  • Patent number: 5666787
    Abstract: A tissue package comprising a plurality of tissues and a dispensing package. The plurality of tissues is compressed in two discrete stages, each of which stage can be released independently from the other. The first stage of compression is less than the second stage compression. The user releases the second stage of compression, whereby the tissues can expand up to the first stage of compression. The user releases the first stage of compression just before installing the plurality of tissues into a dispensing package or dispenses the tissues through a restraint while they are held in the first stage compression.

  • Patent number: 5656746
    Abstract: A temporary wet strength polymer and compositions for paper products, e.g., toilet tissue, is disclosed. The temporary wet strength polymer is the oxidation product of an esterified polyhydroxy polymer, more preferably of an esterified polysaccharide. The esterified polymer compound is formed by reacting the polyhydroxy polymer with a 1,2-disubstituted alkene compound that has at least one carboxylic acid group. The temporary wet strength polymer provides paper products having an initial wet strength that enables use of the product in the moistened condition, along with a suitable wet strength decay rate.

  • Patent number: 5648262
    Abstract: The transfer of a textile dye from a dyed fabric to another fabric during washing or rinsing is inhibited by adding an enzyme exhibiting peroxidase activity or an enzyme exhibiting a suitable oxidase activity to the wash liquor in which said fabrics are washed and/or rinsed. Peroxidase is produced extracellularly by some strains of Bacillus pumilus. The novel peroxidase preparation from B. pumilus is a microperoxidase, i.e. it contains hemopeptide as an active component. The preparation has improved stability at high temperature, at high pH and at high concentrations of hydrogen peroxide. It can be produced without undesired catalase activity.

  • Patent number: 5563179
    Abstract: Absorbent foams materials that are capable of acquiring and distributing aqueous fluids, especially discharged body fluids such as urine. These absorbent foams combine relatively high capillary absorption pressures and capacity-per-weight properties that allow them to acquire fluid, with or without the aid of gravity. These absorbent foams also give up this fluid efficiently to higher absorption pressure storage materials, including foam-based absorbent fluid storage components, without collapsing. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs).

    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.
