    Abstract: Method for increasing the absorbency of cellulosic fibers by a high temperature wet treatment comprising heating the fibers in a water bath at temperatures within the range of about 95.degree. C. to 100.degree. C. for periods ranging from about one to sixty minutes. Absorbency of the treated fibers is thus increased by more than 2% of the corresponding untreated fibers as measured by the Syngyna Test Method. By employing such materials in catamenial tampons, sanitary napkins or the like, the amount of absorbent material may be decreased by 10% or more relative to the corresponding, untreated absorbent material, without adversely affecting the absorbent characteristics thereof.

    Abstract: Metal complexes of 8-hydroxyquinoline and polymeric water-insoluble but water-swellable cross-linked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules and a process for preparing same. Such complexes are particularly suited for use as algicides, fungicides, slimicides, and bacteriocides in the treatment of water such as in gravity filtration systems, canisters or packed columns having the advantage of rapid throughput. The complexes may be prepared by adsorbing the hydroxyquinoline onto the cross-linked N-vinyllactam or N-alkyl-N-vinylamide in the form of porous beads or porous granules and subsequently forming the metallic complex in solution.
