  • Publication number: 20180161476
    Abstract: The present disclosure is directed to a closed cell foam matrix for delivering oxygen containing a superabsorbent material oxygen entrapped within the superabsorbent material. The superabsorbent material has at least 15 percent by mass monoethylenically unsaturated carboxylic, sulphonic or phosphoric acid or salts thereof, an acrylate or methacrylate ester that contains an alkoxysilane functionality, and a copolymerizable hydrophilic glycol containing ester monomer. To produce the closed cell foam matrix for delivering oxygen, an alkali hydroxide catalyst is added to the superabsorbent material to form a hydrogel layer. Then, an oxygen precursor is added to the hydrogel layer. The hydrogel layer is heated to produce oxygen by reacting the alkali hydroxide catalyst and the oxygen precursor thereby entrapping the oxygen in the formed closed cell foam matrix.

  • Publication number: 20100155004
    Abstract: Fibrous articles are disclosed containing an additive composition. The additive composition, for instance, may include a water-soluble film forming component and water-soluble modifying components that is deposited at least at the surface of a fibrous web. In some aspects, the additive composition includes polymers that demonstrate a certain LCST and melting temperature. In another aspect, the additive composition is applied to the fibrous web during the heated drying phase, such as with a Yankee dryer. The fibrous web with additive composition is then creped. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.
