    摘要： A latent elastic laminate material, and methods of making latent elastic laminate materials. The laminate includes a latent polymer, which itself may or may not possess latent elasticity, that is applied to at least one elastic member while the elastic member is in a stretched configuration. The elastic member, at least partially covered with the latent polymer, is attached to at least one substrate. The amount of latent polymer applied to the elastic member may provide enough force to overcome a retractive force of the elastic member when the latent polymer is at a temperature below a softening point of the latent polymer, yet the amount of latent polymer may be small enough to allow the laminate to retract into an elastic, gathered structure when the laminate is heated to a softening point of the latent polymer. The laminate may be incorporated into a variety of articles including personal care garments and cleaning cloths.

    摘要： The present invention comprises a continuous feed spun bonded laminate having improved elastic properties measured at body temperature. The laminate comprises at least one first and second nonelastic layers between which is sandwiched at least one elastic layer, the elastic layer being comprised of a triblock polystyrene-poly(ethylene/propylene)-polystyrene (“SEPS”) copolymer having a number average molecular weight of about 81,000 g/mol. The weight percent of styrene is approximately 18% and the weight percent of ethylene/propylene is approximately 82%. The molecular weight increase in the EP block, while holding the molecular weight of the styrene block constant, increases the entanglement density, polymer chain persistence length and the relaxation time. The resulting laminate load decay rate and load loss measurements over a period of 12 hours at body temperature showed marked improvement over known CFSBL product. The laminate is particularly useful as side panel material in training pants because of the resistance to sagging at body temperature.

    摘要： A technique for imparting latent elasticity to components of an absorbent article is provided. More specifically, a latent elastic film that contains a crosslinkable semi-crystalline polyolefin is initially incorporated into an absorbent article. The film is not highly elastic prior to crosslinking and is thus dimensionally stable. Consequently, the film need not be maintained in a mechanically stretched condition during attachment to other components of the absorbent article, which provides for greater freedom in the location and manner in which the components are attached together. Once incorporated into the absorbent article, the semi-crystalline polyolefin is crosslinked to form a three-dimensional network having elastic memory. The film may also be heat activated, either through crosslinking or an additional step, to cause the film to shrink and further improve its stretch characteristics.
