  • Patent number: 6838154
    Abstract: There is provided a resilient, three dimensional material having fibrous texture and appearance and capable of fluid handling. It consists of a top surface and a bottom surface wherein fiber-like elements typically extend from one surface to the other forming flat to undulating surfaces characterized by a multiplicity of interconnected fluid passageways. Deformed, discontinuous film-like or encapsulated regions connect fiber-like elements and stabilize the material. The material of this invention is unique based on the three principle characteristics which are communicated in this application: 1) ff(?)<0.87, 2) SA/VV<186 cm2/cm3, and 3) caliper<0.150 inches. This material is useful for a number of purposes, such as for use as a liner for personal care products like diapers, absorbent underpants, swim wear, feminine hygiene products, adult incontinence products and the like.

  • Patent number: 6759567
    Abstract: A personal care product that has a liquid impermeable backsheet, a liquid permeable topsheet, and an absorbent composite located between the topsheet and backsheet. The absorbent composite has an upper layer made of synthetic fiber with at most 20 weight percent pulp and the upper layer has a density between about 0.03 and 0.15 g/cc and a basis weight between about 20 to 75 gsm. The composite has a lower layer having from 80 to 95 weight percent pulp, at most 20 weight percent binder, and has a density greater than the upper layer and between 0.06 and 0.20 g/cc, and a basis weight between 120 and 200 gsm.

  • 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: 6410823
    Abstract: A film cover for use in absorbent materials such as feminine care products, surgical drapes, fenestration reinforcement, absorbent pads and the like including a polymeric film having a top planar surface and a bottom planar surface and forming a plurality of apertures, at least a portion of which have an aperture region having a higher wettability than a portion of the top planar surface of the polymeric film.

  • Patent number: 6221460
    Abstract: Disclosed herein is a liquid absorbent material that is particularly useful as a liner material for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like. The material contains a plurality of peaks across its surface at spaced-apart intervals separated by channels. Disposed within the peaks is a liquid absorbing material capable of absorbing body exudates and liquids in general. Due to the materials and the nature of the construction of the present invention, when used as a liner material for personal care absorbent articles such as diapers, it tends to reduce the total surface area in contact with the infant's skin and it also provides a plurality of air channels within the diaper from the front waistband to the back waistband of the diaper thereby providing a path for increased air circulation.

  • Patent number: 6172276
    Abstract: There is provided a distribution material for personal care products which is a fabric which wicks artificial menses according to a horizontal wicking test a distance of about 1 inch in less than about 1.5 minutes. Materials meeting this performance criteria generally have a pore size distribution with a high percentage (usually more than 50 percent) of pore diameters between about 80 and 400 microns and a density below about 0.15 g/cc.
