  • 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.

  • Publication number: 20070036972
    Abstract: Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.

  • Publication number: 20060269748
    Abstract: Extensible bicomponent fibers and webs particularly adapted for disposable personal care product component applications. Sheath/core configurations providing desirable feel properties for elastic embodiments when compared with conventional elastic fibers and webs are obtained with specific olefin polymer combinations and sheath configurations.
