  • Patent number: 5635028
    Abstract: Soft creped tissue paper products comprising papermaking fibers and a crepe facilitating composition are disclosed. The crepe facilitating composition comprises a bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the bonding inhibitor is a quaternary ammonium compound. The use of a bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped papermaking process comprising the addition of the crepe facilitating composition is also disclosed. The crepe facilitating composition offers the potential to improve production capacity.

  • Patent number: 4865596
    Abstract: The present invention relates to composite absorbent structures suitable for incorporation into absorbent articles such as sanitary napkins, diapers, incontinent devices, training pants and the like. Such structures comprise webs of entangled blown microfibers, substantially nonabsorbent crimped staple fibers, a fluid control system comprising hydrophilic particulate entities and also optionally containing certain types of hydrogel-forming polymeric gelling agent particles, and a hydrophilizing agent. Such composite web structures of this construction have especially desirable comfort, integrity and fluid handling characteristics.

  • Patent number: 4673402
    Abstract: The present invention provides absorbent articles, such as disposable diapers, which utilize substantially water-insoluble hydrogel material to enhance the absorbent capacity of such articles. In these articles, the hydrogel material, combined in particulate form with hydrophilic fiber material, is primarily placed in a lower fluid storage layer of the absorbent core of the article. Such a fluid storage lower layer of the absorbent core is placed underneath an upper, preferably larger, fluid acquisition/distribution layer containing little or no hydrogel. This lower fluid storage layer is positioned in such a manner that at least about 75% of the hydrogel in the lower layer is found in the front two-thirds of the absorbent article and such that at least about 55% of the hydrogel in the lower layer is found in the front half of the absorbent article. Absorbent articles of this type make especially effective and efficient use of the hydrogel material and may also provide a diaper rash control benefit.

    Assignee: The Procter & Gamble Company
    Inventors: Paul T. Weisman, Dawn I. Houghton, Dale A. Gellert
  • Patent number: 4610678
    Abstract: Absorbent structures comprising a mixture of hydrophilic fibers and discrete particles of a water insoluble hydrogel are disclosed. The fiber/hydrogel ratios range from about 30:70 to about 98:2. The absorbent structures have a density of from about 0.15 g/cm.sup.3 to about 1 g/cm.sup.3. The structures are flexible, and have superior absorption capacities for water and body fluids.

  • Patent number: 4469746
    Abstract: Fibrous webs comprising fibers coated with a continuous film comprising silica have excellent absorbent and wicking properties. The fibers themselves may be hydrophilic (e.g., cellulose) or hydrophobic (e.g., a polyolefin or a polyester).

    Assignee: The Procter & Gamble Company
    Inventors: Paul T. Weisman, Herbert L. Retzsch
  • Patent number: 4468428
    Abstract: Fibrous absorbent webs having a low density (about 0.01 g/cm.sup.3 to about 0.15 g/cm.sup.3) and comprising at least about 50% hydrophilic microfibers, such as cellulose microfibers, having a diameter of from about 0.01 microns to about 15 microns possess superior absorption properties, especially under typical usage conditions.Hydrophobic microfibers may also be used, provided such fibers are hydrophilized before or after web formation.
