  • Patent number: 7189888
    Abstract: This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.

  • 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.
