摘要:
An absorbent structure expands to a greater extent along one surface than along an opposite surface when in the presence of a liquid. The absorbent structure may include a single layer, or two or more layers intimately bonded to one another. When in the presence of a liquid, the more expandable surface causes an increase in concavity in the X-Y plane of the structure, with the concavity being in the direction of the less expandable surface. One or both surfaces can be treated to adjust the respective level of expandability. By inducing a formed shape upon hydration swelling, a trough shape can be generated to facilitate absorbent properties, containment, and fit. The invention includes absorbent articles having such an absorbent structure incorporated therein.
摘要:
A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.
摘要:
A textured coform nonwoven web is provided that includes a matrix of meltblown fibers and an absorbent material. The coform nonwoven web is textured in that it includes first offsets that extend from the coform web. Further, the first offsets are themselves textured in that upper surfaces of the first offsets include a foundation texture. A continuous region from which the offsets extend further includes a secondary texture that may or may not be different from the foundation texture. The offsets may further include side walls that include a side wall texture. The side wall texture may or may not be different than both the foundation texture and the secondary texture.
