  • Publication number: 20100174260
    Abstract: A personal care absorbent article such as a disposable diaper, sanitary pad or tampon, wound dressing or bandage which includes a nonwoven web material made from a plurality of polymeric fibers having at least one treatment chemistry suitable for modifying at least one characteristic of a high viscoelasticity fluid upon contact with the high viscoelasticity fluid. In accordance with one particularly preferred embodiment, the treatment chemistry is suitable for immobilizing the high viscoelasticity fluid within the nonwoven web material.

  • Patent number: 6723892
    Abstract: There is provided an absorbent system that not only takes in fluid, but then transfers that fluid further beneath the first composite. This is achieved in this invention through paired permeability, capillarity, and void volume of the first and second composites. The invention is an absorbent system composed of at least two absorbent composites that have complementary structural/surface energy characteristics. Such an absorbent system has a first absorbent Composite A which has a first permeability, a first capillarity, and a first void volume and at least one second absorbent Composite B which has a second capillarity and a second porosity multiplied by second thickness. The first absorbent Composite A is in liquid communication or contact with at least one second absorbent Composite B, such that the first absorbent Composite A, and the second absorbent Composite B have a fluid partitioning amount in Composite A, a third triple intake time (IT3) and a rewet value.

  • Patent number: 6627789
    Abstract: There is provided an intake/retention/transfer material for personal care products like feminine hygiene products, which is a heterogeneous composite containing between 5 and 25 weight percent of a superabsorbent or gelling material and having a density less than 0.17 g/cc. A more particular embodiment contains less than 20 weight percent and a still more particular embodiment contains 15 weight percent or less of a superabsorbent or gelling material. Also provided are absorbent articles which contain the class of intake/transfer materials mentioned above along with additional absorbent layers such that the absorption of a menses simulant provides fluid partitioning of less than 72% of fluid in the intake/transfer/retention composite. Additionally said composite should have retention capacity values greater than 2.7 g/g.

  • Patent number: 6610903
    Abstract: There is provided a fluid management material for personal care products which distributes artificial menses according to the gush/distribution test taught herein such that it has a distribution ratio of at least about 0.06. Its preferred that the fluid management material be part of an absorbent materials system having a first fibrous layer, a middle layer adjacent the first layer having hydrophilic oriented surface fibers, and a second fibrous layer adjacent the middle layer. In a personal care product configuration the oriented surface fibers result in a distribution ratio of at least 0.06 where the distribution ratio is a ratio of average of the mass of two end zones of a product divided by the mass of the center zone.
