  • Publication number: 20210275364
    Abstract: The present disclosure relates to absorbent article incorporating elastomeric laminates that may be formed by stretching and joining an elastic strand with either or both first and second substrates using an adhesive. The elastic strands may be sourced from a wound supply, such as a beam of beamed elastic strands. The beam may be treated with a control layer to reducing blocking when the plurality of elastic strands are on the beam and to provide for reliable unwinding. The control layer may be absorbed into an adhesive once the elastic strands are joined with the first and second substrates with the adhesive to form the elastomeric laminate.

  • Patent number: 5599335
    Abstract: Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a Saline Flow Conductivity (SFC) value of at least about 30.times.10.sup.-7 cm.sup.3 sec/g; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) a basis weight of at least about 10 gsm. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel-continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.

  • Patent number: 5562646
    Abstract: Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100% by weight and providing a gel-continuous fluid transportation zone when in a swollen state. This hydrogel-forming absorbent polymer has: (a) a porosity of at least about 0.15; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); (c) a basis weight of at least about 10 gsm; and (d) optionally, but preferably, a Saline Flow Conductivity (SFC) value of at least about 30.times.10.sup.-7 cm.sup.3 sec/g. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel-continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.
