cover down into the absorbent article. The second member also has an equal or greater width than either the first or third members so as to provide a visual cue of when the absorbent article is in need of changing.

A selected fastening means, such as a layer of primary adhesive (54), is positioned and applied onto a major facing surface (186) of the substrate web (140). A first longitudinally extending web of stiffening material (154) is attached to the major surface of the substrate web (140) at a location which is proximate a first side edge region (142) of the substrate web. A second longitudinally extending web of stiffening material (156) is attached to the major surface of the substrate web (140) at a location which is proximate the second side edge region (144) of the substrate web (140).

  • Patent number: 5397625
    Abstract: Disclosed herein is a duo-functional nonwoven composite having a support layer with a top surface and a bottom surface separated by a thickness. On the bottom surface of the support layer is a fibrous nonwoven web with all or a portion of the fibers being formed from a material which is soluble in a fluid such as water. At least a portion of the fibers extend through the thickness of the support layer from the bottom surface and project beyond the top surface to give the top surface a cloth-like appearance. Upon wetting the top surface of the support layer by a fluid such as water, urine or menses, the soluble fibers begin to shrink and dissolve until all or a portion of the filaments have retracted back into and through the thickness of the support layer. In so doing, the applied fluid is transported substantially away from the top surface of the composite.

  • Patent number: 5395308
    Abstract: A thermoplastic applicator is disclosed which exhibits accelerated breakup when immersed in water. The applicator includes a hollow, cylindrically shaped member which holds a pledget. This cylindrically shaped member is constructed of a water-soluble or water-dispersible material and has a wall with a thickness of less than about 0.05 inches (about 12.7 mm). A plurality of grooves are formed in the wail in a predetermined pattern to accelerate breakup of the applicator into small unrecognizable pieces, The grooves have a depth of between about 5 percent to 75 percent of the thickness of the wall. The deeper the grooves, the shorter the time period needed to breakup the applicator.

  • Patent number: 5392590
    Abstract: The invention provides a method for reducing or eliminating the odors commonly produced by the sterilization of polyolefin-based products by gamma radiation. In addition, the invention also provides a method for minimizing the amount of fabric strength loss associated with the irradiation process and a method for actually increasing the fabric strength of a polyethylene that has been irradiated. Both the reduction in odors and the minimization of strength or increase in polyolefin strength are achieved in methods comprising the use of an oxygen scavenger. The invention further includes the use of non-gamma stabilized polyolefins. The polyolefinic product may also include an odor mask that may be used to mask any residual odor.
